one step closer to collecting data. It reached its final mapping orbit of
approximately 229 miles above the surface Mars
on February 19th. Now scientists are
beginning to power up and calibrate the many instruments on the satellite.
"Reaching our mapping orbit has been a long time coming for all involved.
We are delighted to finally be able to do this mission as it was designed,
in the proper mapping orbit with all the instruments working at their full
potential," said Dr. Arden Albee, the Mars Global Surveyor project
scientist at the California Institute of Technology.
The orbit is specially designed so that the satellite will pass over the
same part of Mars at the same time of day. This is necessary so that
scientists will be able to distinguish diurnal changes from long-term
