NASA's new science mission

A small satellite called AIM (Aeronomy of Ice in the Mesosphere) went into space today on a Pegasus booster. The spacecraft will look at the highest and strangest clouds known to science - the mysterious noctilucent clouds, glowing nighttime phenomena which drift at altitudes of 50 miles. The booster carried Virginia Tech logos in memory of the people killed in the mass shooting at the university last week.
