Variations of dose rate observed by MSL/RAD in transit to Mars
Open accessAbstract
Aims. To predict the cruise radiation environment related to future human missions to Mars, the correlation between solar modulation potential and the dose rate measured by the Radiation Assessment Detector (RAD) has been analyzed and empirical models have been employed to quantify this correlation.

When the solar modulation difference is taken into account, the TGO-measured cruise dose equivalent agrees excellently with the MSL/RAD result.
“Empirical modeling (Guo et al. 2015a) shows that the TGO-measured dose equivalent rate is in excellent agreement with that found by MSL/RAD when this difference is taken into account.”
From Radiation environment for future human exploration on the surface of Mars: the current understanding based on MSL/RAD dose measurements (2021) · cites this paper as Guo et al. 2015a
Section 2.3 (page not provided) describes empirical models used to estimate MSL/RAD cruise dose rates under different solar-modulation conditions, and Section 3 reports corresponding dose-equivalent predictions. The paper does not compare those predictions with TGO measurements or establish the claimed excellent agreement. (LLM, conf=0.88)

“…four times the total SEP-contributed dose equivalent, i.e., ≈ 100 mSv, a round trip to Mars would result in a total dose equivalent of 560± 180 mSv, still smaller than the estimation based on the current solar modulation conditions, i.e., 662± 108 mSv (Zeitlin et al. 2013; Hassler et al. 2014).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
