NASA and Boeing have announced that humanity s celestial outpost will soon install six new solar panels, each capable of producing 20kW.
The panels use Roll-Out Solar Array (ROSA) tech tested at the ISS in 2017. ROSA panels roll open in space like a tape measure , a technique that allows for more compact designs than is possible with rigid panels.
Even with ROSA tech, installing the new panels will require three resupply missions and a dozen spacewalks. The launches will be conducted by SpaceX and start in 2021.
