SpaceX and Boeing continue to make steady progress towards the major flight tests under NASA’s Commercial Crew Program. At a NASA Advisory Council (NAC) meeting on Monday, the members were updated on the progress of each of the two providers. Overall, the updates were quite positive with most of the flight hardware nearing completion.The two companies must each execute two test flights to the International Space Station (ISS) in order to be certified to perform operational crew rotation missions.On the SpaceX side, the company will first execute an uncrewed test flight of the Crew Dragon spacecraft called Demonstration Mission 1 (DM-1) – currently scheduled for this coming November. It will then be followed by a crewed test flight designated Demonstration Mission 2 (DM-2). In between the two missions, SpaceX will also execute an in-flight abort test.In terms of Boeing, they will perform an uncrewed Orbital Flight Test (OFT) with the CST-100 Starliner followed by a Crewed Flight Test (CFT). A pad abort test will be also conducted between the two missions.
