We are assuming here that the two jets exert exactly the same force. If one is stronger than the other upon activation, then we have the interesting situation of a new linear motion arising, AND some net torque, even if small. Usually spacecraft jets are not supposed to do that. When operating correctly, in the same direction, the jets can put the spacecraft on a different trajectory. Troposphere The lower regions of a planetary atmosphere where convection keeps the gas mixed and maintains a steady increase of temperature with depth.
Most clouds are in the troposphere.
U Return to Main Index Uranus Uranus is tipped over so far that it actually rotates on its side. It is unique in this. The color of blue that is seen in the telescope is caused by the methane in the upper atmosphere which absorbs the red light. Only the blue escapes to reach our telescopes. Uranus, like the other Giant Planets , has rings, but they are very faint and cannot usually be seen from Earth unless with a large telescope.
