description Overview

Arase

Arase, formerly known as the Exploration of Energization and Radiation in Geospace (ERG), is a Japanese scientific satellite operated by JAXA. Launched in 2016, it was designed to study the Earth's inner magnetosphere, including the Van Allen radiation belts and the processes that accelerate high-energy particles. Its instruments measure charged particles, plasma waves, and electric and magnetic f...

GRACE-FO

GRACE-FO, the Gravity Recovery and Climate Experiment Follow-On, is a joint NASA and German Research Centre for Geosciences Earth-observation mission launched in 2018. Its two satellites measure minute changes in the distance between them as they orbit, allowing scientists to map variations in Earth's gravity field. The data are used to track changes in groundwater, ice sheets, glaciers, sea level...
