Stargazer Aircraft Airborne with Pegasus XL, ICON Satellite

Bob Granath Posted on November 7, 2018

The Northrop Grumman L-1011 Stargazer aircraft carrying a Pegasus XL Rocket with NASA’s Ionospheric Connection Explorer, or ICON, satellite is airborne after taking off from the Skid Strip runway at Cape Canaveral Air Force Station in Florida.

Northrop Grumman produces the Pegasus XL, a small expendable rocket that attaches beneath the Stargazer aircraft and is carried to 39,000 feet to be released for launch. It is the only airborne-launched rocket.

The Pegasus XL can carry a payload up to 992 pounds to low-Earth orbit. The rocket weighs about 51,000 pounds and measures 55.4 feet in length and 50 inches in diameter. Pegasus has a wing span of 22 feet

With the Stargazer aircraft flying over the Atlantic Ocean about 50 miles offshore from Daytona Beach Florida, the Pegasus rocket will be released. Five seconds later, the solid propellant engine will ignite and boost the ICON satellite to orbit.

Did you know!

The L-1011 Stargazer is a mobile launch platform and the only one of its kind in the world.

The 90-minute launch window opens at 3 a.m. EST, with a targeted release at 3:05 a.m. EST about 50 miles east of Daytona Beach, Florida. Ignition of the Pegasus XL rocket occurs five seconds after release from the Stargazer.

ICON Launch Update

Bob Granath Posted on November 7, 2018

NASA and Northrop Grumman have postponed today’s launch attempt of NASA’s Ionospheric Connection Explorer, or ICON, mission due to off-nominal data observed on the Pegasus XL rocket, during the captive carry flight. The L-1011 Stargazer carrier aircraft returned to Cape Canaveral Air Force Station in Florida and the team will begin an investigation into the issue. The ICON spacecraft remains healthy. The team is evaluating the next launch attempt.

ICON Launch Update

Bob Granath Posted on November 8, 2018

NASA and Northrop Grumman have postponed the Nov. 7 launch attempt of NASA’s Ionospheric Connection Explorer, or ICON, mission due to off-nominal data observed on the Pegasus XL rocket, during the captive carry flight. The L-1011 Stargazer carrier aircraft returned to Cape Canaveral Air Force Station in Florida and the team will begin an investigation into the issue. The ICON spacecraft remains healthy. The team is evaluating the next launch attempt.

Are there any restrictions on a launch window like there were when it was originally supposed to be flown out of Kwajalein? Or now that it's at the Cape whenever things are ready to go they'll set a new date X days away and go?

And would the Range have any problems with for example launching a Falcon 9 in the afternoon and then the Pegasus the same night? Then again there isn't a whole lot scheduled at the Cape for the rest of the year, so even if you'd want a gap it wouldn't be all too hard.

Cross-post; ER is not as open as may initially appear:

NASA and Northrop Grumman are not expected to attempt a launch of the Pegasus rocket Thursday, as officials continue evaluating pesky problems plaguing the launcher after an aborted try to send NASA's ICON ionospheric probe into orbit early this morning.

A new launch date has not been determined, but the availability of the Air Force's Eastern Range to support the mission is in question the next few days.

A SpaceX Falcon 9 rocket is set for a static fire attempt at the Kennedy Space Center as soon as Sunday, followed by a launch no earlier than Nov. 15 carrying a commercial communications satellite.

That mission, coupled with other maintenance activity on the range, could be problematic for NASA and Northrop Grumman managers to find an opening for a launch attempt in the coming days, assuming the Pegasus is cleared for flight.

ICON Launch Update

Bob Granath Posted on November 9, 2018

NASA and Northrop Grumman are continuing to investigate the off-nominal data observed during the Pegasus XL rocket’s Nov. 7 launch attempt for the agency’s Ionospheric Connection Explorer, or ICON, mission. The next launch attempt will be evaluated once the investigation is complete. The ICON spacecraft remains healthy.

ICON cannot reach its target orbit from the west coast.
