A new all-weather radar imaging satellite for China’s civilian-oriented fleet of Gaofen Earth observatories launched Wednesday aboard a Long March 4C rocket, according to Chinese state media.

SpaceX launched twin satellites for NASA Wednesday that will study how the electrically-charged solar wind interacts with Earth’s magnetic field, creating constantly changing and occasionally dangerous “space weather” affecting satellites, electrical grids and other critical systems.

SpaceX scrubbed an attempt to launch a commercial Falcon 9 rocket Sunday less than a minute before liftoff, blaming a sensor issue on the vehicle’s first stage and pushing back the company’s first national security mission for the U.S. government at least 24 hours.
