I was lucky to catch the launch live very early this morning, it was impressive to see. As I understand, they are using rebuilt & upgraded rocket engines leftover from the shuttle program.
Lucky man. YEs they are re- using old shuttle engines. Can they salvage the first stage and recycle the engines or is it one and done?
Boosters and the core will not be recovered.

Here's an article with info on the engines.
Good article. Thanks. Hope we have a lot old engines sitting around. Or are building new ones now.Boosters and the core will not be recovered.
Artemis I launch guide: What to expect
NASA's Space Launch System rocket is sending the Orion crew capsule to the Moon and back.
Seems like they have enough for five flights, then a flight with two old and two new. Then continued flights with all new engi.Here's an article with info on the engines.
Return to flight: NASA's Artemis I mission to launch using space shuttle-used parts
More than a decade after NASA landed its last space shuttle, major parts from all five of the retired winged orbiters are ready to launch again — this time on a mission to the moon. Components that flew on 83 space shuttle missions are now part of Artemis I.www.collectspace.com
Used. Read the article linked by SLUPSU. Some have flown many shuttle missions.
The Interim Cryogenic Propulsion Stage (ICPS - 2nd stage) was jettisoned into a heliocentric orbit, so it won't be coming back either.Boosters and the core will not be recovered.
Artemis I launch guide: What to expect
NASA's Space Launch System rocket is sending the Orion crew capsule to the Moon and back.
Artemis 2 (manned) will fly in 2024 and the boots on the moon mission (Artemis 3) will be in late 2025 or early-mid 2026. that's the word around the campfire. Depending on the results of Artemis 1, these dates could slip or be brought in. But, I wouldn't bet on the latter.
Outdated by what? Is there another rocket capable of launching a vehicle into lunar orbit?
So, the SLS was not outdated 6 years ago. SpaceX is developing a rocket for deep space, I do not how much that is going to cost. Space exploration is not cheap. We get technological advancements from space exploration, so IMO its money well spent. More useful than Spacebook, MyFace, or Tweeter.
What do you suggest for propellent? Once out of Earth's gravitational pull, perhaps ion propulsion like that used on the DAWN mission.
I don't know enough about propellent and oxidizers to say which is better, or what other alternatives there would be. Hopefully, Space X will be successful with Starship. I haven't seen much in the news lately about where they are in development and testing.
They are probably using hydrogen because of green weenie cry babies. H + O2 = water. Cleanest rocket fuel there is.
I think SpaceX is going to launch Starship from Texas, where they have a launch facility.
We reaped the R&D rewards from a years of a $ 20 trillion free market economy. The NASA can't name a technology they want. Throwing shit against the wall to see if anything good comes out is just ... shit.
I expected that weak response. That's your endeavor, not mine. But with my tax dollars.
So now you think that your tax dollars should only be spent on things that everyone agrees on? If that was the case, I would have some bad news for you Mr. Gov't Employee.
