The James Webb Space Telescope Mission

AIP Conference Proceedings, 2010
The James Webb Space Telescope, planned to extend the scientific discoveries of the Hubble Space Telescope, will be a powerful observational tool for the investigation of the first stars and galaxies. With a 6.5‐m hexagonal mirror cooled to ∼40 K, and an instrument package covering 0.6 to 28 μm with imaging, spectroscopy with R up to ∼3000, and ...

Commissioning the James Webb Space Telescope Observatory

Space Telescopes and Instrumentation 2020: Optical, Infrared, and Millimeter Wave, 2020
The James Webb Space Telescope (JWST) is going through final integration and testing and is planned to launch in 2021. The last remaining optical challenge for JWST is to fully align the observatory in flight to meet the optical requirements but this effort involves many system considerations to do this safely and efficiently and the entire effort ...

Space telescopes after the James Webb Space Telescope

SPIE Proceedings, 2004
Following the use of the James Webb Space Telescope (JWST), there will be a need for space telescopes or interferometers of increasing size and, later, of increasing aperture. Looking ahead to the known problems of the next decade allows a modest extrapolation from JWST to address the currently interesting science.
