@chriskunadrive: Samples from Mars? Missouri students created a rover that does that! Isaac Lowe and Olivia Dean from Missouri S&T explains how their world-champion Mars rover uses interchangeable attachments to perform different tasks. One of the most impressive features is a soil-sampling system that can drill into the ground, collect samples, and analyze their composition using a spectrometer. Designed and built by college students, this rover demonstrates the kind of engineering that could help shape the future of space exploration.
