Josef Aschbacher, head of ESA’s Earth observation programs, recently spoke with Spaceflight Now about the importance of the Sentinel 5P satellite mission designed for air quality measurements from space, and discussed increasing data usage from Europe’s Copernicus environmental network, and plans to expand the flagship Earth observation fleet.
Earl Maize, who leads the Cassini mission at NASA’s Jet Propulsion Laboratory, started working on the Saturn orbiter project in 1992. In September, the spacecraft will take an intentional plunge into Saturn’s atmosphere, gaining unprecedented up-close measurements and ending a 13-year odyssey round the ringed planet.
Anton Zeilinger first proposed the idea for a satellite-based quantum communications experiment to the European Space Agency in 2001, but officials did not forward with the idea. A decade-and-a-half later, the world-renowned physicist’s former student leads a Chinese project aimed at proving quantum teleportation and ultra-secure data links at global scale for the first time.
