If you’re someone who’s traveled in your life, you’ve probably seen all kinds of airplanes, big and small. But, none of them have been as large as this baby. It’s called the Stratolaunch, and it’s designed to launch satellites or other payloads into low-earth orbit. Essentially two planes joined together at the wing, the Stratolaunch uses six Boeing 747 engines, enough to allow a payload capacity of over 500,000 pounds. It can hold enough fuel to offer a range of up to 2,000 nautical miles. That means it can deliver different payloads into multiple orbits during the same flight while saving money over the traditional three-stage launch systems currently used on a regular basis.
