NASA's newest space telescope launches on a quest to explore the hidden universe
The $4.3 billion observatory will survey hundreds of millions of stars and galaxies and search for clues to dark energy and dark matter.
- On Sunday, August 30, 2026, NASA launched the $4.3 billion Nancy Grace Roman Space Telescope from Kennedy Space Center aboard a SpaceX Falcon Heavy rocket. The observatory separated from the rocket after 31 minutes, beginning its journey toward the Sun-Earth L2 Lagrange point.
- NASA repurposed a 2.4-meter mirror from a National Reconnaissance Office spy satellite, donated in 2012, for this mission named after Nancy Grace Roman, the agency's first chief astronomer and key architect of the Hubble Space Telescope.
- Roman's 300-megapixel Wide Field Instrument captures a field of view 100 times larger than Hubble's, enabling the observatory to survey the sky 1,000 times faster. This capability transforms Roman into an unprecedented data-gathering platform.
- Scientists expect Roman to investigate dark matter, dark energy, and over 100,000 exoplanets during its mission. NASA plans to release first images in early 2027 following a three-month commissioning period.
- The primary mission lasts five years, though Roman carries enough hydrazine fuel to potentially extend operations to ten. Engineers designed the spacecraft to be refuelable in space, though future on-orbit servicing remains uncertain.

NASA launches $4B Roman Space Telescope
NASA began a new mission to probe some of the biggest mysteries in astrophysics and cosmology with the launch on Sunday of the U.S. space agency's new flagship astronomical observatory, a repurposed spy satellite that will capture panoramic views of the cosmos.
When will we see the first images from NASA’s Roman Space Telescope?
The telescope is expected to reach its destination in about three months, with engineers then spending several months testing its instruments.
SpaceX launches NASA’s newest crown-jewel telescope, which will look for 'the weird, the rare and the unusual' — including dark matter and energy
“It’s going to find thousands of supernovae, tens of thousands of planets, billions of galaxies and tens of billions of stars.”
NASA launched its Roman telescope, which is expected to provide answers to the mysteries of physics that represent matter and dark energy.
