A stream of charged particles known as the solar wind flows from the Sun toward Earth. Here, it meets the Earth’s magnetic fields, which shield our planet like a giant umbrella. The Space Umbrella project needs your help investigating this dynamic region, where NASA’s Magnetosphere Multiscale (MMS) mission has been collecting data since 2015. The MMS mission investigates how the Sun and Earth’s magnetic fields connect and disconnect, explosively transferring energy from one to the other in a process that is important to the Sun, other planets, and everywhere in the universe.
With the Space Umbrella project, you will help identify when the MMS spacecraft has observed the strongest interactions between the Earth’s magnetosphere and the solar wind. While these interactions can result in beautiful auroras, they also release energy that could disrupt GPS and communications systems and endanger astronauts. Your work will also help scientists better understand solar storms. Understanding these solar storms can contribute to keeping our astronauts and technology safe.
To get started, visit the Space Umbrella project website and complete the tutorial. The tutorial will teach you everything you need to know, including how to tell when the satellite is inside Earth’s magnetic field and when the magnetosphere is interacting with the Sun’s particles. Everyone is welcome to participate — no prior experience needed!

The Earth’s magnetosphere (orange crescent) is created by Earth’s magnetic field. It deflects those particles like an umbrella.
