What is NASA’s Global Precipitation Measurement (GPM) Mission and Why is it Important?

The Global Precipitation Measurement (GPM) mission is an international network of satellites that provide next-generation global observations of rain and snow. Led by NASA and the Japan Aerospace Exploration Agency (JAXA), GPM builds upon the legacy of the Tropical Rainfall Measuring Mission (TRMM) to set a new standard for precipitation measurements from space.

Mapping Earth’s Ever-Changing Magnetic Field: How ESA’s Swarm Mission Helps Improve the World Magnetic Model

The Swarm mission was launched by ESA in 2013 to study and precisely map variations in Earth’s magnetic field over space and time. The constellation consists of three identical satellites carrying sophisticated magnetometers and electric field instruments. Swarm provides multi-point measurements of the magnetic signals from the magnetosphere, ionosphere, lithosphere and the core.
