MISSION CONTROL CENTER STS-67 Status Report #8 Monday, March 6, 1995; 8:30 a.m. CST Science operations continued throughout the night as the compliment of Astro-2 instruments mounted in Endeavour's cargo bay gathered information on the birth, evolution and death of stars and galaxies. Crew members also talked with students on the ground during several successful Shuttle Amateur Radio Experiment (SAREX) contacts with schools in Australia, South Africa and India. In addition to supporting the Astro-2 observations, crew members worked with the Commercial Materials Dispersion Apparatus Instruments Technology Associates Experiments (CMIX) biotechnology experiments on board. These experiments use the unique microgravity environment found on the shuttle to aid in the development of drugs and drug delivery systems on the Earth. The Blue Team of astronauts -- Payload Commander Tammy Jernigan, Mission Specialist Wendy Lawrence and Payload Specialist Sam Durrance -- took over orbiter and payload operations shortly after midnight. Their Red Team counterparts ended a busy Flight Day 5 on orbit shortly after 3 a.m. central time. Flight controllers had a troublefree night as Endeavour continued to perform flawlessly in support of Astro-2 objectives. Endeavour is in an orbit of approximately 191 by 186 nautical miles.
