Above and Beyond: NASA’s Magnetospheric Multiscale Mission Surpasses Expectations Flying to New Heights in 201712 Jan 2018, 16:38 UTC
In the cold vacuum of space, four satellites travel through the darkness, cruising around Earth at speeds up to 22,300 miles per hour. These spacecraft comprise NASA’s Magnetospheric Multiscale mission, called MMS for short. Looking at electric and magnetic fields, hot plasmas, and high-energy particles, they have been charting the dynamic space environment around Earth for over two years. What they’ve discovered in 2017 is changing how we understand the magnetic environment protecting our planet.
