The word astronaut comes from the Greek words "space sailor." This describes the astronaut perfectly, a man going on an adventure to discover new things. In space, an astronaut could travel to different places, in this case Mars, to gather samples from the planet, like soil, and when their mission is over they go back to Earth and send it to scientists to study the samples. However, an astronaut's job is very dangerous; even a slight mishap can lead to massive consequences.
Robotics engineers design and develop new robotics technology, create the processes of the robots, and create machines that might build robots. Robotics engineers are a critical piece of sending a man to Mars. They design things such as; the space shuttle, code that runs the space shuttle, and diagnostic code that tells the spacecraft's pilot what might be happening with the spacecraft.
A spacecraft pilot maneuvers the space shuttle. They are key to sending a human to Mars; spacecraft pilots are the individuals who will maneuver the spacecraft to the martian planet. Their job requirements are very strict; they need at least 1000 flight hours, and at least a bachelor's degree in a field relating to space engineering.
A flight engineer is trained to check a plane before take-off before the plane can fly. A flight engineer also controls vital equipment such as air conditioning, engine power, and a plane's electrical system. A flight engineer is not always hands on with an aircraft, some flight engineers check weather patterns to determine the amount of fuel for a flight.
Armstrong's Maintenance Division
The Armstrong Maintenance Division is one of five specialized groups that makes sure that the Armstrong and it's crew safe. This division includes several aspects, including flight line safety, maintenance operations, aircraft parts, and technical data.
