STS-105 Day 7 Highlights
Back to STS-105 Flight Day 06 Highlights:
- On Thursday, August 16, 2001, 6:00 a.m. CDT, STS-105 MCC Status Report # 12
- On the 1000th day since the launch of the first module of the
International Space Station, Discovery's astronauts were awakened
shortly after 4 a.m. Central time to the sounds of "The Marvelous Toy"
by Tom Paxton for Mission Specialist Dan Barry from his wife.
- Barry and crewmate Pat Forrester will conduct the first space walk
of Discovery's flight to the International Space Station at around
9:30 this morning to install the Early Ammonia Servicer on the
station's P6 truss structure. The servicing unit contains spare
ammonia that could be used in the station's cooling system, if needed.
- They also will attach an experiment to the station to expose samples
of materials to the space environment. Carrying the acronym MISSE, for
Materials International Space Station Experiment, it contains about
1,500 samples of materials in two suitcase-like containers. The
samples will remain outside the station for about a year, then will be
returned to Earth for analysis.
- Discovery Commander Scott Horowitz will operate the shuttle's
robotic arm during the space walk. Pilot Rick Sturckow will serve as
the space walk choreographer from inside the shuttle's cabin during
the 6=-hour space walk, which will be staged from Discovery's airlock.
- A second space walk is planned for Saturday. Barry and Forrester
will hook up heater cables for another truss structure to be delivered
to the station next year.
- Aboard the ISS, the computers of the Zvezda Service Module once
again commanded the station's gyroscopes to assume control of the
orientation of the complex at around 5 a.m. after Russian flight
controllers completed their loading of upgraded software commands to
those computers. In the meantime, Discovery maintained control of the
complex until the computer upgrades were completed with no impact to
- While Barry and Forrester conduct their space walk, the Expedition
Three crew, Commander Frank Culbertson, Pilot Vladimir Dezhurov and
Flight Engineer Mikhail Tyurin, will continue stowage of equipment and
supplies inside the Leonardo Multi-Purpose Logistics Module for return
to Earth. The Italian-built pressurized module brought almost 7,000
pounds of equipment, supplies and two scientific experiment racks to
- At 7:10 this morning, Culbertson and his crewmates plan to offer a
few commemorative words to mark the 1000th day in space for the
International Space Station since the Zarya module was launched on
November 20, 1998 from the Baikonur Cosmodrome in Kazakhstan.
- Discovery and the station are orbiting the Earth every 90 minutes at
an average altitude of 244 statute miles with all systems functioning
- On Thursday, August 16, 2001, 6:00 p.m. CDT, STS-105 MCC Status Report # 13
- Astronauts Dan Barry and Pat Forrester completed the first of two
planned space walks during Discovery's voyage to the International
Space Station. The excursion lasted 6 hours, 16 minutes and involved
installing the Early Ammonia Servicer and the first external
experiment on the station's hull. The servicer contains spare ammonia
that can be used in the space station's cooling systems if needed. The
Materials ISS Experiment (pronounced 'missy' by its acronym) will
expose 750 material samples to the space environment for about 18
months before being returned home late next year. During the space
walk, Discovery's Commander Scott Horowitz operated the shuttle robot
arm, and Pilot Rick Sturckow choreographed the space walk from the
orbiter's flight deck. This was the 25th space walk devoted to the
construction of the space station and the 12th this year. Barry and
Forrester will perform the mission's second space walk on Saturday to
hook up heater cables for another truss structure to be delivered to
the station next year. Mission managers Friday will evaluate the
consumables onboard Discovery and assess the progress made by the
crews in transferring items into the Leonardo logistics module from
the station before making a determination as to whether the docked
phase of the flight should be extended by one day.
- Earlier today, the computers inside the Zvezda module once again
assumed control of the station's attitude - or position in space --
after Russian flight controllers completed the loading of upgraded
software commands to those computers. In the meantime, Discovery
maintained control of the complex until the computer upgrades were
completed with no impact to station operations.
- The Expedition Three crew --Commander Frank Culbertson, Pilot
Vladimir Dezhurov and Flight Engineer Mikhail Tyurin -- earlier today
offered commemorative remarks on the occasion of the 1000th day in
space for the International Space Station since the Zarya module was
launched on Nov. 20, 1998 from the Baikonur Cosmodrome in Kazakhstan.
- Discovery and the station are orbiting the Earth every 90 minutes
at an average altitude of 244 statute miles with all systems
