In the meantime, you can sort of get a sense of what it feels like to stand on the Red Planet thanks to a new 360-degree video from NASA's Mars Curiosity rover. The video, created by stitching together 57 separate still images captured by the Mars Hand Lens Imager (MAHLI) on the end of the rover's robotic arm, was posted to Curiosity's Facebook page over the weekend. It was quickly re-shared by Facebook head honcho Mark Zuckerberg, who has been bullish on Facebook's new built-in 360-degree video playing capabilities introduced late last year. As Zuck wrote of the Curiosity 360 video: "This is just the beginning of what we can do with virtual reality and 360 video. Pretty amazing."
