Nasa are funding a chunk of the research because from what Einar
(project leader)said there actually isn't that much research material
on the that part of the atmosphere. Secondly if you don't have the
data how can you design any flight vehicle to operate efficiently
in that enviroment.

There's not really much to explo Stall speed is very high, so you need
a huge runway to take off and land, and there will be some implications
concerning the radius of turns. The smaller gravitation has some influece,
too, but I can't tell off hand which.
