James Webb Space Telescope

The next big space telescope is named in honor of James Webb, a former head of NASA who oversaw the Mercury and Gemini missions that prepared the agency for the Apollo Moon flights. It will observe the universe at infrared wavelengths, and will be deployed one million miles from Earth. That location will shield it from the warmth of Earth, which produces a lot of infrared energy.
