Space has reported that in 2016, NASA first planned to launch the Orion-SLS in 2018 without any crew on the board. Earlier this year, Trump Administration has sent a transition team to approach NASA for an internal evaluation to check the possibility of sending a crew inside the Orion capsule inside SLS. Acting administrator of NASA, Robert Lightfoot said at a news conference,“ based on the results of this internal evaluation, a crewed flight would be technically feasible, but the agency will proceed with its initial plan to make the rocket's first flight uncrewed”.

NASA also announced that the next mission(EM-2) will be scheduled on 2021 and it would be a crewed flight. Now, Lightfoot and NASA officials are concentrating about the schedule of EM-1 as it is already delayed. NASA’s Michoud Assembly Facility in New Orleans was seriously damaged by the tornado where Orion-SLS was planned to be assembled with the jet propulsion system and the Orion capsule. After lots of discussion NASA team and White House have decided to launch the Orion-SLS in2019. However, the exact date of launch is still unknown. Associate administrator for human exploration and operations for NASA, Bill Gerstenmaier said that delay of WM-1 Will also affect the launch date of Em-2.
