IRIS Launch Set for Thursday
Technicians
and engineers at Vandenberg Air Force Base in California mate the
Pegasus XL rocket with the Interface Region Imaging Spectrograph, or
IRIS, solar observatory to the Orbital Sciences L-1011 carrier aircraft.
The launch of NASA's IRIS mission has been delayed one day to 10:27
p.m. EDT on Thursday, June 27. Live NASA Television launch coverage
begins at 9 p.m.
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. The IRIS mission will
observe how solar material moves, gathers energy and heats up as it
travels through a largely unexplored region of the solar atmosphere. The
interface region, located between the sun's visible surface and upper
atmosphere, is where most of the sun's ultraviolet emission is
generated. These emissions impact the near-Earth space environment and
Earth's climate.
