NASA and ESA Spacecraft Track a Solar Storm Through Space (see film) - UNIVERSE


Scientists used data from 10 NASA & ESA spacecraft to track a coronal mass ejection (CME) through the solar system.
On Oct. 14, 2014, a CME left the Sun, as measured by spacecraft that watch for CMEs from afar using an instrument called a coronagraph. From there, the CME washed over spacecraft throughout the inner solar system – including by Curiosity on Mars, near comet 67P/Churyumov-Gerasimenko, and out to Saturn.

This wealth of data is a boon for scientists working on space science simulations. At NASA’s Goddard Space Flight Center in Greenbelt, Maryland, scientists work to validate, host, and improve such simulations, and this new information provides the most comprehensive look to date at how the speed of a CME evolves over time.
