MISSION CONTROL CENTER
				  STS-67 STATUS REPORT # 23


Monday, March 13, 5 PM CST


Endeavour's astronauts gathered more ultraviolet data from their suite
of telescopes in the cargo bay today as their mission headed into the
homestretch.

The Red team took over scientific research duties from the Blue team
at mid-morning and spent the day aiming the ASTRO-2 payload at a
variety of distant celestial objects for researchers at the Payload
Operations Control Center at the Marshall Space Flight Center.  The
Blue team turned in at 2 PM CST to begin an eight-hour sleep period.

Commander Steve Oswald spent most of the day working in the middeck
with the MACE experiment, the Middeck Active Control Experiment, a
device rigged with sensors to measure the degree of vibration on
free-floating structures. Engineering data from the experiment will be
used by technicians in the design of spacecraft of the future.

Oswald and Mission Specialist Wendy Lawrence, both graduates of the
Naval Academy, joined Payload Specialist Ron Parise to discuss various
aspects of the flight with Midshipmen gathered at Annapolis. Lawrence
is the first female graduate of the Naval Academy. The in-flight
interview also featured greetings to the crew from former astronaut
Charles Bolden, who currently serves as the Deputy Commandant at
Annapolis.

The crew also continued to answer questions from interested observers
around the world who have inquired about various aspects of the flight
on the Internet.

Headed for a Shuttle-record 15 and a half days in space, Endeavour
continues to circle the Earth every 91 minutes in excellent shape,
orbiting at an average altitude of about 185 nautical miles.
