The picture above compares the sizes of the landers. On the left is the original LM from the 60’s. Next are the two that nasa didn’t pick. SS, on the right, dwarfs them all.
I don’t think the public at large yet realizes how much capability we will have once we get to the moon. I have always been somewhat of a space nut, and I understand that the average person doesn’t care, but this is going to be a game changer for not just the United States but the world.
We will be able to do things at the moon that will be straight out of sci fi. A landed SS could immediately be turned into a permanent base. Other SS landed in close proximity could bring supplies. We could mine the moon. Do real exploration.
The longest stay on the moon was what nasa called the j missions. They were about 3 days, and they traveled a few km from the lm. Apollo 11 had an EVA that lasted only a few hours.
