Slipped about a week. Was mentioned in L2 yesterday, but without a new date. Florida Today saying might not be before October 31.

NASA’s ICON Launch Delayed; New Launch Date to Come

Bob Granath Posted on October 23, 2018

NASA and Northrop Grumman have delayed the launch of the agency’s Ionospheric Connection Explorer, or ICON, to conduct further pre-launch testing on the rocket. Upon completion of the testing, a new launch date will be established.

The spacecraft is launching aboard a Northrop Grumman Pegasus XL rocket from Cape Canaveral Air Force Station (CCAFS) in Florida. The L-1011 Stargazer carrying the Pegasus rocket arrived at CCAFS last Friday and will remain in Florida to conduct the testing. The spacecraft remains in good health.

The pre-launch mission briefing originally scheduled for Wednesday, Oct. 24, also has been postponed and will be rescheduled at a later date.

ICON Prelaunch Flight Test Set for Oct. 27

Al Feinberg Posted on October 26, 2018

NASA and Northrop Grumman will be conducting a flight of the L-1011 carrying Pegasus on Saturday, Oct. 27 to perform further prelaunch testing. Once the flight is completed, the team will review the test data and ensure readiness to proceed with remaining preparations for launch. This includes working with the Eastern Range to determine the new launch date. Currently, there is Range availability from Oct. 31 through Nov. 8.

NASA, Northrop Grumman Reviewing Flight Test Data

Bob Granath Posted on October 30, 2018

NASA and Northrop Grumman completed a test flight of the L-1011 Stargazer aircraft from Cape Canaveral Air Force Station in Florida on Sunday, Oct. 28. Carrying Pegasus XL and NASA’s Ionospheric Connection Explorer (ICON), the 4-hour, 45-minute flight tested the aircraft’s systems prior to launch.

A new launch date for the ICON mission will be determined after the team finishes processing and reviewing the data.

NASA to Hold Launch Readiness Review for ICON

Anna Heiney Posted on November 1, 2018

NASA and Northrop Grumman will hold a Launch Readiness Review early next week at NASA’s Kennedy Space Center in Florida to ensure preparations are continuing on track for the launch of the agency’s Ionospheric Connection Explorer, or ICON, satellite.

ICON will be launched by Northrop Grumman’s Pegasus XL rocket which will be carried aloft by the L-1011 Stargazer aircraft taking off from the Skid Strip at Cape Canaveral Air Force Station in Florida.

The ICON satellite mission is expected to launch no earlier than Wednesday, Nov. 7 with a 90-minute launch window opening at 3 a.m. EST. Release from the Stargazer is anticipated for 3:05 a.m. ICON is designed to study the dynamic zone high in the atmosphere where terrestrial weather from below meets space weather from above.

Follow the prelaunch coverage and the launch on NASA Television at:
https://www.nasa.gov/live

Tuesday, Nov. 6
3 p.m. – NASA EDGE webcast from Cape Canaveral Air Force Station will discuss ICON spacecraft operations, science and engineering, as well as launch processing of the Northrop Grumman L-1011 Stargazer with the Pegasus rocket.

Wednesday, Nov. 7
2:45 a.m. – Launch coverage begins at 2:45 a.m.

Launch Week Begins for ICON

Anna Heiney Posted on November 5, 2018

NASA and Northrop Grumman will hold a Launch Readiness Review at the agency’s Kennedy Space Center in Florida at 9 a.m. EST Tuesday, Nov. 6, to ensure preparations are on track for launch of NASA’s Ionospheric Connection Explorer (ICON) satellite.

ICON is scheduled to launch Wednesday, Nov. 7, by Northrop Grumman’s Pegasus XL rocket, which will be carried aloft by the company’s L-1011 Stargazer aircraft taking off from the Skid Strip at Cape Canaveral Air Force Station in Florida. The 90-minute launch window opens at 3 a.m., with a targeted release at 3:05 a.m. Ignition of the Pegasus XL rocket occurs five seconds after release from the Stargazer.

ICON is designed to study the dynamic zone high in the atmosphere where terrestrial weather from below meets space weather from above.

Launch Readiness Review Completed for ICON

Bob Granath Posted on November 6, 2018

NASA and Northrop Grumman completed their Launch Readiness Review on Tuesday, Nov. 6, at the agency’s Kennedy Space Center in Florida. There are no technical issues being worked at this time. NASA’s Ionospheric Connection Explorer, or ICON, satellite mission is scheduled to launch Wednesday, Nov. 7, by Northrop Grumman’s Pegasus XL rocket, which will be carried aloft by the company’s L-1011 Stargazer aircraft taking off from the Skid Strip at Cape Canaveral Air Force Station in Florida.

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

The official weather forecast calls for a 90 percent chance for favorable conditions for launch. The primary launch weather concerns are cumulous clouds.

ICON is designed to study the dynamic zone high in the atmosphere where terrestrial weather from below meets space weather from above.

Tour the Plane Giving NASA’s ICON a Ride to Space


NASA Goddard
Published on Nov 6, 2018

Early in the morning of Nov. 7, 2018, NASA launches the Ionospheric Connection Explorer, or ICON, a spacecraft that will explore the dynamic region where Earth meets space. ICON launches on a Northrop Grumman Pegasus XL rocket, which is carried aloft by the Stargazer L-1011 aircraft.

Join NASA on a behind-the-scenes tour of this plane, once a jet airliner and now uniquely retrofitted to boost spacecraft into low-Earth orbit. Learn about ICON’s science and meet the people — including an engineer, technician, and pilot — who will help launch the spacecraft into orbit.

Confirmation of scrub.

SFN reports the delays so far have been due to:

* 2017-2018: Mishandling of rocket motors + cutters for fairing and spacecraft adapter.
* June-October: Rudder fin actuator problems.
* October-November: GPS receiver used during the Pegasus drop gets signal but displays error during ferry flight.

Has any of these glitches reocurred, possibly the one with the GPS receiver?
