Amazing stuff I've been following for the last five years, the Mars Exploration Rovers Spirit and Opportunity. I am one of the millions of awe-struck earthbound humans who marvel at the enormity of the achievement of these rovers and their exploration of Mars so far. Of the hundreds of engineers and scientists who cheered at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, on Jan. 3, 2004, none predicted the team would still be operating both rovers in 2009. It is to these scientists that one must give all the credit.
The sheer volume of science that the rovers have enabled is astonishing. To sit in a control room in California here on Earth and remotely drive a vehicle millions of miles away, on another planet, climbing hills, travelling over several kilometres, is the best job anyone could do. The rovers have covered greater distances than they were designed to do and have lived far longer than they were expected to. Its a bit sad that they are for eternity exiled to another planet and will never return home.
This is worth checking out too.
