Astronauts

It is really the smell of food that gives it its taste, and because there is little gravity in space, the smell floats away before it is able to get to the astronaut's nose. Astronauts also have to deal with a constantly stuffy nose, which further hinders the ability to taste.

Canadian astronaut Chris Hadfield was born in 1959. After training with the US Air Force, he earned a master's degree at the University of Tennessee Space Institute in May 1992, and was subsequently selected as an astronaut in June 1992. He served as CAPCOM for more than 25 Space Shuttle flights and flew as a mission specialist in 1995 and in 2001. He also commanded the International Space Station for three months in 2013.

Space shuttles and space stations have small waterless shower stalls. There are Velcro straps inside of the shower stall to hold the astronaut inside of the shower. Astronauts wear Velcro-bottomed slippers to attach their feet to a Velcro strip on the bottom of the stall. The astronauts wash their hair and skin using disposable wipes that are specially designed for the space flight. The soap from the wipes does not need to be rinsed off the skin or hair. The wipes are disposed of in a special trash receptacle in the space shuttle or space station. The trash receptacle uses air to pull the waste into an airtight canister.

Some space stations do use small amounts of water in the shower stalls. A small amount of water is released through a hose that is controlled by the astronaut, while air from another hose sucks in the water and brings it to an airtight canister where it will be purified and recycled.

I think it is because the human skeletal system is built to support your weight. Once you have no weight, it stops functioning correctly. Astronauts coming home from the MIR space station had significant bone deterioration after their 6 month stay in space. M uscles don't work as well either, very little energy used to lift stuff in a weightless environment.

The fourth astronaut on the moon was Mr Alan Bean.

It keeps you alive which is generally considered a plus if you have to leave the protection of whatever kind of "space ship" you are in. Space suits are pressurized, keep you warm/cool, and provide breathing oxygen. At altitudes much above 30,000 feet, there isn't enough oxygen to sustain life for very long, and above about 63,000 feet (called the Armstrong Limit), there isn't enough pressure to keep your blood from boiling at body temperature. The latter means that you would explode like an egg in a microwave, but in less time. http://en.wikipedia.org/wiki/Armstrong_Limit

The only place astronauts have been other than Earth, is on the Moon. Between 1969 and 1972 there were 6 moon landings. Nobody has gone to the Moon since then and nobody has gone to any other planets yet. Most astronauts now just orbit the Earth on one of the Space Shuttles or on the International Space Station or one of the other spacecraft that some countries have. It will be a long time before it will be possible to send astronauts to other planets.

The early Soyuz and Mercury astronauts found out that man could survive in space. That meant eating, sleeping, going to the bathroom, and even manipulating the spacecraft in space.

Astronauts on both sides of the Space Race found out in the mid 1960s that man could work outside the spacecraft with proper restraints. Gemini astronauts performed the first rendezvous and docking in space, an important milestone in reaching the moon.

The Apollo astronauts achieved the first manned flight to the moon, showing that man can survive a trip through the Van Allen Belt. Apollo 11 showed man could land on the moon and return safely to the earth.

Astronauts on Soviet space stations, Mir, Skylab, and the Space Shuttle showed that man can survive in space for months at a time. They also built the International Space Station, and continue making advances in all scientific areas.

Nothing, really. He is looked up to (rightfully so) for being the first human on the moon and inspiring a generation. But to call him a hero is to distort reality. Heroes save lives, sometimes putting their own lives in danger to do so. There are other things that you can do to become a hero (not going to go into that). But being inspirational and famous doesn't make you a hero, nor does setting a world record.

ACTUALLY,they can spend more than 6 months they can be on there for 803 days that is the record!

They literally used Silly Putty.

NASA candidacy requirements Be citizens of the United States. Pass a strict physical examination, and have a near and distant visual acuity correctable to 20/20 (6/6). Blood pressure, while sitting, must be no greater than 140 over 90. A bachelor's degree in engineering, biological science, physical science or mathematics is required, and a graduate degree is desired, although not essential.(this means you need a PHD, you thought college was hard to get into try this) At least 1,000 hours flying time as pilot-in-command in jet aircraft. Experience as a test pilot is desirable. Height must be 5 ft 4 in to 6 ft 4 in (1.63 to 1.93 m). Distant visual acuity must be correctable to 20/20 in each eye

The first shuttle missions had a crew of 2, many later missions had 5. Nowadays, the usual crew is 7 people (commander, pilot, several mission specialists, and rarely a flight engineer). One 2 occasions, 8 astronauts have flown (missions STS-61-A and STS-71). In case of an emergency rescue mission, the absolute maximum crew is 11.

They are absolutely vital for space-walks that is with Oxygen cylinders on the back-pack. some of the newer space ships have artifiically atmospheric cabins so they don't have to wear the clumsy helmets all the time, they are of course donned during the re-entry phase as there is the danger the capsule could lose its pressure envelope and on the hose ( Oxygen) better safe than sorry.

The primary reason is to reduce the payload weight the rocket must lift, every pound lifted into orbit costs about $10,000 to get it there. Water needed to rehydrate it before it is eaten is not taken into orbit, it is available free as the waste product of the fuel cells that generate electricity for the spacecraft. Also some water on modern spacecraft is recycled from urine by using reverse osmosis to purify it.

Astronauts experience 3g's which is no problem during takeoff, however during landing the astronauts experience 15 minutes of 3 g forces with weakened cardiovascular systems to to prolonged exposure to microgravity. Their suits however, prevent blackouts.

To date, the United States Naval Academy has produced the most (53), with the Air Force Academy in second with 34.

They weren't weightless. They weighed 1/6 as much as they weighed on Earth. They were carrying backpacks that weighed about 80 pounds on earth. They compensated for the extra weight on their backs by leaning forward to keep their center of gravity centered above their feet so they wouldn't fall over.

yes. over years astronauts have taken animals in space to test them. they also see how long they can live in outerspace. 2 Russian dogs have traveled in Sputnik 5. They successfully traveled around the world be themselves

They read the same way as they do on earth.

Only 3 countries have launched a rocket and sent astronauts in to space. The United States, China, and Russia. Many other countries have sent astronauts in to space but they went on rockets belonging to other countries.
