Astronauts

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.

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.

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.

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.

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)

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Boredom on a long flight. Loss of muscle mass from lack of exercise. Collision with asteroids, etc. and death. Problems from expecting a manmade space craft to be reliable for months of the trip, breakdowns with no garage to get help.

Astronauts use specially designed toilets that use vacuum suction to collect waste. Solid waste is stored in sealed bags to be disposed of later, while liquid waste is purified and recycled into water. Adequate hygiene is essential to prevent contamination in the closed space environment of the spacecraft.

The planet Mars has seven hills named after the seven astronauts who died in the Colombia space shuttle accident in 2003. These hills were named after the crew members as a tribute to their legacy and contributions to space exploration.

Astronauts typically spend around two weeks in quarantine before their space mission to ensure they are not carrying any germs or illnesses that could affect their health during their time in space. This quarantine period helps protect both the astronauts and their crewmates on the mission.
