Preparing for the launch of the third US Navy Mobile User Objective System (MUOS) satellite, MUOS-3, on Tuesday aboard an Atlas V rocket from Cape Canaveral:
Gwynne Shotwell, president and chief operating officer of Space Exploration Technologies, or SpaceX, said her company’s upgraded Dragon V2 ferry craft should be ready for an initial unpiloted flight to the space station in late 2016 with the first crewed flight, likely carrying a SpaceX test pilot and a NASA astronaut, in early 2017.
John Elbon, vice president and general manager of Boeing Space Exploration, said his company’s CST-100 spacecraft is expected to be ready for an uncrewed test flight in April 2017, followed by a crewed flight, with a Boeing pilot and a NASA astronaut, in the July 2017 timeframe.
Both companies must complete the crewed and uncrewed test flights before NASA certification, which will pave the way for the start of operational crew rotation and cargo delivery flights to the International Space Station later in 2017. Until then, NASA will continue to rely on Russia’s Soyuz spacecraft to carry U.S. and partner crew members to and from the lab complex.
