MISSION CONTROL CENTER
STS-67 Status Report #20

Sunday, March 12, 9:30 am CST

Three of Endeavour's astronauts continued scientific observations with
the cluster of telescopes in the payload bay throughout the night and
early morning.

Tammy Jernigan, Sam Durrance and Wendy Lawrence assisted ground
controllers in Alabama with fine-pointing of the three telescopes.
For the first time, an observation was made of the Moon as the Shuttle
passed south of Hawaii on the 161st orbit of the mission in an effort
to gather ultraviolet data to help determine the Moon's origin.
Several additional observations of moons and asteroids will be made
throughout the mission.

The remaining crew members -- Steve Oswald, Bill Gregory, John
Grunsfeld and Ron Parise -- will wake up about 10 this morning and
take over for their three co-workers at noon.

The astronauts responded to questions throughout the day from people
around the world who have inquired on the Internet about various
aspects of the mission and spaceflight in general.

Endeavour is circling the Earth every 91 minutes in a slightly
elliptical orbit of 196 by 182 nautical miles with no systems problems
to report. The STS-67 mission, which is planned to be the longest in
Shuttle history, is scheduled to end Friday with a landing at mid-
afternoon at the Kennedy Space Center.
