Webb Telescope Mirrors Arrive at NASA Goddard

NASA image release April 13, 2011 An engineer examines the Webb telescope primary mirror Engineering Design Unit segment in the clean room at NASA's Goddard Space Flight Center, Greenbelt, Md. It takes two unique types of mirrors working together to see farther back in time and space than ever before, and engineers at NASA's Goddard Space Flight Center have just received one of each type. Primary and Secondary Mirror Engineering Design Units (EDUs) have recently arrived at NASA's Goddard Space Flight Center in Greenbelt, Md. from Northrop Grumman Aerospace Systems in Redondo Beach, Calif. and are undergoing examination and testing. When used on the James Webb Space Telescope those two types of mirrors will allow scientists to make those observations. "The Primary mirror EDU will be used next year to check out optical test equipment developed by Goddard and slated to be used to test the full Flight Primary mirror," said Lee Feinberg, the Optical Telescope Element Manager for the Webb telescope at NASA Goddard. "Following that, the primary and secondary EDU's will actually be assembled onto the Pathfinder telescope. The Pathfinder telescope includes two primary mirror segments (one being the Primary EDU) and the Secondary EDU and allows us to check out all of the assembly and test procedures (that occur both at Goddard and testing at Johnson Space Center, Houston, Texas) well in advance of the flight telescope assembly and test."

Webb Telescope Flight Mirrors Delivered to NASA

Credit: NASA/Chris Gunn ----- The first two of the 18 primary mirrors to fly aboard NASA’s James Webb Space Telescope arrived at NASA’s Goddard Space Flight Center in Greenbelt, Md. The mirrors are going through receiving and inspection and will then be stored in the Goddard cleanroom until engineers are ready to assemble them onto the telescope's backplane structure that will support them. Ball Aerospace, Boulder, Colo., under contract to Northrop Grumman, is responsible for the Webb’s optical technology and lightweight mirror system. On September 17, 2012, Ball Aerospace shipped the first two mirrors in custom containers designed specifically for the multiple trips the mirrors made through eight U.S. states while completing their manufacturing. The remaining 16 mirrors will make their way from Ball Aerospace to Goddard over the next 12 months as they await telescope integration in 2015.

NASA Now Has Half of all Webb Telescope's Primary Flight Mirrors

Three primary Webb telescope mirror segments sit in shipping cannisters and await opening. A mechanical integration engineer and technicians vent and prepare the mirror canisters for inspection. The mirrors have arrived at their new home at NASA, where they will be residing at the giant cleanroom at Goddard for a while as technicians check them out. Previously on Sept. 17, 2012, two other primary mirror segments arrived at Goddard and are currently being stored in the center's giant clean room.
