Description

The Webb Space Telescope's orbit will place it out of reach of astronauts, so it's important to have perfect control of the telescope from Earth. At Northrop Grumman, engineers are testing the telescope's responses to controllers and simulating the conditions it'll face in space. "Behind the Webb" is a recurring video series from HubbleSite, home of the Hubble Space Telescope and the upcoming Webb Space Telescope. Join host Mary Estacion as she goes behind the scenes to watch the construction and testing of the parts that will make Webb the world's most powerful infrared telescope.
