Mars Airship

This submittal is for a mobile rigid airship Mars base. For the 2014 NASA Mars base challenge.

It is assumed that a manned mars mission would run 5-10 years, and that the range of any rovers, etc in a stationary base would be limited to a few hundred kilometers. With a mobile base, any site on Mars can be studied.

The base survivability will be improved by being nomadic, whenever a surface exploration is not underway the base can be in motion to keep up with the sunlight or avoid incleme
