MISSION CONTROL CENTER
STS-67 Status Report #7

Sunday, March 5, 1 p.m. CST

Endeavour is still providing a trouble-free platform for the Astro-2
ultraviolet observations as well as the mission's engineering,
materials processing and biotechnology experiments.

There have been some indications that the crew's stationary bicycle
exercise is imparting some vibration to the shuttle that is
interfering with the Instrument Pointing System's ability to precisely
direct the Astro-2 telescopes at their targets. The crew is being
asked to schedule exercise a little earlier so that the vibration has
stopped by the time Endeavour moves into darkness and celestial
observations must resume.

The Red Team -- Commander Steve Oswald, Pilot Bill Gregory, Mission
Specialist John Grunsfeld and Ron Parise -- assumed the duty shift
shortly after noon, and the Blue Team -- Payload Commander Tammy
Jernigan, Mission Specialist Wendy Lawrence and Payload Specialist Sam
Durrance -- is getting ready for bed.

Oswald is scheduled to work with the Middeck Active Control Experiment
as time allows on this shift, repositioning cameras to give ground
controllers better insight into MACE's performance. MACE is designed
to measure how disturbances caused by one payload affect nearby
payloads attached to the same supporting structure. Overnight, they
successfully accomplished some maintenance on the Ku-Band Interface
System, and that system is now able to ship data to and from the
ground as planned.

   Gregory will conduct another run on the PILOT flight trainer, a
combination of a laptop computer and control stick that he and the
commander use to practice shuttle landings.

  Flight controllers in Houston have no mechanical problems to deal
with as Endeavour continues to orbit the Earth at an altitude of 191
by 187 nautical miles.
