What would happen if someone took of their space suit in space?

1. all of the gasses in your body would collect and violently diffuse out of your body. Its kind of like getting the bends but a thousand times worse and a bit more explosive. you not only need air to breath but you need the pressure to be maintained outside to keep your insides inside. IOW you die within seconds.

2. if you are in a matterless part of space you would be susbjected to an immediate deep freeze. 0 Kelvin cold, like really, really, really cold. cold enough to slow your molecules to a crawl and then grind them to a halt.

2.5 if you are say near a nice friendly star you could be half baked, the part facing the star would be bombarded with a nice spectrum of stellar radiation and cooked at thousands if not millions of degree depending on how close you are. while the other side not faceing the star would remain frozen, in space no atmosphere, so molecules only move if there is an energy source to move them.

3. your corpse will float on in the world indefinately, breaking down very slowly over billions of years via contact with various matters and energies eventually being broken down to its base elements or even subatomic particles and becoming part of the creation of some star or planet of some other thing.

circle of life baby...

conclusion: you would die and become space dust.

What planets have astronauts touched?

Astronauts have landed on the Moon, which is not a planet but a natural satellite of Earth. Humans have not yet landed on any other planets in our solar system.

What would happen if an astronaut's suit were black?

If an astronaut's suit were black, it could absorb more heat from the Sun, potentially making the astronaut inside the suit feel very hot. This could lead to overheating and discomfort, especially during spacewalks or in direct sunlight. Astronaut suits are typically designed with reflective materials to help regulate temperature and protect the wearer.

Do astronauts feel the moon rotating?

No, astronauts do not feel the moon rotating because it rotates at the same rate that it orbits the Earth, keeping one side always facing us. This means that the visible side of the moon remains relatively still from the perspective of someone on its surface.

How does the coriolis effect affect astronauts in space?

Because astronauts orbiting the earth rotate around it much faster than the rest of us (once every 90 minutes or so rather than once a day) the effect of the Coriolis effect would be correspondingly stronger. Ordinarily, this force would still be too weak for astronauts to notice. However, because astronauts feel "zero gravity" (because they are falling towards the earth at the same rate as their ship) there are some situations in which the Coriolis effect might be more obvious to them; for example, objects floating in midair might slowly float back and forth* with a period equal to the ship's orbit time.

*Technical discussion follows* Objects would actually follow elliptical or sinusoidal paths, and this floating effect would actually be a combination of three different effects: the Coriolis effect, along with the "centrifugal force", and the actual gravity of the earth. Whereas the Coriolis force depends on the velocity of a moving object, the last two effects vary slightly according to the radial distance from the center of the earth, and would therefore be most noticeable above or below the center of gravity of the spacecraft. For example, an astronaut resting above the spacecraft's center of mass would first begin falling (very slowly) towards the earth due to the decrease in centrifugal force with greater turning radius. Once moving, the astronaut would be affected by the Coriolis force, and pushed (very slowly) towards the front end of the spacecraft. Maximum drift speeds wouldn't exceed 1 cm/s for the even the largest rooms in the international space station.

That said, I'm not an astronaut, and I don't know if astronauts have ever noticed this faint effect or not. I just did the math.

What uniform do astronauts wear?

Astronauts wear specialized spacesuits called Extravehicular Mobility Units (EMUs) when conducting spacewalks outside of the spacecraft. These suits are designed to protect astronauts from the harsh conditions of space, including extreme temperatures and micrometeoroids. Inside the spacecraft, astronauts typically wear more comfortable clothing, such as shirts, pants, and socks.

How do astronauts control the temperature in there space suits?

Astronauts control the temperature in their space suits using a liquid cooling and ventilation garment (LCVG) system. This system circulates water through tubes in the suit to regulate temperature. Astronauts can adjust the flow of water to maintain a comfortable temperature.

When astronauts go outside of a shuttle in space its called and Eva what does Eva stand for?

EVA stands for Extravehicular Activity. It refers to any activity conducted by an astronaut outside of their spacecraft while in space. During an EVA, astronauts often perform tasks such as repairs, maintenance, or scientific experiments.

Do astronauts lose their memory when weightless?

No, astronauts do not lose their memory when they are weightless in space. However, some astronauts may experience temporary cognitive changes due to factors such as radiation exposure, sleep deprivation, or stress, which could affect their memory.

Do astronauts have to pass any tests?

In the US, you would need to conduct:

-An Interview

-Medical examination

with NASA in order to be able to enter the "training" program for astronauts.

In addition, you would need a college degree as well as filling out a form with high competitiveness( more than 4000 applicant against 20 spots each 2 years)

Is Julie Payette the astronaut dead?

No. Julie Payette is still alive to this day. (Nov.14 2012).

How do astronauts keep their food fresh in space?

Astronauts use special packaging and processes to ensure food stays fresh in space. Foods are dehydrated, vacuum-sealed, or thermally stabilized to prevent spoilage. Refrigeration is not possible in space, so food must rely on other methods to stay fresh.

Who was the first American astronaut to go around the Earth?

The first American astronaut to orbit the Earth was John Glenn. He orbited the Earth three times on February 20, 1962, aboard the Friendship 7 spacecraft.

Why do we experience weightlessness in space?

We experience weightlessness in space because we are in free fall around the Earth, falling at the same rate as the spacecraft we are in. This creates the sensation of "floating" because there is no support force acting against gravity.

What design features of canadarm2 have made space repairs safer for astronauts?

Canadarm2's ability to reach various areas of the International Space Station without the need for astronauts to venture out on spacewalks has made space repairs safer. The arm's precision control and advanced safety mechanisms also help astronauts perform the repairs from a safe distance, reducing the risk of accidents. Additionally, the arm's ability to move heavy equipment and components with ease allows for efficient repairs without requiring astronauts to exert themselves in the vacuum of space.

Why do people want to become a astronaut?

People may want to become astronauts because of a desire for exploration and adventure, a fascination with space and science, a desire to push the boundaries of human knowledge and capability, or a passion for contributing to humanity's understanding of the universe.

How do astronauts exercise in a space ship?

omg they go in a sleeping bag and they freakin tape their selves to the wall in a space ship do you peeps understand. for exercising they use only one tool the ergeometer witch they need to do for two hours.

What are some of the challenges astronauts face living in microgravity environment?

Some challenges astronauts face in a microgravity environment include muscle atrophy and bone density loss due to lack of weight-bearing exercise, fluid redistribution leading to changes in blood pressure and vision, and the potential for motion sickness. They also must adapt to eating, sleeping, and performing everyday tasks in a weightless environment.

Do astronauts keep their quarters clean?

Yes, astronauts are expected to keep their quarters clean and organized just like any other living space. This helps to maintain hygiene, prevent the spread of germs, and promote a healthy living environment while in space. Regular cleaning schedules are established to ensure the quarters remain tidy.

What is the biggest disqualifying factor for prospective astronauts?

The biggest disqualifying factor for prospective astronauts is usually medical conditions that could pose a risk to their health or safety in space, such as significant heart conditions, vision problems, or chronic illnesses. Additionally, a lack of relevant education or experience, or failure to meet physical fitness requirements, can also be disqualifying factors.

What is the dress of astronauts called?

The dress of astronauts is called a spacesuit. It is a specialized garment designed to protect astronauts from the harsh conditions of space, including temperature extremes, microgravity, and lack of atmosphere.

Who wrote song about Alan B Shepherd Astronaut?

The song "She Blinded Me with Science" was written by Thomas Dolby and is not specifically about Alan B. Shepard. However, the music video for the song features a cameo appearance by astronaut Dr. Magnus Pyke, who might be the source of confusion.

Why is Dr Robert Thirsk well known?

Dr. Robert Thirsk is well known for being a Canadian astronaut who made history by becoming the first Canadian to fly two space missions. He has spent a total of 206 days in space across his missions on the Space Shuttle and the International Space Station. Thirsk's contributions to space exploration and science have made him a respected figure in the field.

Why do astronauts wear spacesuits in the outer space?

Astronauts, Or Cosmonauts if you're Russian, Wear spacesuits in outer space because there is no Oxygen to breathe out in the inky vacuum of space. It is also very cold in space and the suits help keep the astronauts warm,they also offer various facilities for an astronaut. Such as communication devices to speak to each other or to their ship or base back on earth.

What did astronauts eat during the mercury project?

Astronauts during the Mercury project ate freeze-dried food, such as chicken stew and beef pot roast, that was rehydrated with water. They also consumed bite-sized cubes of food wrapped in edible gelatin coating to prevent crumbs in the spacecraft.
