Find facts and statistics about stroke in the United States.
- In 2018, 1 in every 6 deaths from cardiovascular disease was due to stroke. 1
- Someone in the United States has a stroke every 40 seconds. Every 4 minutes, someone dies of stroke. 2
- Every year, more than 795,000 people in the United States have a stroke. About 610,000 of these are first or new strokes. 2
- About 185,000 strokes&mdashnearly 1 of 4&mdashare in people who have had a previous stroke. 2
- About 87% of all strokes are ischemic strokes, in which blood flow to the brain is blocked. 2
- Stroke-related costs in the United States came to nearly $46 billion between 2014 and 2015. 2 This total includes the cost of health care services, medicines to treat stroke, and missed days of work.
- Stroke is a leading cause of serious long-term disability. 2 Stroke reduces mobility in more than half of stroke survivors age 65 and over. 2
Stroke Statistics by Race and Ethnicity
- Stroke is a leading cause of death for Americans, but the risk of having a stroke varies with race and ethnicity.
- Risk of having a first stroke is nearly twice as high for blacks as for whites, 2 and blacks have the highest rate of death due to stroke. 1
- Though stroke death rates have declined for decades among all race/ethnicities, Hispanics have seen an increase in death rates since 2013. 1
Stroke Risk Varies by Age

Early Action Is Important for Stroke
Know the warning signs and symptoms of stroke so that you can act fast if you or someone you know might be having a stroke. The chances of survival are greater when emergency treatment begins quickly.
- In one survey, most respondents&mdash93%&mdashrecognized sudden numbness on one side as a symptom of stroke. Only 38% were aware of all major symptoms and knew to call 9-1-1 when someone was having a stroke. 4
- Patients who arrive at the emergency room within 3 hours of their first symptoms often have less disability 3 months after a stroke than those who received delayed care. 4
Americans at Risk for Stroke
High blood pressure, high cholesterol, smoking, obesity, and diabetes are leading causes of stroke. 1 in 3 US adults has at least one of these conditions or habits. 2
I turn 65 in a few months. When should I sign up for Medicare?
En español | If you already receive Social Security benefits, Social Security will automatically sign you up for Medicare Part A and Part B — though you can decline Part B enrollment if you want to. Otherwise, you need to apply for Medicare. The best time to do that depends entirely on your own situation. Broadly, there are two options:
During your Initial Enrollment Period (IEP)
This lasts for seven months, of which the fourth one is the month in which you turn 65. For example, if your 65th birthday is in June, your IEP begins March 1 and ends Sept. 30. (Exception: If your birthday falls on the first day of the month, the whole IEP moves forward one month. For example, if your birthday is June 1, your IEP begins Feb. 1 and ends Aug. 31.)
To avoid late penalties and delayed coverage, you need to sign up for Medicare during your IEP in these circumstances:
- You have no other health insurance
- You have health insurance that you bought yourself (not provided by an employer)
- You have retiree benefits from a former employer (your own or your spouse’s)
- You have COBRA coverage that extends the insurance you or your spouse received from an employer while working
- You have veterans’ benefits from the Department of Veterans Affairs (VA) health system (but no insurance provided by a current employer)
- You’re in a nonmarital domestic relationship with someone of the same or opposite sex and you are covered by his or her employer insurance
If you enroll during the first three months of your IEP, your Medicare coverage begins on the first day of the month you turn 65 (or the first day of the previous month if your birthday falls on the first day of a month). If you sign up during the fourth month, coverage begins on the first day of the following month. But if you leave it until the fifth, sixth or seventh month, coverage will be delayed by two or three months. For example, if your birthday is in June and you sign up in September (the last month of your IEP), coverage will not begin until Dec. 1.
During your IEP you can also sign up for Medicare Part D prescription drug coverage — although you may not need to if you have “creditable” drug coverage from retiree benefits, COBRA or the VA. (“Creditable” means that Medicare considers the coverage as good as or better than Part D.) You also have the option to switch your coverage from Original Medicare (parts A and B) to a Medicare Advantage plan (such as an HMO or PPO) during your IEP.
During a Special Enrollment Period (SEP)
This SEP is available only if you have health insurance (beyond the end of your IEP) from an employer for which you or your spouse actively works. It allows you to delay enrolling in Part B (and avoid its monthly premiums) until the employment or the coverage ends — whichever occurs first.
The SEP actually lasts throughout the time you have coverage from current employment and for up to eight months after it ends. If you enroll at any point during this time frame, your Medicare coverage will begin on the first day of the following month, and you will not be liable for late penalties — regardless of how old you are when you finally sign up.
Be aware that an IEP always trumps an SEP if the two should happen to overlap. For example, if your IEP ends on Aug. 31, and you retire on the same date, you will not be entitled to an SEP. Therefore, if you delayed enrollment until after Aug. 31, you would not be able to sign up until the following general enrollment period (Jan. 1 to March 31) and your coverage would not begin until July 1 — so you would be left for almost a year without coverage. Even if you signed up during the final months of your IEP, your coverage would still be delayed by two or three months. But, to continue this example, if you retired on Sept. 1, under the rules of the SEP, you could enroll in August and receive Medicare starting Sept. 1 with no loss of coverage.
If you will lose prescription drug coverage when the employer plan ends, you can sign up with a Medicare Part D drug plan. You will not be liable for late penalties if you enroll within two months of losing the employer coverage.
Two other Medicare enrollment scenarios have different rules.
If you live outside the United States: If you live outside the United States, without either you or your spouse working, you have a difficult decision to make. You can either sign up for Part B and pay its monthly premiums, even though you can’t use Medicare services abroad — or you can wait to sign up until you return to the U.S. and then face getting hit with permanent late penalties and delayed coverage.
But if you or your spouse is working, and you have health insurance from an employer or are covered under the public national health system of the country where you live, you have the right to delay Medicare enrollment until the employment ends. You will then be entitled to the same SEP explained earlier in this section.
There is another exception: If you are not fully insured — that is, if you are not entitled to Part A benefits without paying premiums for them — you cannot sign up for either Part A or Part B while overseas. You can enroll within three months of returning to the United States to live permanently. In this situation, coverage begins on the first day of the month after you enroll, and you do not risk late penalties, regardless of how old you are or how long you’ve lived abroad.
Otherwise, if you want to sign up for Medicare while living outside the United States, you can apply through your nearest U.S. embassy or consulate. The State Department has an online directory where you can find contact information U.S. diplomatic stations in each country.
Part D drug coverage has different rules. On your return to live permanently in the United States, you’re entitled to a special enrollment period of up to three months (if you turned 65 abroad) or up to two months (if you turned 65 before leaving the U.S.) to sign up with a Part D drug plan without risking late penalties. Coverage begins on the first day of the month after you enroll.
If you are in prison: If you turn 65 while living in prison or any other type of correctional institution, you can either enroll in Part B during your IEP and pay monthly premiums, even though you can’t use Medicare services while incarcerated — or wait until you’re released and then face permanent late penalties and delayed coverage.
Similarly, if you’re imprisoned after age 65 and already enrolled in Medicare, you’re expected to continue paying premiums to avoid penalties when you come out.
Part D drug coverage has different rules. On your release, you’re entitled to a special enrollment period of up to three months (if you turned 65 in prison) or up to two months (if you turned 65 before going to prison) to sign up with a Part D drug plan and avoid late penalties. Coverage begins on the first day of the month after you enroll.

2001–2004: Founding Edit
In 2001, Elon Musk conceptualized Mars Oasis, a project to land a miniature experimental greenhouse and grow plants on Mars.    He announced that the project would be "the farthest that life's ever traveled" in an attempt to regain public interest in space exploration and increase NASA's budget.    Musk tried to purchase cheap rockets from Russia but returned empty-handed after failing to find rockets for an affordable price.  
On the flight home Musk realized that he could start a company that could build the affordable rockets he needed.  By applying vertical integration,  using cheap commercial off-the-shelf components when possible,  and adopting the modular approach of modern software engineering, Musk believed SpaceX could significantly cut launch price. 
In early 2002, Musk started to look for staff for his new space company, soon to be named SpaceX. Musk approached rocket engineer Tom Mueller (later SpaceX's CTO of propulsion), and invited him to become his business partner. Mueller agreed to work for Musk, and thus SpaceX was born.  SpaceX was first headquartered in a warehouse in El Segundo, California. By November 2005, the company had 160 employees.  Musk personally interviewed and approved all of SpaceX's early employees, even going so far as convincing Larry Page to transfer a Google employee from San Francisco to Los Angeles so that the employee's spouse, a potential SpaceX hire, would take the job. 
Musk has stated that one of his goals with SpaceX is to decrease the cost and improve the reliability of access to space, ultimately by a factor of ten. 
2005–2009: Falcon 1 and first orbital launches Edit
SpaceX developed its first orbital launch vehicle, the Falcon 1, with private funding.   The Falcon 1 was an expendable two-stage-to-orbit small-lift launch vehicle. The total development cost of Falcon 1 was approximately US$90 million  to US$100 million. 
In 2005, SpaceX announced plans to pursue a human-rated commercial space program through the end of the decade, a program which would later become the Dragon spacecraft.  In 2006, NASA announced that the company was one of two selected to provide crew and cargo resupply demonstration contracts to the ISS under the COTS program. 
The first two Falcon 1 launches were purchased by the United States Department of Defense under a program that evaluates new US launch vehicles suitable for use by DARPA.    The first three launches of the rocket, between 2006 and 2008, all resulted in failures. These failures almost ended the company as Musk had planned and financing to cover the costs of three launches Tesla, SolarCity, and Musk personally were all nearly bankrupt at the same time as well  Musk was reportedly "waking from nightmares, screaming and in physical pain" because of the stress. 
However, things started to turn around when the first successful launch was achieved shortly after with the fourth attempt on 28 September 2008. Musk split his remaining $30 million between SpaceX and Tesla, and NASA awarded the first Commercial Resupply Services (CRS) contract to SpaceX in December, thus financially saving the company.  Based on these factors and the further business operations they enabled, the Falcon 1 was soon after retired following its second successful, and fifth total, launch in July 2009 this allowed SpaceX to focus company resources on the development of a larger orbital rocket, the Falcon 9.  Gwynne Shotwell was also promoted to company president at this time, for her role in successfully negotiating the CRS contract with NASA. 
2010–2012: Falcon 9, Dragon, and NASA contracts Edit
SpaceX originally intended to follow its light Falcon 1 launch vehicle with an intermediate capacity vehicle, the Falcon 5.  SpaceX instead decided in 2005 to proceed with the development of the Falcon 9, a reusable heavier lift vehicle. Development of the Falcon 9 was accelerated by NASA, which committed to purchase several commercial flights if specific capabilities were demonstrated. This started with seed money from the Commercial Orbital Transportation Services (COTS) program in 2006.  The overall contract award was US$278 million to provide development funding for the Dragon spacecraft, Falcon 9, and demonstration launches of Falcon 9 with Dragon.  As part of this contract, the Falcon 9 launched for the first time in June 2010 with the Dragon Spacecraft Qualification Unit, using a mockup of the Dragon spacecraft. The first operational Dragon spacecraft was launched in December 2010 aboard COTS Demo Flight 1, the Falcon 9's second flight, and safely returned to Earth after two orbits, completing all its mission objectives.  By December 2010, the SpaceX production line was manufacturing one Falcon 9 and Dragon every three months. 
In April 2011, as part of its second-round Commercial Crew Development (CCDev) program, NASA issued a US$75 million contract for SpaceX to develop an integrated launch escape system for Dragon in preparation for human-rating it as a crew transport vehicle to the ISS.  In August 2012, NASA awarded SpaceX a firm, fixed-price Space Act Agreement (SAA) with the objective of producing a detailed design of the entire crew transportation system. This contract includes numerous key technical and certification milestones, an uncrewed flight test, a crewed flight test, and six operational missions following system certification. 
In early 2012, approximately two-thirds of SpaceX stock was owned by Musk  and his 70 million shares were then estimated to be worth US$875 million on private markets,  valuing SpaceX at US$1.3 billion.  In May 2012, with the Dragon C2+ launch Dragon became the first commercial spacecraft to deliver cargo to the International Space Station.  After the flight, the company private equity valuation nearly doubled to US$2.4 billion or US$20/share.   By that time, SpaceX had operated on total funding of approximately $1 billion over its first decade of operation. Of this, private equity provided approximately $200 million, with Musk investing approximately $100 million and other investors having put in about $100 million. 
SpaceX's active reusability test program began in late 2012 with testing low-altitude, low-speed aspects of the landing technology.  The Falcon 9 prototypes performed vertical takeoffs and landings (VTOL). High-velocity, high-altitude tests of the booster atmospheric return technology began in late 2013. 
2013–2015: Commercial launches and rapid growth Edit
SpaceX launched the first commercial mission for a private customer in 2013. In 2014, SpaceX won nine contracts out of the 20 that were openly competed worldwide.  That year Arianespace requested that European governments provide additional subsidies to face the competition from SpaceX.   Beginning in 2014, SpaceX capabilities and pricing also began to affect the market for launch of U.S. military payloads, which for nearly a decade was dominated by the large U.S. launch provider United Launch Alliance (ULA).  The monopoly had allowed launch costs by the U.S. provider to rise to over US$400 million over the years. 
In January 2015, SpaceX raised US$1 billion in funding from Google and Fidelity, in exchange for 8.33% of the company, establishing the company valuation at approximately US$12 billion.  The same month SpaceX announced the development of a new satellite constellation, called Starlink, to provide global broadband internet service. The following June, the company asked the federal government for permission to begin testing for the project, aiming to build a constellation of 4,425 satellites. 
The Falcon 9 had its first major failure in late June 2015, when the seventh ISS resupply mission, CRS-7 exploded two minutes into the flight.  The problem was traced to a failed 2-foot-long steel strut that held a helium pressure vessel, which broke free due to the force of acceleration. This caused a breach and allowed high-pressure helium to escape into the low-pressure propellant tank, causing the failure. 
2015–2017: Reusability milestones Edit
SpaceX first achieved a successful landing and recovery of a first stage in December 2015 with Falcon 9 Flight 20.  In April 2016, the company achieved the first successful landing on the autonomous spaceport drone ship (ASDS) Of Course I Still Love You in the Atlantic Ocean.  By October 2016, following the successful landings, SpaceX indicated they were offering their customers a 10% price discount if they choose to fly their payload on a reused Falcon 9 first stage. 
In early September 2016, a Falcon 9 exploded during a propellant fill operation for a standard pre-launch static fire test.  The payload, the Amos-6 communications satellite valued at US$200 million, was destroyed.  The explosion was caused by the liquid oxygen that is used as propellant turning so cold that it solidified and ignited with carbon composite helium vessels.  Though not considered an unsuccessful flight, the rocket explosion sent the company into a four-month launch hiatus while it worked out what went wrong. SpaceX returned to flight in January 2017. 
On 30 March 2017, SpaceX launched a returned Falcon 9 for the SES-10 satellite. This was the first time a re-launch of a payload-carrying orbital rocket went back to space.  The first stage was recovered again, also making it the first landing of a reused orbital class rocket. 
2017–2018: Leading global commercial launch provider Edit
In July 2017, the Company raised US$350 million for a valuation of US$21 billion.  In 2017, SpaceX achieved a 45% global market share for awarded commercial launch contracts.  By March 2018, SpaceX had more than 100 launches on its manifest representing about US$12 billion in contract revenue.  The contracts included both commercial and government (NASA/DOD) customers.  This made SpaceX the leading global commercial launch provider measured by manifested launches. 
In 2017, SpaceX formed a subsidiary, The Boring Company,  and began work to construct a short test tunnel on and adjacent to the SpaceX headquarters and manufacturing facility, utilizing a small number of SpaceX employees,  which was completed in May 2018,  and opened to the public in December 2018.  During 2018, The Boring Company was spun out into a separate corporate entity with 6% of the equity going to SpaceX, less than 10% to early employees, and the remainder of the equity to Elon Musk. 
2019–present: Starship, Starlink, and first crewed launches Edit
On 11 January 2019, SpaceX announced it would lay off 10% of its workforce in order to help finance the Starship and Starlink projects.  Construction of initial prototypes and tests for Starship started in early 2019 in Florida and Texas. All Starship construction and testing moved to the new SpaceX South Texas launch site later that year. In May 2019 SpaceX also launched the first large batch of 60 Starlink satellites, beginning the deployment of what would become the world's largest commercial satellite constellation the following year. 
SpaceX raised a total of US$1.33 billion of capital across three funding rounds in 2019.  By May 2019, the valuation of SpaceX had risen to US$33.3 billion  and reached US$36 billion by March 2020. 
On 30 May 2020, SpaceX successfully launched two NASA astronauts (Doug Hurley and Bob Behnken) into orbit on a Crew Dragon spacecraft during Crew Dragon Demo-2, making SpaceX the first private company to send astronauts to the International Space Station and marking the first crewed launch from American soil in 9 years.   The mission launched from Kennedy Space Center Launch Complex 39A (LC-39A) of the Kennedy Space Center in Florida. 
On 19 August 2020, after a US$1.9 billion funding round, one of the largest single fundraising pushes by any privately held company, SpaceX's valuation increased to US$46 billion.    In February 2021, SpaceX raised an additional US$1.61 billion in an equity round from 99 investors  at a per share value of approximately $420,  raising the company valuation to approximately US$74 billion. It has raised a total of more than US$6 billion in equity financing to date. The capital-intensive phase in recent years has been principally to support the operational fielding of the Starlink satellite constellation and the development and manufacture of the Starship launch vehicle. 
By 2021, SpaceX had entered into agreements with Google Cloud Platform and Microsoft Azure to provide on-ground compute and networking services for Starlink. 
Summary of achievements Edit
Major achievements of SpaceX are in the reuse of orbital-class launch vehicles and cost reduction in the space launch industry. Most notable of these being the continued landings and relaunches of the first stage of Falcon 9 following a multi-year program to develop the reusable technology. As of May 2021, SpaceX has used two separate first-stage boosters, B1049 and B1051, nine and ten times respectively.  Elon Musk has gone on to say they will continue to push the fleet leader, B1051, past the original goal of ten flights.  SpaceX is a private space company with most of its achievements the result of self-funded development efforts, not developed by traditional cost-plus contracting of the US government. As a result, many of its achievements are also considered as firsts by a private company.

Launch vehicles Edit
SpaceX has developed three launch vehicles. The small-lift Falcon 1 was the first launch vehicle developed and was retired in 2009. The medium-lift Falcon 9 and the heavy-lift Falcon Heavy are both operational. The Falcon 1 was a small rocket capable of placing several hundred kilograms into low Earth orbit. It launched five times between 2006 and 2009, of which 2 successfully.  It functioned as an early test-bed for developing concepts and components for the larger Falcon 9.  The Falcon 1 was the first privately funded, liquid-fueled rocket to reach orbit. 
Falcon 9 is an medium-lift launch vehicle capable of delivering up to 22,800 kilograms (50,265 lb) to orbit, competing with the Delta IV and the Atlas V rockets, as well as other launch providers around the world. It has nine Merlin engines in its first stage. The Falcon 9 v1.0 rocket successfully reached orbit on its first attempt on 4 June 2010. Its third flight, COTS Demo Flight 2, launched on 22 May 2012, and was the first commercial spacecraft to reach and dock with the International Space Station (ISS).  The vehicle was upgraded to Falcon 9 v1.1 in 2013, Falcon 9 Full Thrust in 2015, and finally to Falcon 9 Block 5 in 2018. The first stage of Falcon 9 is designed to retropropulsively land, be recovered, and reflown. 
The Falcon Heavy is a heavy-lift launch vehicle capable of delivering up to 63,800 kg (140,700 lb) to Low Earth orbit (LEO) or 26,700 kg (58,900 lb) to geosynchronous transfer orbit (GTO). It uses three slightly modified Falcon 9 first stage cores with a total of 27 Merlin 1D engines.   The Falcon Heavy successfully flew its inaugural mission on 6 February 2018, launching Musk's personal Tesla Roadster into heliocentric orbit 
Both the Falcon 9 and Falcon Heavy are certified to conduct launches for the National Security Space Launch (NSSL).   As of 18 June 2021, the Falcon 9 and Falcon Heavy have been launched 125 times, resulting in 123 full mission successes, one partial success, one in-flight failure. In addition, a Falcon 9 experienced a pre-flight failure prior to a static fire test in 2016.  
Rocket engines Edit
Since the founding of SpaceX in 2002, the company has developed several rocket engines — Merlin, Kestrel, and Raptor for use in launch vehicles, Draco for the reaction control system of the Dragon series of spacecraft, and SuperDraco for abort capability in Crew Dragon.
Merlin is a family of rocket engines that uses liquid oxygen (LOX) and RP-1 propellants in a gas-generator power cycle. Merlin was first used to power the Falcon 1's first stage, and is now used on both stages of the Falcon 9 and Falcon Heavy vehicles. The Merlin engine uses a pintle injector that provides deep-throttle capability used during Falcon 9 landings. Propellants are fed via a single shaft, dual impeller turbopump.
Kestrel is a LOX/RP-1 pressure-fed rocket engine and was used as the Falcon 1 rocket's second stage main engine. It is built around the same pintle architecture as SpaceX's Merlin engine but does not have a turbopump, and is fed only by tank pressure. The engine is ablatively cooled in the chamber and throat, and is radiatively cooled on the exhaust nozzle. The Kestrel's nozzle is fabricated from a high strength niobium alloy.  
Draco is a hypergolic liquid-propellant rocket engine that utilizes monomethyl hydrazine fuel and nitrogen tetroxide oxidizer. Each Draco thruster generates 400 N (90 lbf) of thrust.  They are used on the reaction control system of the Dragon and Dragon 2 spacecraft. 
SuperDraco is a hypergolic liquid-propellant rocket engine that, like Draco, uses monomethyl hydrazine and nitrogen tetroxide propellants. Eight SuperDraco engines provide launch escape capability for crewed Dragon 2 spacecraft during an abort scenario. Each SuperDraco engine produces 73 kN (16,000 lbf) of thrust. Initial concepts for the Crew Dragon spacecraft used the SuperDraco engines to perform a retropropulsive landing on land, however, these were scrapped in 2017 when it was decided to perform a traditional parachute descent and splashdown at sea. 
Raptor is a new family of liquid oxygen and liquid methane-fueled full-flow staged combustion cycle engines to power the first and second stages of the in-development Starship launch system.  Development versions were test-fired in late 2016.  On 3 April 2019, SpaceX conducted a static fire test in Texas on its Starhopper vehicle, which ignited the engine while the vehicle remained tethered to the ground.  In 2019, Raptor flew for the first time, powering the Starhopper vehicle to an altitude of 20 m (66 ft).  SpaceX continues to conduct further test flights of the Starship vehicle in 2020 and 2021. 
Dragon spacecraft Edit
SpaceX has developed the Dragon spacecraft to transport cargo and crew to the International Space Station. The first version of Dragon, used only for cargo, was first launched in 2010.  The currently operational second generation Dragon spacecraft, known as Dragon 2, conducted its first flight, without crew, to the ISS in early 2019, followed by a crewed flight of Dragon 2 in 2020.   Dragon 2 is capable of transporting a crew of up to four in NASA configuration to low Earth orbit. 
On 7 December 2020 SpaceX flew the cargo variant of Dragon 2 to the Space Station for 100th successful Falcon 9 flight. This is the first launch for this redesigned cargo Dragon, and also the first mission for SpaceX's new series of CRS missions under a renewed contract with NASA. 
On 27 March 2020 SpaceX revealed the Dragon XL resupply spacecraft to carry pressurized and unpressurized cargo, experiments and other supplies to NASA's planned Lunar Gateway space station under a Gateway Logistics Services (GLS) contract.  NASA plans to use Dragon XL to transport sample collection materials, spacesuits and other supplies to be used on the Gateway and on the surface of the Moon. Dragon XL will launch on the Falcon Heavy and will transport more than 5,000 kg (11,000 lb) to the Gateway. Dragon XL will stay at the Gateway for six to twelve months at a time, when research payloads inside and outside the cargo vessel could be operated remotely, even when crews are not present.  
Autonomous spaceport drone ships Edit
SpaceX routinely returns the first stage of Falcon 9 and Falcon Heavy rockets after orbital launches. The rocket flights and land to a predetermined landing site using only its own propulsion systems.  When propellent margins do not permit a return to launch site (RTLS), rockets return to floating landing platform in the ocean, called autonomous spaceport drone ships (ASDS). 
SpaceX also plans to introduce floating launch platforms. These are modified oil rigs to use in the 2020s to provide a sea launch option for their second-generation launch vehicle: the heavy-lift Starship system, consisting of the Super Heavy booster and Starship second stage. SpaceX has purchased two deepwater oil rigs and are refitting them to support Starship launches. 
SpaceX is developing a fully reusable super-heavy lift launch system known as Starship. The Starship system comprises a reusable first stage, called Super Heavy, and the reusable Starship second stage and space vehicle. The system is intended to supersede the company's existing launch vehicle hardware by the early 2020s.  
SpaceX initially envisioned a 12-meter-diameter ITS concept in 2016 which was solely aimed at Mars transit and other interplanetary uses. In 2017 SpaceX articulated a smaller 9-meter-diameter vehicle to replace all of SpaceX launch service provider capabilities — Earth-orbit, lunar-orbit, interplanetary missions, and potentially, even intercontinental passenger transport on Earth — but do so on a fully reusable set of vehicles with a markedly lower cost structure.  In 2018, the Starship system was redesigned to use stainless steel instead of carbon fiber construction, with the aims of improving performance while drastically decreasing cost. Private passenger Yusaku Maezawa has contracted to fly around the Moon in a Starship vehicle in 2023.  The company's long-term vision is the development of technology and resources suitable for human colonization on Mars.   
Starlink is an internet satellite constellation under development by SpaceX. The Internet service will use 4,425 cross-linked communications satellites in 1,100 km orbits. Owned and operated by SpaceX, the goal of the business is to increase profitability and cash flow, to allow SpaceX to build its Mars colony.  Development began in 2015, initial prototype test-flight satellites were launched on the SpaceX Paz satellite mission in 2017. In May 2019 SpaceX launched the first batch of 60 satellites aboard a Falcon 9.  By May 2021, SpaceX had launched 1737 Starlink satellites.  Initial test operation of the constellation began in late 2020. 
In March 2017 SpaceX filed with the Federal Communications Commission plans to field a constellation of an additional 7,518 V-band satellites in non-geosynchronous orbits to provide communications services.  In February 2019 SpaceX formed a sibling company, SpaceX Services, Inc., to license the manufacture and deployment of up to 1,000,000 fixed satellite Earth stations that will communicate with its Starlink system.  The Federal Communications Commission (FCC) awarded SpaceX with nearly US$900 million worth of federal subsidies to support rural broadband customers through the company's Starlink satellite internet network. SpaceX won subsidies to bring service to customers in 35 U.S. states. 
On May 15, 2021 SpaceX and Google collaborated  to provide data and cloud services for Starlink Enterprise customers.
The planned large number of Starlink satellites has been criticized by astronomers due to concerns over light pollution,    with the brightness of Starlink satellites in both optical and radio wavelengths interfering with scientific observations.  In response, SpaceX has implemented several upgrades to Starlink satellites aimed at reducing their brightness during operation.  The large number of satellites employed by Starlink also creates long-term dangers of space debris collisions resulting from placing thousands of satellites in orbit.  
Other projects Edit
In June 2015 SpaceX announced that they would sponsor a Hyperloop competition, and would build a 1.6 km (0.99 mi) long subscale test track near SpaceX's headquarters for the competitive events.   The company has held annual competitions since 2017.  
In collaboration with doctors and academic researchers, SpaceX invited all employees to participate in the creation of a COVID-19 antibody-testing program in 2020. As such 4300 employees volunteered to provide blood-samples resulting in a peer-reviewed scientific paper crediting eight SpaceX employees as coauthors and suggesting that a certain level of COVID-19 antibodies may provide lasting protection against the virus.  
SpaceX is headquartered in Hawthorne, California, which also serves as its primary manufacturing plant. The company operates a research and major operation in Redmond, Washington, owns a test site in Texas and operates three launch sites, with another under development. SpaceX also operates regional offices in Texas, Virginia, and Washington, D.C.  SpaceX was incorporated in the state of Delaware. 
Headquarters, manufacturing, and refurbishment facilities Edit
SpaceX Headquarters is located in the Los Angeles suburb of Hawthorne, California. The large three-story facility, originally built by Northrop Corporation to build Boeing 747 fuselages,  houses SpaceX's office space, mission control, and, Falcon 9 manufacturing facilities. 
The area has one of the largest concentrations of aerospace headquarters, facilities, and/or subsidiaries in the U.S., including Boeing/McDonnell Douglas main satellite building campuses, Aerospace Corp., Raytheon, NASA's Jet Propulsion Laboratory, United States Space Force's Space and Missile Systems Center at Los Angeles Air Force Base, Lockheed Martin, BAE Systems, Northrop Grumman, and AECOM, etc., with a large pool of aerospace engineers and recent college engineering graduates. 
SpaceX utilizes a high degree of vertical integration in the production of its rockets and rocket engines.  SpaceX builds its rocket engines, rocket stages, spacecraft, principal avionics and all software in-house in their Hawthorne facility, which is unusual for the aerospace industry. Nevertheless, SpaceX still has over 3,000 suppliers, with some 1,100 of those delivering to SpaceX nearly weekly. 
Development and test facilities Edit
SpaceX operates its first Rocket Development and Test Facility in McGregor, Texas. All SpaceX rocket engines are tested on rocket test stands, and low-altitude VTVL flight testing of the Falcon 9 Grasshopper v1.0 and F9R Dev1 test vehicles in 2013–2014 were carried out at McGregor. Testing of the much larger Starship prototypes is conducted in the SpaceX South Texas launch site near Brownsville, Texas. 
The company purchased the McGregor facilities from Beal Aerospace, where it refitted the largest test stand for Falcon 9 engine testing. SpaceX has made a number of improvements to the facility since purchase and has also extended the acreage by purchasing several pieces of adjacent farmland. The company built a half-acre concrete launch facility in 2012 to support the Grasshopper test flight program.  As of October 2012 [update] , the McGregor facility had seven test stands that are operated "18 hours a day, six days a week"  and is building more test stands because production is ramping up and the company has a large manifest in the next several years.  In addition to routine testing, Dragon capsules (following recovery after an orbital mission), are shipped to McGregor for de-fueling, cleanup, and refurbishment for reuse in future missions. 
Launch facilities Edit
SpaceX currently operates three orbital launch sites, at Cape Canaveral Space Force Station, Vandenberg Space Force Base, and Kennedy Space Center, and is under construction on a fourth in Brownsville, Texas. SpaceX has indicated that they see a niche for each of the four orbital facilities and that they have sufficient launch business to fill each pad.  The Vandenberg launch site enables highly inclined orbits (66–145°), while Cape Canaveral enables orbits of medium inclination (28.5–51.6°).  Before it was retired, all Falcon 1 launches took place at the Ronald Reagan Ballistic Missile Defense Test Site on Omelek Island. 
Cape Canaveral Space Force Station Edit
In April 2007 the USAF approved the use of Cape Canaveral Space Launch Complex 40 (SLC-40) by SpaceX.  The site has been used from 2010 for Falcon 9 launches, mainly to low Earth and geostationary orbits. SLC-40 is not capable of supporting Falcon Heavy launches. As part of SpaceX's booster reusability program, the former Launch Complex 13 at Cape Canaveral, now renamed Landing Zone 1, has since 2015 been designated for use for Falcon 9 first-stage booster landings. 
Vandenberg Space Force Base Edit
Vandenberg Space Launch Complex 4 (SLC-4E) leased in 2011, is used for payloads to polar orbits. The Vandenberg site can launch both Falcon 9 and Falcon Heavy,  but cannot launch to low inclination orbits. The neighboring SLC-4W has been converted to Landing Zone 4 since 2015, where SpaceX has successfully landed three Falcon 9 first-stage boosters, the first in October 2018. 
Kennedy Space Center Edit
On 14 April 2014, SpaceX signed a 20-year lease for Launch Complex 39A.  The pad was subsequently modified to support Falcon 9 and Falcon Heavy launches. SpaceX launched its first crewed mission to the ISS from Launch Pad 39A on 30 May 2020. 
Boca Chica, Texas Edit
SpaceX manufactures and flies Starship test vehicles from a facility at Boca Chica, Texas, with future plans to conduct orbital Starship flights in 2021.  SpaceX first publicly announced plans for a launch facility near Brownsville, Texas in August 2014.   The Federal Aviation Administration (FAA) issued the permit in July 2014.  SpaceX broke ground on the new launch facility in 2014 with construction ramping up in the latter half of 2015,  with the first suborbital launches from the facility in 2019. 
Satellite manufacturing facility Edit
In January 2015 SpaceX announced it would be entering the satellite production business and global satellite internet business. The first satellite facility is a 30,000 sq ft (2,800 m 2 ) office building located in Redmond, Washington. As of January 2017, a second facility in Redmond was acquired with 40,625 sq ft (3,774.2 m 2 ) and has become a research and development laboratory for the satellites.  In July 2016, SpaceX acquired an additional 8,000 sq ft (740 m 2 ) creative space in Irvine, California (Orange County) to focus on satellite communications.  
SpaceX won demonstration and actual supply contracts from NASA for the International Space Station (ISS) with technology the company developed. SpaceX is also certified for U.S. military launches of Evolved Expendable Launch Vehicle-class (EELV) payloads. With approximately 30 missions on the manifest for 2018 alone, SpaceX represents over US$12 billion under contract. 
In 2006 NASA announced that SpaceX had won a NASA Commercial Orbital Transportation Services (COTS) Phase 1 contract to demonstrate cargo delivery to the International Space Station (ISS), with a possible contract option for crew transport.  Through this contract, designed by NASA to provide "seed money" through Space Act Agreements for developing new capabilities, NASA paid SpaceX US$396 million to develop the cargo configuration of the Dragon spacecraft, while SpaceX self-invested more than US$500 million to develop the Falcon 9 launch vehicle.  These Space Act Agreements have been shown to have saved NASA millions of dollars in development costs, making rocket development
4–10 times cheaper than if produced by NASA alone. 
In December 2010 the launch of the SpaceX COTS Demo Flight 1 mission, SpaceX became the first private company to successfully launch, orbit and recover a spacecraft.  Dragon successfully berthed with the ISS during SpaceX COTS Demo Flight 2 in May 2012, a first for a private spacecraft. 
Commercial cargo Edit
Commercial Resupply Services (CRS) are a series of contracts awarded by NASA from 2008 to 2016 for delivery of cargo and supplies to the ISS on commercially operated spacecraft. The first CRS contracts were signed in 2008 and awarded US$1.6 billion to SpaceX for 12 cargo transport missions, covering deliveries to 2016.  SpaceX CRS-1, the first of the 12 planned resupply missions, launched in October 2012, achieved orbit, berthed and remained on station for 20 days, before re-entering the atmosphere and splashing down in the Pacific Ocean.  CRS missions have flown approximately twice a year to the ISS since then. In 2015, NASA extended the Phase 1 contracts by ordering an additional three resupply flights from SpaceX, and then extended the contract further for a total of twenty cargo missions to the ISS.    The final Dragon 1 mission, SpaceX CRS-20, departed the ISS in April 2020, and Dragon was subsequently retired from service. A second phase of contracts was awarded in January 2016 with SpaceX as one of the awardees. SpaceX will fly up to nine additional CRS flights with the upgraded Dragon 2 spacecraft.  
In March 2020 NASA contracted SpaceX to develop the Dragon XL spacecraft to send supplies to the Lunar Gateway space station. Dragon XL will be launched on a Falcon Heavy. 
Commercial crew Edit
SpaceX is responsible for transportation of NASA astronauts to and from the ISS. The NASA contracts started as part of the Commercial Crew Development (CCDev) program, aimed at developing commercially operated spacecraft capable of delivering astronauts to the ISS. The first contract was awarded to SpaceX in 2011,   followed by another in 2012 to continue development and testing of its Dragon 2 spacecraft. 
In September 2014 NASA chose SpaceX and Boeing as the two companies that would be funded to develop systems to transport U.S. crews to and from the ISS.  SpaceX won US$2.6 billion to complete and certify Dragon 2 by the year 2017. The contracts include at least one crewed flight test with at least one NASA astronaut aboard. Once Crew Dragon achieves NASA certification, the contract requires SpaceX to conduct at least two, and as many as six, crewed missions to the space station.  SpaceX completed the first key flight test of its Crew Dragon spacecraft, a Pad Abort Test, in May 2015. 
In early 2017 SpaceX was awarded all six missions to the ISS from NASA.  In early 2019 SpaceX successfully conducted a full uncrewed test flight of Crew Dragon, which docked to the ISS and then splashed down in the Atlantic Ocean.  In January 2020, SpaceX conducted an in-flight abort test, the last test flight before flying crew, in which the Dragon spacecraft fired its launch escape engines in a simulated abort scenario. 
On 30 May 2020 the Crew Dragon Demo-2 mission was launched to the International Space Station with NASA astronauts Bob Behnken and Doug Hurley, the first time a crewed vehicle had launched from the U.S. since 2011, and the first commercial crewed launch to the ISS.  The Crew-1 mission was successfully launched to the International Space Station on 16 November 2020, with NASA astronauts Michael Hopkins, Victor Glover and Shannon Walker along with JAXA astronaut Soichi Noguchi,  all members of the Expedition 64 crew.  On 23 April 2021, Crew-2 was launched to the International Space Station with NASA astronauts Shane Kimbrough and K. Megan McArthur, JAXA astronaut Akihiko Hoshide, and ESA astronaut Thomas Pesquet.  The Crew-2 mission successfully docked on 24 April 2021. 
National defense Edit
In 2005 SpaceX announced that it had been awarded an Indefinite Delivery/Indefinite Quantity (IDIQ) contract, allowing the United States Air Force to purchase up to US$100 million worth of launches from the company.  In April 2008, NASA announced that it had awarded an IDIQ Launch Services contract to SpaceX for up to US$1 billion, depending on the number of missions awarded. The contract covers launch services ordered by June 2010, for launches through December 2012.  Musk stated in the same 2008 announcement that SpaceX has sold 14 contracts for flights on the various Falcon vehicles.  In December 2012, SpaceX announced its first two launch contracts with the United States Department of Defense (DoD). The United States Air Force Space and Missile Systems Center awarded SpaceX two EELV-class missions: Deep Space Climate Observatory (DSCOVR) and Space Test Program 2 (STP-2). DSCOVR was launched on a Falcon 9 launch vehicle in 2015, while STP-2 was launched on a Falcon Heavy on 25 June 2019. 
In May 2015 the United States Air Force announced that the Falcon 9 v1.1 was certified for National Security Space Launch (NSSL), which allows SpaceX to contract launch services to the Air Force for any payloads classified under national security.  This broke the monopoly held since 2006 by United Launch Alliance (ULA) over the U.S. Air Force launches of classified payloads.  In April 2016 the U.S. Air Force awarded the first such national security launch to SpaceX to launch the 2nd GPS 3 satellite for US$82.7 million.  This was approximately 40% less than the estimated cost for similar previous missions.  SpaceX also launched the 3rd GPS 3 launch on 20 June 2020.  In March 2018 SpaceX secured an additional US$290 million contract from the U.S. Air Force to launch another three GPS III satellites. 
In 2016 the U.S. National Reconnaissance Office (NRO) purchased launches from SpaceX, with the first taking place on 1 May 2017.  In February 2019, SpaceX secured a US$297 million contract from the U.S. Air Force to launch another three national security missions, all slated to launch no earlier than FY 2021. 
On 7 August 2020 the U.S. Space Force awarded its National Security Space Launch (NSSL) contracts for the following 5–7 years. SpaceX won a contract for US$316 million for one launch. In addition, SpaceX will handle 40% of the U.S. military's satellite launch requirements over the period. 
Space tourism Edit
In February 2020 Space Adventures announced plans to fly private citizens into orbit on Crew Dragon in late 2021 or 2022. The company would launch a Crew Dragon with up to four paying tourists on board, and spend up to five days in a low Earth orbit above the orbit of the International Space Station. 
SpaceX's low launch prices, especially for communication satellites flying to geostationary transfer orbit (GTO), have resulted in market pressure on its competitors to lower their own prices.  Prior to 2013, the openly competed comsat launch market had been dominated by Arianespace (flying the Ariane 5) and International Launch Services (flying the Proton).  With a published price of US$56.5 million per launch to low Earth orbit, Falcon 9 rockets were the cheapest in the industry.  European satellite operators are pushing the European Space Agency (ESA) to reduce launch prices of the Ariane 5 and the future Ariane 6 rockets as a result of competition from SpaceX.  In 2014 no commercial launches were booked to fly on the Russian Proton rocket. 
SpaceX also put an end to the United Launch Alliance (ULA) monopoly of U.S. military payloads when it began to compete for national security launches. In 2015, anticipating a slump in domestic, military, and spy launches, ULA stated that it would go out of business unless it won commercial satellite launch orders.  To that end, ULA announced a major restructuring of processes and workforce in order to decrease launch costs by half.  
Congressional testimony by SpaceX in 2017 suggested that the NASA Space Act Agreement process of "setting only a high-level requirement for cargo transport to the space station [while] leaving the details to industry" had allowed SpaceX to design and develop the Falcon 9 rocket on its own at a substantially lower cost. According to NASA's own independently verified numbers, SpaceX's total development cost for both the Falcon 1 and Falcon 9 rockets was estimated at approximately US$390 million. In 2011 NASA estimated that it would have cost the agency about US$4 billion to develop a rocket like the Falcon 9 booster based upon NASA's traditional contracting processes, about ten times more. 
In May 2020, NASA administrator Jim Bridenstine remarked that thanks to NASA's investments into SpaceX, the United States has 70% of the commercial launch market, a major improvement since 2012 when there were no commercial launches from the country.

The hepatitis B vaccine is the mainstay of hepatitis B prevention. WHO recommends that all infants receive the hepatitis B vaccine as soon as possible after birth, preferably within 24 hours &ndash followed by two or three doses of hepatitis B vaccine at least four weeks apart to complete the series. Timely birth dose is an effective measure to reduce transmission from mother-to-child.
According to latest WHO estimates, the proportion of children under five years of age chronically infected with HBV dropped to just under 1% in 2019 down from around 5% in the pre-vaccine era ranging from the 1980s to the early 2000s.
This marks the achievement of one of the milestone targets to eliminate viral hepatitis in the Sustainable Development Goals ─ to reach under 1% prevalence of HBV infections in children under five years of age by 2020.
In 2019, coverage of 3 doses of the vaccine reached 85% worldwide compared to around 30% in 2000. However, coverage of the hepatitis B vaccine birth dose remains uneven. Global coverage of the HBV birth dose, for example, is 43%, while coverage in the WHO African Region is only 6%. .
The complete vaccine series induces protective antibody levels in more than 95% of infants, children and young adults. Protection lasts at least 20 years and is probably lifelong. Thus, WHO does not recommend booster vaccinations for persons who have completed the 3-dose vaccination schedule.
All children and adolescents younger than 18 years and not previously vaccinated should receive the vaccine if they live in countries where there is low or intermediate endemicity. In those settings it is possible that more people in high-risk groups may acquire the infection and they should also be vaccinated. This includes:
- people who frequently require blood or blood products, dialysis patients and recipients of solid organ transplantations
- people in prisons
- people who inject drugs
- household and sexual contacts of people with chronic HBV infection
- people with multiple sexual partners
- healthcare workers and others who may be exposed to blood and blood products through their work and
- travellers who have not completed their HBV series, who should be offered the vaccine before leaving for endemic areas.
The vaccine has an excellent record of safety and effectiveness and the proportion of children under five years of age chronically infected with HBV dropped to just under 1% in 2019 down from around 5% in the pre-vaccine era ranging from the 1980s to the early 2000s.
In addition to infant vaccination, including a timely birth dose, WHO recommends the use of antiviral prophylaxis for the prevention of hepatitis B transmission from mother-to-child. Pregnant women with high levels of HBV DNA (viral load) and/or the presence of HBeAG have an elevated risk of transmitting the virus to their child, even among infants who receive the timely birth dose and the complete hepatitis B vaccine series. As such, pregnant women with high HBV DNA levels may be eligible for antiviral prophylaxis during pregnancy to prevent perinatal HBV infection and protect their infants from contracting the disease.
In addition to infant vaccination and prevention of mother-to-child-transmission, implementation of blood safety strategies, including quality-assured screening of all donated blood and blood components used for transfusion, can prevent transmission of HBV. Worldwide, in 2013, 97% of blood donations were screened and quality assured, but gaps persist. Safe injection practices, eliminating unnecessary and unsafe injections, can be effective strategies to protect against HBV transmission. Unsafe injections decreased from 39% in 2000 to 5% in 2010 worldwide. Furthermore, safer sex practices, including minimizing the number of partners and using barrier protective measures (condoms), also protect against transmission.
Where does March come from?
The first records of the word March as the name of a month come from before 1050. It comes from the Latin Mārtius mēnsis, meaning “the month of Mars,” referring to the Roman god of war. The months of January and May are also named after Roman deities.
The ancient Roman calendar originally began with the month we call March—March 1 was the first day of the year. Eventually, two additional months—what we now call January and February—were added so that the months would fall during the same seasons each year.
In ancient Rome, March marked the start of the military campaign season. However, the word march in the sense of walking in a military formation or in some other purposeful way is not actually related to the name of the month. The word march in the walking sense comes from the Old French marchier, “to tread,” possibly from the Frankish markōn, meaning “to mark or pace”—it’s not based on or related to Mars.
In astrology, the sign Pisces applies to those born between February 19 and March 20. The sign Aries applies to those born between March 21 and April 19.

What our visitors are saying about their experience
I want to thank the staff at the History Center for my daughter’s experience this summer [at camp]. Every staff member has been kind, talented and prepared – and helped nurture my daughter’s love of invention and creation. She deeply enjoyed the program. Thank you!Ximena Cordova Palma
I just have to tell you what a spectacular time our classes had today! The kids talked about it all afternoon, and all of our teachers raved about it! How early is too early to book for next year?Teacher Judy Lindquist, Andover Elementary School
The exhibits were interesting and well put together. I particularly enjoyed all the information about Florida’s citrus industry. Exhibits focusing on tourism were a close second favorite. Staff was helpful, and we enjoyed the optional audio tour.Halee Pearl
Great local museum! Took our daughter when she was 3 and she loved it. She asked to go back and at 5 she loved it even more! If you live in central Florida, or are visiting, you really need to check it out!Joanna Bond
