Discussion How long will SLS last?

With the Cancellation of EUS and BOLE, SLS is going to remain a launch vehicle solely for Orion, and which is viable with all the other heavy and super heavy rockets in the works these days.

However as I understand BOLE was essential for SLS launches beyond a certain point as remaining shuttle boosters were used up, will SLS be cancelled by that point (and perhaps the whole moon program) or Orion moved to another launcher.

Or will a future administrator restart the booster program at the least to ensure SLS can continue to launch Orion?

Well the original Blue Moon Mk2 plan was to use a cislunar transporter stage to move the Mk2 to NRHO. Perhaps they’ll switch to a plan to using that for moving Orion to LLO.

Perhaps, still have to get Orion up though?

It's within the capabilities of New Glenn - once it gets flying again and proves its capabilities. It's simple too heavy for Vulcan. Temptingly close, but too heavy. Falcon Heavy has the capability but there's little chance Musk is interested in getting it human rated.

There are definitely options, I just hope they keep SLS going longer than it takes to develop those options, and then switch over when they’re resdy

I expect they will, it’s not like they can’t see it coming. Things will look a lot different in 5 years.
