Astronauts installed new solar panels on the International Space Station (ISS) on Sunday. Shane Kimbrough and Thomas Pesquet performed a six-hour space walk to get it done, NASA reports. The old solar panels begin to show signs of decay after twenty years of service. The new ones are needed to continue to supply the space station with sufficient power. The panels are expected to last 15 years. The solar panels were supposed to be installed on Wednesday, but then the team had technical problems. The solar panels are foldable and a total of 19 meters long. The astronauts were tethered to the space station during the mission. The new solar panels were delivered to the space station earlier this month by a SpaceX unmanned rocket. |
