Kokila Chokkanathan
Becoming an astronaut is a dream career for many, but it requires a unique combination of education, physical fitness, technical skills, and determination. Here’s a complete guide to pursuing this exciting profession.

1. Educational Requirements

Education is the first step to becoming an astronaut. Most space agencies, including NASA, ISRO, ESA, and others, require candidates to have:

  • Bachelor’s Degree: In engineering, physical sciences, biological sciences, mathematics, or computer science.
  • Advanced Degrees (Optional but Preferred): Master’s or Ph.D. in these fields can improve your chances.
  • Strong academic record in physics, math, and technical subjects is essential.
2. Professional Experience

Space agencies typically require professional experience in your field:

  • Engineers: Minimum of 3–5 years of professional experience in a technical or aerospace-related field.
  • Pilots: For pilot astronauts, a background in military or test piloting is often required, along with thousands of flight hours.
  • Scientists and Researchers: Experience in research, lab work, or field studies related to space, physics, or biology.
3. Physical & health Requirements

Astronauts must be physically and mentally fit:

  • Excellent vision (correctable to 20/20)
  • Good hearing and cardiovascular health
  • Ability to handle extreme environments, high G-forces, and microgravity
  • Psychological fitness to endure isolation and stressful conditions
4. Training & Courses

After selection, astronauts undergo extensive training, which can last 1–2 years:

  • Spacecraft training: Learning to operate spacecraft systems and controls
  • Extravehicular activity (EVA) training: Practicing spacewalks in neutral buoyancy pools
  • Survival training: For landing in extreme environments
  • Simulations & teamwork: Handling emergencies, mission simulations, and leadership exercises
  • Physical training: Strength, endurance, and swimming exercises
Some candidates also pursue aeronautical engineering courses, advanced robotics, or pilot training to enhance their profile.

5. Salary and Benefits

Astronauts are generally well-compensated, but salaries depend on experience and the space agency:

  • NASA: $66,000 – $161,000 per year (GS-12 to GS-13 level)
  • ISRO: Around ₹1,20,000 – ₹2,50,000 per month (varies with rank)
  • ESA & Other Agencies: Competitive salaries with additional allowances for space missions
Additional benefits often include healthcare, insurance, pensions, and international exposure.

6. Career Path

  • Start as an engineer, scientist, or pilot
  • Gain relevant experience in aerospace, research, or defense
  • Apply to a space agency’s astronaut program
  • Complete training and selection process
  • Participate in space missions, research, or satellite operations
Astronauts may also transition to roles in space research, academia, aerospace industries, or leadership positions in space programs after active missions.

7. Tips to Increase Your Chances

  • Maintain excellent academic grades
  • Gain experience in STEM-related fields
  • Stay physically fit and adaptable
  • Learn multiple languages, especially Russian or Japanese, for international missions
  • Participate in aerospace internships, research projects, or astronaut preparatory programs
Becoming an astronaut is highly competitive, but with the right education, experience, fitness, and perseverance, your dream of going to space can become a reality.
