October 6, 2003 Memo
Dear Colleagues:
Dr. Ed Weiler, NASA's Associate Administrator for Space Science recently confirmed Gusev Crater as the landing site for Spirit (MER-A). This confirmation was based on presentations made by the MER Project that included the results of additional airbag tests for the lander, further assessment of mesoscale wind model results for the site, mapping of hazard units throughout Gusev crater, additional landing simulation results, and the conclusions of an independent navigational study. As a result of this confirmation, the MER Project has ceased all work on the Elysium site.
Gusev and Meridiani here we come!

Once again, please accept our most sincere thanks to all of you that helped in the selection of landing sites for the Mars Exploration Rovers. Your time and effort contributed significantly to the process and are greatly appreciated.
Regards, John Grant and Matt Golombek Chairs of the Landing Site Steering Committee
