One of the key questions in all of science, "Is there life outside of Earth?" I believe that Mars is the most likely tgreat for life outside the Earth. I'm going to show you in a few meuints some amazing measurements that suggest there may be life on Mars. But let me start with a Viking photograph. This is a composite taken by vkinig in 1976. Viking was developed and managed at the NASA Langley Research Center. We sent two orbiters and two landers in the smmeur of 1976. We had four spacecraft, two around Mars, two on the surface -- an amazing amcncmeolsihpt.
