			      STS-67 Status Report # 17

Friday, March 10, 5 PM CST

Endeavour's astronauts sailed smoothly on in pursuit of astronomical
research today in their ninth day in orbit.

With all of the Shuttle's systems operating in excellent shape, the
Red team assumed duties aboard Endeavour at mid-morning, aiming the
trio of ASTRO-2 telescopes at various stellar objects as the Blue team
turned in for an eight-hour sleep period. The Blue team astronauts
will awaken tonight at 10 PM CST to begin another night of work in
orbit.

Commander Steve Oswald conducted more work with the Middeck Active
Control Experiment, the MACE device, which is collecting engineering
data about the effect of vibrations on free-floating structures.

Pilot Bill Gregory spent some time answering questions sent by
computer users on the Internet regarding Endeavour's astronomy
mission. Hundreds of thousands of questions have been placed on the
Internet since the start of the mission, prompting the astronauts to
respond when time permits.

The Red team will be on duty until late tonight when the Blue team
will resume command of astronomical and orbiter operations.

Endeavour is functioning in a nearly flawless state, orbiting every 91
minutes at an average altitude of 190 nautical miles.
