NASA and Northrop Grumman coordinated with the U.S. Air Force Eastern Range for an earlier launch date for the agency's Ionospheric Connection Explorer, or ICON, spacecraft from Cape Canaveral Air Force Station in Florida. ICON is now targeted for launch on Oct. 9, 2019, aboard a Northrop Grumman Pegasus XL rocket carried by the company's L-1011 Stargazer aircraft.

Stargazer, the last flying Lockheed L-1011 TriStar, took off from Mojave Air and Spaceport this morning. It's headed to Vandenberg AFB to pick up a Pegasus XL rocket and @NASA's ICON satellite ahead of their launch out of Cape Canaveral on October 10.

A Northrop Grumman Pegasus XL rocket is back at Cape Canaveral after a cross-country ferry flight Tuesday under an L-1011 carrier jet, ready for final checkouts and a countdown dress rehearsal before an airborne launch off Florida's east coast Oct. 9 with NASA's Ionospheric Connection Explorer satellite.

The L-1011 carries jet, named "Stargazer," touched down at the Skid Strip runway at Cape Canaveral Air Force Station shortly before 5:30 p.m. EDT (2130 GMT) Tuesday after a nearly six-hour flight fr om Vandenberg Air Force Base, California, where teams readied the Pegasus rocket for flight.

Technicians mated the 634-pound (288-kilogram) ICON spacecraft to the Pegasus XL rocket Sept. 10, then encapsulated the satellite inside the launcher's payload shroud in a clean room at Vandenberg. Then ground teams transferred the 57-foot-long (17-meter) Pegasus XL rocket to the Vandenberg airfield for attachment underneath the L-1011 carrier plane.

The arrival of the Pegasus rocket at Cape Canaveral begins a week of final inspections, testing and a launch day dress rehearsal.

The L-1011 will take off again from the Skid Strip around 8:30 p.m. EDT on Oct. 9 (0030 GMT on Oct. 10) for an hour-long flight to a predetermined drop box around 100 miles (160 kilometers) east of Daytona Beach.

The flight crew aboard the L-1011 will put the airplane on an easterly heading before commanding the release of the winged Pegasus XL at an altitude of around 39,000 feet (11,900 meters).

The drop time is set for 9:30 p.m. EDT on Oct. 9 (0130 GMT on Oct. 10). There's a 90-minute launch window available.

Three solid-fueled rocket motors on the Pegasus XL launcher will propel the ICON spacecraft into a 357-mile-high (575-kilometer) orbit.

ICON carries scientific instruments to investigate plasma waves in the ionosphere, a layer in the upper atmosphere wh ere colorful auroras are generated. Changes in the ionosphere can also affect communications and navigation signals coming from satellites, and ICON will study how weather systems lower in the atmosphere can influence conditions at the edge of space.

Like its Pegasus launcher, the ICON spacecraft was built by Northrop Grumman.

ICON's ride into space has been delayed more than two years by concerns related to its Pegasus rocket.

The mission was originally supposed to launch over the Pacific Ocean near Kwajalein Atoll, the home of a remote U.S. military test site in the Marshall Islands.

Engineers wanted more time to inspect the Pegasus rocket motors after they were mishandled during shipment to Vandenberg. That pushed the launch back from June to December 2017, the next availability in the military-run range at Kwajalein.

Then managers decided to ground the mission to assess the reliability of bolt-cutters used to jettison the Pegasus rocket's payload fairing and separate the satellite in orbit.

NASA and Northrop Grumman tried to launch the $252 million ICON mission twice last year. Both were thwarted by issues related to the solid-fueled rocket's rudder, which used for aerodynamic stability during the launcher's first stage burn.

Managers decided to base the launch out of Cape Canaveral, rather than Kwajalein, last summer.

Workers disconnected the ICON spacecraft from the Pegasus rocket late last year and put it in storage while engineers investigated the recurring issues with the launch vehicle.

The satellite was bolted to the rocket again last month as teams readied for a third launch campaign.

А тем временем Ангара побила державшийся почти полвека рекорд Сатурна-1В - 4.5 года между запусками. 
 За Пегасом почётное третье место.

NASA's Ionospheric Connection Explorer (ICON) is scheduled to be air-launched over the Atlantic Ocean at 9:30 p.m. EDT Wednesday, Oct. 9, by Northrop Grumman's Pegasus XL rocket. Coverage of the prelaunch briefing and launch will air live on NASA Television and the agency's website.

ICON and Pegasus will take off aboard the company's L-1011 Stargazer aircraft fr om Cape Canaveral Air Force Station in Florida for a 90-minute launch window opening at 9:25 p.m.

NASA TV coverage is as follows:

Tuesday, Oct. 8
    [/li]
  • 1 p.m. – Mission briefing from NASA's Kennedy Space Center in Florida. Participants will include:
    • Nicola Fox, Heliophysics division director in NASA's Science Mission Directorate
    • Thomas Immel, ICON principal investigator at the Space Sciences Laboratory at the University of California Berkeley
    • Omar Baez, launch director in NASA's Launch Services Program
    • Phil Joyce, vice president of space launch programs at Northrop Grumman Innovation Systems
    • Steve Krein, vice president of civil and commercial satellites at Northrop Grumman Innovation Systems
    • Representative from the U.S. Air Force 45th Space Wing
    [/li][/LIST]
    Wednesday, Oct. 9
      [/li]
    • 9:15 p.m. – Launch coverage begins
    The deadline for media to apply for accreditation for this launch has passed, but more information about media accreditation is available by emailing ksc-media-accreditat@mail.nasa.gov.

    ICON will study the frontier of space – the dynamic zone high in our atmosphere wh ere terrestrial weather from below meets space weather above. The ionosphere can be a source of great beauty, but also can be disruptive to radio communications and satellites, and astronaut health. ICON will help determine the physical processes at play in the ionosphere and pave the way for mitigating its effects on our technology, communications systems and society.

    ЦитироватьThe launch has been rescheduled to Oct. 10, 2019, following the completion of a joint NASA/Northrop Grumman investigation into a Pegasus sensor reading that was not within normal limits during previous ferry and launch attempt flights. The cause of the issue is understood, and the flight hardware has been modified to address the issue. Two L-1011 flights with Pegasus were conducted to verify the effectiveness of the modification with no issues. Functional tests are being performed on NASA's ICON spacecraft, which utilizes Northrop Grumman's LEOStar-2 platform, to ensure that the ICON spacecraft is ready for the upcoming integration activity, ferry flight and launch.
