Nozebleed

Ok. i know nothing about space!! i just watch sci-fi...there are loads of threads regarding mars of late..and it got me thinking

man has been to the moon..why have we not in a controlled environment of some kind. tried to grow something like grass on the moon.

i should have posted this in afterhours. :pac:

For grass to grow you need a number of things.

1. A pressurised atmosphere at the correct pressure
2. The atmosphere must contain the correct mix of gases (carbon dioxide very important
3. Soil with the correct mineral mix
4. Sunlight
5. Water

3 wouldn't be a huge issue as the soil could be transported from earth. 1 and 2 are the biggest issues. The Moon's gravity isn't large enough for the moon to hold onto an atmosphere. The atmosphere would simply be lost to space.

If maybe possible if grown in a sealed greenhouse where the correct mixture of air is present though.

Feck growing grass on the moon! what about them ever mining helium-3 from it. The will need a moon base though. Pity they couldn't land the ISS on the moon, and go from there.

They could, but it wouldn't be in one piece anymore.

You'd probably need gravity too, going back to my leaving cert geography, geotropism depends on gravity, this is how the seed knows which way to send the shoots.

The moon has gravity

Yes, there is, but is too weak to let the growing grass;)

terraforming the moon.....

......as they say - possible, but not probable!

You could use simple fission reactors as a power source, but you'd need somewhere to store the waste. Given the dark side would be of no practical use, that would be the logical spot to store and stockpile the radioactive material.....

....I mean, what could possibly go wrong!
