From 2007 the Station-to-Shuttle Power Transfer System (SSPTS; pronounced spits) allowed a docked Space Shuttle to make use of power provided by the International Space Station's solar arrays. Use of this system reduced usage of a shuttle's on-board power-generating fuel cells , allowing it to stay docked to the space station for an additional ...
The large movable "Lira satellite communications antenna" is located on the Zvezda service module near the aft or rear of the International Space Station on this Assembly Compartment. [15] The "Transfer Chamber" is equipped with automatic docking equipment and is used to service Soyuz and Progress spacecraft.
One of the most important modifications that debuted during STS-118 is an upgraded power-distribution module, the Station-Shuttle Power Transfer System (SSPTS). SSPTS allows Endeavour to tap into the ISS power supply, converting up to eight kilowatts of electrical power from 120-volts direct-current (120VDC) ISS main voltage to the 28VDC system ...
ISS Propulsion Module (NASA) The ISS Propulsion module was proposed as a backup to functions performed by the Zvezda Service Module and Progress spacecraft.Critical ISS functionality such as guidance, navigation, control and propulsion are provided only by Russian (Zvezda and Progress) and the European spacecraft.

The mission duration was 15 days and 18 hours, and it was the first mission to fully utilize the Station-to-Shuttle Power Transfer System (SSPTS), allowing space station power to augment the shuttle power systems. The mission set a record for a shuttle's longest stay at the ISS.
Astronauts completed major rewiring of the electrical system of the International Space Station in order to bring online the P3/P4 solar array installed by STS-115 in September 2006. Additional rewiring was done to ISS Pressurized Mating Adapter 2 (PMA2) to enable Station-Shuttle Power Transfer System (SSPTS) commencing with STS-118. [7] [8] [9 ...
Harmony, also known as Node 2, is the "utility hub" of the International Space Station. It connects the laboratory modules of the United States, Europe and Japan, as well as providing electrical power and electronic data. Sleeping cabins for four of the crew are housed here. [3]
After nearly 20 years at the International Space Station, ISS, the Pirs Docking Compartment, SO1, undocked from the nadir (Earth-facing) port of the Zvezda Service Module, SM, on 26 July 2021, at 13:55 Moscow Time (6:55 a.m. EDT) in the joint stack with the Progress MS-16 cargo ship. At the time, the spacecraft was orbiting the Earth over ...
