Two NASA astronauts will conduct a spacewalk early Wednesday (Dec. 21) to put in new solar arrays on the Worldwide House Station (ISS), and you’ll watch it reside.
Josh Cassada and Frank Rubio are scheduled to enterprise exterior the orbiting lab at 7:45 a.m. EST (1245 GMT) Wednesday on a spacewalk anticipated to final about seven hours. You may observe the motion reside right here at House.com, courtesy of NASA, or directly via the agency (opens in new tab), starting at 6:30 a.m. EST (1130 GMT).
Cassada and Rubio will set up a brand new ISS Roll-Out Photo voltaic Array (iROSA), the fourth of six such buildings pegged for the orbiting lab’s exterior. The iROSAs will increase the station’s present solar panel system; when all six are up and working, the orbiting lab’s energy provide will improve by 20% to 30%, NASA officers have stated.

NASA astronaut Nicole Mann and Japan’s Koichi Wakata will help Cassada and Rubio on Wednesday from contained in the orbiting lab.
Mann and Wakata “will likely be on the robotics workstation commanding Canadarm2 and aiding the spacewalking duo in the course of the fine-tuned set up job,” NASA officers wrote in an update on Tuesday (opens in new tab) (Dec. 20).
Wednesday morning’s spacewalk was initially scheduled to happen on Monday (Dec. 19). However NASA pushed it again two days, as a result of the company needed to make use of the cameras on the tip of the robotic, 57.7-foot-long (17.6 meters) Canadarm2 to examine a leaky Russian Soyuz capsule that is docked with the ISS.
That Soyuz, referred to as MS-22, suffered a coolant leak on Dec. 14, as two Russian cosmonauts have been prepping for a spacewalk of their very own (which ended up being canceled).Â
In the course of the Sunday (Dec. 18) Soyuz inspection, Canadarm2’s cameras spotted a small hole close to the suspected leak web site. Russian space officers are learning the outlet as they attempt to decide the flightworthiness of the Soyuz, which is meant to return Rubio and two cosmonauts to Earth in March. If MS-22 cannot fly safely, Russia will launch one other Soyuz to the ISS to take the trio house.
