Exploration of Mars with the Curiosity rover
NASA’s Mars Science Laboratory mission, featuring the Curiosity rover, has been exploring a part of Gale Crater on Mars for the past six years.  This amazing mobile laboratory, with innovative chemical instruments like the Canadian alpha particle X-ray spectrometer (APXS) and the laser-firing ChemCam instrument suite, has been characterising the rocks, soils and atmosphere to try to piece together the past geologic and climate history of Early Mars.  Curiosity’s primary objective if to search for, and characterise, habitable environments – places where the conditions necessary for life could have existed sometime in the distant past, or even today.  Curiosity has already found evidence for extensive ancient lakes that could have supported life as we know it, diverse and complex organic molecules in ancient rocks, and seasonal cycles of atmospheric gases even today.  The Mars 2020 rover, NASA’s next rover, will go a step further and seek out biosignatures – or indicators of possible life in ancient rocks.  It will even collect samples that will be brought back to Earth at a later date for more detailed study and to possibly answer the question “Are we alone?”.  This presentation will summarise how we explore Mars with a rover, some of the key findings from Curiosity and may use lessons learned to better prepare for future robotic and human missions to Mars.

Influence of Lunar Rover on Lunar Surface Temperature
The lunar regolith is a very poor thermal conductor. As a result, the temperature of the surface can fluctuate quickly as the environment changes.  For terrestrial applications it is common to assume that the planet’s surface is fixed at an appropriate temperature. The properties of the lunar regolith indicate that this approach may not be valid for a lunar rover which will experience a varying radiative environment resulting from the presence of the rover itself.
This paper demonstrates the implementation of a published lunar regolith model in NX SST and investigates the influence of a simplified lunar rover on the surface temperature and the impact of these changes on rover thermal performance.
