NASA's Roman Space Telescope Instruments Achieve Precise Alignment for Science Operations

The Nancy Grace Roman Space Telescope has reached a critical milestone, successfully aligning its optics and instruments. This precise calibration is essential for the observatory to achieve its scientific goals, which require stability at least ten times greater than the Hubble or Webb space telescopes. The team conducted test observations to measure and correct for tiny shifts caused by launch vibrations, temperature changes, and the absence of gravity in space, bringing the mission closer to full science operations.
