Human Deep Space Exploration

First SLS/Orion Launch Slips to 2019, No Crew

Space Policy Online (5/12): After a two month assessment, NASA says it will not attempt to fly astronauts on the first joint test flight of the Space Launch System rocket and Orion crew capsule. An Exploration Mission-1 flight with two astronauts would not have been possible until 2020 and would cost an additional $600 million to $900 million. EM-1, even uncrewed, will slip from late 2018 into 2019. The launch of the uncrewed EM-1 will determine the date for EM-2, which will include astronauts launched on a journey around the moon and back to Earth.
