NASA launches satellite to study how sun’s atmosphere is energized

WASHINGTON -  NASA launched a Region Imaging Spectrograph (IRIS) spacecraft on Wednesday at 7:27 p.m. PDT (10:27 p.m. EDT) from Vandenberg Air Force Base, California, that would help in studying how sun’s atmosphere is energized.

The mission to study the solar atmosphere was placed in orbit by an Orbital Sciences Corporation Pegasus XL rocket.

NASA’s associate administrator for science in Washington, John Grunsfeld said that they were thrilled to add IRIS to the suite of NASA missions studying the sun.

He explained that IRIS would help scientists understand the mysterious and energetic interface between the surface and corona of the sun.

IRIS is a NASA 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. These emissions impact the near-Earth space environment and Earth’s climate.

The Pegasus XL carrying IRIS was deployed from an Orbital L-1011 carrier aircraft over the Pacific Ocean at an altitude of 39,000 feet, off the central coast of California about 100 miles northwest of Vandenberg. The rocket placed IRIS into a sun-synchronous polar orbit that will allow it to make almost continuous solar observations during its two-year mission.

The L-1011 took off from Vandenberg at 6:30 p.m. PDT and flew to the drop point over the Pacific Ocean, where the aircraft released the Pegasus XL from beneath its belly. The first stage ignited five seconds later to carry IRIS into space. IRIS successfully separated from the third stage of the Pegasus rocket at 7:40 p.m. At 8:05 p.m., the IRIS team confirmed the spacecraft had successfully deployed its solar arrays, has power and has acquired the sun, indications that all systems are operating as expected.

NASA’s Explorer Program at Goddard Space Flight Center in Greenbelt, Md., provides overall management of the IRIS mission. The principal investigator institution is Lockheed Martin Space Systems Advanced Technology Center.
