Dragon is a
spacecraft developed by
SpaceX. During its maiden flight in December 2010, Dragon became the first commercially built and operated spacecraft to be recovered successfully from orbit. On May 25, 2012, a cargo variant of Dragon
became the first commercial spacecraft to successfully
rendezvous with and be attached to the
International Space Station (ISS). SpaceX is contracted to deliver cargo to the ISS under
NASA's
Commercial Resupply Services program, and Dragon began regular cargo flights in October 2012.
The spacecraft is currently launched atop a Falcon 9 Full Thrust rocket. Earlier missions, through SpaceX CRS-2, used the original Falcon 9 rocket. Dragon has been launched on seven missions, with one, SpaceX CRS-7, suffering a launch failure.
Dragon was renewed for the second round of the Commercial Resupply Services in 2016. It is also the basis for the Dragon V2 manned spacecraft, which was selected under the CCDev program in 2014 to deliver astronauts to the ISS.
Sally Ride (May 26, 1951 – July 23, 2012) was an American
physicist and
astronaut.
Born in Los Angeles, she joined NASA in 1978 and became the first American woman in space in 1983. She remains the youngest American astronaut to have traveled to space, having done so at the age of 32. After flying twice on the Orbiter Challenger, she left NASA in 1987. She worked for two years at Stanford University's Center for International Security and Arms Control, then at the University of California, San Diego as a professor of physics, primarily researching nonlinear optics and Thomson scattering.
She served on the committees that investigated the Challenger and Columbia Space Shuttle disasters, the only person to participate on both.
Ride died following a 17-month-long battle with pancreatic cancer on July 23, 2012. Shortly before her death, she came out as a homosexual in a statement through her philanthropic enterprise, Sally Ride Science.
