Primary Mirror for NASA's Roman Space Telescope Completed
The Nancy Grace Roman Space Telescope's primary mirror, which will collect and focus light from cosmic objects near and far, has been completed. Using this mirror, Roman will capture stunning space vistas with a field of view 100 times greater than Hubble images.

"Achieving this milestone is very exciting," said Scott Smith, Roman telescope manager at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "Success relies on a team with each person doing their part, and it's especially true in our current challenging environment. Everyone plays a role in collecting that first image and answering inspiring questions."

Roman will peer through dust and across vast stretches of space and time to study the universe using infrared light, which human eyes can't see. The amount of detail these observations will reveal is directly related to the size of the telescope's mirror, since a larger surface gathers more light and measures finer features.

Roman's primary mirror is 7.9 feet (2.4 meters) across. While it's the same size as the Hubble Space Telescope's main mirror, it is less than one-fourth the weight. Roman's mirror weighs only 410 pounds (186 kilograms) thanks to major improvements in technology.

Это все-же скорее не новый Хаббл, а новый Спитцер, ибо будет работать в ИК-диапазоне. Если будет, конечно, так как у NASA стало уже традицией в каждом проекте бюджета предлагать его прикрыть.
