Going to Mars The Mars Science Laboratory spacecraft containing the Curiosity rover, was launched from Earth in November 2011 and arrived at Gale crater on Mars in August 2012. Zeitlin et al. (p. 1080) report measurements of the energetic particle radiation environment inside the spacecraft during its cruise to Mars, confirming the hazard likely to be posed by this radiation to astronauts on a future potential trip to Mars. Williams et al. (p. 1068, see the Perspective by Jerolmack) report the… Expand
Charged particle spectra measured during the transit to Mars with the Mars Science Laboratory Radiation Assessment Detector (MSL/RAD).
TLDR
The first measurements of charged particle fluxes inside a spacecraft during the transit from Earth to Mars are presented. Expand
Measurements of the neutron spectrum in transit to Mars on the Mars Science Laboratory.
TLDR
This work applies an inversion method (based on a maximum-likelihood estimation) to calculate the neutron and gamma spectra from the RAD neutral particle measurements, and finds that the total neutron-induced dose rate is 6±2 μGy/day and the dose equivalent rate is 30±10 μSv/day. Expand

Mars’ Surface Radiation Environment Measured with the Mars Science Laboratory’s Curiosity Rover
TLDR
Measurements of the absorbed dose and dose equivalent from galactic cosmic rays and solar energetic particles on the martian surface for ~300 days of observations during the current solar maximum provide insight into the radiation hazards associated with a human mission to the surface of Mars and provide an anchor point with which to model the subsurface radiation environment.

Observations of neutron radiation environment during Odyssey cruise to Mars.
TLDR
It is found that the Odyssey ambient neutron environment during May - September 2001 yields 10.6 ± 2.0 μSv per day, which is in good agreement with results reported for a similar measurement made with an instrument aboard the Mars Science Laboratory during its cruise to Mars in 2011-2012. Expand

The radiation environment on the surface of Mars - Summary of model calculations and comparison to RAD data.
TLDR
Experimental results from the Radiation Assessment Detector of the Mars Science Laboratory are compared to model results from GEANT4, HETC-HEDS, HZETRN, MCNP6, and PHITS and Charged and neutral particle spectra and dose rates measured between 15 November 2015 and 15 January 2016 and model results calculated for this time period are investigated.
