The First SLS Launch Might be Delayed. Again.

The director of NASA’s Marshall Space Flight Center said March 5 that the agency is “reassessing” the 2020 launch date for the first flight of its Space Launch System, suggesting that the mission may face further delays.

During a question-and-answer session at a Space Transportation Association luncheon here, Jody Singer said the launch readiness date for Exploration Mission (EM) 1 is still in 2020, but did not give a more precise estimate of the date even as NASA reviews possible changes to it.

“We do know that we are reassessing those dates to see if that date will work, based on making sure we have the vehicle ready, and ready to go fly safely,” she said. “We are assessing that date. Our launch readiness date is still 2020, and we’re doing everything within our power to make sure that we support that.”

Singer didn’t identify the specific issues with EM-1 that prompted the reassessment, but NASA officials have previously said that the core stage of the SLS, along with the European-built service module for the Orion spacecraft that SLS will launch, were the items on the critical path for the mission.


Lockheed is ready to mate the first Orion capsule to its European made Service Module.
