🚀 How do you become an Astronaut?

Becoming an astronaut is a highly competitive and rigorous process, as astronauts are responsible for conducting complex missions in the challenging environment of space. While there is no one-size-fits-all path to becoming an astronaut, there are several common steps and qualifications that aspiring astronauts should consider. Here we have listed a general idea.

Educational Requirements:

Obtain a Bachelor’s Degree: Most astronaut candidates have at least a bachelor’s degree in a science, technology, engineering, or mathematics (STEM) field. Degrees in engineering, physical sciences, biological sciences, mathematics, or computer science are commonly preferred.

Gain Relevant Work Experience:

Gain Professional Experience: ISRO, NASA, and other space agencies typically require several years of relevant professional experience, often in STEM-related fields. This experience could include work as an engineer, scientist, medical doctor, pilot, or other technical roles.

Military Service (Optional): Many astronauts come from military backgrounds and have experience as military pilots or test pilots. Military service can be a pathway to becoming a NASA astronaut, but it’s not the only route.

Develop Skills and Qualifications:

Gain Flight Experience (for pilot astronauts): If you aspire to be a pilot astronaut, you’ll need flight experience. This typically involves becoming a military or civilian pilot with significant flight hours.

Acquire Advanced Degrees (Optional): While not always required, having a master’s or Ph.D. in a relevant field can enhance your qualifications as an astronaut candidate.

Physical and Medical Fitness:

Astronaut candidates must meet rigorous physical and medical standards. Good health, excellent vision, and physical fitness are essential.

Apply to Space Agencies:

Monitor Astronaut Selection Opportunities: Space agencies like ISRO or NASA periodically announce astronaut selection opportunities. Keep an eye on their official websites and announcements for application details.

Prepare a Strong Application: When a selection opportunity arises, submit a thorough and competitive application highlighting your qualifications, experience, and skills.

Be Persistent: The selection process is highly competitive, and many qualified candidates are not selected on their first attempt. Be persistent and continue to improve your qualifications.

Interview and Evaluation:

If your application is successful, you may be invited to an interview and evaluation process, including psychological assessments, medical examinations, and interviews with selection boards.

Astronaut Training:

If selected, you will undergo extensive astronaut training covering a wide range of skills, including spacewalks (extravehicular activities), spacecraft systems, robotics, survival training, and more.

Space Missions:

Once fully trained, astronauts are assigned to space missions, conducting scientific experiments, repairing spacecraft, and performing other tasks in space.

It’s important to note that becoming an astronaut is highly competitive, and only a small number of candidates are selected for each astronaut class. It requires exceptional qualifications, dedication, perseverance, and a passion for space exploration. Additionally, space agencies worldwide have their astronaut selection processes and criteria, so be sure to research and follow the specific requirements of the space agency you are interested in.

Becoming a scientist necessitates a comprehensive educational foundation, starting with excelling in science and mathematics coursework during school. Subsequently, students should identify their field of interest and pursue a rigorous Bachelor of Science degree program at an accredited institution. Graduate education, such as master’s or Ph.D. studies, typically follows, providing specialized knowledge and hands-on research experience. Engaging in original research, publishing findings, networking, and continuous learning are crucial components of a scientist’s academic journey, ultimately leading to contributions to their chosen field of science.

The most popular space agencies


ISRO, the Indian Space Research Organisation, is the space agency of the Government of India, established in 1969. ISRO is responsible for the planning, development, and execution of India’s space exploration missions, satellite programs, and space research. The organization has achieved significant milestones, including launching satellites for communication, earth observation, navigation, and scientific research. ISRO’s successful missions, such as Chandrayaan and Mangalyaan, have garnered international recognition and have positioned India as a major player in the global space community.


NASA, the National Aeronautics and Space Administration, is the United States government agency responsible for the nation’s civilian space program and for aeronautics and aerospace research. Founded in 1958, NASA conducts pioneering research, exploration, and missions in space, including sending astronauts to the moon during the Apollo program and launching numerous robotic missions to study distant planets, asteroids, and celestial bodies. NASA plays a crucial role in advancing our understanding of the universe, Earth’s environment, and the development of space technology that has applications on and beyond our planet. It continues to inspire scientific discovery, technological innovation, and international collaboration in the field of space exploration.


The European Space Agency (ESA) is an intergovernmental organization founded in 1975, comprising 22 European member states. ESA’s primary mission is to advance space exploration, research, and technology development for peaceful purposes. The agency conducts a broad range of activities, from launching Earth observation and communication satellites to collaborating on planetary exploration missions like the Mars Express and Rosetta missions. ESA plays a key role in promoting European cooperation in space endeavors, fostering scientific discovery, and advancing space-related technologies to benefit society.


The CSA, or Canadian Space Agency, is the national space agency of Canada, established in 1989. Its primary mission is to manage all of Canada’s civil space-related activities and contribute to international space exploration efforts. The CSA is known for its contributions to various space missions, including the Canadarm robotic arms used on the Space Shuttle and the International Space Station, as well as its involvement in Earth observation and satellite communications. The agency’s work encompasses space science, research, technology development, and international collaboration in space exploration and research.
