NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) spacecraft is scheduled for launch this coming Wednesday 13 June 2012, after being postponed this Spring. Launch is scheduled for a window between 8:30 AM and 12:30 PM Phoenix time (15:30-19:30 UTV). Coverage and commentary will be broadcast online beginning 90 minutes before launch at

The launch vehicle is an Orbital Sciences Pegasus XL rocket. The Pegasus will be launched from a Lockheed L-1011, named “Stargazer” (below), flying at 40,000 feet. The aircraft has already moved from Vandenberg Air Force base to the Reagan Test Site on the Kwajalein Atoll in the Marshall Islands. The “Stargazer”, Pegasus and NuSTAR will take off and fly to 40,000 feet. Five seconds after drop the Pegasus will ignite and put NuSTAR into a low Earth orbit

The short summary:

  • First observatory to focus high energy X-rays
  • 10 times the resolution and 100 times the sensitivity of previous spacecraft
  • Coordinate observations with Chandra X-ray Observatory
  • Use new mirror and detector technology that was developed in NASA’s basic research program
  • Study large and small black holes, near and far
  • Focus high energy X-rays images (see below)
  • Use nested shell mirrors with 133 in each of two optic units
  • Use state of the art detectors and a 10-meter mast that connects the detectors to the nested mirrors
