With a little over two weeks to go until its California launch, the Sentinel-6 Michael Freilich spacecraft is undergoing final preparations. Technicians and engineers have encapsulated the satellite in the payload fairing - the protective nosecone that will ride atop the SpaceX Falcon 9 rocket. The launch is targeted for Nov. 21.

"We're almost there," said project manager Parag Vaze of NASA's Jet Propulsion Laboratory in Southern California. "Soon, we'll be watching the satellite on its journey into Earth orbit 830 miles above our planet." Project manager Pierrik Vuilleumier of ESA (European Space Agency) echoed the sentiment.

About the size of a small pickup truck, Sentinel-6 Michael Freilich will play a central role in efforts to track sea level rise caused by climate change. What's more, the data that it collects on sea level variations near coastlines will provide information to support coastal management and with planning for floods, while its atmospheric measurements will enhance weather and hurricane forecasts.

Sentinel-6 Michael Freilich is one of two identical satellites that are a part of the Sentinel-6/Jason-CS (Continuity of Service) mission, a U.S.-European collaboration. The 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 oceans, and providing crucial information for operational oceanography, marine meteorology, and climate studies. Sentinel-6 Michael Freilich's twin, Sentinel-6B, is scheduled to launch in 2025.

Satellites help to retrace travel routes of Bronze Age herders in China
Washington DC (SPX) Nov 05, 2020
To retrace the ancient migration routes taken by Bronze Age herders in northwestern China, researchers turned to space. Satellite images allowed researchers to map the distribution of archaeological evidence across the 640,000-square-mile autonomous region known as Xinjiang, according to a study published Wednesday in PLOS One. Interviews with modern-day herders also helped researchers contextualize the data and model the ways ancient herders likely navigated the rugged terrain. "This detai ... read more
