What is Common in Divers and Astronauts Training?

Divers and astronauts may seem like they belong to completely different professions, but both require extensive training to perform their duties effectively and safely. Despite the stark differences in their work environments, there are surprising similarities in the training that divers and astronauts undergo. In this article, we will explore some of the commonalities in divers and astronaut training.

Physical Fitness

Both divers and astronauts must maintain a high level of physical fitness. Diving requires a significant amount of physical exertion, especially when performing deep dives or working in challenging environments like currents or low visibility. Similarly, astronauts must be physically fit to handle the physical stress of space travel and perform their duties in microgravity conditions. Both divers and astronauts must also maintain good cardiovascular health and lung capacity.

Underwater Training

Divers must undergo extensive training in underwater skills, including buoyancy control, diving techniques, and the use of specialized equipment like dive computers and rebreathers. Astronauts, on the other hand, must also undergo underwater training to simulate the weightlessness of space. The Neutral Buoyancy Laboratory (NBL) at NASA’s Johnson Space Center is a massive pool that contains a life-size replica of the International Space Station (ISS) where astronauts practice spacewalks and other tasks.

Emergency Procedures

Both divers and astronauts must be prepared to handle emergencies that could arise during their work. Divers must be trained in emergency procedures such as airway management, dive buddy rescue, and decompression illness treatment. Astronauts must also be trained in emergency procedures such as fire response, depressurization, and contingency spacewalks. In both cases, quick thinking, and calm execution of emergency procedures can mean the difference between life and death.

Divers and astronauts must be able to work effectively as part of a team. Diving is often done in pairs or groups, and divers must communicate effectively and coordinate their actions to ensure their safety and accomplish their goals. Similarly, astronauts must work closely with their fellow crew members to complete their missions, whether that means repairing equipment, conducting experiments, or performing spacewalks. Both divers and astronauts must also be able to work with a diverse range of people, including individuals from different cultures and backgrounds.


Finally, both divers and astronauts must be able to adapt to new and challenging situations. Diving conditions can change rapidly, and divers must be prepared to adjust their plans and techniques accordingly. Astronauts must also be prepared to handle unexpected situations in space, from equipment malfunctions to medical emergencies. Both divers and astronauts must be able to remain calm under pressure and think creatively to solve problems.
