It’s been more than 36 years since NASA sent its Hubble Space Telescope into low-Earth orbit, and nearly five years since the agency’s James Webb Space Telescope started to circle the sun. Now a new, even more advanced hunk of astronomical hardware is set to follow its two pioneering predecessors into the cosmos: the Nancy Grace Roman Space Telescope. After more than a decade in development, the Roman Space Telescope will launch at 7:20 a.m. on Aug. 30 from NASA’s Kennedy Space Center in Florida — eight months ahead of schedule. “We’re going to find one-in-a-million things over and over and over again,” Jeremy Perkins, a Roman Telescope scientist at NASA’s Goddard Space Flight Center, recently predicted. To understand why the Roman Space Telescope matters, you first have to understand how it’s different.
