Pre-Flight Briefings for Upcoming Microgravity Science Laboratory Flight Set for March 18

A series of briefings to preview the activities and objectives of NASA's upcoming Microgravity Science Laboratory-1 (MSL-1) mission will be held on Tuesday, March 18 at the Johnson Space Center (JSC), Houston, TX, and the Marshall Space Flight Center (MSFC), Huntsville, AL.

During the mission, designated STS-83, Space Shuttle Columbia's seven-person crew will perform a variety of experiments designed to study the effects of weightlessness on various materials. The pressurized Spacelab module, which serves as an orbiting laboratory, also will serve as a testbed for the International Space Station by having the MSL-1 experiments and activities verify some of the hardware, facilities and procedures that will be used on the international complex.

The STS-83 pre-flight briefings will begin at JSC at 8:30 a.m. CST with a mission overview briefing by Lead Flight Director Rob Kelso. At 9:30 a.m. CST the briefings will switch to MSFC for a presentation on the science planned during the MSL-1 flight. NASA's daily Video File will air at its regular time of 11 a.m. CST. At 11:30 a.m. CST the briefings move back to JSC for a presentation on the Cryogenic Flexible Diode (CRYOFD) heat pipe experiment. The final briefing of the day will take place at 1 p.m. CST with the crew news conference.

All of the briefings will be carried on NASA Television with two-way question and answer capability from participating NASA centers. Special Note about NASA Television: As of March 15, NASA Television will be broadcast at a new satellite location. The new satellite is GE-2, Transponder 9C at 85 degrees West longitude, frequency 3880.0 MHz, audio 6.8 MHz.
