Here's a space shuttle I modeled, the Ascraeus, named after Ascraeus Mons, one of the prince volcanoes of the 4 major volcanos on Mars... Ascraeus Mons, Pavonis Mons, Arsia Mons, and the king, Olympus Mons, the biggest volcano in the solar system. Bye the way, that's Mars in the background. And if you're really intersted, that huge scar running the length of the planet is Valles Marineris, an enormous canyon which would span the United States if it were on the Earth. It is 100 miles wide and 10 miles deep. The grand canyon? PAH!
