INTERNATIONAL SPACE STATION STATUS REPORT #01-8
4 p.m CST, Wednesday, March 28, 2001
Mission Control Center, Houston, Texas
The International
Space Station has become home to its new residents – the Expedition
Two crew of Commander Yury Usachev and Flight Engineers Jim Voss and
Susan Helms – who are settling in for a four-month stay after assuming
command of the complex 10 days ago.
Minor issues being
worked by the crew and flight control teams in Houston and Moscow are
not impacting the operation and health of the complex, but are occupying
time of engineers in preparing troubleshooting procedures for items
on board.
The activation
of the station’s Ku-Band antenna is on standby until procedures
are put in place for a possible software patch to account for an apparent
pointing error with the dish-shaped antenna. The Ku Band system is used
to transmit television, voice and high-speed data to the ground. Normal
communication is being managed through the S-Band audio system. Any
required TV images, in the meantime, can be accommodated through the
use of the laptop computer-based digital video system. Until that problem
is corrected, transmission of experiment data from the Human Research
Facility experiment rack in the Destiny laboratory is on hold.
A Destiny condensate
venting system is not working and while troubleshooting continues, the
thermal loop temperatures have been increased so that no water currently
is being condensed. As a point of verification, a contingency water
container has proven to be useful in serving as a storage location for
condensate, if required.
In and around maintenance
tasks and routine housekeeping chores, the crew has been busy setting
up additional equipment and conducting status checks on some of the
payloads. A new bicycle exercise machine called CEVIS (for Cycle Ergometer
with Vibration Isolation System) was setup this week, while engineers
assess the work needed to repair the station’s treadmill, which
is showing wear in many of the slats that provide support to the unit
designed to allow exercise with little or no vibration that could impact
sensitive experiment work.
The Progress supply
craft docked to the Zvezda module delivered 89 kilograms of oxidizer
to the service module’s storage tanks via remote commanding from
the ground. The Progress will be undocked from the station in mid-April
in preparation for the arrival of the next shuttle flight carrying the
station’s Canadian-built robot arm and another Italian Space Agency
supplied logistics module called Raffaello.
The Progress undocking
provides an open port for the relocation of the Soyuz capsule around
April 16-18 which will provide clearance for the placement of Raffaello
during the shuttle mission, which launches April 19.
Later this week
the Expedition Two crew is scheduled to perform some maintenance work
in an attempt to get the carbon-dioxide removal assembly in Destiny
working. The plan calls for a test of a cable to ensure it is working
before changing the pump with a spare brought up on the most recent
shuttle flight. As of now, with only three people onboard, carbon dioxide
removal from the cabin air is adequately conducted by Zvezda’s
Vozdukh system.
The crew plans
to take part in its first interview opportunity on Friday with reporters
from CBS and the Associated Press at 10 a.m. CST Friday. The interview
will be broadcast on NASA TV, but will be audio only.
Meanwhile down
at the Kennedy Space Center in Florida, the crew of shuttle mission
STS-100 is conducting its traditional countdown dress rehearsal in preparation
for launch to the ISS April 19. The international crew consists of Commander
Kent Rominger, Pilot Jeff Ashby, Flight Engineer John Phillips, Mission Specialist Scott Parazynski, Canadian astronaut Chris Hadfield, European
astronaut Umberto Guidoni and Russian Aviation and Space Agency cosmonaut
Yuri Lonchakov.
The International
Space Station continues to orbit the Earth in good shape at an altitude
of 238 statute miles (384 km). The next ISS Status Report will be issued
April 4.
