Spacewalkers Thomas Pesquet of ESA (European Space Agency) and Akihiko Hoshide of JAXA (Japan Aerospace Exploration Agency) set up the 4A channel on the International Space Station’s P4 (Port) truss segment for the installation of an roll-out solar array. Launched on Nov. 24, 2021. Installed on Nov. 26, 2021.
NASA spacewalker Stephen Bowen works to release a stowed roll-out solar array before installing it on the 1A power channel of the International Space Station’s starboard truss structure. Launched on Nov. 26, 2022. Installed on Dec. 3 and 22, 2022. The roll-out siolar arrays augment the International Space Station’s eight main solar arrays.
As expected, the efficiency of the station’s original solar arrays has degraded over time. NASA is upgrading the space station’s power system with the new roll-out solar arrays — at a cost of $103 million — which will partially cover six of the station’s eight original solar panels.
Launched on June 6, 2023. Installed on June 9 and 15, 2023. The roll-out siolar arrays augment the International Space Station’s eight main solar arrays. They produce more than 20 kilowatts of electricity and enable a 30% increase in power production over the station’s current arrays.
Two astronauts floated outside the International Space Station Wednesday and attached a rolled-up solar array, the first of six intended to boost the lab's power back to factory fresh levels. CBSN's Lana Zak has the details.
They produce more than 20 kilowatts of electricity and enable a 30% increase in power production over the station’s current arrays.
