It's now been 20 years since NASA and the Jet Propulsion Laboratory sent surveyors to our neighboring planet, Mars. This "Mars Global Surveyor" (MGS) mission plans to send a satellite to Mars, which can build a comprehensive set of data to aid future missions. As you may already know, the sister mission to MGS, the Mars Pathfinder Mission, has already succeeded in landing on Mars on July 4th 1997. If everything goes well, the MGS is planned to arrive near Mars in September, carrying scientific instruments capable of obtaining data regarding Mars' surface features, atmosphere and magnetic properties, and should complete the mapping of Mars in January 2000.

Below are the various pages related to the MGS, represented by a graphical button followed by some descriptions. If you are using the frames version of this page, you can also navigate with the graphical menu on the left. We invite you to take up the challenge of our quiz after reading some pages, and we hope you would find extra fun in a real-time chat room with people all around the world, or simply exchange ideas and opinions through the message board. Any comment or suggestions about this site is most welcomed, and please drop us an e-mail if you wish.
