'Lighting Up the Nighttime Sky': 10 Years Since STS-116 Brought Power to the Space Station (Part 1)

In addition to delivering the P-5 truss segment (visible at the far-right side of the P-4 arrays), the STS-116 crew retracted the port-side array of the P-6 segment. This produced an asymmetric configuration when Discovery departed the space station. Image Credit: NASA

Ten years ago, this month, the crew of Shuttle Atlantis—Commander Brent Jett, Pilot Chris Ferguson, and Mission Specialists Joe Tanner, Dan Burbank, Heidemarie Stefanyshyn-Piper, and Canada’s Steve MacLean—roared into orbit to restart the […]

In For the Long Haul: 10 Years Since STS-115 (Part 1)

Joe Tanner had already performed five EVAs before STS-115 left Earth. By the time he returned from the mission, he had completed seven EVAs and spent 46.5 hours outside a spacecraft. Even today, he stands as the 13th most seasoned spacewalker of all time. Photo Credit: NASA, via Joachim Becker/SpaceFacts.de

On a day which spelled calamity for SpaceX—as its Upgraded […]

Spacewalkers Ready for US EVA-37, Days Ahead of Expedition 48 Crew Return

Expedition 45 spacewalker Kjell Lindgren works to restore the P-6 cooling system to its pre-2012 configuration during U.S. EVA-33 in November 2015. He and Scott Kelly ultimately left the Trailing Thermal Control Radiator (TTCR) fully deployed when the crew ran out of time and encountered other difficulties. Photo Credit: NASA

Fifteen years ago, next week, power—in the form of two immense, electricity-generating solar arrays, […]

'No Impacts' to Expedition 45 Crew, as 1B Channel on S-6 Truss Suffers Power Loss

The S-6 truss and its two expansive Solar Array Wings (SAWs) are deployed during the STS-119 shuttle mission in March 2009. “Channel 1B,” one of the two power channels aboard the S-6 truss, is believed to have fallen victim to a power short, which tripped its Direct Current Switching Unit (DCSU). The cause […]
