Crewed Mars rover the following types of rovers: In human Mars missions, rovers are sometimes grouped under what have been called "mars surface elements".: Crewed Mars rover Crewed Mars rovers are vehicles for transporting people on the planet Mars, and have been conceptualized as part of human mission to that planet. Two types of crewed Mars rovers are pressurized and unpressurizedunpressurized designs may have open seating for a crew in Mars space suits, and another style has a pressurized interior for people to work without a space suit. Pressurized rovers have been envisioned for short trips from a Mars base, or they may
Moons of Uranus to be responsible for the heating that caused substantial endogenic activity on Miranda and Ariel. One piece of evidence for such a past resonance is Miranda's unusually high orbital inclination (4.34°) for a body so close to the planet. The largest Uranian moons may be internally differentiated, with rocky cores at their centers surrounded by ice mantles. Titania and Oberon may harbor liquid water oceans at the core/mantle boundary. The major moons of Uranus are airless bodies. For instance, Titania was shown to possess no atmosphere at a pressure larger than 10–20 nanobar. The path of the Sun in the
