NASA’s next eye into the cosmos is due to leave our planet later this year. The agency says it’s targeting an early September launch for the Nancy Grace Roman Space Telescope. Roman (for short) has a field of view 100 times larger than Hubble’s.
The September date is the earliest possible launch for Roman. NASA says it will go up (aboard a SpaceX Falcon Heavy rocket) no later than May 2027.
The Nancy Grace Roman Space Telescope, named after NASA’s first chief astronomer and “mother” of Hubble, was introduced in 2016. (Back then, it was known as the Wide Field Infrared Survey Telescope, or WFIRST.) The telescope’s mirror is roughly the same size as Hubble’s, but it can capture sections of the sky at least 100 times larger than its predecessor.

“Roman will work in tandem with NASA observatories such as the James Webb Space Telescope and Chandra X-ray Observatory, which are designed to zoom in on rare transient objects once they’ve been identified, but seldom if ever discover them,” Julie McEnery, Roman’s senior project scientist, said in 2023. “Roman’s much larger field of view will reveal many such objects that were previously unknown. And since we’ve never had an observatory like this scanning the cosmos before, we could even find entirely new classes of objects and events.”
After leaving our atmosphere, Roman will set course for a vantage point nearly 1 million miles from Earth. There, it will rely on a pair of instruments to study space. The first is a 300.8-megapixel camera that captures light from visible to near-infrared. There’s also a high-contrast coronagraph that will allow it to capture exoplanets that would otherwise be blocked by starlight.
Roman’s mission: “to settle essential questions in the areas of dark energy, exoplanets and astrophysics.” Despite decades of study, astronomers know surprisingly little about dark energy, which makes up about 68 percent of the universe’s contents. And while scientific discoveries are cool and all, you’ll be pleased to know that Roman is also sure to beam back more dazzling pictures of our cosmos.
