Flight 15P of
SpaceShipOne (X0) was the first privately funded
human spaceflight. It took place on June 21, 2004. It was the fourth powered test flight of the
Tier One program, the previous three test flights having reached much lower altitudes. The flight carried only its
pilot,
Mike Melvill, who thus became the first non-governmental
astronaut.
This flight was a full-altitude test. SpaceShipOne was dropped from its carrier aircraft, White Knight, at 14:50 UTC (7:50am PDT), at an altitude of 47,000 feet (14,000 m), and fired its on-board rocket for 76 seconds. It reached a peak altitude of 328,491 feet (100,124 m), becoming the first commercial manned spacecraft to cross the Kármán line. It landed safely at Mojave Air and Space Port, California, 15:14 UTC (8:14am PDT).
Flight 15P was a test flight to prepare Scaled Composites to compete for the Ansari X Prize, the prize for the first non-governmental reusable manned spacecraft. Scaled Composites would win the Ansari X Prize in October 2004 after two more successful flights.
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.
