Mars Week 2001, a three-day conference about the exploration of Mars, will be held at the MIT campus in Cambridge on October 26-28. Mars Week is an annual conference discussing the engineering, scientific, political and social aspects of Mars exploration. Topics will include present and future missions, including the prospects for the human exploration and settlement of the Red Planet. The event will kick off with the arrival of NASA’s Mars Odyssey spacecraft at Mars on Tuesday, October 23. The MIT chapter of the Mars Society will monitor the spacecraft’s entry into Mars orbit from the MIT campus. This will provide an informal start to the Mars Week 2001 program.
