How deeply punctured? If it were to be punctured all the way through to the inside of the suit, the answer is No, you could not survive the freezing, airless vacuum of space. Your body couldn't even hold itself together in that environment without the protection offered by the space suit, which is made to provide not only oxygen, but air pressure, radiation, micrometeorites travelling at insane speeds, and heat. If your suit gets punctured, you are dead. If even a tiny bit of air pressure leaked out of your space suit, as it did during the first space walk by cosmonaut Alexei Leonov, you would be crippled with Decompression Sickness, or what is otherwise called "the bends": the gases in your blood would rush from your previously pressurized suit into the unpressurized expanse of space, and... Well, have you ever shaken a bottle of Coca-Cola and then opened the lid? In this metaphor, your body would be the bottle, the Coke would be your blood, and the bottle cap would be your space suit. Yank the cap off, and the Coke explodes out; loosen the cap just a tiny bit, and the soda won't explode, but it will still start to bubble and fizz. Now imagine that bubbling and fizzing going on inside your body... under your skin... in your heart and brain... Not fatal, but very, very painful, and the only treatment is quick, hours-long confinement in a special, pressurized chamber.

US astronaut Eugene "Gene" Cernan (Apollo 17) was 82 years old when he died on January 16, 2017 (birthdate: March 14, 1934).

He was the last US astronaut to walk on the Moon, on December 14 (UTC), 1972.

They breathe artificial "air" that is almost the same as the air on Earth. It is made up of 20% oxygen and 80% nitrogen similar to the air we breathe and it is at a pressure of 14.7psi which is the same as the atmospheric pressure on earth.

Most space exploration is conducted with uncrewed spacecraft due to the high costs and risks associated with human life in space. Uncrewed missions can be designed to endure harsh environments and operate for extended periods without the need for life support systems. Additionally, these missions allow for the exploration of distant or hazardous locations that would be too dangerous for astronauts, maximizing scientific returns while minimizing risk.

People who are selected to go into space must meet certain requirements to go. It also depends on what they will be going to do up there and if they have the best qualifications in a field that is needed.

In the movie "The Martian," no astronauts die during the main events of the film. The story focuses on astronaut Mark Watney, who is stranded on Mars and must survive until a rescue mission can reach him. Although there are tense moments and challenges faced by the crew, all astronauts from the Ares 3 mission survive.

Astronauts use a torch in space primarily for visibility in dark areas, such as during spacewalks or inside spacecraft where lighting may be insufficient. The torch helps them inspect equipment, navigate, or perform repairs in low-light conditions. Since space is devoid of atmosphere, astronauts typically use torches designed for vacuum and extreme temperatures, ensuring reliability and safety during their missions.

Although cosmonauts in the 1960s have said that this was a clear aim of the Soviet space administration, it was the amount of money that it cost that made it impractical for them. This was made clear by the continued failure of the N-1 moon launcher; lack of resources was the reason.

because there is no air in space plus the temperature is hi or low that could freeze you instantly or evaporate you so that's why

In space, an astronaut's sweat does not evaporate as it would on Earth due to the lack of gravity. Instead, it can form floating droplets that cling to the skin or equipment. Spacecraft are equipped with ventilation systems to help manage humidity and moisture, allowing sweat to be absorbed or circulated away. Proper hydration and moisture management are essential to ensure astronauts remain comfortable and healthy during their missions.

Well, to explore space ofcourse. Astronauts go to space to find new planets or such. They observe what is happening.

Neil Armstrong and Edwin Aldrin landed on the moon on a 20/7/1969. It was a Monday.

To an astronaut in a space craft, the sky appears to be black.

No they do not.

They have nothing to fight on the moon!

If anything was left floating freely in the cabin, it would crash to the ground and possibly be damaged.

Astronauts bring tanks of oxygen with them when they go into space. The space suits they use to make space walks also have small oxygen tanks on them.

Eight Canadian astronauts have been to space on U. S. NASA Space Shuttles or Russian Soyuz rockets. These astronauts were Roberta Bondar, Marc Garneau, Steve MacLean, Robert Thirsk, Bjarni Tryggvason, Dave Williams, Julie Payette, and Chris Hadfield.

Apollo astronaut Frank Borman is 90 years old (birthdate: March 14, 1928).
