MISSION CONTROL CENTER STS-67 Status Report #9 Monday, March 6, 1995; 5 p.m. CST Flight controllers on the ground and the seven astronauts on board Endeavour continued to work together today as the trio of Astro-2 instruments in the cargo bay gathered information on the "hidden" universe through observations of the ultraviolet spectrum. The STS-67 astronauts also worked with several microgravity experiments and talked with students on the ground around the world through the Shuttle Amateur Radio Experiment. The Blue Team -- Payload Commander Tammy Jernigan, Mission Specialist Wendy Lawrence and Payload Specialist Sam Durrance -- worked with the Commercial Materials Dispersion Apparatus Instruments Technology Associates Experiments (CMIX) and checked on the health of the Protein Crystal Growth biotechnology experiments. Lawrence also sent special greetings to the 19 men and women who reported to the Johnson Space Center today representing the Astronaut Class of 1995. The Red Team -- Commander Steve Oswald, Pilot Bill Gregory, Mission Specialist John Grunsfeld and Payload Specialist Ron Parise -- went on duty about noon CST. As Grunsfeld and Parise supported Astro-2 observations, Oswald coordinating a successful data transfer that will help Middeck Active Control Experiment scientists and engineers design large spacecraft. Gregory practiced for the end of the 15 1/2 day mission on the PILOT landing simulator. Flight controllers had a trouble-free day as Endeavour continued to perform with zero defects in support of Astro-2. Endeavour is in an orbit of approximately 191 by 186 nautical miles.
