Jet Propulsion Laboratory and NASA have been producers and users of big data for a long time. You could say it’s part of our DNA. Until recently our big data strategy has been focused only on science and engineering, such as how could we predict hurricanes and earthquakes or find the most interesting rocks on Mars. These are complex and difficult problems to solve, and they take time. So this past summer we decided to put our big data to work against some problems that were closer to home. And the whole initiative was even more successful than we had hoped.
