Document Summary
A flyby mission flies by a planet just once. Cheaper than other missions but have less time to gather data. More time to gather data but cannot obtain very detailed information about world"s surface. Spacecraft designed to blast off other world and return to earth. Apollo and luna missions to the moon (1969 1976) Cassini/huygens mission contains both an orbiter (cassini) and a lander (huygens) Really a mistake in translation canals instead of channels. So the media caught hold of this and blew it up. Proved to be optical illusions but supports of the artificial construction camp like percival lowell used this to try to push proof of life on. Even though the canals were widely disproved the idea of life on mars was cemented in people"s mind. Amount of cratering differs greatly across surface. Olympus mons is largest volcano in solar system 40 km tall. System of valleys known as valles marineris thought to originate from tectonics.
