Infrared
astronomy is truly coming of age. Many of NASAs most important
and ambitious upcoming missions, including SOFIA, the Next Generation
Space Telescope, and Terrestrial Planet Finder, feature infrared
telescopes, so the stage is being set for infrared science to play
a leading role in the study of the universe for the coming decades.
The
next major infrared mission is the Space Infrared Telescope Facility
(SIRTF), a cryogenic space telescope set to launch in early 2003.
SIRTF was originally conceived to be the fourth and final installment
of NASAs Great Observatories, a fleet of space telescopes
designed to give astronomers a view of the universe across the entire
electromagnetic spectrum. With the Compton Gamma-Ray Observatory
having completed its mission, and with the other two Great Observatories
(Hubble and Chandra) still in place, SIRTF stands poised not just
to round out the program, but also to connect that program solidly
into NASAs new initiative, the search for humanitys
cosmic origins.
