Watch On <\/a><\/p>\n NASA’s newest space telescope is ready for its moment on stage \u200a\u2014\u200a and soon, in space.<\/p>\n The agency will unveil the Nancy Grace Roman Space Telescope<\/a> on Tuesday (April 21) at 4 p.m. EDT (2100 GMT), and you can watch the event live here at Space.com courtesy of NASA.<\/p>\n Read more for details on what to expect at the news conference, as well as what’s next for the mission launching as soon as this fall.<\/p>\n You may like<\/p>\n \n NASA’s Nancy Grace Roman Space Telescope stands fully assembled, following the integration of its two major segments, in the clean room at the agency’s Goddard Space Flight Center in Greenbelt, Maryland. (Image credit: NASA\/Jolearra Tshiteya)News conference and launch<\/p>\n According to NASA<\/a>, briefing participants, who will discuss the telescope’s progress and science plans, include:<\/p>\n NASA Administrator Jared IsaacmanNicky Fox, associate administrator, science mission directorateJamie Dunn, Roman telescope project managerJulie McEnery, Roman telescope senior project scientist.<\/p>\n The news conference will take place at NASA’s Goddard Spaceflight Center <\/a>in Greenbelt, Maryland, where Roman was built.<\/p>\n Roman is almost finished its prelaunch testing at Goddard ahead of its last big journey on Earth \u2014 a shipment to NASA’s Kennedy Space Center<\/a> in Florida, where the telescope will launch aboard SpaceX<\/a> Falcon Heavy between autumn 2026 and May 2027.<\/p>\n What is Roman?<\/p>\n Roman, estimated to cost more than $4 billion, is a big survey telescope designed to show astronomers more about how the universe formed and evolved.<\/p>\n Roman has a telescope mirror similar in size to the famed Hubble Space Telescope<\/a>, at 8 feet or 2.4 meters. But the key difference is scope: Hubble narrows in on fine details, while Roman aims to survey the sky with a field of view 100 times larger than Hubble’s.<\/p>\n Looking at large-scale structure of galaxies and stars is part of Roman’s work, as it seeks to answer questions about how the universe formed, evolved and expanded with investigations concerning dark matter<\/a> and dark energy<\/a>.<\/p>\n Searching for exoplanets<\/p>\n Roman will also do a “Galactic Bulge Time-Domain Survey” to look at the central bulge of stars<\/a> of the Milky Way galaxy<\/a>. Investigators will mostly be looking for exoplanets<\/a>, using a technique called gravitational lensing<\/a>.<\/p>\n![\"inside](\"https:\/\/www.newsbeep.com\/nz\/wp-content\/uploads\/2026\/04\/ziu2wrUcA74BrYYY9rVBvF.jpg\")
