This is an artist's concept of NASA's Mars Science Laboratory spacecraft during its cruise phase between launch and final approach to Mars. The spacecraft includes a disc-shaped cruise stage (on the left) attached to the aeroshell. The spacecraft's rover (Curiosity) and descent stage are tucked inside the aeroshell.

The largest solar particle event since 2005 has been detected by the radiation-
monitoring instrument aboard the Mars Science Laboratory spacecraft, on its way from
Earth to Mars.
The Radiation Assessment Detector, inside the mission's Curiosity rover tucked inside
the spacecraft, is measuring the radiation exposure that could affect a human astronaut
on a potential Mars mission. It has measured an increase resulting from a Jan. 22 solar
storm observed by other NASA spacecraft. No harmful effects to the Mars Science
Laboratory have been detected from this solar event.
