Tomorrow, a Space-X Dragon cargo ferry, CRS-10, will be launched to the International Space Station packed with supplies, experiments, tools and food for the six astronauts living and working high above Earth. In the unpressurised cargo hold is a new NASA sensor that will monitor our atmosphere with a helping hand from an ESA device, the Hexapod!
