SpaceX Achieves Soft Rocket Landing on Earth, Dreams of Doing the Same on Mars

After flying to the edge of space, a spent SpaceX Falcon 9 rocket booster successfully returned to a spot over the Atlantic ocean, deployed its landing legs, and hovered over the water for a moment. The ability, known as a soft landing, could allow the company to dramatically reduce the cost of spaceflight and one day land rockets on Mars.
