Français : Schéma comparant les doses de rayonnement recu dans le cadre d'une mission habitée martienne (séjour de 500 jours, transit de 180 jours) avec les doses recues sur Terre ou en orbite basse. Pour Mars les données sont issues des mesures effectuées par MSL/Curiosty. Les données sont fournies en équivalent millisievert, c'est à dire sont pondérées en fonction de la nature du rayonnement. Schéma avec libellé en francais. English: PIA17601: Radiation Exposure Comparisons with Mars Trip Calculation
12.09.2013 http://mars.jpl.nasa.gov/msl/multimedia/images/?ImageID=5771 Measurements with the MSL Radiation Assessment Detector (RAD) on NASA's Curiosity Mars rover during the flight to Mars and now on the surface of Mars enable an estimate of the radiation astronauts would be exposed to on an expedition to Mars. NASA reference missions reckon with durations of 180 days for the trip to Mars, a 500-day stay on Mars, and another 180-day trip back to Earth. RAD measurements inside shielding provided by the spacecraft show that such a mission would result in a radiation exposure of about 1 sievert, with roughly equal contributions from the three stages of the expedition. A Sievert is a measurement unit of radiation exposure to biological tissue. This graphic shows the estimated amounts for humans on a Mars mission and amounts for some other activities. NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the Mars Science Laboratory Project and the mission's Curiosity rover for NASA's Science Mission Directorate in Washington. The rover was designed and assembled at JPL, a division of the California Institute of Technology in Pasadena.
