NASA has activated the primary instrument and checked out the coronagraph on the Nancy Grace Roman Space Telescope, marking a major milestone for the upcoming observatory designed to study dark energy and exoplanets, according to NASA Science. Technicians have completed the construction of the observatory, which features a primary mirror measuring 7.9 feet, or 2.4 meters, in diameter, matching the physical size of the Hubble Space Telescope’s primary mirror, as reported by NASA Science.
Instrument Capabilities and Wide-Field Imaging
The mission relies on two main instruments: the Wide Field Instrument and the Coronagraph Instrument technology demonstration, according to NASA Science. The Wide Field Instrument serves as the primary tool and is equipped with a massive 300-megapixel camera, as detailed by ScienceDaily. According to NASA Science, the Wide Field Instrument will capture a field of view at least 100 times larger than that of the Hubble Space Telescope, enabling the observatory to capture more of the sky with less observing time. A single image from the Roman Space Telescope will hold the equivalent detail of 100 pictures from Hubble, functioning as Hubble’s wide-eyed cousin while matching its sensitivity. Over the course of the primary mission lifetime, the instrument will measure light from one billion galaxies.
Exoplanet Surveys and Extended Mission Timeline
In addition to galaxy surveys, the Roman Space Telescope will perform a microlensing survey of the inner Milky Way designed to discover more than 1,000 exoplanets, according to NASA Science. Meanwhile, the Coronagraph Instrument technology demonstration will perform high-contrast imaging and spectroscopy of individual nearby exoplanets. The mission has also received a significant operational boost regarding its lifespan. According to Ars Technica and Universe Today, the Nancy Grace Roman Space Telescope’s mission has been extended, with the spacecraft carrying enough propellant to support operations for 22 years—double NASA’s original expectations and an increase from the initial 10-year outlook. The observatory has a baseline primary mission lifetime of 5 years, with a potential 5-year extended mission initially mapped out by NASA Science before the propellant capacity findings extended the operational outlook further.
