Instruments on NASA’s Roman Space Telescope Get in Sync for Science
NASA's Nancy Grace Roman Space Telescope has reached a key milestone by bringing its instruments into precise alignment, a step toward science operations. Program scientist Dominic Benford said Roman needs to be at least ten times more stable than Hubble or Webb because of the wide views and tight measurement uncertainties the mission requires. Teams aligned the optics on the ground, then used test observations to measure shifts from launch, temperature changes and weightlessness and to update the observatory's internal map, including how the Wide Field Instrument's 18 detectors lock onto guide stars.
