MAPPING MARS CRATER LANDING SITES & MODELLING CRATER DYNAMICS COMPUTERS IN GEOLOGY TERM PROJECT STEPHANIE SHAHRZAD NOVEMBER 7, 2015

OUTLINE Introduction Mapping Matlab Conclusion Further research

INTRODUCTION My project in two parts Map 2 proposed 2020 Mars Rover landing sites. Calculate different crater mechanics and distributions. Jezero and Gusev Different in size, same components Spirit Important for the scientific community to understand the different parameters included in deciding the landing site for a rover mission. Important to understand crater dynamics, and their effect on the surface of a planet Data from JMARS and Malin Space Science Systems

MAPPING LANDING SITE 1 – GUSEV CRATER 166 km in diameter Delta -> long period of water flow Spirit is stuck! Technology evaluation

MAPPING LANDING SITE 2 – JEZERO CRATER 45 kilometers in diameter Palaeo lake with drainage Clay minerals Mineralogy, geochemistry, astrobiology

COMPARISON Both show water, but Gusev also have Spirit! Mapping: Inertia Landing ellipses GUSEV JEZERO

MATLAB – CRATER PARAMETERS AND CORRELATIONS Diameter vs. density of bolide Diameter vs. denstity impacted object

Diameter vs. gravitational acceleration

MATLAB – CRATER DISTRIBUTIONS Latitude/longitude distribution Size vs. frequency distribution

SUMMARY & CONCLUSION Landing site Gusev! Craters Direct correlation between a craters size and the different parameters of the surface and impacting object. Southpole trend in latitude/longitude distribution a larger number of smaller craters than larger ones, >300 km in diameter.

FURTHER RESEARCH Which crater was the best choice? Rover! Mineralogy Crater size analysis -> using actual data The crater distribution -> benefit from using > ~ 90 craters I used.
