The Sun throws off an extremely fast stream of charged particles called the solar wind. This solar wind collides with the Earth and its protective magnetic field, generating a shock wave called “the bow shock.” There, at the bow shock, the ever-changing magnetic fields can either make the solar wind messy and dynamic or leave it smooth and stable. That’s where the scientists behind Shock Detectives need your help. Join the Shock Detectives project and help interpret data collected by the Magnetospheric Multiscale (MMS) Mission, whose four spacecraft fly in formation through the bow shock zone. You can help classify patterns in the bow shock and help scientists figure out what governs its behavior.

What you’ll do:
Look at plots of data and learn to recognize regions of “peaceful” and “chaotic” plasma activity.
Click buttons to inform the researchers which time periods are chaotic or peaceful.
When and if you like, you can discuss what you have found with other volunteers and scientists in the Talk forum.
Requirements
Time: 10-15 minutes to complete each tutorial (the project has two related workflows).
Equipment: internet connected computer, tablet, or smartphone
Knowledge: None. An in-project tutorial is provided.
Get started!
Visit the project website on your computer or smartphone.
Choose a workflow, and complete its in-project tutorial to learn how to interpret data from NASA’s Magnetospheric Multiscale (MMS) mission.
Start classifying readings collected by the MMS as indicating “chaotic” or “peaceful” plasma behavior using the Field Guide reference as necessary.
