Careers In Space: How To Become An Astronaut?

How To Become An Astronaut?

Definition of “astronaut” is “sailor among stars.” An astronaut is a person who participates in a space programme and is particularly prepared and outfitted for space travel. NASA, also known as the National Aeronautics and Space Administration, has employed astronauts as a component of the American space programme since 1959.


Any crew member of a NASA spacecraft or a member of the NASA Astronaut Corps is referred to as a “astronaut” by NASA. From a wide range of applicants with various backgrounds, NASA chooses astronauts. Only a small number of applicants are selected for the rigorous astronaut candidate training programme out of the thousands that apply.

Although there is no minimum age requirement, American astronauts typically range in age from 26 to 46, with an average age of 34. A 16-year-old female candidate who is preparing for a mission to Mars is the youngest candidate admitted.


Career in Space: Top 8 Space-Related Career Opportunities

Astronauts are the first occupations that come to mind when we think about jobs in space. They are the most well-known space workers, which explains why. It is crucial to remember that large teams of people with a diversity of technical abilities are necessary for space missions to succeed. Some of the tasks of working in space include researching how gravity affects humans, creating powerful telescopes, and making scientific discoveries more understandable for the general public. These are some of the positions that individuals can hold in space.


Use telescopes or tools from space to observe celestial objects, such as planets and galaxies. They gather information, watch astronomical events, and get a deeper understanding of the cosmos.

Atmospheric Scientists 

Utilizing weather balloons, radar systems, satellite photos, etc., analyse weather data and create forecast reports. They also forecast natural occurrences like auroras.

Aerospace Engineers

Create, construct, and test spacecraft and missiles. They design instruments and spacecraft that enable space exploration while taking into account the environmental difficulties.

Mechanical Engineers

Join forces with other engineers and technicians to create the mechanical systems, sensors, and engines that support space machines.

Avionics Technicians

Pay attention to the spacecraft’s navigation and communication systems. They also set up and test equipment, fix broken components, and record the systems for later use.


on missions, take images of space. This entails documenting the findings made while conducting space research and maintaining project records during the entire trip.

Technical Writers

Work with experts to simplify difficult information so that readers can more readily understand the scientific findings.


A career in space sciences is both fulfilling and difficult. It entails working as a team on challenging missions that test the limits of science and technology. The stress of the job is increased by the enormous changes the human body experiences in space. Minor errors can occasionally result in the loss of life and money. In order to succeed in their chosen fields of work, scientists and engineers must also stay on top of innovation.

How To Become An Astronaut All Want to know?

Follow these steps if you want to become an astronaut

1  Create a plan that includes school and experience

Make a career plan first. There are two types of astronauts: civilian and military. Both military and civilian astronauts should have graduate degrees in technical academic fields such biological physical science, science, computer science, or engineering, according to the criteria outlined above.


If you choose the military path, you will be prepared to finish your study there. Numerous federal initiatives, such the Post-9/11 GI Bill, as well as academic institutions like the U.S. Air Force Academy, provide access to higher education courses.

Civilians who have completed a master’s degree in one of the aforementioned programmes, who are licenced physicians, or who have completed two years of doctoral study in a STEM discipline are eligible to apply.


After earning a degree, you’ll need either relevant work experience or flight time. The military might take your experience and education into account if you enrol in the astronaut programme after enrolling. Most astronaut pilots have served in the military, logging numerous hours of training and mission completion.

2. Get In Peak Physical Shape

Astronauts must maintain good physical health since they must meet demanding physical requirements. To get yourself ready for the challenges of the job and the physical screening criteria, you should prioritise your health and fitness if you’re training to be an astronaut.

3. Apply for NASA’s Candidate Selection

Apply for NASA’s candidate selection whenever you’re confident that you can meet the physical, academic, and experience requirements. According to NASA’s website, the application evaluation procedure can normally take up to 60 days, so don’t be concerned if you don’t hear back right away. Make sure you have given every test and screening your best effort because NASA astronaut openings are extremely competitive.

4. Train for flight

Before you embark on a flight mission, astronaut candidates must successfully complete extensive mission training. Two years are required for basic training, which is primarily classroom-based and covers topics like learning about space stations, vehicles, and equipment Similar to military training, astronauts must also take outside-the-classroom survival training.

The mission is chosen and new astronauts are partnered with seasoned astronauts during the second training phase. To learn how to properly launch a mission, pre-launch activities, entry into orbit, and other topics, new astronauts are placed in groups alongside their more seasoned counterparts.

When astronauts are given crew and mission assignments, advanced training takes place. It lasts for ten months and includes training for your particular position as a member of the bigger team.
