Sierra Space’s Dream Chaser took a step closer to its long-awaited first flight by powering up its systems in a key test.
Is there still a path to Vulcan flying a national security mission in 2023?
Sierra Space says it is making good progress on its first Dream Chaser spaceplane as the company looks ahead to versions of the vehicle that can carry crews and perform national security missions.
ULA said the delay in Dream Chaser’s first mission will not prevent Vulcan from getting certified on time for its first national security mission in 2022.
Sierra Nevada Corporation (SNC) says the first flight of its Dream Chaser spacecraft to the International Space Station is now planned for 2022 after development delays caused by the pandemic.
