Excerpt:

Kepler is now 1. 5 million kilometers (930,000 miles) from Earth. At that distance it takes a total amount of 10 seconds for a command sent from Earth, traveling at the speed of light, to reach the spacecraft and for a reply to show up back at Earth. Flight controllers call this the "round-trip light time," and take this time delay into account when commanding the spacecraft. Scientists are analyzing the first calibration information accumulated when the spacecraft's photometer was placed as far away from the sun as possible, while engineers are remaining to collect information at various temperatures. With the cover still closed over the front of the telescope, a lot of components are a bit warmer than they will be when the cover is launched.

NASA's Uncanny Amazing Webb Mirrors | Redux

NASA's Uncanny Amazing Webb Mirrors

Excerpt:

The first two mirrors that will fly aboard NASA's James Webb Space Telescope arrived at NASA's Goddard Space Flight Center in Greenbelt, Md. on Sept. 17, 2012. In this photo , one of the two mirrors was being "uncanned" as the shipping canister it was delivered in was opened in NASA's giant clean room . There are a total of 18 mirror segments that comprise the Webb's big primary mirror. The mirrors were delivered from Ball Aerospace & Technologies Corp. of Boulder, Colo. who produced and packed them. The Webb telescope's mirrors will certainly permit the James Webb Space Telescope see farther away and further back in time to detect the light from the really first and most distant stars and galaxies. The Webb telescope has 21 mirrors, with 18 primary mirror segments interacting as one large 21. 3-foot (6. 5-meter) primary mirror.
