June 6th 2012 - 01:35 UTC

NuSTAR is safely on the ground at the stopover airport of Hickam Air Force Base in Hawaii. The Tristar L-1011 aircraft landed around 01:30 UTC with the flight scheduled to resume to the launch site tomorrow.

June 5th 2012 - 22:45 UTC

The Tristar L-1011 aircraft called 'Stargazer' took off from Vandenberg Air Force Base today at 20:59 UTC, 12:59 Local time and is headed for Hickam Air Force Base in Hawaii for an overnight stopover. It is due to land at Hickam Air Force Base at 01:25 UTC. Tomorrow it will then take off for the launch site at Kwajalein Atoll in the Marshall Islands.

June 2nd 2012 - 20:30 UTC

NuSTAR inside the fairing of the Pegasus rocket has been attached to the underside of the L-1011 aircraft that will be used to fly the rocket to 39,000 feet ahead of it's ignition.

The Flight Readiness Review gave a 'GO' yesterday for launch on June 13th at 15:30 UTC.

June 1st 2012 - 23:00 UTC

The NuSTAR (Nuclear Spectroscopic Telescope Array) Spacecraft fully enclosed in the Orbital Sciences Pegasus XL rocket is scheduled to be strapped onto the bottom of the L-1011 aircraft tomorrow, June 2nd, if officials give the 'GO' in today's Flight Readiness Review.

If the vehicle is attached to the aircraft on June 2nd it will take off from Vandenberg Air Force Base on June 5th and fly to the island of Kwajalein.

Launch is set for 15:30 UTC on June 13th, Launch being when the rocket is dropped from the aircraft and it's engines then ignite. The aircraft will fly up to 39,000 feet before dropping the spacecraft, it will free fall for about 5 seconds before igniting it's solid propellent first stage which provides 163,000 pounds of thrust for 70 seconds. The second stage will ignite after the first stage has dropped away and will burn for about 90 seconds providing 44,000 pounds of thrust. During the second stage burn the payload fairing will drop away. The third burn will occur after the second stage falls away and will last 68 seconds, this final burn provides 8,000 pounds of thrust.

The NuSTAR spacecraft will separate from the rocket 10 minutes after the initial release from the L-1011 aircraft. The spacecraft weighs 772 pounds and it's purpose is as an x-ray telescope which will study deep into the black holes of our Universe.

April 19th 2012 - 18:00 UTC
