The PSA is an astronaut support device designed to move and operate
independently in the microgravity environment of space-based vehicles.
The PSA will assist astronauts who are living and working aboard the
Space Shuttle, Space Station, and during future space exploration
missions to the Moon and Mars.
1. Environmental Monitoring: The PSA patrols astronaut living quarters
and laboratories and monitors oxygen, nitrogen, carbon dioxide, and
other gas levels. The PSA can also monitor experimental data such as
microgravity levels, temperature, and atmospheric pressure.
2. Communications: The PSA functions as a remote, mobile data display
terminal for system and experimental data. The PSA has both
communication input and output capabilities, including a microphone,
speakers, camera, and flat display panel. These features allow for
video and audio conferencing, as well as a wireless relay to link to
hardwired communication systems.
3. Remote Operations Support: Ground Controllers are able to
communicate with the PSA and maneuver the device into the desired
location. Once in position, the PSA will, for example, use its on
board sensors to monitor the status of experimental lab animals in
holding bays or provide the Ground Controllers with remote views of
mission operations.
4. Crew Worksite Support: The PSA provides astronauts work site access
to such information as vehicle status and health data, mission
schedule, inventory tracking, location information, and
just-in-time-training support. The PSA also has the ability to provide
notification updates and alarms related to system events, payload
events, or mission experiments
