Careers in Space Sciences

Pratibha Mishra

Rakesh Sharma, Kalpana Chawla and Sunita Williams might be the popular faces of space exploration programs but careers in Space Sciences are not only about becoming an astronaut. A space agency employs several other scientists, technicians, and experts you might never have heard of.

Whether you are a man or a woman, Space Science and Technology offers you several job opportunities where you can be a part of making the space science fiction come true.

How does Space Technologies affect Our Lives?

Have you ever wondered why government spends so much on the ventures to the cosmos when it already has so much to do and improve on Earth itself? Well, it is because the advancement of technologies help us know more about our Earth and do things that would have been ‘inconceivable’ otherwise.

From the time astronauts of the Apollo Moon program took the first images of our planet, space exploration programs have helped us to know more about how the Universe works, and how small and delicate our Earth is – in the grand scheme of things.

The satellites we send out in space help us to transmit TV, radio and telephone signals; make satellite navigation systems used by cars and aero planes possible, and offer insights that can help us to take better care of Earth. They allow us to take a closer look at the Earth’s features such as our atmosphere, oceans, rainforests, deserts, ice sheets, weather and cities etc. It is the information sent by satellites that has made it possible for us to understand how pollution from our cars, factories and homes is destroying the Ozone layer, which shields us from the Sun’s harmful ultraviolet rays. It has impressed on us how crucial it is to find and use environment-friendly chemicals and pay attention to the state of our atmosphere too.

The space sector is also the forerunner in developing renewable energy. It employs some of the most energy-conscious scientists on Earth. It was space engineers who first used solar cells to power satellites during their space stints. They are also good at making use of every single watt that powers a spacecraft or satellite equipment. Three areas in Energy Science where space scientists have led the way are:

*Energy Preservation: Satellites were the first to use navigation systems to reach distant satellites or planets in the energy-efficient manner. Today, they help us to find the right sites to install renewable energy hardware, such as solar panels, windmills, etc. They also make telecommunications (and teleconferences) possible, negating the need to travel and making processes faster. All this help us save a considerable amount of energy.

*Energy Storage: Li-on cells that are so commonly used today to power portable devices and electric vehicles is popular in space applications too, as they can store higher energy over mass.

*Energy Transfer: We are already using lasers to transfer energy in the form of ‘microwave rays’ over large distances. Now, space engineers are working on futuristic concepts like transmitting energy from solar arrays to power remote satellites. It is possible that they might be able to direct energy from space to Earth in a few decades.

Satellites also help in weather-tracking and predicting natural disasters. Recently, it was the satellites that warned people about Hurricane Sandy just as it was developing, and allowed people to prepare for it and evacuate vulnerable areas in time. They keep an eye on oceans and have found how the heat stored by them eventually lead to deluge and floods in some part of the world, and cause drought in others.

With the help of satellites, we can now keep an eye on the remote areas of the world too – and study things like depletion of ice sheets, shrinking of rainforests, and possible flooding of coastal areas that are important indicators of Global Warming.

Career Opportunities for those who are fascinated by Space or the Universe

Young graduates who specialize in Space Sciences and Technology often get to work on innovative technologies and space secrets such as:

*developing advanced technical infrastructure needed for space exploration,

*mapping distant planets and stars,

*studying galaxies,

*making new discoveries about the solar system, and

*Studying satellites and how they affect Earth etc.

Yet, for the uninitiated, the first career that comes to mind while talking about Space Sciences is that of an ‘Astronaut’. Here, we will discuss about astronauts and what else space scientists do:


The coveted job of an astronaut has an extremely limited number of opportunities across the world. If you want to be a part of a space exploration program as the ‘astronaut’, you will have to meet the stringent physical fitness criteria and undergo a rigorous training. Competition is fierce, and only the most exceptional candidates make it to the training programme for astronauts.

To become an astronaut, you must have graduated from a field related to Science or Mathematics, and must be an experienced pilot. Most of the astronauts hold Master’s or Doctoral degrees. They also need to meet height and weight requirements, and must be able to see with perfect clarity. Each space agency (like NASA) specifies its own selection criteria which can be seen on its website.

*Space Engineers

While only a handful of people (read astronauts) get to travel in outer space, engineers are the ones who make space exploration possible. They not only design space-crafts, space vehicles and space stations but also space satellites that predict weather and climatic conditions, and facilitate broadcasting and communications.

Diverse engineering streams can lead you into the field of Space Science, such as:

*Aerospace or Aeronautical Engineering

*Avionics & Instrumentation Engineering

*Computer Science and Engineering

*Materials Engineering

*Mechanical Engineering

*Robotics Engineering

*Spacecraft Engineering

*Telecommunications Engineering

Space Scientists

Scientists from diverse streams can make a research and development career in the field of space science. For example, a pharmacology researcher might try to develop new medications with the help of ‘alien’ substances found from a meteor or during space exploration trips. Experts from the following fields can often be seen in space agency labs:

*Astrophysicists: study physical nature of stars and celestial bodies, and how laws of Physics can be applied to astronomical observations.

*Biologists: study alien life forms or possibility of life on other planets.

*Chemists: study chemicals and chemical compositions of meteors and substances found in space.

*Doctors and Medical Scientists: study effects of space travel and extended stay in space on human body, animals and plants.

*Geologists: study geological features of Earth, other planets, and satellites – their physical features, how they were formed, and how different processes act on them.

*Meteorologists: study Earth’s atmosphere and how it gets impacted from outer space.

*Physicists: study Astronomy, Astrophysics, High-Energy Particle Physics, Space Physics, Space Weather, Lighting Research and other planetary sciences.

Space Science is an interdisciplinary field of pure and applied sciences, and includes opportunities for experts of almost all streams.

*Technologist and Technician Positions

Technologists and technicians often work closely with engineers and scientists to build, test and improvise upon various kinds of space projects and technological innovations. Skilled technicians from the following fields are often hired by space agencies:

*Communication Technicians

*Computer Aided Design (CAD) Operators



*Laser Technicians

*Quality Assurance Specialists

*Radar Technicians

*Robotic Technicians

*Satellite Technologists
