And then some questions about the planet were finally answered. The Mariner 4 spacecraft performed the first flyby of Mars in July of '65, and then link in '76 Viking 1 and Viking 2 actually touched down on the Red Planet, offering data on soil samples, link the atmosphere, and even sent back images of the Martian surface. And of course Opportunity, the rover that landed on Mars in 2004, sent its last images back to Earth last link year. Oppy, may you rest in peace.
