There are a wide variety of space science careers to choose from that involve all aspects of studying the earth, atmosphere, other planets, and the exploration of the universe. NASA provides many employment opportunities aside from becoming an astronaut. As a space scientist, you conduct research and studies in a specialty field such as biology, chemistry, meteorology, physics, geology, or even pharmacology, in which you use substances from space to develop new medications. Engineers have responsibilities including developing advanced technology such as satellites and the spacecraft that make space exploration possible. Specialties as an engineer include robotics, telecommunication, computers, avionics, instrumentation, and more. There are also technologists and technicians whose duties revolve around working with the engineer to test this technology.
