The Sentinel-6 Michael Freilich spacecraft will soon be heading into orbit to monitor the height of the ocean for nearly the entire globe.
VANDENBERG AIR FORCE BASE, Calif. (NASA PR) — Preparations are ramping up for the Nov. 10 launch of the world’s latest sea level satellite. Since arriving in a giant cargo plane at Vandenberg Air Force Base in California last month, Sentinel-6 Michael Freilich has been undergoing final checks, including visual inspections, to make sure it’s fit to head into orbit.
Surviving the bone-rattling vibrations and sounds of launch atop a Falcon 9 rocket is just the start of the mission. Once in orbit some 830 miles (1,336 kilometers) above Earth, Sentinel-6 Michael Freilich has the task of collecting sea level measurements with an accuracy of a few centimeters (for a single measurement) for more than 90% of the world’s oceans. And it will be making those measurements while repeatedly flying through an area of intense radiation known as the South Atlantic Anomaly, which can scramble electronics.
That’s why ...
