International Space Station


NASA’s Glenn Research Center is playing a significant role in the development and safe operation of the International Space Station (ISS). Glenn's contributions involve several tasks that support key flight hardware including the design, development and operations of the Electrical Power System (EPS), Plasma Contactor Unit (PCU) system, and Photovoltaic Thermal Control System (PVTCS). Glenn also provides support for the analysis activities of the ISS Environments Team and investigates safety issues to promote propulsion system safety.

 


Sustaining Engineering of EPS Hardware


ISS

The complex Electric Power System (EPS) onboard the International Space Station (ISS) provides all the power vital for the continuous, reliable operation of the spacecraft. NASA Glenn Research Center’s Space Operations Division is leading the sustaining engineering and subsystem integration of EPS hardware. Glenn also manages the integration of the EPS with ISS International Partners’ elements. More information...

 


SPACE Software Tool

To evaluate the overall performance of the Electric Power System (EPS) on the International Space Station (ISS), NASA’s Glenn Research Center is using the System Power Analysis for Capability Evaluation (SPACE) software program. By using this software, Glenn’s Power Systems Analysis Branch analyzes the on-orbit power capability and performance of the EPS. More information...

Environments Team

To ensure the safety of the International Space Station (ISS) crew, NASA Glenn Research Center’s Space Operations Division is supporting the analysis activities of the ISS Environments Team. The ISS environment is being analyzed in four main areas: ionizing radiation, acoustics, external contamination and plasma. More information...


iLIDS

Environments Team logo

The Low Impact Docking System (LIDS) project is developing the next generation docking mechanism that will be used to capture and connect two future space vehicles. The genesis of the LIDS work dates back to the mid 1980s, but a more formal project was formed in 1996 in support of the X-38 Crew Return Vehicle program. The X-38 was a vehicle that would be Shuttle-delivered, would be berthed to the International Space Station (ISS), and would undock and return to Earth in an emergency. While the LIDS design has evolved from one that was based on early developmental requirements into today's LIDS, which meets Constellation requirements, it is still intended to be an advancement in docking mechanism technology to support future docking and berthing operations.

EPS Cooling System


EPS Cooling

The Electric Power System (EPS) components onboard the International Space Station (ISS) must be cooled to sustain the space research experiments and prevent system failures due to overheating throughout the spacecraft. The Photovoltaic Thermal Control System’s (PVTCS) radiator rejects heat into space to keep the power system cool. There will be four PVTCS systems in operation once the ISS assembly is complete.
