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.
Alexey Arkhipovich Leonov (30 May 1934 – 11 October 2019) was a Soviet and Russian
cosmonaut,
Air Force major general, writer, and artist.
On March 18, 1965, he became the first human to conduct extravehicular activity (EVA), exiting the capsule during the Voskhod 2 mission for a 12-minute spacewalk. During the spacewalk, he encountered severe difficulties due to the design of his spacesuit.
Leonov had been tapped to be a commander for the Soviet crewed lunar programs, and would've commanded the first crewed Soyuz 7K-L1 Zond mission if it were ever cleared to proceed. He was selected as commander of Soyuz 11, the second planned (and first successful) mission to the Salyut 1 space station, but the entire crew was swapped out when crewmate Valeri Kubasov was suspected of contracting tuberculosis. This saved him from dying when Soyuz 11 de-pressurized during re-entry, killing the cosmonauts on-board.
Leonov was then selected as commander of Soyuz 19, the Soviet side of the Apollo–Soyuz Test Project, again with Kubasov. They would be joined by Apollo astronauts Tom Stafford, Vance Brand, and Deke Slayton, on the mission in July 1975.
Leonov would serve as "Chief Cosmonaut" from 1976 through 1982, and retired from the Soviet space program in 1991. He would spend time in the private sector in post-Soviet Russia, most notably at Alfa-Bank, until he retired for good in 2001. He has written several books about his space experience, including a joint biography with American astronaut David Scott in 2006.
