A NASA mission aimed at surveying black holes and supernovae, among other things, launched successfully today at noon ET from beneath the belly of a wide-body jet flying approximately 40,000 feet above a darkened Pacific Ocean.
The 772-pound NuSTAR X-ray observatory was carried into an equatorial orbit about 400 miles above the Earth by a Pegasus rocket, which fired its three-stage motor for 13 minutes after being dropped by the L-1011 jet.
