'The possibilities are truly breathtaking': NASA's Roman Space Telescope will take better images and last longer than experts predicted
NASA's Nancy Grace Roman Space Telescope is nearing its final destination more than 1 million miles (1.6 million kilometers) from Earth, where it will soon scour the universe for a host of cosmological treasures, including an estimated 100,000 new alien worlds.
Key points
- Roman is NASA's latest flagship space telescope, following in the footsteps of iconic observatories like the Hubble Space Telescope and the James Webb Space Telescope (JWST).
- Extended lifespan Shortly after Roman arrived in space on board a SpaceX Falcon Heavy rocket that lifted off from NASA's Kennedy Space Center in Florida, mission scientists conducted two major burns, or engine firings, which gave the spacecraft enough momentum to escape Earth's orbit and make the journey to L2.
- So far, this "commissioning process" has gone off without a hitch, and by the time Roman arrives in less than two weeks, it should be ready to snap its first in-depth images of the cosmos.
But even before its mission truly begins, recent developments suggest the state-of-the-art spacecraft could take better images than — and remain operational for more than twice as long as — initially expected, further delighting already-excited astronomers.
Additional details
- Second, after remotely adjusting the telescope's mirror, researchers discovered it should be capable of snapping images with around 30% greater detail than engineers predicted.
- "Since Roman's [weight] was lower than we budgeted for, we were able to fill the propellant tanks to their capacity rather than only filling them as much as we needed," Alison Rao, the Roman propulsion lead at NASA Goddard, said in the statement.
- (Image credit: SpaceX via NASA) Thanks to a combination of "exquisite planning by our orbital dynamics team" and "brilliant execution by the operations team," these burns were so precise that each one saved up to four years' worth of fuel, Jamie Dunn, director of NASA's Goddard Space Flight Center in Greenbelt, Maryland, said in a Sept.
- The team that designed, launched and remotely commissioned the orbital observatory has "done an amazing job" and "their work has ensured that Roman is more than up to the task," Kerins said.
- There, Roman will join several other important spacecraft, including JWST and the European Space Agency's Euclid telescope.
