On Thursday, NASA astronauts Woody Hoburg and Steve Bowen updated the power supply of the International Space Station by putting in a new roll-out solar array.
The Expedition 69 flight engineers Hoburg and Bowen finished their five hours and thirty five minute spacewalk just before 2:30 p.m. EDT.
The installation of an ISS Roll-Out Array, or IROSA, to increase power generation for the 1B power channel on the station’s starboard truss backbone, was their primary goal, according to NASA.
Solar panels connected in groups, or arrays, absorb sunlight and provide electricity for the space station. In 2017, the ISS utilised a robotic arm to unfold its first IROSA.
