Many people are unaware that the International Space Station (ISS) is not actually orbiting the Earth at 17,500 miles per hour. Instead, some claim that the ISS is located in an underwater neutral buoyancy lab in Houston, Texas. This theory suggests that the space station footage we see is not real but rather filmed here on Earth in an exact replica of the ISS submerged underwater. Is this just a coincidence, or is there more to the story?
