SpaceX’s Crew Dragon – named Freedom by the Crew-4 astronauts – atop the company’s Falcon 9 rocket, rolls out to Launch Complex 39A at NASA’s Kennedy Space Center on April 19, 2022. NASA astronauts Kjell Lindgren, Bob Hines, and Jessica Watkins, and ESA (European Space Agency) astronaut Samantha Cristoforetti, who arrived at Kennedy one day ago, will fly to the International Space Station on NASA’s SpaceX Crew-4 mission. Liftoff is targeted for Saturday, April 23, at 5:26 a.m. EDT.

NASA Launch Commentator Derrol Nail participates in the launch broadcast for the Sentinel-6 Michael Freilich mission on Nov. 21, 2020, at Vandenberg Air Force Base in California. The SpaceX Falcon 9 rocket carrying the Sentinel-6 Michael Freilich spacecraft launched from Vandenberg’s Space Launch Complex 4 at 9:17 a.m. PST (12:17 p.m. EST). The Sentinel-6/Jason-CS (Continuity of Service) mission consists of the Sentinel-6 Michael Freilich satellite, which will be followed by its twin, the Sentinel-6B satellite, in 2025. The Sentinel-6/Jason-CS mission is part of Copernicus, the European Union’s Earth observation program, managed by the European Commission. Continuing the legacy of the Jason series missions, Sentinel-6/Jason-CS will extend the records of sea level into their fourth decade, collecting accurate measurements of sea surface height for more than 90% of the world’s seas, and providing crucial information for operational oceanography, marine meteorology, and climate studies. NASA’s Launch Services Program at Kennedy Space Center was responsible for launch management.
