How to become an astronaut in India and the USA training requirements and essential steps

The dream of going to space continues to attract applicants around the world, especially with advancements like the Gaganyaan mission and NASA programs. Trained Profissionais travel to the Estação Espacial Internacional (ISS), perform scientific experiments and contribute to the progress of space exploration. Recent Exemplos include Indian Shubhanshu Shukla, who participated in the Axiom-4 commercial mission to the ISS, and Sunita Williams, of Indian origin, who ended a 27-year career at NASA in December 2025 after multiple missions.

There is no specific college to train astronauts, but the path begins early with academic choices focused on science. Após high school, the student must choose a science course with an emphasis on physics, chemistry and mathematics. Esse direction opens doors to degrees in areas such as engineering, physics, biology, chemistry or mathematics, which serve as a solid foundation for a career.

Experts highlight that the profession requires not only technical knowledge, but also intense physical and mental preparation. Astronautas perform complex tasks in space, such as equipment maintenance, conducting experiments and spacewalks, in addition to working on land with continuous training and technology development.

What does an astronaut do on a daily basis?

Astronauts are professionals dedicated to manned space missions. Eles perform scientific experiments, launch satellites, and maintain spacecraft systems. Mesmo outside of space, they participate in constant training, simulate risk scenarios and collaborate with teams on the ground.

The work varies depending on the role in the mission. Alguns focus on technical operations, while commanders pilot space vehicles. Continuous preparation ensures they handle emergencies and maintain high performance in extreme environments.

Academic path at Índia to reach ISRO

The path begins after Year 10, with the choice of the science stream in secondary school. Física, chemistry and mathematics form the essential core for any related degree. Depois, the candidate must have a degree in engineering, physics, biology, chemistry, mathematics or a related field at a recognized institution.

Then, a master’s or doctorate degree in disciplines such as aerospace engineering or STEM fields is recommended. Esses advanced levels increase chances in ISRO selections. Pilotos from Força Aérea Indiana receive preference due to physical conditioning and high pressure experience.

Medical fitness goes through rigorous exams that assess cardiovascular resistance, vision and the ability to withstand acceleration. Altura and weight follow specific limits for compatibility with spacecraft suits and seats.

Selection for mission Gaganyaan and current preparation

Índia advances mission Gaganyaan, with a manned launch scheduled for 2027 after unmanned testing in 2026. Quatro officers from Força Aérea Indiana, including Shubhanshu Shukla, Prashant Balakrishnan Nair,

They underwent intense physical and mental testing, followed by 13 months of training at Rússia. The program continues with advanced simulations and survival techniques. Após the completion of Gaganyaan, ISRO should open wider recruitment processes for future candidates.

Indian citizenship, degree in technical field and relevant experience are basic requirements. Pilotos military personnel stand out for their ability to manage risks and make quick decisions in high-speed and stressful scenarios.

NASA Requirements for International Applicants

NASA requires US citizenship for direct selection as an astronaut. Candidatos need a master’s degree in a STEM field such as engineering, biological sciences, physics, computer science, or mathematics. Experiência profissional mínima de três anos ou mil horas como piloto comandante em jatos de alto desempenho contam como qualificação alternativa.

The process includes medical examinations for long-haul flights, with correctable vision checks to 20/20 and height between specific parameters. Treinamento lasts about two years before assignment to missions. Cidadãos from other countries, including those of Indian origin, only access positions through partnerships or naturalization.

Leadership, teamwork and effective communication complement the technical requirements. The agency values ​​diverse profiles, but maintains strict criteria to ensure safety on missions.

Essential physical and mental preparation

Physical conditioning represents a decisive factor in selections. Pilotos fighters, for example, develop resistance to extreme variations in pressure and acceleration. Eles train to remain calm in situations of imminent risk and make instant decisions.

Medical exams assess stress tolerance, including blood pressure and balance tests. Boa vision and absence of conditions that compromise performance in microgravity are mandatory. Continuous ground training simulates space conditions to reinforce these capabilities.

Astronaut salary and career at Índia

An astronaut at Índia receives an average salary of approximately 90 thousand rupees per month, plus benefits and bonuses. Remuneration varies depending on experience, position and agency. The career offers stability and opportunities to contribute to national space exploration projects.
