The 10 main facts The first person to travel to space was Yuri Gagarin, from the Soviet Union, who orbited the Earth in 1961.The first man to walk on the Moon was an American named Neil Armstrong in 1969.The Moon is the only place in space other than Earth where humans have ever set foot. It was during the Apollo 11 mission that they were going to try to take two men to the Moon. The rocket will travel 17,600 miles per hour to be able to orbit the Earth. Space is very cold and is around -270.45 degrees Celsius.
The longest time spent in space is 437 full days. We'll go into more detail in another section on space travel with telescopes and how telescopes were invented to aid space exploration. However, let's delve into the infinite possibilities of space travel. It's very difficult to explain all the concepts of space travel without being an expert in space, which is why people from space agencies such as NASA (National Aeronautics and Space Administration) spend their entire working lives discovering things like these.
So instead of getting everyone involved in this, let us simply explain space travel to them. Usually, this is how space travel works, it's much more complicated than what is simply explained here on this website. However, you must understand the concepts of space travel as we now know them. When was space travel first thought of? Q.
What is the name of the US agency that focuses on space travel? In the 2000s, China, Russia and Japan planned manned space missions, while the European Union advocated manned missions to the Moon. For a space shuttle to break free from Earth's gravity, it has to travel at a speed of 15,000 miles per hour. NASA, the American space agency, is an acronym that stands for National Aeronautics and Space Administration. Private interests are promoting space tourism and public exploration of the Moon, and SpaceX is developing a reusable orbital launch vehicle.
The lack of gravity can cause blood vessels to thin while the astronaut is in space, which can cause major health problems when the space traveler re-enters the Earth's atmosphere. But has it happened? Perhaps the best candidates are Jan Davis and Mark Lee, sweethearts from training camp, who married shortly before traveling to space together in 1991.On board the space station, two astronauts sleep in small crew cabins at one end of the station, while the third gets into a special space sleeping bag at the other end of the station. And instead of governments being the only actors in space, private companies are now joining this effort. However, if you wanted to go even further into space, outside of Earth's gravity, you'd have to travel even faster.
Since the Gemini flights were much longer than the previous ones, NASA finally had to deal with feces in space. This could significantly increase the ability of space missions to be self-sufficient, which would help with long-distance hikes. This last group includes two seven-person crews aboard the space shuttles Challenger and Columbia, which were destroyed during an atmospheric flight.
