NASA's Roman Space Telescope kicks off a sweeping cosmic survey.
TL;DR Summary
NASA launches the Nancy Grace Roman Space Telescope, a wide-field observatory with a 2.4-meter mirror and a 300-megapixel camera designed to map about 12% of the sky—100 times the field of view of Hubble—surveying billions of galaxies, thousands of exoplanets, and the universe's dark energy and dark matter. It will downlink roughly 1.4 terabytes of data per day (about 20 petabytes over five years) from a Sun-Earth L2 orbit, with a coronagraph for direct exoplanet imaging and first science images expected by year-end.
