STS-85 Day 8 Highlights
Back to STS-85 Flight Day 07 Highlights:
- On Thursday, August 14, 1997, 6:00 a.m. CDT, STS-85 MCC Status Report # 16
- Much of the first half of Discovery's seventh day in space was spent
rotating the orbiter back and forth to support deep space viewing of
Comet Hale-Bopp while in darkness and measuring the Sun's energy input
to Earth's atmosphere while in daylight.
- The wake up call to the crew came at 11:41 last night. The
song."You Will Go to the Moon" by Moxy Fruvous signalled the start of
flight day eight for the STS-85 crew which consists of Commander Curt
Brown, Pilot Kent Rominger, Mission Specialists Jan Davis, Bob Curbeam
and Steve Robinson, and Canadian Payload Specialist Bjarni Tryggvason.
- Soon after wakeup, Brown put Discovery through a series of maneuvers
to support Hale-Bopp viewing using a small ultraviolet emission
detecting telescope mounted in the side-hatch window of the orbiter.
Robinson oversaw operation with the telescope. When Discovery moved
into daylight, Brown repositioned the payload so that the Solar
Constant experiment's radiometers could measure the Sun's total energy
input into the Earth's atmosphere.
- Meanwhile, flight planners are discussing whether or not to conduct
further ground commanded maneuvers of the Manipulator Flight
Demonstration experiment after yesterday's testing was cut short.
Should additional time be granted, the work with the small robotic arm
in the payload bay would likely occur tomorrow.
- Tryggvason continues his work with the Microgravity Vibration
Isolation Mount experiment and Curbeam spent the morning overseeing
activities with the Bioreactor Demonstration System designed to
perform cell biology experiments under controlled conditions.
- A morning thruster firing of Discovery's reaction control system
jets by Brown and Rominger continues to maintain the desired distance
from the CRISTA-SPAS satellite so that investigators can communicate
with the spacecraft using the shuttle as a conduit for the link. The
satellite is scheduled to be placed back aboard the orbiter Saturday
- The STS-85 crew is scheduled to go to bed about 2:30 this afternoon
and receive a wakeup call from Mission Control at 11:41 tonight.
- On Thursday, August 14, 1997, 5:00 p.m. CDT, STS-85 MCC Status Report # 17
- Following a week of activities that included the deployment of an
atmospheric satellite, evaluation tests of hardware and software to be
used on the future International Space Station and work with numerous
science and technology experiments, the STS-85 astronauts enjoyed some
time off before they enter the home stretch of their 11-day mission.
- Commander Curt Brown, Pilot Kent Rominger, Mission Specialists Jan
Davis, Robert Curbeam, Steve Robinson and Payload Specialist Bjarni
Tryggvason from the Canadian Space Agency were given a half day off as
is normally done on longer shuttle missions to keep the crew well
rested and operating at peak efficiency. The crew is in a nine-hour
sleep period that began at 2:41 p.m.
- This morning, Robinson again used the Southwest Ultraviolet Imaging
System (SWUIS), a 7-inch imaging telescope that is pointed out of the
orbiter's middeck hatch window, to observe the Hale-Bopp
comet. Curbeam continued his work with the Bioreactor Demonstration
System designed to perform cell biology experiments under controlled
conditions. Tryggvason spent part of his time troubleshooting a
computer hard drive system that support the Microgravity Vibration
Isolation Mount experiment.
- As the shuttle crew entered the final portion of its flight, the new
Mir 24 crew of Commander Anatoly Solovyev and Flight Engineer Pavel
Vinogradov, who arrived on the station the same day Discovery was
launched, bid farewell to Mir 23 Commander Vasily Tsibliev and Flight
Engineer Alexander Lazutkin who are returning home after 185 days in
space. The Soyuz vehicle carrying the Mir 23 crew home undocked from
the station at 3:56 a.m. CDT. Following a four-minute deorbit burn at
6:22 a.m. and journey through the atmosphere, their spacecraft landed
in Central Asia at 7:17 a.m. CDT. After Tsibliev and Lazutkin landed,
they were flown to the Gagarin Cosmonaut Training Center outside of
Moscow, where they will undergo medical exams and debriefings about
their mission. They were reunited with their families shortly after
returning to the Star City facility.
- When the Discovery crew resumes full-up operations Friday, it will
have one additional experiment activity. Mission managers have
approved a plan to conduct further ground commanded maneuvers of the
small mechanical arm associated with the Manipulator Flight
Demonstration payload that were not completed during yesterday's
testing session. The STS-85 astronauts are scheduled to receive a
wake-up call from Mission Control at 11:41 p.m. tonight to begin their
ninth day of on orbit activities.
