Artemis II plan (April, 2026)

At the moment, we just cannot.

We don't even have space suits that can operate on the moon. The stuff they use on the ISS is made to be used in a total vacuum only, not walking around in the dust and on sharp rocks. There are new suits in development, but nothing final as far as I know. I'm not sure if any are close to being finished, let alone tested and certified.

In theory you could put a Crew Dragon with a big trunk of supplies on a Falcon Heavy, which has the delta-V to go to the moon. But obviously that's pretty risky, once you go you're committed. When working in LEO you almost always have some kind of disaster recover scenario available where you abort and get back to earth asap. If you are underway to the moon, there is no turning back. The Crew Dragon has very limited mobility. But I think a trans-lunar injection and orbit around the moon would be possible, with a free return trajectory. So if going around the moon is good enough, that would be possible.

Still it would probably take 9-12 months to put such a mission together and it would be very risky indeed. And like I said, landing on the moon is a total no-go right now.

Just a civilian guess, but 2 or 3 Delta V or Falcon Heavy to put 1 payload into LEO with a command module and lander, then 1 booster with fuel. Short of using prototype lander, fabrication would take months at best. Then a Starship or SLS to get a crew, food, and water into orbit.

Responding because I am also curious about this.

It depends, do you need to return your representative, or can we leave him on the moon? Latter is easier. Maybe he can hitchhike back with the aliens.

If it's a one-way mission, it could be done with a Falcon heavy and a slapped-together lander sourced from NASA. Maybe even an old Gemini capsule or something from the Smithsonian.

Or you could send up a Falcon heavy with fuel payload, rendezvous with the ISS, pick up a 'naut, and steal a Soyuz, although I'm not sure if they can be configured to land on the moon

Nah, they should rush it

They need to consult with Wallace and Gromit

Republicans will cancel it, I guarantee it. Then they'll put their stamp on a new mission, put it all into SpaceX hands, and send Melon some more money.
