NASA engineers have successfully completed testing on one half of the Nancy Grace Roman Space Telescope — a key step in making sure this future observatory will perform as expected once it reaches space.
"This milestone tees us up to attach the flight solar array sun shield to the outer barrel assembly, and deployable aperture cover, which we'll begin this month," said Jack Marshall, who leads integration and testing for these Roman Space Telescope elements at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
