Bridenstine reckons the agency should try sticking to its dates

Fresh from a budget that has deferred the future of NASA's mega-rocket, the Space Launch System (SLS), the agency's own administrator has hinted that the present is looking iffy as well.

In a hearing yesterday, NASA administrator Jim Bridenstine admitted the agency had realised last week what many observers have suspected for some time: not only was the SLS not going to get off the ground in 2019, the not-later-than June 2020 date would probably be missed as well.

We need to consider all options to meet the Exploration Mission-1 target launch date of June 2020, including launching on commercial rockets.

NASA has a rich history in missing launch dates, although to be fair to the agency, changes in the policies of US administration and inconsistent funding have played their part.
