SLS and Orion gets people to the moon and back
Starship will just be the lander
I guess you fire an empty starship on a super heavy booster at the moon then meet it there with an SLS/Orion
Not really sure why they picked it though, it seems the most unlandery or the proposed Landers, for a start you need a huge ladder to get in and out?
Thank you for that

Misunderstood the job of Orion.
Does seem to be over the top option now I see what Starship is doing, as you say!
