Scientific paper

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 coronography, it will be capable of observing predicted primeval objects down to flux levels of a few nJy (10 σ) at 2 μm. Operated like the Hubble telescope from the Space Telescope Science Institute in Baltimore, it will be available for general observers by proposals, to be solicited a year before launch. It has a required lifetime of 5 years and fuel for 10.
