funny, since Phobos is "one of the darkest objects in the solar system"!

In principle, a person could run and jump off of this tiny moon. I think the escape velocity is about 3m/s.

Unprotected you would die first. It would probably be easier to just jump straight.

Very interesting Ivan; however, the escape velocity of Phobos is about 11.5 m/sec, so you couldn't jump straight up. I can't run that fast but a good sprinter could and thus, running off an appropriately positioned cliff, he could launch himself into space. That's about 26 mph; so I could probaly ride a bicycle into space;....well, at least I could throw baseballs into space.

It is quite amazing to realize that I could stand on a Martian moon and I could terrorize the Martian surface by pelting it with appropriately directed baseballs as often as I wish. It would be interesting to figure the enourmous increase in energy by which my feeble baseballs would decsimate the surface of Mars. [8)](Assuming I could keep my baseballs from burning up in the Martian atmosphere). Or I could take a free ride on my bicycle in in a chosen direction such that I will end up on the surface of Mars (with quite an impact I might add)!![g)]

It makes me think that Phobos may one day be a very stategic place if Mars ever becomes inhabited.
Just a thought.[;)]

P.S. Thanks Phobos for the appetizing images.

How about Deimos? I remember 3m/s for something. Still, what a concept eh?

Kerrie - - yep, likely just a captured asteroid

Creator - - (re: biking to Mars) Just use airbags like NASA does!

He, He; good point; maybe I'll give it a try.[a)]
