What will happens if an astronaut dies in space?

Nothing really would happen.\nThe side of the astronaut facing the sun would be extremely hot, the side facing away from the sun would be very cold, probably even frozen.\nThe astronaut's body would be hit by small bits of flying rock and space dust.

I woke up to a news report on the radio about how NASA had lost contact with their shuttle, and there had been reports of falling and burning debris. I was sad.\nHonestly... We should be surprised that things don't go wrong more often. Launching into space is a delicate and dangerous venture. There are far more people who are killed each year by toothpicks than die for the purpose of space exploration. This is something we should be proud of.

To allow any astronauts  on board to breathe, the cabin would be be pressurized with a breathable atmosphere.  This internal pressure would be greater than the (very tiny) pressure outside the spacecraft.  And just like increasing the pressure inside a balloon by blowing into it causes it to expand, this increased pressure inside the spacecraft would, if there was a catastrophic failure of some kind, cause the space craft to explode rather than implode.  The exact opposite happens to submarines that are deep underwater.  If something happens to a submarine at depth, it will implode as the pressure of the water around it is greater than the pressure of the interior spaces.

I got only one for you. The risk of entry is burning up in\nthe atmosphere. To steep and it Will burn up. To shallow and they skip off the atmosphere back into space.

The Astronauts were exposed to the radiation not only \nas a consequence of pasing through the Van Allen Belt \nbut also being exposed to the radiation from the Sun.\nThe amount of radiation would have certainly been lethal had they spent more time in space than they did.\nBut for the up to eight days the Astronauts spent\nout of the protective cocoon of Earth's natural \nradiation shield the astronauts were not in any real danger. On the other hand,the danger of a sudden major solar flare-up resulting in radiation exposure so intense to have killed the astronauts in space was  always a possibility.

No one really knows, being an astronaut my self, and wroking with NASA,  none of us really know. the universe is full of things and we haen't explored that yet. Maybe in a million years will that answer be answered.

I'm not sure I understand the question.\n\nBut if the spaceship is travelling at a certain speed - relative to the Earth - then so is the astronaut. So when he gets out of the spaceship his/her speed *relative to the spaceship* is about zero. They travel together, in other words.\n\nIf there were friction things would be different. That is why if you try to walk on the wing of a 747 you will not remain travelling with the plane for very long.

Hope this helps...\n\nAstronaut Requirements\n\n  \n\n \nHave you ever wondered if you have what it takes to become a NASA Astronaut? The term "astronaut" derives from the Greek words meaning "space sailor," and refers to all who have been launched as crew members aboard NASA spacecraft bound for orbit and beyond. Since the inception of NASA's human space flight program, we have also maintained the term "astronaut" as the title for those selected to join the NASA corps of astronauts who make "space sailing" their career profession. The term "cosmonaut" refers to those space sailors who are members of the Russian space program. \n\nThe crew of each launched spacecraft is made up of astronauts or cosmonauts drawn from the various categories described in these pages. The crew assignments and duties of commander, pilot, mission specialist, or payload specialist are drawn from the NASA professional career astronauts. Mission Applicants for the Astronaut Candidate Program must be citizens of the United States.  \n\nPilot astronauts serve as both Space Shuttle and International Space Station commanders and pilots. During flight, the commander has onboard responsibility for the vehicle, crew, mission success and safety of flight. The pilot assists the commander in controlling and operating the vehicle. In addition, the pilot may assist in the deployment and retrieval of satellites utilizing the remote manipulator system, in extravehicular activities, and in other payload operations. \n\nBasic requirements for an Astronaut Pilot include the following: \n\n1. Bachelor's degree from an accredited institution in engineering, biological science, physical science, or mathematics. An advanced degree is desirable. Quality of academic preparation is important. \n\n2. At least 1,000 hours pilot-in-command time in jet aircraft. Flight test experience is highly desirable. \n\n3. Ability to pass a NASA space physical which is similar to a military or civilian flight physical and includes the following specific standards: \nDistant visual acuity: 20/100 or better uncorrected, correctable to 20/20 each eye. \nBlood pressure: 140/90 measured in a sitting position. \nHeight between 64 and 76 inches. \n\nMission specialist astronauts work with the commander and the pilot and have overall responsibility for coordinating operations in the following areas: systems, crew activity planning, consumables usage, and experiment/payload operations. Mission specialists are trained in the details of the onboard systems, as well as the operational characteristics, mission requirements/ objectives, and supporting equipment/systems for each of the experiments conducted on their assigned missions. Mission specialists perform extravehicular activities (EVAs), or space walks, operate the remote manipulator system, and are responsible for payloads and specific experiment operations.\n\nMission specialist astronauts, working with the commander and pilot, have overall responsibility for the coordination of Shuttle operations in the areas of crew activity planning, consumables usage, and experiment and payload operations. Mission specialists are required to have a detailed knowledge of Shuttle systems, as well as detailed knowledge of the operational characteristics, mission requirements and objectives, and supporting systems and equipment for each payload element on their assigned missions. Mission specialists will perform extravehicular activities, payload handling using the remote manipulator system, and perform or assist in specific experiment operations.\n\n\nBasic requirements for a Mission Specialist include the following: \n\n1. Bachelor's degree from an accredited institution in engineering, biological science, physical science, or mathematics. Degree must be followed by at least three years of related, progressively responsible, professional experience. An advanced degree is desirable and may be substit

You can't fall if you're in space, because there is no gravity, which is required in order to fall.  If you're in an atmosphere or using centrifugal force to simulate gravity, then you would still fall, but at a slower rate than you would on earth, assuming there is less gravity.

The effect of weightlessness is due to the fact that the astronaut is falling towards the Earth at the same rate the spacecraft is falling.  I use the term "falling" because the spacecraft, and astronaut are both being accelerated towards the earth.  The reason they remain in orbit is because they have momentum perpendicular to the Earth.  So, like a weight tied to a rope being swung in a circle, the weight is constantly being pulled towards the center of the circle, but never actually moves to the center.  Likewise, the astronaut is pulled towards the Earth, but does not fall into the earth.

Yes, If the mass of the everything doubles than whole universe will get shrunk and the heavenly bodies in the space will collide and get destroyed. because more the mass more the gravitation force. chances gettin hitted by a asteroid will increase. People will find difficult to walk, aeroplane will crash down and satellites may fall down. we've to give the rockets more spped currentl which is 11.2 km/s. so many things happen.

Since its a manned flight, the space craft being heavier, it would take at least eight months or more. However, like correctly pointed out by Christoph... N, it would be a very painful ride for the space passenger. The radiations and the athropy of the muscles & bones would cause a lot of discomfort.

Astronauts - Glenn, Schirra, and Carpenter. The other dead are, Grissom, Cooper, Slayton and Shephard.

The astronaut actually has to pass his own gas to stay warm in space :).. \nok seriously To work in the open cargo bay of the space shuttle or in space, astronauts wear the shuttle extravehicular mobility unit (EMU) spacesuit and they are kept warm by their own bodies heat because of the well insulation and design of the EMU

I believe that blood themselves would simply die out (blood is a living thing!).  When you get a nose bleed, the blood that first comes out is red.  But when the blood dies, it turns darker.  So blood in space will probably be darkish red.

I guess it would explode because of the difference in pressure... but then again this is with a live human... not sure about the dead one.\n\nThis site might be of help:\nhttp://en.wikipedia.org/wiki/Human_adaptation_to_space
