How To Become An Astronaut: A Step-By-Step Guide

Becoming an astronaut is a dream that many people have had since childhood. From looking up at the night sky to reading about space exploration in books, it's a fascination that can stay with you for a lifetime. However, the path to becoming an astronaut is not an easy one. It requires a lot of preparation, dedication, and hard work. In this article, we'll provide a step-by-step guide on how to become an astronaut.

Step 1: Get a degree in a relevant field

To become an astronaut, it's essential to have a degree in a relevant field such as engineering, mathematics, or physics. However, NASA also accepts candidates with degrees in other fields such as biology, chemistry, or computer science. The important thing is to have a strong foundation in science, technology, engineering, or mathematics. This will provide the necessary knowledge and skills to be able to work effectively in a space-related field.

If you're still in high school and considering a career as an astronaut, it's a good idea to take classes in science, technology, engineering, and mathematics (STEM) subjects. This will help you to prepare for a degree in a relevant field and provide a strong foundation for your future studies.

Step 2: Gain relevant experience

To become an astronaut, you need to have relevant experience in your field. This can include working as a pilot, a scientist, an engineer, or in any other job that requires technical skills. You should aim to gain experience that is relevant to space exploration such as working with robotics, doing research in a laboratory, or flying planes.

One of the best ways to gain relevant experience is to work with NASA in a related field. This could involve working on a NASA mission, working as an intern, or participating in a NASA research project. These opportunities can provide valuable experience and help you to build a network of contacts within the industry.

Step 3: Apply to NASA

Once you have a degree and relevant experience, you can apply to NASA's astronaut program. NASA typically opens applications every few years, so it's important to keep an eye on their website for updates. The application process is extensive and includes multiple rounds of testing, interviews, and medical evaluations.

The application process can take several months to complete. You'll need to submit a detailed application form and provide documentation to support your application. You'll also need to undergo a series of tests and interviews to assess your suitability for the role.

Step 4: Complete astronaut training

If you are selected to become an astronaut, you will need to complete NASA's astronaut training program. This program is designed to prepare you for the physical and mental challenges of space travel. It includes training in spacewalking, operating spacecraft, and living and working in space. Astronaut training can take up to two years to complete.

The training program is intense and includes both classroom and hands-on training. You'll need to be physically fit and mentally prepared for the challenges of training. It's important to be dedicated and focused during this time as the training is designed to prepare you for the rigors of space travel.

Step 5: Participate in space missions

Once you have completed astronaut training, you will be eligible to participate in space missions. These missions can range from short trips to the International Space Station to longer missions to the moon or Mars. Astronauts must be prepared to spend extended periods of time in space and be able to handle the physical and mental challenges that come with it.

Participating in a space mission is an incredible experience. It requires teamwork, dedication, and a strong work ethic. Astronauts must be able to work in a confined space, often for extended periods of time, and be able to adapt to new environments and situations.

Step 6: Maintain physical and mental fitness

Maintaining physical and mental fitness is essential for astronauts. They must be in excellent health to handle the demands of space travel. Astronauts undergo regular medical check-ups and fitness evaluations to ensure they are healthy and prepared for their missions.

Astronauts also undergo psychological evaluations to ensure they are mentally prepared for the challenges of space travel. The isolation and confinement of space can take a toll on mental health, so it's important for astronauts to be mentally strong and resilient.

Step 7: Continue learning and developing skills

Space exploration is a constantly evolving field, and astronauts need to stay up to date with the latest technologies and techniques. It's important for astronauts to continue learning and developing their skills throughout their careers. This could involve taking additional courses or training programs, or working on research projects to develop new technologies.


Becoming an astronaut is a challenging but rewarding career path. It requires a lot of preparation, dedication, and hard work, but the experience of space travel is truly unique and awe-inspiring. By following these steps, you can increase your chances of becoming an astronaut and contributing to the exploration and understanding of our universe. Remember to stay focused, work hard, and never give up on your dreams.
