SLS has been to the moon and back. Starship hasn't yet made it to orbit.

SLS has been around the moon and back; that mission was equivalent to an unmanned Apollo VIII. Going around the moon is much easier than landing on it and coming back.

  • Sure. And not-quite-getting-into-orbit is easier -- significantly easier -- than going around the moon.

    What's your point, really, aside from nitpicking, when "orbiting the moon" is a perfectly reasonable interpretation of the statement "been to the moon and back"?

    • I think the difference between the US lunar exploration program and the Soviet one qualifies as more than mere nitpicking.

Starship has made orbit several times.

  • To be pedantic, Starship has made orbital velocity several times. It didn't circularize enough to be a full orbit. A full orbit would have been irresponsible. Blue Origin has left a massive trail of space junk from their last test mission because they went for an ambitious orbit rather than one that would passively deorbit immediately.

  • Kinda. They demonstrated orbital delta-v, but the perigee was always low enough to guarantee re-enter atmosphere after just half an orbit from launch, because of SpaceX's unreadiness to confidently perform a controlled de-orbit otherwise.
