Maria Zuber of MIT discusses her experiences working with the Mars Exploration Rover 'Spirit', and the discoveries it made. Taking advantage of Earth's proximity to Mars, astronomers and scientists are launching several missions to Mars to find out more about our red neighbor. On January 4, 2004, a Mars Exploration Rover called 'Spirit' landed inside a Martian crater with the assistance of Maria Zuber. Zuber monitored the radio tracking of the entry, decent and landing out at the Jet Propulsion Lab in California; however, before she went, she shared with us some of the reasons scientists want to study Mars in the first place. What are we looking for? How similar are these two planets? And is there life on Mars?
