Space Perspective plans to take tourists to the stratosphere

Space Perspective wants to make space tourism happen. The company plans to transport up to 8 tourists in a high-altitude, hydrogen-filled balloon to the stratosphere to get a view from an altitude of 100,000 feet. The ballon, called "Spaceship Neptune", has a pressurized cabin and will include both a bar and a restroom.

Test flights with research equipment will start in 2021 and, if all goes well, tourists can board the Neptune in three and a half years.
