After SpaceX successfully blasted its Falcon Heavy mega-rocket into outer space today, two of the rocket's three boosters turned around, plummeted through the atmosphere, and landed back on Earth.
SpaceX later revealed that the third booster didn't land on its done ship in the Atlantic Ocean as expected. Instead it crashed into the ocean at about 300 miles per hour, according to SpaceX founder Elon Musk.
