Imaging scientists Dr. Michael Malin and Dr. Ken Edgett from
NASA’s Mars Global Surveyor spacecraft will present what they
describe as their most significant discovery yet at a Space
Science Update at 2:00 p.m. EST on Thursday, Dec. 7. Their
findings are being published in the December 8 issue of Science
Magazine.

This science update will be held in the James E. Webb Auditorium

carried live on Telstar 5, transponder 11. The Ku-band satellite
is located 97 degrees West longitude with a downlink frequency of

available.
