Becoming an astronaut is an exceptionally challenging endeavor.
The universe is a fascinating yet mysterious realm, fraught with dangers. Consequently, astronauts must undergo a rigorous selection and training process that is complex enough to leave anyone feeling overwhelmed just hearing about it.
NASA, the world’s leading astronaut training center in the United States, is actively searching for potential candidates for a new generation of young and passionate astronauts ready to participate in missions to the Moon, Mars, and possibly even further planets.
So, what criteria must one meet to be considered a “standard” astronaut? Recently, a video showcasing a test for NASA astronaut candidates surfaced on social media, and it’s clear from just a glance that the requirements are anything but simple, leaving viewers feeling quite “dizzy”.

The video features a test that candidates must complete while simulating a zero-gravity environment on a special rotating circular platform. The model moves in a continuous parabolic trajectory at increasing speeds, creating a zero-gravity effect for approximately 20 seconds.
If you are an ordinary person, experiencing “motion sickness” and vomiting is practically unavoidable. Remarkably, candidates must practice this exercise 40 times a day.
At this point, many might feel alarmed, but each country has specific health requirements for its astronauts, with a common emphasis on excellent physical fitness. A more crucial factor is the ability to withstand the dizziness caused by a zero-gravity environment.

Zero-Gravity Training Methods
Zero-gravity training is extremely significant for astronauts. It not only helps astronauts adapt to the space environment and maintain their physical and mental health but also plays a vital role in enhancing mission effectiveness and task completion. Through the zero-gravity training process, astronauts can better confront challenges and difficulties while sustaining energy and optimal working conditions.
Specialized Equipment Training: Astronauts will utilize specialized equipment to perform various training exercises, such as weightlifting machines and pools that simulate a zero-gravity environment. These devices can mimic the weightlessness of space, assisting astronauts in adaptation and physical conditioning.
Endurance Training: In space, astronauts lose a certain amount of muscle strength, so endurance training is crucial in zero-gravity workouts. Astronauts improve their physical endurance through long-duration exercises like running, cycling, and rowing.
Balance and Coordination Training: In a zero-gravity environment, astronauts need to maintain their balance and body coordination to avoid unstable movements or falls. To achieve this goal, astronauts will perform various balance and coordination exercises, such as yoga poses and walking, to enhance their body control abilities.
Psychological Training: The zero-gravity environment can also impact astronauts’ mental states, so psychological training is also a part of zero-gravity training. Astronauts will be trained to adjust their mindset to enhance their mental well-being and improve their ability to cope with and adapt to stress.
Exercise is the most important part of zero-gravity training.
The preliminary selection criteria are not overly strict. Candidates only need to be taller than 1.47m, have good eyesight, and maintain stable blood pressure. The astronaut profession does not have an age limit, though most individuals pursuing this field range from 25 to 46 years old.
However, currently, the requirements for astronauts also include social skills. They must not only be in good health but also be able to collaborate effectively with others, be confident, and possess strong pressure management skills in multitasking environments.
Before embarking on missions, they will have to practice public speaking, collaborate with experts, and even engage with government officials. This training prepares astronauts to work effectively with a variety of personalities in everyday life.
Under the video, many viewers expressed their astonishment at the nature of NASA astronauts’ work:
– If I sat in that chair, I probably wouldn’t be able to breathe; just looking at it is terrifying.
– I want to log out of Earth!
– Generally, only those who get accustomed to it can handle it; it’s tough for ordinary people!
Being an astronaut may sound like an incredibly exciting job, but in reality, it requires a high level of knowledge, skills, and physical fitness to fulfill the mission. Only then can we explore the cosmic mysteries that humanity has always sought to uncover.
