Preparing NASA's Next Solar Satellite for Launch
Orbital Sciences team members move the second half of the payload fairing before it is placed over NASA's IRIS (Interface Region Imaging Spectrograph) spacecraft. The fairing connects to the nose of the Orbital Sciences Pegasus XL rocket that will lift the solar observatory into orbit. The work is taking place in a hangar at Vandenberg Air Force Base, where IRIS is being prepared for launch on a Pegasus XL rocket.Scheduled for launch from Vandenberg on June 26, 2013, IRIS will open a new window of discovery by tracing the flow of energy and plasma through the chromospheres and transition region into the sun's corona using spectrometry and imaging. IRIS fills a crucial gap in our ability to advance studies of the sun-to-Earth connection by tracing the flow of energy and plasma through the foundation of the corona and the region around the sun known as the heliosphere.

NASA Schedules Media Events and Coverage for New Solar Mission Launch
WASHINGTON
-- NASA's Interface Region Imaging Spectrograph (IRIS) mission is
scheduled to launch at 7:27 p.m. PDT (10:27 p.m. EDT) Wednesday, June
26, from Vandenberg Air Force Base in California.
Launch on an Orbital Sciences Corporation Pegasus XL rocket is targeted for the middle of a five-minute launch window. Live NASA Television coverage of the launch begins at 6 p.m. PDT (9 p.m. EDT). NASA TV also will air an IRIS prelaunch news conference and science briefing beginning at noon PDT (3 p.m. EDT) on Tuesday, June 25.
IRIS is a NASA Small Explorer Mission to observe how solar material moves, gathers energy and heats up as it travels through a little-understood region in the sun's lower atmosphere. This interface region between the sun's photosphere and corona powers its dynamic million-degree atmosphere and drives the solar wind.
The drop of the air-launched Pegasus from Orbital's L-1011 carrier aircraft will occur over the Pacific Ocean at an altitude of 39,000 feet, about 100 miles northwest of Vandenberg off the central coast of California, south of Big Sur.
The IRIS News Center at Kennedy's Vandenberg Resident Office will be staffed starting Monday, June 24 and may be reached between 8 a.m. and 4:30 p.m. at 805-605-3051.

NASA also will host a Google+ Hangout at 1:30 p.m. EDT June 25, on the IRIS mission. Social media followers may submit questions on Twitter and Google+ in advance and during the event using the hashtag #askNASA.
Before the hangout begins, NASA will open a thread on its Facebook page where questions may be posted. The hangout can be viewed live on NASA's Google+ page, the NASA Television YouTube channel or NASA TV. For more information and to join the hangout, visit:
Extensive prelaunch and launch day coverage of the IRIS spacecraft will be available on NASA's home page at:
