The name for a partner who is involved in a queerplatonic relationship, as in he's my zucchini.
Curiosity, a rover that's exploring Mars as of 2014, has a top ground speed of 1.5 inches per second, or about 0.1 mph. Curiosity landed on Mars on Aug. 5, 2012.
In order to get to Mars the spacecraft needs a speed of 32.82 km/s relative to the sun (assuming a Hohmann transfer) at Earth's orbital radius. Now the speed of the Earth relative to the sun is 29.78 km/s already.
