- MISSION CONTROL STATUS REPORT
- REPORT 8
-
- Oct. 8, 1990. Flight Day 3
- MET 02/00:27
- CDT 7:15 a.m.
-
- The STS-41 crew continues to direct its attention to
- secondary science and operational investigations during the
- mission's third flight day.
-
- STS-41 crew members completed a waste water dump on
- orbit 33 over the southeastern U.S. as part of detailed test
- objective (DTO) 330 about 7:02 a.m. CDT or a MET of 2/00:18. The
- DTO is designed to give investigators a clear definition of the
- water's plume with respect to the orbiter. Interest in
- documenting this event resulted after STS-61A when water from an
- orbiter waste/supply water dump recontacted the orbiter.
-
- STS-41 Mission Specialists Bill Shepherd and Bruce Melnick
- worked with the Voice Command System (VCS) this morning. This was
- the second of three sessions in which Shepherd and Melnick are
- testing a device designed to allow voice control of the orbiter's
- television cameras. The system failed to recognize nine words in
- its 31 word vocabulary during Shepherd's session. Melnick
- reported better success, having difficulty with only two words.
-
- The VCS works on personalized "templates" to identify the
- user. The templates are computer chips that recognize the human
- voice and make "imprints" of words, which it stores as commands.
- Investigators had speculated the system might encounter some
- difficulty in identifying Shepherd and Melnick's voices because
- microgravity can change voice characteristics. The crew's final
- session with the VCS is scheduled for about 6:30 a.m. tomorrow or
- a MET 3/00:30.
-
- Later today crew members will work with the Shuttle Solar
- Backscatter Ultraviolet (SSBUV) experiment, Chromosome and Plant
- Cell Division (CHROMEX-2) and DTO 1206 the Cursor Control Device.
