Return to Main TOPS

The Space InfraRed Telescope Facility, SIRTF, is the last of NASA's Great Observatories. It will be a cryogenically cooled space observatory. The telescope will have a 0.85m mirror which will operate in the 3-180 micron region for spectroscopy and imaging. It will carry out a mix of surveys and focused general observer programs.

Mission Timeline

  • 2001 - Launch
  • 2.5 year lifetime

IRTF Mission Support

  • Essential support for target selection
  • Complementary near-ir measurements
  • Temporal coverage of variable objects
  • Accurate thermal information to be able to interpre data on protoplanetary disks
  • For Brown dwarfs - need 1-5um spectra which SIRTF does not have
