NASA’s Nancy Grace Roman Space Telescope team has successfully activated the mission’s Coronagraph Instrument, which will block starlight to view planets and dusty disks around nearby stars. Now the instrument will undergo a monthslong series of calibrations and tests prior to beginning full science operations. The coronagraph power-on began atContinue Reading
Roman’s antenna and visor-like sunshade have successfully deployed. Roman will downlink the highest data volume of any NASA astrophysics mission so far via its high-gain antenna, which measures 5.6 feet wide yet only weighs 24 pounds. It’s made of a carbon composite material that weighs very little but will stillContinue Reading
