Project Selection • We looked through the topics and discussed which one we all had an interest in. • When we got down to three we did our research and found which one had the most resources available. • After about a week of research we came to a consensus about our topic.
Topic of Study • Categorize lunar impact craters 30km(±4km) in diameter as either Primary or Secondary based upon crater depth, diameter, and regional surroundings
Background Info • Morphology • Primary vs. Secondary • Crater counting
Primary Data Gathering • Gathered crater information (Identity, Diameter, Longitude & Latitude) • Compiled and documented craters that ranged from 26 – 34 kilometers. • Made use of Google Earth’s Moon feature to collect pictures of all the craters registered.
Detailed Data gathering • Examined Crater Region for similar sized impact sites • Calculated a ratio between given Depth and Diameter • Looked for trends between separate sets of data • Predicted Crater type upon the look of the Impact region against the Depth-Diameter Ratio
Data Crater Name: Lambert Location: 25.80°N 21.00°W Depth/Diameter Ratio: .09 Depth: 2.7km Diameter: 30km Regional Appearance; Crater is surrounded by many miniscule craters, Crater appears to have a complex inner geography Link to full spreadsheet: http://bit.ly/dVJH7j
Conclusion • Currently our team lacks sufficient amounts of data to come to determine any sort of trend between the Depth/Diameter Ratio and the appearance of the crater region to determine the classification of the impact sites.
Future Studies • Continue to gather data concerning crater depth and diameter • Possibly expand set of data to include; Crater age, edge slope, and temperature • Build up a website to exhibit set of craters coupled with their related information
