NASA SCHEDULES NEWS MEDIA EVENTS FOR IRIS LAUNCH

CAPE CANAVERAL, Fla. -- 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 Corp.
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.

MEDIA ACCREDITATION

News media desiring accreditation for the prelaunch and launch
activities for IRIS should fax their requests on news organization
letterhead to:

2nd Lt. Kaylee Ausbun
30th Space Wing Public Affairs Office
Vandenberg Air Force Base, Calif.
Telephone: 805-606-3595
Fax: 805-606-4571
Email: kaylee.ausbun@us.af.mil
