View Full Version : Discussion: SIRTF Successfully Focused

2003-Oct-14, 06:37 PM
SUMMARY: NASA’s recently launched Space Infrared Telescope Facility (SIRTF) passed an important milestone this week when it was successfully focused. The fourth, and last, of NASA’s great observatory has been in space since it was launched on August 25, and since then, it’s been slowly cooling down. The telescope is now only five degrees above Absolute Zero – this will let it pick up the faint infrared emissions from distant objects in space without seeing its own heat. The observatory will eventually reveal previously unseen objects obscured by gas and dust.
