During the MIT dinner talk, the two NASA professors shared with us their experience in working on the Mission; explaining how the collected samples will be selected and studied with aims of constraining the habitability of Mars, looking for signs of past life, and reconstructing the evolution of Mars' geology and climate. This experience was a great opportunity for Kit Sam students to discover their interests in STEM, and all participants had a really enjoyable time at the talk. A huge thanks to the Hong Kong MIT club for this opportunity, and Professor Bosak and Professor Weiss for their insightful sharing.
