The last time a spacecraft successfully touched down on the Martian surface was July 4, 1997. NASA's Mars Pathfinder then put a nascent Internet to work, flooding it with wonderful color photographs that the world could, for the first time, peruse without waiting for the next day's newspaper. Like the red planet and the birth of the Internet, the Pathfinder mission seems a world away right now. The photos, however, are as cool as ever. This Martian sunset created a red sky because dust in the thin atmosphere absorbs blue light, leaving the red to pass through, scientists say.
