Post by: [email protected] on 05/04/2021 03:43 pm

When on moon or Mars how will ingress egress for personnel and equipment be done on a vertical ship?

Great question!

The current plan for Lunar Star ship is sort of an elevator/crane type mechanism mounted on the side, next to the airlock.
Starting about at around 2:15, this animation does a pretty good job of showing this mechanism in action:

The National Team's proposed three-stage design had just a normal ladder, albeit longer than that of the Apollo LEM.

And then there are those designs that are not "vertical," namely, Dyenetics' ALPACA proposal and - from the first decade of the 2000s, ULA's DTAL proposal. Masten was later authorized to test a scaled-down version XEUS. These are all designed to have the airlock or door practically right next to the lunar surface.
