NASA's PACE Mission Aims to Vastly Increase Understanding of the Oceans, Atmosphere

Spaceflight Now - From the oceans to the atmosphere, there’s still quite a bit we don’t understand about our planet. NASA’s latest Earth-observing spacecraft hopes to greatly expand our knowledge of the globe in just a few years.
The PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) spacecraft is the next payload to launch into orbit that will build upon more than 20 years of direct Earth observation. Dr. Nicola Fox, the associate administrator for   NASA’s Science Mission Directorate, described the spacecraft as a “jewel” among the Earth-observing fleet.
