I've just stumbled across this thread at the Unmanned Spaceflight forum, and thought it would be good to share it here, amid the usual threads about
martian "anomalies" and NASA "lies" - MSL Scientific Results
The thread lists some scientific papers based on Curiosity's results. Here are some of the abstracts I found interesting:
Volume mixing and isotope ratios secured with repeated atmospheric measurements taken with the Sample Analysis at Mars instrument suite on the
Curiosity rover are: carbon dioxide (CO2), 0.960(±0.007); argon-40 (40Ar), 0.0193(±0.0001); nitrogen (N2), 0.0189(±0.0003); oxygen, 1.45(±0.09) ×
10−3; carbon monoxide, < 1.0 × 10−3; and 40Ar/36Ar, 1.9(±0.3) × 103. [...] The 40Ar/36Ar ratio is consistent with martian meteoritic values,
which provides additional strong support for a martian origin of these rocks. [...] This heavy isotope enrichment in carbon supports the hypothesis
of substantial atmospheric loss.
Stable isotope ratios of H, C, and O are powerful indicators of a wide variety of planetary geophysical processes, and for Mars they reveal the
record of loss of its atmosphere and subsequent interactions with its surface such as carbonate formation. [...] Comparison between our measurements
in the modern atmosphere and those of martian meteorites such as ALH 84001 implies that the martian reservoirs of CO2 and H2O were largely
established ~4 billion years ago, but that atmospheric loss or surface interaction may be still ongoing.
And the one about the radiation dozes on a round trip to Mars
The Mars Science Laboratory spacecraft, containing the Curiosity rover, was launched to Mars on 26 November 2011, and for most of the 253-day,
560-million-kilometer cruise to Mars, the Radiation Assessment Detector made detailed measurements of the energetic particle radiation environment
inside the spacecraft. These data provide insights into the radiation hazards that would be associated with a human mission to Mars. We report
measurements of the radiation dose, dose equivalent, and linear energy transfer spectra. The dose equivalent for even the shortest round-trip with
current propulsion systems and comparable shielding is found to be 0.66 ± 0.12 sievert.
For the record, 0.67 sievert was the highest dose received by a worker responding to the Fukushima emergency.
