Space ProbesSpace Probes

Space probes are sent into space to gather information and pictures about other planets and our solar system. In 1976 NASA sent 2 Viking spacecraft to photograph and gather data about Mars. Robots called Pathfinder and Sojourner landed on Mars in 1997. Today the Hubble space telescope is traveling through our solar system sending information back to Earth.
