STS-71 Day 10 Highlights
Back to STS-71 Flight Day 09 Highlights:
- On Thursday, July 6, 1995, 6:30 a.m. CDT, STS-71 MCC Status Report # 18
- The Atlantis crew received a lighthearted wake-up as a parody of the
Beatles' "Hello, Goodbye" and Paul Anka's "Lay Your Head on My
Shoulder" greeted the eight crew members at 1:30 a.m. today.
- Thursday marked the final full day on orbit for the astronauts and
cosmonauts on board Atlantis and preparations for Friday's planned
landing occupied much of their time. Commander Hoot Gibson, Pilot
Charlie Precourt and Mission Specialist Greg Harbaugh powered on one
of Atlantis' hydraulic systems and cycled the flight control surfaces
that will be used during reentry. They also fired the orbiter's
reaction control system jets in the traditional preflight checkout of
the Shuttle's systems prior to Friday's scheduled homecoming.
- Even as crew members prepared to return home, the pace of biomedical
investigations in the Spacelab module continued with the Mir 18 crew
members --Vladimir Dezhurov, Gennady Strekalov and Norm Thagard.
Thagard and Strekalov once again climbed into the bag-like Lower Body
Negative Pressure device which pulls fluids from the upper body to the
lower extremities. Sessions in the LBNP are part of the
countermeasures program to prepare the Mir 18 crew to return to Earth
following more than 100 days in orbit.
- Also in the Spacelab, Harbaugh will join Mission Specialist Ellen
Baker in setting up the special recumbent seats the Mir 18 crew
members will occupy during reentry. Baker and Bonnie Dunbar also will
begin deactivating some of the Spacelab's systems in anticipation of
Friday's landing. Some systems will remain powered on so that
exercise equipment in the Spacelab module is available to crew members
in the event weather precludes a landing Friday morning.
- Early, at 2:15 a.m., a voice check from the new flight control room
in Mission Control to the orbiting shuttle was successfully completed.
STS-71 is scheduled to be the last shuttle mission to use the current
mission control center for on-orbit operations. Beginning with
STS-70, set for launch on July 13, on-orbit flight control will take
place in the new flight control room. Wednesday night at 8:16, flight
controllers in Houston passed a milestone as communications commands
issued from the new flight control room in Mission Control were
successfully uplinked to Atlantis. The commands were sent as Atlantis
flew 218 nautical miles above the Indian Ocean.
- On Thursday, July 6, 1995, 5 p.m. CDT, STS-71 MCC Status Report # 19
- The crew of Atlantis packed up today and double-checked equipment in
preparation for tomorrow's return home.
- Earlier in the day, Commander Hoot Gibson and Pilot Charlie Precourt
checked the equipment and instruments Atlantis will use for landing,
finding all systems working properly. Following that checkout, they
test-fired Atlantis' 38 primary steering thrusters, finding one rear,
upward-firing jet failed and all others working well. The failed jet
has several other jets that are backups and can perform the same
function for the Shuttle and is not an issue for the landing.
- After final exercise sessions by members of the Mir 18 crew, the
Spacelab module was packed up by Payload Commander Ellen Baker and
Mission Specialist Bonnie Dunbar in preparation for entry. Also,
reclining seats were installed in the lower deck of Atlantis for the
Mir 18 crewmen, Commander Vladimir Dezhurov, Flight Engineer Gennady
Strekalov and astronaut Norm Thagard. The three, on their 115th day
in orbit tomorrow, will ride in the seats for the landing, allowing
them to take the forces of reentry in a reclined position.
