Engineers at L3Harris Technologies in Rochester, New York, have combined all 10 mirrors for NASA’s Nancy Grace Roman Space Telescope. Preliminary tests show the newly aligned optics, collectively called the IOA (Imaging Optics Assembly), will direct light into Roman’s science instruments extremely precisely. This will yield crisp images of space once the observatory launches. “This is the pre-launch first light, our first time seeing through the entire telescope,” said Joshua Abel, the lead systems engineer for the Roman Space Optical Telescope Assembly at NASA’s Goddard Space Flight Center in…
