Prior to the shut down of work last month in response to the coronavirus disease 2019 (COVID-19) pandemic, NASA’s Space Launch System (SLS) Program was working towards milestones for its first two launches. At Stennis Space Center in Mississippi, Core Stage prime contractor Boeing was getting ready to do powered checkouts of the first flight article ahead of the two major tests in the Stage’s Green Run campaign there. Subsystem testing in support of readiness for the Green Run test and for the Artemis 1 launch was also being performed at the Marshall Space Flight Center (MSFC) in Alabama and in Florida.
