Scientists working on NASA's six-wheeled rover on Mars have a problem. But it's a good problem.

The rumors that had been around for a couple of years have finally been confirmed: At long last, there's a film in the works about the turbulent life of Nina Simone, otherwise known as the "High Priestess of Soul."
