How well does it work in a zero gravity environment? Looking for a mower to take on a space mission (Mars 2022) Would mulching blades still work?

Not sure if this helps, but it worked perfectly for me on The Moon. This does not however take Glock mags.

I think the Martian soil contains lots of iron. This would dull the blades prematurely. May want to consider custom titanium blades. Gravity shouldn’t be an issue on Mars. Good luck and God Speed!
