Robot Explorers – Near the end of the twentieth century, we began launching unmanned probes into the far reaches of the solar system. What they discovered was amazing and, in some cases, unexpected. Now after dozens of probes have been deployed, the exploration continues. New space missions are underway, and many of these robust spacecrafts are still operational, beaming their knowledge back to Earth every day. We will pay tribute to these robots who have explored in our stead and experience what they have taught us about our solar system. Narrated by Brent Spiner of TV’s Star Trek: Showing in 3D!
