NASA's next "great observatory" begins mission to widen our view of the Universe

Key Points:

• NASA launched the $4.3 billion Nancy Grace Roman Space Telescope on June 25, 2023, from Kennedy Space Center using a SpaceX Falcon Heavy rocket, aiming to study dark energy, dark matter, and exoplanets with a 300-megapixel camera and a wide field of view 100 times larger than Hubble's.
• The telescope, named after NASA’s first chief astronomer Nancy Grace Roman, uses a refurbished 2.4-meter primary mirror originally built for a spy satellite, enabling it to survey 12% of the sky at speeds about 1,000 times faster than Hubble and generate unprecedented amounts of data.
• Roman will operate near the Sun-Earth L2 Lagrange point, about 1.5 million kilometers from Earth, and is equipped with two instruments: a Wide Field Instrument for large-scale cosmic surveys and a coronagraph for directly imaging exoplanets with much higher sensitivity than previous telescopes.
• Over its planned five-year mission, Roman is expected to discover tens of thousands of new planets, billions of galaxies, and thousands of supernovae, producing 20 petabytes of data that will be accessible via a cloud-based platform for global scientific analysis.
• The mission aims to provide new insights into the Universe’s structure and evolution, potentially challenging the current Standard Model by revealing the nature of dark energy and dark matter, and creating 3D movies of galactic phenomena never before observed.
