WebThe exploration of the solar system has been carried out largely by robot spacecraft sent to the other planets. To escape Earth, these craft must achieve escape speed, the speed needed to move away from Earth forever, which is about 11 kilometers per second (about 25,000 miles per hour). WebThe two-way Doppler measurement was the only means for the ground operators to monitor the spacecraft motion during the landing period in real time. It corresponds to the spacecraft velocity relative to the asteroid along the Earth-asteroid line (i.e., Z HP axis).
