 | | But it took the space program, with its probes to and orbiters around the planets, to open up the other planetary bodies in the Solar System to a systematic examination. |
 | | Since then, we have many observations of our solar system neighbors, first with telescopes and, after the opening of the Space Age, with orbiting spacecraft, flyby, probe, and lander missions. |
 | | Here is a list of remote sensing methods using EM spectral measurements that have provided exceptional information about planetary surfaces, atmospheres, and, indirectly, interiors: * |
