# NASA's new space telescope set to unravel universe's mysteries Nancy Grace Roman Telescope offers 100 times wider field of view than Hubble - **Source:** [Ars Technica - All content](https://brifing.si/source/b728770c-8dda-457a-8986-84879c9fc42c) - **Published:** 2026-08-31 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/35ac0df1-bc00-4397-ad45-efca628b9c29 ## Historic launch accomplished NASA's $4.3 billion Nancy Grace Roman Space Telescope successfully launched from Kennedy Space Center in Florida. Equipped with a refurbished spy satellite mirror and 300-megapixel camera, the telescope will provide 100 times wider field of view than Hubble. A SpaceX Falcon Heavy rocket carried the observatory to space. ## Completed ahead of schedule Unlike the James Webb Telescope, Roman reached the launch pad nine months early. NASA administrator Jared Isaacman highlighted the project's success in meeting budget and timeline goals. The telescope launched before its May 2027 target date. ## Massive engineering feat Fully fueled, the telescope weighed 9 metric tons, pushing Falcon Heavy's payload capacity. Its 2.4-meter primary mirror matches Hubble's size. The telescope was built using repurposed equipment from US spy satellite programs. ## Unique orbital position The telescope will settle at Lagrange Point L2, 1.5 million km from Earth. This gravitationally stable position offers uninterrupted observation opportunities. The journey and calibration process is expected to take three months. ## Revolutionizing astronomy Roman will survey 12% of the sky - 120 times more than Hubble covered in 36 years. NASA science director Nicky Fox calls it the 'Swiss Army knife of astronomy.' It can perform in one month observations that would take Hubble a century. ## Hunting dark matter A primary mission objective is studying dark energy, believed to constitute 70% of the universe. Roman will test the Standard Model of cosmology and help unravel dark matter mysteries. Project scientist Julie McEnery notes they're looking for evidence that might disprove current models. ## Unprecedented discovery potential During its mission, Roman is expected to discover tens of thousands of new planets, billions of galaxies, and tens of billions of stars. Just one month of observation could detect half the stars in our Milky Way, creating the most comprehensive astronomical catalog to date. ## From spy tech to science The telescope's primary mirror came from canceled US spy satellite programs. Of two telescopes transferred to NASA in 2012, one was allocated to the Roman project. Engineers reconfigured the mirror's optical design for space conditions. ## A pioneer's legacy The telescope honors NASA's first chief astronomer, Nancy Grace Roman, who pioneered space telescopes and played a key role in Hubble's development. Retired in 1979 and deceased in 2018, Roman's name was assigned to this next-generation telescope in 2020. ## New era in space exploration The Nancy Grace Roman Telescope forms the second pillar of NASA's Great Observatories program alongside James Webb. Scientists predict it will revolutionize our understanding of the universe and potentially lead to discoveries of new physics laws. First scientific images are expected by year's end. ## Sources covering this story - https://arstechnica.com/space/2026/08/nasas-next-great-observatory-begins-mission-to-widen-our-view-of-the-universe/ — --- _Summary written by Brifing from the original reporting.
