Astronauts

It is very hard you have to train these this things listed below for years:

How to float in the spacesuit

How to contact the team in earth from space

How to control the heaviness and weight of the suit

How to control the rocket and know what to do if something bad happens

Getting used to space food(lol most of it is nasty)

Also how to get oxygen in their suit and the cord that connects them to it

Thats the most i know and if you want to know more just go to astronaut websites :)

They don't. They have just as much gravitational force on them as you and me. The difference is the two initial frames of reference. You and I are being held down to planet. They are "falling" around the planet in an orbital free fall.

If a few trillion atoms of exhaust are shot in one direction into the vacuum of space the rest of the ship wll move in the opposite direction with the same momentum. These are called burns.

An astronaut protects and finds out much about the universe and what it is.

yes they can communicate they have to

During the start and ascent astronauts wear appropriate suits, that also have been made for radiation protection.

On the ISS experiments have been made with dummies in various astronaut suits placed all over station (even outside) and equipped with radiation measuring devices. This was done during the 1990's already (code word: "Matroshka", you will find details in the internet using that word).

On-board and during spacewalks (EVA's) astronauts wear dosimeters that are regularly checked and harmful amounts of radiation never have been found so far. As for now, even a flight to Mars and back (assumed duration: 500 days) would not constitute a radiation risk to the crew.

People survive in space by wearing space suits. The space suits provide them with oxygen and surround them with air. Also, They stay in space ships that keep them safe by keeping them surrounded by air under pressure.

They go to outer space in a spaceship today.

They put some equipment on in a pool to handle preassure without air... Ever seen that spinning machine that looks like a ride for astronauts? It helps with the super motion. That's all I remember about that :)

The 3 astronauts who flew on Apollo 13 were Jim Lovell (Commander), Fred Haise (Lunar Module Pilot), and Jack Swigert (Command Module Pilot). Swigert replaced Thomas "Ken" Mattingly 3 days before the launch of Apollo 13 when it was discovered that the son of Charlie Duke, the backup, had caught the measles. Mattingly had not had the measles before, so he was replaced on the flight by Swigert. Apollo 13 was Swigert's only flight. He resigned from NASA in 1977. In 1982, he ran a successful campaign for House Representative from the state of Colorado. Unfortunately, he died of bone cancer 8 days before he was to be sworn in. Lovell and Haise are still alive.

The first words uttered by a man setting foot on the moon , was "That is one small step for man, a giant leap for mankind."

The first words after landing, but while still in the landing module were "Houston, the Eagle has landed."

The first female astronaut was Valentina Tereshkova and she was from the Soviet Union.

Potential Astronauts should maintain a healthy and proportionate body weight for their frame. There are certain height restrictions (with about 6'4" being the tallest). This puts the maximum weight at around 200 pounds, give or take.

The same amount they need on earth. just because theyre in a different place doesnt mean their needs change. Space99boy: Actually they need slightly more because you grow more in space because there is no gravity.

Cosmenauts

They should go into space so that we know what thngs look like from down here. they shoild also go into space to make history and to bring back diffrent things for lab people to detremen what it is.

During the Apollo missions, the CM and the LM each had a condom-shaped sleeve (technically, each astronaut had their own sleeve, which they would connect to the tube each time they needed to use the bathroom), connected by hoses and a valve to the exterior of the spacecraft. To urinate they slipped the sleeve on, relieved themselves, then opened the dump valve, expelling the urine into space.

To defecate, the astronauts had a sort of top-hat shaped container with an adhesive rim that they would attach to their buttocks, relieve themselves, then remove and seal. The container had a small capsule inside containing the familiar blue chemical found in airplanes lavatories. They would then squeeze the container to break the capsule and mix the chemical with the feces contained in the pouch. These pouches were stored until they could be disposed of back on Earth.

It occurred in late 1965. The US spacecraft Gemini 6, piloted by Wally Schirra, maneuvered within a foot of Gemini 7, which had launched into orbit 8 days earlier, carrying Frank Borman and Jim Lovell. (This was technically the Gemini 6A or "Gemini 76" alternate mission, after an unmanned target vehicle failed to reach orbit. Schirra and Jim Stafford also had a close call when their Titan booster failed at ignition on December 12.)

This rendezvous was on December 15, 1965. Four months later, Neil Armstrong piloted Gemini 8 to a docking with an unmanned Agena spacecraft on March 16, 1966.

plz can you bring up my answer for m question?

apart from being a top class jet pilot priyanka, you need to fulfill some essential requirements of nasa such as being able to live on waterless food for days, being able to work out for a minimum 4 hrs at a stretch, being mentally very very sound (I'll admit some of us get even a bit angry at the smallest provocation). they test you under extremes of psychological stress if you can take sane and swift decisions under such conditions, and like this many other tests. one such is the g-force test. you've to wear a g-suit and sit belted inside a spherical cell. then they rotate you starting slowly first and moving upto 2 revs a sec to test your retaining your consciousness in that circular motion of extreme g stress. most testers pass out at 1.5 revs a sec but that is normal for a human being.

and of course, you do need an opportunity for taking up a pilot career (fighter pilot not commercial) in the u.s. i don't know about the qualifications required for that. you've to ask someone in the Indian air force or from someone who has been or is in the u.s. like sunita Williams. I've a pdf matter that nasa themselves sent my cousin here. it has some questions nasa asks you for taking up a career there as astronaut, flight controller, mission engineer, control technical manager, project director etc. ok, email me bal71dan@yahoo.co.in with your name, age, your special interests in physics, chemistry, biology and math, how much angry you get in a day and how often, how do you get along with your friends etc. if you truthfully answer these questions to me I'll mail you that pdf which i personally guarantee, will kindle such an interest in you that you won't have just a desire to become an astronaut but you'll be seeing in yourself an ever increasing ambition for that. meanwhile study excellent because you need to be an excellent (mind you excellent not just very good) student of physics, math, chemistry and biology as well for attaining the goal of becoming an astronaut.

and remember, the goal is difficult, the path even more, but the desire gives way to ambition which gives way to rage. so have a raging interest and aspire to attain and achieve the best.

There is no air on the moon. Sound waves only propagate through a medium, such as air, water, etc. Sound waves cannot propagate through a vacuum, therefore the astronauts had to use radios to speak to each other.

Astronauts in their spacecraft (such as the Space Shuttle) are lifted into space by huge rockets which accelerate the craft to "escape velocity" (about 25,000 mph). This puts the craft into orbit around the Earth, its forward velocity balancing the continuous pull of gravity. When they are ready to return to Earth, they use rockets to slow down, and gravity pulls them back out of orbit.

When astronauts travelled to the Moon, another smaller rocket pushed the Apollo spacecraft out of orbit, and carried it to the gravitational field of the Moon. Another rocket firing pushed the craft back to Earth.

Unmanned space probes have travelled to even farther distances from Earth, including the outer planets Uranus and Neptune. Most of the travel is coasting, because there is practically no matter in space to slow a spacecraft down.

NASA needed short astronauts due to the size of the capsules. Gus Grissom was 5' 5" (1.65 m).

The suits that the Apollo astronauts wore were not particularly shiny. They were white and reflected the sun's light and heat. The Mercury program astronauts did wear shiny pressure suits made of aluminium-coated nylon, to provide thermal and pressurization protection. They did not, however, go to the moon as their flights were sub-orbital and low-earth orbital.
