The next logical step in humans’ exploration of space is to start having more civilian ventures—and commercial, money-making ones—in outer space. NASA is onboard with this step. It has made it a priority to seed and encourage a strong, bustling, and competitive low Earth orbit (LEO) economy with itself as a strong player and user of commercial services and equipment. To NASA, LEO ends at about 1,200 miles above Earth, but that’s where the International Space Station (ISS) orbits and it is relatively easy to get up into LEO and back.
