International Space Station Assembly Flight 7A.1
first trip to the International Space Station was aboard Space
Shuttle Discovery in March 2001.|
Multi-Purpose Logistics Module, which was provided by the Italian
Space Agency (ASI), is the primary payload for STS-105. Leonardo
will be making its second flight to the International Space Station.
It is one of three such pressurized modules that serve as the ISS's
"moving vans," carrying laboratory racks filled with equipment,
experiments and supplies to and from the station aboard the space
reusable logistics modules function as both a cargo carrier and
a space station module when flown. Mounted in the space shuttle's
cargo bay for launch and landing, they are berthed to the station
using the shuttle's robotic arm after the shuttle has docked.
While berthed to the station, racks of equipment are unloaded
from the module and then old racks and equipment may be reloaded
to be taken back to Earth.
Leonardo will be outfitted with 12 racks of experiments and equipment.
Two EXPRESS racks will be transferred to ISS. In addition to these
two racks, there are six Resupply Stowage Racks and four Resupply
Stowage Platforms filled with logistics and supplies requiring
transfer to ISS.
International Space Station Experiment
The Materials International
Space Station Experiment, or MISSE, Project is a NASA/Langley
Research Center-managed cooperative endeavor to fly materials
and other types of space exposure experiments on the International
Space Station. The objective is to develop early, low-cost, non-intrusive
opportunities to conduct critical space exposure tests of space
materials and components planned for use on future spacecraft.
Johnson Space Center, Marshall Space Flight Center, Glenn Research Center, the
Materials Laboratory at the Air Force Research Laboratory and
Boeing Phantom Works are participants with Langley in the project.
experiment will be the first externally mounted experiment conducted
on the ISS. The experiments are in four Passive Experiment Containers,
or PECs, that were initially developed and used for an experiment
on Mir in 1996 during the Shuttle-Mir Program.
Experiments Advancing Technology
Experiments Advancing Technology, or HEAT, is a collection
of Get Away Special (GAS) canisters all under the direction of
Goddard Space Flight Center. It consists of the following experiments:
Carrier Equipment Avionics System|
Advanced Carrier Equipment, or ACE, Avionics System has
been designed to replace the Hitchhiker Avionics.|
is an engineering satellite designed to evaluate the use
of inexpensive commercial hardware for spacecraft. It
is expected that Simplesat will demonstrate Global Positioning
System attitude control and fine pointing control while
in free-flyer low-Earth orbit.|
Experiment Module, or SEM, is housed in a sealed,
extended 0.14-cubic-meter (5-cubic-foot) canister mounted
in the aft position of the port adapter beam. The SEM
will contain up to 10 small, enclosed modules, each containing
a separate, passive experiment designed and constructed
objective of the G-774 experiment is to increase the understanding
of smoldering combustion in a long-term microgravity environment.
This experiment will focus on one-dimensional smoldering
Canister G-780 Payload
The GAS G-780 payload is sponsored by Mayo High School, Rochester,
Minn. The objective of the G-780 experiment is to investigate
cell growth in microgravity. The experiment utilizes six growing
chambers containing various seed types.
