• Resumen

  • Focuses on the robots designed by the Jet Propulsion Laboratory in Pasadena Calif. that were used in space exploration. The many probes the Jet Propulsion Laboratory had prowling the solar system this year greatly advanced our knowledge of the planets. In January twin Mars rovers Spirit and Opportunity touched down on opposite sides of-the Red Planet, beaming images that provide the first indisputable proof that seas once existed on Mars and raising the odds of uncovering fossils or even life. At the same time, the Stardust spacecraft began its return to Earth after scooping up comet samples to shed light on the icy wanderers. In June the Cassini spacecraft arrived at Saturn successfully. So far Cassini has found two new moons there, and scientists hope that what the mission can tell them about Saturn's rings will also extend understanding of the disk of gas and dust that surrounded the early sun.
