The Commercial Crew Program was first announced in December 2009. The objectives of the program set out by NASA was to stimulate the commercial space industry; facilitate commercial demonstration of crew transportation abilities; and achieve safer, more reliable, more cost-effective access to low-Earth orbit. Following the finale of the Space Shuttle Program in 2011, the program became even more significant as a gap appeared where no human spaceflight would launch from American soil for several years. The Competition Crew Dragon is the second version of the Dragon spacecraft. First revealed in May 2014, the spacecraft will be human-rated, performing crew transport between Earth and the ISS as part of the Commercial Crew Program. The spacecraft will fly atop a Falcon 9 rocket from Cape Canaveral. Up to seven astronauts will be able to ride aboard what Elon Musk calls a 21st Century space vehicle. The launch pad abort test of the Crew Dragon occurred on May 6 2015. This tested the spacecraft’s ability to quickly leave a rocket disaster and therefore keep the crew alive. The Crew Dragon could make its first flight as early as late 2016, where an unmanned test flight to the ISS would occur. However, this date is not set in stone. Similarly, if all goes to plan the first manned mission of the spacecraft could occur as soon as late 2017. Boeing’s CST-100 Starliner The Boeing Crew Space Transportation system will also be transporting crew to the International Space Station from 2017. The space capsule can transport up to seven passengers, or a mix of crew and cargo, to low-Earth orbit. The vehicle will have flight compatibility with rockets Atlas V, Delta IV, Falcon 9 and the planned Vulcan rocket announced in 2015. The vehicle will have the ability to stay in orbit for up to seven months, and could be reused up to ten times.
Unlike SpaceX, Boeing are leaving their pad abort test until just months before the debut launch. Currently scheduled for February 2017, the capsule will be expected to prove that it can escape a catastrophic issue with the rocket. If successful, an unscrewed test mission will launch to the ISS in April 2017 and a crewed version in July. However, these dates are optimistic and are likely to change.
