Space Exploration Career Field Structure

Space Exploration CareersSpace exploration draws on a wide variety of technologies, sciences and industries. The exciting images of rockets blasting toward the heavens and astronauts walking through space present only part of the story—thousands of people here on Earth make those missions possible. In total, only 321 astronauts have been selected in the19 groups from 1959 through 2004. Many other professions contribute to space travel efforts, and a career in engineering or science, for example, may present a more realistic option for students determined to enter this field. A seven-day space shuttle mission, for example, is the culmination of months, possibly years of work by hundreds of professionals. Engineers, scientists, technicians, computer programmers, pilots, mechanics, graphic artists, and administrators are only some of the different professionals needed to run this industry, and many work for NASA, the major employer of space exploration professionals.

Aerospace careers specific to space exploration include those in the sciences such as physics and biology. Physics plays an important part in the development of new types of aircraft, weapons, and missiles; chemistry research provides new materials for use not only on Earth but also in space. Biologists explore the effects of speed, gravity, and space on the human body, and may also develop vaccines or medical treatments based on research conducted in space.

Engineers, technicians, and production workers play a major role in space exploration. They conduct studies of the atmosphere and space; improve the usefulness, performance, speed, safety, and efficiency of combat, aeronautical, and space vehicles; and develop and operate vehicles capable of carrying instruments, equipment, supplies, and living organisms through space and through the atmosphere. Aerospace engineers are highly trained scientists who develop, design, and oversee the assembly of all types of aircraft, including space shuttles, missiles, commercial planes, and military jets.

More specialized jobs include the following:

  • applications engineers who analyze the marketplace and help determine which products are needed
  • chemical engineers who design the processes to produce the chemicals and other materials needed by the aerospace industry
  • control dynamics engineers who use computers to design flight control systems and analyze their stability
  • materials engineers who test and analyze various metals, ceramics, plastics, and other materials for the applicability to aerospace manufacture
  • navigation systems engineers who are responsible for the development and testing of navigation, guidance, and control systems applied to aircraft and spacecraft

Astronautical and aerospace technicians assist engineers in the design, construction, testing, operation, and maintenance of air and spacecraft. Such assistance includes preparing drawings, diagrams, blueprints, and scale models of the planned craft.

Astronauts are the pilots and crew of spacecraft. Highly skilled and educated experts in various fields, they are recruited and trained by NASA to perform a range of sophisticated tasks, such as flying the spacecraft, deploying satellites, and performing scientific experiments on animals, plants, and themselves in a gravity-free environment.

Astronomers study the universe and its celestial bodies by collecting and analyzing data obtained through observation and through information obtained by means of spacecraft and Earth satellites. Closely related is the work of astrophysicists, whose investigations focus primarily on studying the physics of the universe. Both astronomers and astrophysicists may apply their findings to aerospace manufacturing and space research and flight.

Each spacecraft is developed differently. NASA may contract with a company or companies to build to their specifications, or a manufacturer may develop a technology on its own and then try to sell NASA on its usefulness. The construction of the space shuttle is a good example. The shuttle’s orbiter was placed under the responsibility of the Johnson Space Center in Texas, and its principal contractor was Rockwell International. The Marshall Space Flight Center in Alabama, meanwhile, contracted with both Morton Thiokol Chemical Corporation and Martin Marietta Aerospace for the shuttle’s solid-fuel booster and liquid-fuel propellant. While there are only 50 or so major aerospace manufacturers, thousands of subcontractors, from very large to very small companies, supply parts, supplies, materials, and subassemblies to the principal contractors. Manufacturers generally compete for contracts for military, commercial, and space aircraft.
