A citizen, military personnel, or student who wishes to become an astronaut must have a bachelor degree from a reputed institution in any field of Engineering, Mathematics, and/or Science. Aeronautical engineering, applied science and astronomy are all well qualified degree programs. The field of study depends on the wish of the student and the needs of the space program. He or she should have a keen interest in the subject he or she has chosen. Quality grades and good aptitude skills are also required besides the basic certification. Higher the qualifications, the better the chance of being selected. Having a Master's degree or Doctorate degree also adds to the chances. The selection panels cross checks a person’s background in terms of education. So courses must be taken from a certified university or institution.


2.   Mandatory work experiences


A person with a needed degree must have a work experience in a professional field for a minimum of 3 years or 1000 hours of pilot in command in jet aircraft if he is from a military background.

Blood pressure must be below the range of 140/90. There must be no physical impairments and the appropriate height must be within 62 to 75 inches when standing.


4.   Age restrictions


There are no particular age restrictions. Astronauts ranging from various ages have been selected earlier and so the age factor is not at all considered as a matter of importance.

Any person can apply for the astronaut candidate program but his country must have a specialized space agency such as NASA in The United States. Many space agencies allow candidates of other nationalities to join. They are considered as international astronauts.

Training is toughCredit:

Very stringent screening is involved in selection and it is here that the candidate must utilize his entire learning, the knowledge he gained from school and colleges. Tough preparation for the selection interview must be carried out by the candidate in order for him to tackle it. The officials check the capability of the candidate and also test their skills in every possible manner.

Once selected, the applicant would be asked to attend an astronaut candidate training program. Usually candidates are selected in separate batches. The selected candidates can earn high salaries and other benefits for training too.


Astronaut Candidate Program


The astronaut candidate program is mainly intended to develop and improve the skills of the selected candidates further through continuous training programs. The astronauts have to carry out all the on-orbit operations, maintenance jobs, robotics task and other experiments on future missions. So the training provided by the NASA to its selected candidates involves ways to make them highly efficient in executing their tasks and duties of an astronaut.


The training duration lasts for a minimum of 2 years where they are taught to learn about future missions as an assistant. Special training is provided in all departments to understand and succeed with all matters regarding the mission of the space agency.


Training requires traveling to other countries, to carry out researches and developments. The training program is indeed very tough. Training for flying and underwater diving and swimming test will be carried out.


Final selection as an astronaut depends on the performance of training. Good performance showed in these training programs results in selection. So the candidate must give their maximum output to reach the destination.

The ones who are not selected as astronaut gets other jobs within the space agency as assistants to the astronauts.


After the successful completion of training and selection, the selected astronauts would be considered as a permanent employee with a huge salary and great benefits.
