WFIRST, shown here in an artist’s rendering, will carry a Wide Field Instrument to provide astronomers with Hubble-quality images covering large swaths of the sky, enabling several studies of cosmic evolution. Its Coronagraph Instrument will directly image exoplanets similar to those in our own solar system and make detailed measurements of the chemical makeup of their atmospheres.<\/p>\n

NASA\u2019s next flagship observatory, often described as a successor to the Hubble Space Telescope, is about to leave NASA\u2019s Goddard Space Flight Center in Maryland and head to Kennedy Space Center in Florida for final launch preparations ahead of a planned launch as early as September aboard a SpaceX Falcon Heavy rocket.<\/p>\n

In an announcement<\/a> on Monday, June1, NASA said that the recently completed Roman Space Telescope would travel aboard NASA\u2019s Pegasus barge, with its eventual lift-off planned for Launch Complex 39A.<\/p>\n

The journey marks the beginning of the final chapter before launch for a mission that could fundamentally change astronomers\u2019 understanding of both the universe and the planets that populate our galaxy.<\/p>\n

A New Era Beyond Hubble<\/p>\n

Named after NASA\u2019s first chief astronomer and the woman often called the \u201cMother of Hubble,\u201d the Roman Space Telescope combines a Hubble-sized 2.4-meter mirror with a field of view roughly 100 times larger than Hubble\u2019s.<\/p>\n

That unique combination will allow Roman to generate the first sweeping panoramic views of the universe, helping scientists investigate dark energy, study cosmic evolution and search for planets beyond our solar system.<\/p>\n

While Hubble has transformed astronomy with its deep, narrow observations of objects, Roman will be able to scan enormous regions of the sky, potentially revealing millions of previously unseen cosmic objects. A key goal for Roman will be to discover a new kind of exoplanet.<\/p>\n

Scientists expect the mission to identify around 100,000 new planets, a dramatic increase over the nearly 6,300 exoplanets discovered to date. Many of them will be small worlds in large orbits \u2014 a category of exoplanet that has so far eluded astronomers \u2014 and in regions of the Milky Way that astronomers have barely explored.<\/p>\n

\u201cOur galaxy is home to a variety of different environments, but when it comes to hunting for exoplanets, we\u2019ve really only explored one: our own neighborhood,\u201d said<\/a> Elisa Quintana, an exoplanet researcher at NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland, in late May. \u201cRoman will extend the search far enough to encompass other galactic habitats, which could help us learn how planet formation varies across different regions of the Milky Way.\u201d<\/p>\n

Roman will search for planets using both transit observations and gravitational microlensing, a technique capable of detecting worlds that are difficult or impossible to find using other methods. Scientists expect the mission to discover planets ranging from giant gas worlds to rocky planets similar in size to Earth and Mars.<\/p>\n

Roman vs Kepler vs Gaia<\/p>\n

Once in space, Roman is expected to become one of the most powerful astronomical survey instruments ever built. It\u2019s essentially a much more capable follow-up to NASA\u2019s Kepler mission, which surveyed 100,000 stars and found thousands of exoplanets from 2009 to 2018. \u201cRoman\u2019s galactic bulge survey will observe around 100 million stars and probe underexplored areas of our galaxy, which will provide a foundational dataset that will likewise revolutionize what we know about other worlds and our place in the universe,\u201d said Jorge Mart\u00ednez-Palomera, an astronomer at NASA Goddard, preparing for Roman\u2019s exoplanet data.<\/p>\n

Roman is also complementary to the European Space Agency\u2019s Gaia spacecraft, which, from 2013-2025, made three trillion observations of two billion stars in the Milky Way in visible light. Roman will detect infrared light to see beyond the stars, allowing astronomers to peer through the densest part of the galaxy for the first time.<\/p>\n

NASA’s Goddard Space Flight CenterFrom WFIRST To Roman<\/p>\n

Roman\u2019s journey to the launch pad has not been straightforward. Before being renamed in 2020, the mission was known as the Wide Field Infrared Survey Telescope (WFIRST). It faced an uncertain future when the Trump administration proposed canceling the project in its 2019 and 2020 budget requests.<\/p>\n

At the time, concerns centered on the mission\u2019s cost and NASA\u2019s focus on completing the James Webb Space Telescope. Congress ultimately rejected the proposed cancellation and continued funding development, preserving what many astronomers viewed as one of the agency\u2019s most important future science missions. JWST was successfully launched on Dec. 25, 2021.<\/p>\n

Expected to become one of the most productive astronomical observatories ever built, Roman could transform humanity\u2019s understanding of exoplanets, dark energy and the structure of the cosmos \u2014 and be just as iconic as Hubble was and still is.<\/p>\n
