Otolaryngologists are in high demand.
Astronauts - conduct experiments and maintain the space station. Engineers - design and build equipment for experiments and spacecraft. Biologists - study the effects of space travel on living organisms. Physicists - conduct experiments to understand the fundamental laws of nature in microgravity.
It helps scientists know how much of what is needed to make for example the fuel or how much of gases they need to give the astronauts oxygen.
space shuttles
it is so very dangerous to travel if it is not tested by the scientist
So that scientists could investigate the biological effects of space travel without risking the lives of humans.
No, they don't. There is so many (beyond numbers) galaxies that it is impossible to know everything.
A monkey is close to a human so it was to see how a human type system would react into space. Plus, if there had been an accident a monkey would have been lost and not a human. Monkeys can also be trained to do things that would be needed as well.
American space scientists and explorers are often referred to as astronauts. These individuals are trained to travel into space, conduct experiments, and contribute to our understanding of the universe. They play a crucial role in advancing space exploration and technology.
Astronauts use instruments that are designed to travel in space and withstand extreme temperatures. Some of these kinds of instruments include a pistol grip tool, a robot crane, safety tethers, and a trace gas analyzer.
A spacecraft capable of withstanding extreme temperatures and high speeds, such as a space shuttle or a spaceplane, would be needed for travel in the thermosphere. Traditional aircraft are not generally used for travel in this region of the atmosphere due to its thin air density and extreme heat.
Space stations are crucial for advancing space travel as they provide a platform for long-duration human habitation in space, allowing scientists to study the effects of microgravity on the human body. They serve as laboratories for conducting experiments that can lead to breakthroughs in technology, medicine, and materials science. Additionally, space stations act as logistical hubs for missions to the Moon, Mars, and beyond, facilitating the testing of life support systems and other essential technologies needed for deep space exploration.
No. All E-M waves travel through space at the same speed, known as the"Speed of Light".
