Room at Launch Pad 39A to reveal the SPACEHAB Double Module

The top priority of the
docked phase of the mission is to replace four of six 800-ampere
power-producing batteries in Zarya which are no longer operable,
and its associated electronics for proper current regulation.
Zarya will receive additional
new equipment including four cooling fans, three fire extinguishers,
10 smoke detectors and an on-board computer. A suspect radio frequency
power distribution box in Unity used as part of the early S-band
communications system will be replaced during the time Atlantis
is linked to the new international facility.
The crew plans to transfer
almost one ton of equipment from a double Spacehab module housed
at the rear of Atlantis' cargo bay into Zarya and Unity for use
by the Expedition One crew later this year. Those logistical items
include personal clothing and hygiene gear, medical and exercise
equipment, computer equipment and printers, hardware for the eventual
setup and activation of the station's Ku-band communications system
and a centerline camera for Unity's common berthing mechanisms
to which other International Space Station components will be
mated. Four large bags of water will also be brought from Atlantis
into the International Space Station for later use.
double module is a pressurized, mixed-cargo carrier, which supports
various quantities, sizes and locations of experiment hardware.
It augments the orbiter middeck by providing a total cargo capacity
of up to 4,536 kilograms (10,000 pounds) with the ability to accommodate
SPACEHAB will carry logistics and maintenance cargo for the International
Space Station. More than 2,223 kilograms (4,900 pounds) of Russian
and United States supplies -- clothing, personal hygiene articles,
health care supplies, exercise equipment, food, TV and movie equipment,
a fire detection and suppression system, computers and sensors --
will be transferred to the station.
is carrying a commercial payload, the Self-Standing Drawer--Morphological
Transition and Model Substances.
Integrated Cargo Carrier
The SPACEHAB Integrated
Cargo Carrier is used to accommodate and support the transfer
of exterior cargo from the shuttle to the space station. On STS-101,
the ICC will carry three cargoes: parts of the Russian Strela crane,
the Space Integrated Global Positioning System/Inertial Navigation
System Orbital Attitude Readiness payload and the SPACEHAB-Oceaneering
Space System box.
Strela is a Russian crane that will be mounted on Zarya. Some
of Strela's components are already at the station. STS-101 will
deliver the boom, ring and extension to complete the crane assembly.
The Space Integrated Global Positioning System/Inertial Navigation
System Orbital Attitude Readiness payload, or SOAR, is designed
to be the space station's primary global positioning source and
the crew return vehicle's primary navigation source.
The SPACEHAB-Oceaneering Space System box, or SHOSS, is a trunk
mounted on the ICC. On STS-101, it will contain space-walking
tools and logistics items to be transferred and stowed in Unity.
The BioTube Precursor
Precursor Experiment will test newly developed technologies
involved in the BioTube magnetic field apparatus, a device for growing
seeds in microgravity that will be flown on STS-107. This precursor
experiment will evaluate the MFA's water delivery system and seed
germination substrates. The flight will also demonstrate seedling
growth as a function of temperature in the limited volume of the
sealed growth chambers.
Space Experiment Module 6
Ten passive experiments will fly on STS-101 as part of NASA's Space
Experiment Module program, which is managed by the Goddard Space
Flight Center's Wallops Flight Facility in Virginia. The SEM program
is an educational initiative to increase access to space for students
in kindergarten through the university level. The experiments are
sponsored by students in the United States and Argentina.
to America's Remarkable Schools
This life sciences payload, sponsored by the NASA's Kennedy Space
Center, contains 20 experiments from schools across the United
States. The projects include seeds of various types reflown from
SEEDS I and II as well as regionally important seed varieties
such as lettuce and spinach.
Each experiment is placed in a 2-inch-diameter PVC tube inside
a Complex Autonomous Payload/Getaway Special canister. The CAP/GAS
is positioned in space shuttle cargo bay 13.
Micro Wireless Instrumentation System (Micro WIS) HEDS Technology
will demonstrate the operational utility and functionality of the
Micro WIS on orbit, initially in the crew cabin of the shuttle and
then on the International Space Station.
The Micro WIS consists of autonomous, tiny sensors for data acquisition.
Two versions have been developed -- a sensor/transmitter and a
One of the objectives of this HTD is to obtain meaningful real-time
measurements for use in the orbiter's environmental control and
life support system, or ECLSS, operations. This breakthrough in
miniaturization means significant cost, weight and power savings
for current and future space vehicles and ground test facilities
and should revolutionize system design of future spacecraft.
