In September 1997, while Pathfinder and Sojourner were exploring the surface of Mars, another probe was placed in orbit around the planet. Mars Global Surveyor will make a general portrait of Mars. It will observe climatic changes on the surface over a complete Martian year, which is equivalent to two Earth years. | |
