Few non-astronauts have ever visited the International Space Station, which orbits the Earth and is used to conduct scientific experiments. But this summer, NASA announced that the facility will become a space hotel of sorts, allowing two private citizens per year to stay at the station for up to 30 days each. Tickets won’t be cheap; it’ll cost $35,000 per night to sleep in the station and use its amenities, such as water, air, and internet. Visitors will also pay a much higher sum for a private spaceflight company to get them to and from the space station. In the past, NASA has been reluctant to use the station for commercial business, but Bill Gerstenmaier, head of human exploration, predicts this is the start of a new era. “We have no idea,” he says, “what kinds of creativity and literally out-of-the-world ideas can come from private industry.”
