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.

NASA to Hold Launch Readiness Review for ICON

ICON spacecraft artist renderingNASA 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.

NASA’s ICON launch now targeted for Oct. 6

ICON spacecraft artist renderingNASA and Northrop Grumman are now targeting Saturday, Oct. 6, 2018, for the launch of the agency’s Ionospheric Connection Explorer, or ICON. The spacecraft will launch aboard a Northrop Grumman Pegasus XL rocket from Cape Canaveral Air Force Station in Florida. The launch window is 90 minutes starting at 4:00 a.m. EDT and ICON will be launching off the coast of Daytona at 39,000 ft. at a heading of 105.0 degrees. The June launch was postponed after off-nominal data was detected during the ferry flight of Pegasus. The root cause was traced to a faulty sensor, which has been replaced.

ICON Mission Update

NASA is postponing launch of the Ionospheric Connection Explorer (ICON) until 2018. The mission was previously planned to launch Dec. 8, 2017, on an Orbital ATK Pegasus XL rocket from the Reagan Test Site on Kwajalein Atoll in the Marshall Islands. NASA and Orbital ATK need additional time to assess a separation component of the rocket. More information on a revised launch date will be provided once it becomes available.
