"DLT, drop on my mark, 3, 2, 1 ....Pegasus is away, Pegasus is away."

The Pegasus missile launched from a NASA plane yesterday carried a new space telescope into orbit.

The Iris spacecraft, as it's called, will  be used to investigate the mysterious zone between the surface of the sun and its atmosphere.

Astronomers hope to learn how solar material moves, and just how the outer regions of the sun get so hot, more than 3.5 million degrees Fahrenheit.

Scientists say that knowledge could lead to better understanding of ultra-violet or UV radiation that affects Earth's climate.
