NASA\u2019s Nancy Grace Roman Space Telescope, named after NASA\u2019s first Chief of Astronomy. If all goes to plan, Roman will launch on Aug. 30 and begin creating the largest panoramic maps of the universe ever made \u2014 providing astronomers with a new roadmap for exploring everything from nearby exoplanets to the evolution of the cosmos.

NASA\u2019s next flagship space observatory is almost ready for launch. The Nancy Grace Roman Space Telescope<\/a> is scheduled to lift off aboard a SpaceX Falcon Heavy rocket from Kennedy Space Center in Florida from 7:26 a.m. EDT on Sunday, Aug. 30. Launching roughly nine months ahead of NASA\u2019s previous schedule, Roman is expected to become one of the most powerful astronomy missions ever built \u2014 not because it will see farther than the James Webb Space Telescope, but because it will see more of the universe at once. \u201cRoman is going to do things that currently are impossible,\u201d said Shawn Domagal-Goldman, director of NASA\u2019s Astrophysics Division, in a NASA press conference<\/a> on July 29. \u201cIt\u2019s going to launch \u2026 nine months in advance, and that of itself is an amazing feat.\u201d <\/p>\n Here are 10 things to know before launch.<\/p>\n 1. It\u2019s Named After The \u2018Mother Of Hubble\u2019<\/p>\n The telescope honors Dr. Nancy Grace Roman, NASA\u2019s first chief astronomer and one of the driving forces behind the agency\u2019s space astronomy program. Her vision of placing telescopes above Earth\u2019s atmosphere laid the foundation for NASA\u2019s fleet of observatories, including Hubble, Chandra, Spitzer, Webb and now Roman. \u201cDr. Roman was a brilliant astronomer \u2014 she realized how much power we would have if we could get telescopes up above Earth’s atmosphere, which otherwise gets in the way of our observations from the ground, and how it could complement the astronomy we can do from the ground,\u201d said Domagal-Goldman.<\/p>\n 2. Roman Doesn\u2019t Replace Hubble Or Webb<\/p>\n Instead, it complements them. Domagal-Goldman compares NASA\u2019s space telescopes to photographing a forest. Hubble and Webb can zoom in on individual trees, leaves and birds. Roman \u201cdoes both; it has that wide-angle view of the forest and the sharpness to see the birds and leaves on those trees.\u201d Instead of focusing on individual objects, Roman will reveal how those objects fit into the wider universe. The forest is the known universe, and those birds and trees are supernova, galaxies, planets and stars.<\/p>\n 3. It Will Map More Than Two Billion Galaxies<\/p>\n Roman\u2019s largest survey will chart more than two billion galaxies across cosmic time, creating the biggest panoramic maps of the universe ever produced from space. Its Wide Field Instrument combines the same 2.4-meter (7.9-foot) mirror size as Hubble with a field of view more than 100 times larger, allowing it to survey enormous areas of the sky far faster than any previous NASA space observatory.<\/p>\n 4. The Images Will Be Almost Impossible To Comprehend<\/p>\n Roman\u2019s biggest survey will produce images on a staggering scale. \u201cWe would need over half a million 4K TVs to fully display the single Roman image from our largest survey,\u201d said Julie McEnery, the mission\u2019s senior project scientist at NASA Goddard. \u201cThose TVs would cover 45 Manhattan city blocks, or fully cover El Capitan in Yosemite National Park.\u201d<\/p>\n 5. It Could Discover 100,000 New Planets<\/p>\n Roman will monitor hundreds of millions of stars in the Milky Way using gravitational microlensing and other techniques to search for exoplanets. Unlike Kepler and TESS, which excel at finding planets orbiting close to their stars, Roman will search for colder, more distant worlds similar to those in our own outer solar system. McEnery calls it \u201cthe largest census we\u2019ve ever done of planets outside our own solar system.\u201d<\/p>\n 6. It May Help Solve The Mystery Of Dark Energy<\/p>\n Astronomers still don\u2019t know why the universe\u2019s expansion is accelerating. By mapping billions of galaxies, measuring gravitational lensing and observing thousands of Type Ia supernovae, Roman will provide the most detailed measurements yet of dark energy and dark matter, helping scientists test whether today\u2019s standard model of cosmology is complete.<\/p>\n 7. It Will Find Things Astronomers Aren\u2019t Even Looking For<\/p>\n One reason astronomers are so excited is that Roman\u2019s enormous surveys are expected to reveal phenomena no one anticipated. \u201cRoman\u2019s vast reach will allow us to find the weird, the rare, and the unusual,\u201d said McEnery, pointing to isolated black holes, rogue planets and runaway supermassive black holes. \u201cWe\u2019ll redefine what it means to find a needle in a haystack.\u201d She added that the discoveries she\u2019s most excited about are the ones nobody can predict.<\/p>\n 8. Launch Is Only The Beginning<\/p>\n Although the Falcon Heavy launch is the headline event, Roman won\u2019t begin science immediately. After separation from the rocket, engineers will spend about 100 days deploying the observatory, testing its systems, aligning its optics and calibrating its instruments before regular science operations begin. \u201cWe\u2019ve practiced this over and over and over again,\u201d said integration and test scientist Jeremy Perkins, who will help oversee commissioning after launch.<\/p>\n 9. It Will Return An Enormous Amount Of Data<\/p>\n Roman is expected to transmit around a terabyte of science data to Earth every day. Perkins compares that to \u201cstreaming a million songs from a million miles from Earth.\u201d That torrent of observations will eventually require machine learning and advanced computing to help astronomers identify the most interesting discoveries hidden within the mission\u2019s vast datasets.<\/p>\n 10. Nobody Knows What Roman\u2019s Biggest Discovery Will Be<\/p>\n Like Hubble before it, Roman is expected to answer questions astronomers haven\u2019t even thought to ask yet. \u201cWhat makes me most excited about Roman is the discovery potential,\u201d McEnery said. \u201cI very much hope \u2014 and in fact expect \u2014 that the most exciting things from Roman will be a surprise.\u201d<\/p>\n After years of development and an unusually early finish for a flagship NASA mission, the countdown is almost over. If all goes to plan, Roman will launch on Aug. 30 and begin creating the largest panoramic maps of the universe ever made \u2014 providing astronomers with a new roadmap for exploring everything from nearby exoplanets to the evolution of the cosmos.<\/p>\n Wishing you clear skies and wide eyes.<\/p>\n","protected":false},"excerpt":{"rendered":"NASA\u2019s Nancy Grace Roman Space Telescope, named after NASA\u2019s first Chief of Astronomy.
