IRIS Briefings and Events Coverage
June 11, 2013
 

NASA's Interface Region Imaging Spectrograph (IRIS) mission is scheduled to launch Wednesday, June 26, from Vandenberg Air Force Base in California on an Orbital Sciences Corporation Pegasus XL rocket. Launch is targeted for 7:27 p.m. PDT (10:27 p.m. EDT) in the middle of a five-minute launch window.

The drop of the Pegasus from Orbital's L-1011 carrier aircraft will occur over the Pacific Ocean at an altitude of 39,000 feet, approximately 100 miles northwest of Vandenberg off the central coast of California, south of Big Sur. The Pegasus will be deployed from the L-1011 on a southerly launch azimuth of 198.6 degrees. The rocket will place IRIS into a sun-synchronous polar orbit of 387.5 by 418.7 miles (620 by 670 km) at an inclination of 97.89 degrees.

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 interface region also is where most of the sun's ultraviolet emission is generated that impacts the near-Earth space environment and Earth's climate.

Following the two briefings, news media will be taken to the Vandenberg Air Force Base runway to see the Orbital Sciences L-1011 carrier aircraft with the Pegasus/IRIS rocket ready for launch. Spokespersons will be on hand to answer questions and for interviews. News media will be permitted to board the aircraft.

News Media Coverage of IRIS Events
Tuesday, June 25: News media desiring to cover the IRIS prelaunch news conference and mission science briefing should meet at the south gate of Vandenberg Air Force Base on California State Road 246 west of Lompoc at 11:30 a.m. PDT for an escort to the NASA Vandenberg Resident Office in Building 840. After the briefings end at approximately 1:30 p.m., media who desire to see the Pegasus with IRIS and tour Orbital's L-1011 "Stargazer" carrier aircraft will be taken to the Vandenberg Air Force Base runway.

Wednesday, June 26: News media representatives should meet at the Vandenberg main gate at 5:45 p.m. PDT to be escorted to the Vandenberg Air Force Base runway to view the departure of the L-1011 aircraft at 6:27 p.m. Media then will be taken to the second floor conference room of the NASA Resident Office in Building 840 on South Vandenberg Air Force Base. From there, media may follow the flight and launch of Pegasus/IRIS.

A post-launch news conference will not be held.
