IRIS/Pegasus Motor Arrival

Northrop Grumman's L-1011 Stargazer takes off from Vandenberg Air Force Base in California on Oct. 1, 2019. The company's Pegasus XL rocket, containing NASA's Ionospheric Connection Explorer (ICON), is attached beneath the aircraft. The explorer is targeted to launch on Oct. 9, 2019, from Cape Canaveral Air Force Station in Florida. ICON will study the frontier of space - the dynamic zone high in Earth's atmosphere where terrestrial weather from below meets space weather above.

The Sentinel-6 Michael Freilich satellite, secured inside a shipping container, arrives at Vandenberg Air Force Base in California on Sept. 24, 2020, aboard an Antonov cargo aircraft. The mission is an international partnership and the first launch of a constellation of two satellites that will observe changes in Earth’s sea levels for at least the next decade. Launching atop a SpaceX Falcon 9 rocket, Sentinel-6 Michael Freilich is targeted to lift off from Vandenberg’s Space Launch Complex 4 on Nov. 10, 2020. The Launch Services Program at Kennedy is responsible for launch management.

Family members of Dr. Michael Freilich, for whom the Sentinel-6 Michael Freilich satellite is named, gather at Vandenberg Air Force Base in California on Nov. 20, 2020, the day before the spacecraft’s planned launch atop a Falcon 9 rocket. Freilich served as director of NASA’s Earth Science Division in the Science Mission Directorate at the agency’s Headquarters from 2006 until his retirement in 2019. A tireless advocate for advancing satellite measurements of the ocean, he was instrumental in advancing ocean altimetry and helped drive the evolution of NASA Earth science from a program that launched an Earth-observing space mission every few years to one that launches several missions each year. Freilich died Aug. 5, 2020, of pancreatic cancer. Sentinel-6 Michael Freilich launched Nov. 21, 2020, at 9:17 a.m. PST (12:17 p.m. EST). NASA’s Launch Services Program at Kennedy Space Center was responsible for launch management.
