MSL’s RAD Measures Radiation from Solar Storm


The largest solar particle event since 2005 hit the Earth, Mars and the Mars Science Laboratory spacecraft travelling in-between, allowing the onboard Radiation Assessment Detector to measure the radiation a human astronaut could be exposed to en route to the Red Planet.

On Sunday, a huge coronal mass ejection erupted from the surface of the sun, spewing a cloud of charged particles in our direction, causing a strong “S3” solar storm. A NASA Goddard Space Weather Lab animation of the CME illustrates how the disturbance impacts Earth, Mars and several spacecraft. Solar storms can affect the Earth’s aurorae, satellites, air travel and GPS systems; no harmful effects to the Mars Science Laboratory have been detected from this solar event.
