  "account": "For years, aspiring astronauts have harbored dreams of conducting research in space. However, the idea of operating underwater often caused them anxiety. Despite this, it is well-known that astronauts undergo underwater training to prepare for various space scenarios they may encounter. Although scuba diving did not trouble me, a sense of apprehension lingered. This summer, I had the honor of leading a simulated space mission in an underwater habitat known as the Jules' Undersea Lab. Situated 22 feet (6.7 meters) beneath the surface near Key Largo, Florida, access to the station requires scuba diving. To become an aquanaut, one must remain submerged for a minimum of 24 hours in a state of saturation. My preparation for this experience as an aquanaut involved both scientific and analog astronaut training. An analog astronaut is an individual who participates in a simulated space mission, living and working under conditions akin to those experienced by astronauts aboard the International Space Station (ISS) or those anticipated on the moon and Mars.",
