Abstract

On November 2014, the Philae lander impacted the surface of comet 67P/Churyumov-Gerasimenko as a part of the ESA’s Rosetta mission. The purpose of the mission was to gather data about the comet's surface and composition. Although the lander ended up bouncing off the surface of the comet, eventually landing on its side in another area of the comet - thus not being able to fulfill the purpose of the mission - the ESA was able to retrieve accelerometer readings from their instrument, the SESAME-CASSE accelerometer. However, since the lander was unable to gather much more information about the layers of the surface, it is interesting that scientists were able to gather such conclusions about the comet’s layers. Over the process of my research, I aimed to recreate the landing of Philae to determine whether it is possible to conclude that the comet has layers from accelerometer data. Furthermore, through different types of drops, we were able to learn more about how different surface materials can affect the way the accelerometer records data and the way the foot of the model interacts with the different surfaces and layers.

Summary of research results to be presented

Over the course of my research, we discovered a trend in our data that we believe is an indication of the layers of a surface. We concluded that due to the differences in the behavior of surface materials, they interact differently with an accelerometer, which allows us to conclude that it is possible to conclude the presence of layers on a comet.
