Reusable Rockets

SpaceX, the company that has helped to pioneer the private exploration of space, has released a video of one of their rockets taking off from a launch pad, hovering for a short while and then descending and landing on the same pad that they took off from. To me, this is nothing short of amazing. Watch for the cattle at the bottom of the frame for a little crazy juxtaposition.
Elon Musk the CEO of SpaceX, and Tesla motors, has also grabbed headlines lately by proclaiming that SpaceX will land a human on Mars by 2026.
