IRIS Mission Preps Move Ahead
Tue, 30 Oct 2012 01:56:23 PM UTC

Preparations to launch NASA's IRIS mission aboard an Orbital Sciences Pegasus XL rocket continue on pace for a launch in the spring from Vandenberg Air Force Base, Calif. Telemetry system testing with the launch vehicle has been completed and the guidance and navigation system is being installed this week. Also, technicians are installing the springs associated with the stage 1 separation mechanism. The first launch vehicle flight simulation is currently planned to occur in early November.

We had a good Vehicle Verification test late last week - spun the fins, rocked & tilted the stage 2 & 3 nozzles, and fired the RCS jets. The test schedule is kind of fluid right now because of minor snags; funny that the previous post of a NASA RSS feed went out - I just now canceled my travel plans for that test! We'll do it later in the month. The range confirmed Feb 27, but there may be some spacecraft delays, so who knows?

I really hate the thought of this being the last Pegasus, potentially. It's a good little rocket. I hope we can throw some more business Orbital's - and Pegasus' - way.

Orbital & NASA engineering performed a vehicle inspection last week and found the rocket to be in very clean shape with just a few minor items requiring additional attention. We'll resume testing next month. Then we just need a satellite....not sure when it's due to arrive.

Antenna Tests Scheduled for Pegasus
Tue, 26 Feb 2013 04:40:35 PM UTC

Technicians will test antennas Feb. 27 on the Orbital Sciences Pegasus XL rocket that will carry NASA's IRIS spacecraft into orbit this Spring. Launching from California's coast, the Pegasus will communicate with systems of the Air Force's Western Range during its ascent into orbit. A second flight simulation for the mission is planned for March 6. Teams are also reviewing the spacecraft processing activities ahead of the arrival of IRIS in April.

Pegasus Preps Continue Smoothly at Vandenberg
Tue, 05 Mar 2013 06:56:25 PM UTC

Technicians are working smoothly through preparations to launch an Orbital Sciences Pegasus XL rocket from Vandenberg Air Force Base, Calif., later this year on NASA's IRIS mission. Stages 2 and 3 of the launch vehicle have now been integrated. Orbital will conduct its second Pegasus flight simulation tomorrow.

VANDENBERG AIR FORCE BASE, Calif.
At Vandenberg Air Force Base in California, the three stages of the Orbital Sciences Corp. Pegasus XL rocket have been mated in preparation for the launch the Interface Region Imaging Spectrograph, or IRIS, spacecraft. Scheduled for launch from Vandenberg Air Force Base no earlier than April 29, 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 sunís 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.

Launch date is still very much up in the air. It may actually move to the left a bit.

Pegasus Fairing Arrives for IRIS
Tue, 26 Mar 2013 01:13:53 PM UTC

Technicians inspected the payload fairing that arrived at Vandenberg Air Force Base March 22.  Initial electrical testing is now under way to ensure it will operate as planned during the launch of NASAís IRIS spacecraft on the Orbital Sciences Pegasus rocket. The two-piece fairing will protect the spacecraft from atmospheric heating during launch.

Pegasus Rocket in Prelaunch Testing for IRIS Mission
Mon, 08 Apr 2013 08:24:20 PM UTC

The Orbital Sciences Pegasus XL rocket slated to launch NASA's IRIS spacecraft is undergoing power and telemetry system testing this week at Vandenberg Air Force Base in California. The rocket's payload fairing has been inspected and cleaned, and the initial electrical system test is complete. The IRIS spacecraft is scheduled to arrive at Vandenberg on April 16 to begin preparations for launch.

RELEASE: 10-13

NASA'S NEWEST SOLAR SATELLITE ARRIVES AT VANDENBERG AFB FOR LAUNCH

GREENBELT, Md. -- NASA's Interface Region Imaging Spectrograph (IRIS)
satellite arrived at Vandenberg Air Force Base in California on
Tuesday, April 16, to begin its final preparations for launch,
currently scheduled no earlier than May 28. IRIS will improve our
understanding of how heat and energy move through the deepest levels
of the sun's atmosphere, thereby increasing our ability to forecast
space weather.

Following final checkouts, the IRIS spacecraft will be placed inside
an Orbital Sciences Pegasus rocket. Deployment of the Pegasus from
the L-1011 carrier aircraft is targeted for 7:27 p.m. PDT at an
altitude of 39,000 feet at a location over the Pacific Ocean about
100 miles northwest of Vandenberg AFB off the central coast of
California south of Big Sur.

"IRIS will contribute significantly to our understanding of the
interface region between the sun's photosphere and corona," said Joe
Davila, IRIS mission scientist at NASA's Goddard Space Flight Center
in Greenbelt, Md. "This region is crucial for understanding how the
corona gets so hot."

IRIS carries a single instrument, a multichannel imaging spectrograph
with an ultraviolet (UV) telescope that will help scientists better
understand the physical processes in the sun's interface region.

"With the high-resolution images from IRIS, scientists will be able to
use advanced computer models to unravel how matter, light and energy
move from the sun's 6,000 Kelvin surface to its million Kelvin
corona," said Eric Ianson, IRIS mission manager at NASA Goddard.
"Scientists will be able to combine data from NASA's IRIS and Solar
Dynamics Observatory and the NASA/JAXA Hinode missions to obtain a
more comprehensive understanding of the sun's atmosphere."

IRIS is a NASA Small Explorer mission. The program provides frequent
flight opportunities for world-class scientific investigations from
space using innovative, streamlined and efficient management
approaches within the heliophysics and astrophysics areas.

NASA's Launch Services Program at Kennedy Space Center, Fla., is
responsible for launch management. Lockheed Martin's Advanced
Technology Center Solar and Astrophysics Laboratory in Palo Alto,
Calif., designed and built the IRIS spacecraft and instrument. NASA's
Ames Research Center in Moffett Field, Calif., is responsible for
mission operations and ground data systems.
