NASA’s Nancy Grace Roman Space Telescope team completed a marathon of activities to fine-tune the observatory’s vision and prepare the primary instrument for routine use. “All of Roman’s sweeping surveys will rely on the Wide Field Instrument,” said Dave Hickey, a Wide Field Instrument systems engineer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Many of the mission’s primary goals, like studying dark matter and dark energy, wouldn’t be possible without it, so it’s both exciting and a huge relief to see that it’s working well!”
