This NASA video showcases Curiosity, NASA’s Mars rover that will, over a 23-month mission, collect and analyze Martian soil and rock samples while traversing a targeted area of the planet testing for evidence of current or past life. Scientists specifically chose Curiosity’s landing site because it contains minerals usually formed in water, and water is a key marker for the potential for living organisms. The video provides a behind-the-scenes view of how NASA engineers designed Curiosity to be sturdy but light and to be highly maneuverable and stable.
