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

    mmmm I just want to put some bacon and chedder cheese in that moon and eat it

    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. (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)!!

    It makes me think that Phobos may one day be a very stategic place if Mars ever becomes inhabited.
    Just a thought.:wink:

    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.
