Containers carrying set of seeds for a Materials International Space Station Experiment (MISSE) are shown Feb. 11, 2021, at NASA’s Kennedy Space Center in Florida. The containers will fly aboard Northrop Grumman’s Cygnus spacecraft as part of NG-15, a NASA commercial resupply mission to the orbiting laboratory targeted for Feb. 20, 2021. They will be placed in the MISSE testing facility, located near the space station’s solar arrays, where they will be exposed to the extreme environment of space for six months before returning to Earth for further study.
