The
CST-100 Starliner is a spacecraft design under construction by
Boeing in collaboration with
Bigelow Aerospace as their entry for
NASA's
Commercial Crew Development (CCDev) program. Its primary mission is to transport crew to the
International Space Station, and to private space stations such as the proposed
Bigelow Aerospace Commercial Space Station.
It is similar to the Orion, a spacecraft being built for NASA by Lockheed Martin. The capsule has a diameter of 4.56 meters (15.0 ft), which is slightly larger than the Apollo command module and smaller than the Orion capsule. The Starliner is to support larger crews of up to seven people. The CST-100 is designed to be able to remain on-orbit for up to seven months and for reusability for up to ten missions. It is to be compatible with multiple launch vehicles, including the Atlas V, Delta IV, and Falcon 9, as well as the planned Vulcan. The initial launch vehicle would be the Atlas V.
On September 16, 2014, NASA selected the CST-100, along with SpaceX's Dragon V2, for the Commercial Crew Transportation Capability (CCtCap) program, with an award of $4.2 billion. The spacecraft is expected to fly to the International Space Station with an astronaut aboard by December 2017.
Sergei Konstantinovich Krikalyov (
Russian: Сергей Константинович Крикалёв, born August 27, 1958) is a
Russian cosmonaut and
mechanical engineer. As a prominent
rocket scientist, he has been veteran of six space flights and currently has spent more time in space than any other human being. He transliterates his name in English as
Sergei Krikalev.
On August 16, 2005 at 1:44 a.m. EDT he passed the record of 748 days held by Sergei Avdeyev. He now has spent a total of 803 days and 9 hours and 39 minutes in space.
Krikalev was born in Leningrad (now St. Petersburg), Russia. He enjoys swimming, skiing, cycling, aerobatic flying, and amateur radio operations, particularly from space (callsigns U5MIR and X75M1K).
On February 15, 2007, Krikalev was appointed Vice President of the S.P. Korolev Rocket and Space Corporation Energia (Russian: Ракетно-космическая корпорация "Энергия" им. С.П.Королева) in charge of manned space flights.
Krikalev was dubbed by many "the last Citizen of the USSR " as in 1991–1992 he spent 311 days, 20 hours and 1 minute aboard the Mir space station while, back on Earth, the Soviet Union collapsed. A fictional account of how Krikalev may have felt about this is described in the song "Casiopea", written by Cuban songwriter Silvio Rodríguez.
