Today at 11:14 pm PDT (2:14 pm EDT) the IRIS Lockheed Martin instrument team successfully opened the door on NASA's Interface Region Imaging Spectrograph, which launched June 27, 2013, aboard a Pegasus XL rocket from Vandenberg Air Force Base, Calif.

A 60-day check out period began at launch. The first 30 days, which ends July 27, consists of tests and spacecraft system checks. The team will use the remaining 30 days for initial observing runs to fine tune instrument observations. If all is nominal, the team plans to begin normal science mode by August 26.

All data will be available to scientists and the public as soon as the mission begins science operations. The team is looking forward to receiving high-resolution images and spectra soon after first light.
