Mars has two moons, Phobos and Deimos. Phobos orbits at 6000 km above the surface of Mars, closer than any other moon in the solar system, once every 7.66 hours. (Radius of Mars = 3389 km). You want to put an artificial satellite (the Mars Reconnaissance Orbiter in this case) into a circular orbit at a height of 300 km above the surface of Mars. This process, called orbital insertion, requires the orbiter to speed up or slow down to...
