What does a rocket scientist do?

Question

what exactly do they do?

Answer 1

they practice the science of rockets....?

Answer 2

they are making rockets to help astronauts

Answer 3

make rockets.

Answer 4

Actually, they are more engineers than scientists.  What they do is design and build rockets, rocket engines and payloads.

Answer 5

Rocket science is an informal term for aerospace engineering especially as it concerns rockets which launch spacecraft into or operate in outer space.

it requires skill in mechanics (fluid mechanics, structural mechanics, orbital mechanics, flight dynamics), mathematics, control engineering, materials science, aeroelasticity, avionics, reliability engineering, noise control and flight test)

Answer 6

design rocket and plan space trips

Answer 7

develop new rocket fuels and designs

Answer 8

Rocket science is an informal term for aerospace engineering especially as it concerns rockets which launch spacecraft into or operate in outer space.

Due to the complexity and depth of this area of engineering (requiring mastery in subjects including mechanics (fluid mechanics, structural mechanics, orbital mechanics, flight dynamics), mathematics, control engineering, materials science, aeroelasticity, avionics, reliability engineering, noise control and flight test), it is also informally used, much like brain surgery, as a term to describe an endeavor requiring great intelligence or technical ability. More often, the term is used to describe an endeavor that is simple and straightforward by stating that the aforementioned endeavor "it's not rocket science".

So, rocket scientist do of which you have read above.

Answer 9

technical he makes an aerodynamic machine which would be able to fly by a the reaction force generated by action of ejection of gases produced (due to combustion of fuel present in the rocket's fuel tank) and he decides where should the rocket fly to so that it can reach a specific location in space with respect to earth and their it can caary on the desired fumigation like launching a satellite
