Astronaut
it is so very dangerous to travel if it is not tested by the scientist
Astronautics is the branch of aerospace engineering that deals with the design, development, and operation of spacecraft for travel in outer space. It involves the study of the technical, practical, and theoretical aspects of space travel and exploration.
outer space travel work by gravity and friction plus magentism
They travel to outer space
Yuri Gagarin was the first human to travel in outer space on April 12th, 1961
Sound requires a medium, such as air, water, or solid surfaces, to travel through. In outer space, there is no medium for sound waves to travel through, so sound cannot propagate in the vacuum of space.
These are the suits that the astronauts wear when they travel to outer space.
So far, technology has only allowed us to travel to space in rockets/space shuttles.
Valentina Tereshkova (a Russian) was the first woman to travel in space.
the vacuum of space
The science of travelling to outer space could be called space science, could be called rocketry, could be called astronautics.
