What a waste: NASA has chosen the four shuttle engines that will be used to launch SLS on its first mission in 2021.

All four engines were used multiple times on many shuttle missions. They will fly once on SLS, at a cost of many billions, and then end up destroyed when that giant rocket’s first stage falls into the ocean. Worse, no one has really defined what the goal of that first launch will be. It might merely be a test launch, with no humans on board.

To me, it would be wiser to put the engines into storage and wait until we have a new reusable capability that could take advantage of the reusable engineering of these engines. Throwing them away on a pork-barrel boondoggle like SLS seems so stupid.

    Hoping for intelligent managment from any USG agency is asking for a lot….from the White House on down, our govt keeps acting as though they have a blank check , and card blanche’….

    2021 is a long way away for a NASA plan. How long has it been since one of their projects has gotten much past the “Pretty Picture” stage?

    They are just doing this in hopes that it will make a first launch date a bit closer to Space X’s proposed manned flight date.

    Its all they have. They have no new engines on the table and these areal ready built tested and NASA approved.

    Well NASA did want to destroy and discredit reusable launchers to keep launch costs up – so it kind of fits policy.

    Frankly having the Orbiters grounded is bad enough but we’re lucky they didn’t scrap them!
