As featured in Seas Of The Sun: The Story Of The Cluster Mission, and inspired by the European Space Agency's Cluster Mission -- a pioneering heliophysics mission which revolutionised the way we see space plasma: superheated gas produced by stars like our own sun, and perhaps best known for producing the Earth's Aurora Borealis.
These shirts were commissioned by the ESA mission team behind Cluster and feature a front design depicting Earth's magnetosphere interacting with space plasma, and the back features a list of significant Cluster mission dates -- just like a tour shirt, because as we know, space rocks!
