Less interesting that I thought.hoped, but still worth a quick read.

Lack of fuel is the problem

WWithout reading the link I’ll take a wild stab in the dark, or better yet, a SWAG, and say no.

There isn’t that much man made junk on the moon I’m thinking. Plus it is spread pretty thin. Thousands of km between each landing and test sites.

Ground Control to Major Tom
Ground Control to Major Tom
Take your protein pills
and put your helmet on

Ground Control to Major Tom
Commencing countdown,
engines on
Check ignition
and may God’s love be with you

Ten, Nine, Eight, Seven, Six, Five, Four, Three, Two, One, Liftoff

This is Ground Control
to Major Tom
You’ve really made the grade
And the papers want to know whose shirts you wear
Now it’s time to leave the capsule
if you dare

This is Major Tom to Ground Control
I’m stepping through the door
And I’m floating
in a most peculiar way
And the stars look very different today

For here
Am I sitting in a tin can
Far above the world
Planet Earth is blue
And there’s nothing I can do

Though I’m past
one hundred thousand miles
I’m feeling very still
And I think my spaceship knows which way to go
Tell my wife I love her very much
she knows

Ground Control to Major Tom
Your circuit’s dead,
there’s something wrong
Can you hear me, Major Tom?
Can you hear me, Major Tom?
Can you hear me, Major Tom?
Can you….

Here am I floating
round my tin can
Far above the Moon
Planet Earth is blue
And there’s nothing I can do.

If you want fuel on the moon, take hydrogen. There’s plenty of oxygen already there, most of it bound up in oxides but the oxygen can be liberated by heat from electricity plus the noonday Sun. The hydrogen weighs only a sixteenth of the oxygen. Burn the hydrogen with oxygen to get both energy to use and water to drink.

If you want shelter, build one out of rocks, there are plenty of rocks on the Moon.

There are heaps and heaps of communications equipment on the Moon. If batteries are dead then either clean the dust off the solar cells, or take out the electrodes are replace the electrolyte. You have water (see above) so can use that for electrolyte together with salt – in a really tough situation you can mix a little human blood with the water to get a usable electrolyte.

The biggest man-made objects on the Moon would be Saturn IV-B stages. Admittedly they hit hard, too hard to retain their oxygen and hydrogen reserves, but with a mass of 120 tons each there should be plenty of hardware left to make things from.

also there is no re-entry vehicle for when you get back. though i guess you could hope they would send up something to take you down…or orbit close to the ISS and transfer over.

There is no Lunar return trajectory that ends up in a LEO :)
