Cycling down Olympus Mons?

Postby cheaterkiller » Wed Jan 30, 2013 20:52 pm

How long would it take the average MTBer to do this? (ignoring the deficit of breathable air ofcourse).

Its not very steep for the first 100 km and 17 km of vertical descent till you hit the 5km high escarpment at the base. Not sure how fast you would go in a vacuum but you would probably fly a long way when you went off the edge because of the low gravity.

There's no air but there's still an atmosphere, you're not in a vacuum. Mind you it's still a lot lower than earth (IIRC the atmospheric pressure at the base of olympus mons is lower than at the top of Everest)

The low gravity'll mess up your rebound settings :lol:

Also there's a high risk of your holiday being disrupted if those bloomin Reds knock down the space elevator again

If wikipedia is to be believed the atmospheric pressure at the summit is 72 pascal so it might as well be a vacuum. The pressure at the base is 600 pascal. To give you some idea the Earths atmospheric pressure at sea level is 100,000 pascal give or take a 1,000. You will need SPDs as flats will probably damage your suit.

Mars has 38% of the earths gravity

Tyre pressures (guage) will need to 38% of those on earth.

Fork/shock pressures will logically be 38% of those required on earth, damper 'settings' need to be adjusted accordingly.
