On June 3 at 16:17 UTC, a Long March-3B launched the Fengyun-4B weather satellite into a geostationary transfer orbit. Most of the satellite’s 5,300-kilogram launch mass was propellant, which will be used to raise it into geostationary orbit.

Fengyun-4B carries a suite of instruments for Earth observation, including the first high-resolution sounder to be put into geostationary orbit, as well as several imagers and a Space Environment Monitoring Package that contains a host of sensors designed to detect high energy particles, magnetic field changes, radiation, and surface charge.
