Astronauts can live in outerspace because in the space station they have water that is recycled, electricity provided by solar panels, and freeze dried food to last them the duration of their trip.

Astronauts eat specially prepared foods that are freeze-dried or vacuum-sealed to preserve them for long periods in space. They can rehydrate these foods using water dispensers on the spacecraft. Utensils like forks, knives and spoons are designed to prevent food from floating away in microgravity. Eating in space requires careful planning to ensure proper nutrition and waste management.

Astronauts eat specially designed food that can be rehydrated or prepared in a zero-gravity environment. They wear specially designed clothing with velcro and elastic straps to ensure it stays in place without gravity. For going to the toilet, they use vacuum toilets that suction waste away to prevent it from floating around in the spacecraft.

The astronauts spacesuits are a type of life support system to keep them alive when outside of the spacecraft. Then it supplies them with air, water, communications, cooling, waste disposal and anything else they need for survival in an environment in which it is impossible to live without it.

The orange spacesuits worn by space shuttle astronauts during launch and re-entry provide air,communications and also prevents their blood from pooling in one part of the body causing faintness.

Most of the time on the shuttle and the International Space Station, astronauts wear regular clothing and only need to use special suits for EVA and launch and re-entry procedures.

Astronauts need to do special exercises in space to prevent muscle and bone loss due to the lack of gravity. Without the effects of gravity on their bodies, muscles and bones can weaken and deteriorate over time. Special exercises help maintain their physical health during space missions and upon return to Earth.

An astronaut goes to space by training and being selected by a space agency such as NASA. They then travel to space onboard a spacecraft, such as the Russian Soyuz or the SpaceX Dragon, which launches from Earth to transport them to the International Space Station or other space destinations.

The synonym for "less space" would be "limited space" or "restricted space."

The smooth muscles inside the blood vessels adjust to the micro gravity in order to work properly, the same way they work on Earth. Also the heart rate slows since the muscles of the legs are not in use due to the lack of gravity

No, there are no "Radiation belts between the Earth and Moon. However. they do travel through the "Van Allen Belt". this is a "Belt" created by the earth's magnetic field that shields the earth from the some of the ratiation of the Sun and outerspace. Once an astronaut is outside of this "Belt" they are exposed to a higher level of radiation. The Van Allen Belt is highest at the earth's equator and lowest at the earths poles.

To become an astronaut, candidates typically need a bachelor's degree in a related field such as engineering, physical science, biological science, or mathematics. Advanced degrees are often preferred. Additional requirements include relevant work experience, physical fitness, and passing rigorous selection processes conducted by space agencies like NASA.

Mae C. Jemison - Physician and astronaut Born: 10/17/1956 Birthplace: Decatur, Ala. Astronaut Mae Jemison became the first African-American woman to enter space when she served on the crew of the Space Shuttle Endeavor in September 1992. Jemison's life, however, is also full of terrestrial accomplishments. A high school graduate at the age of 16, she attended Stanford University on a scholarship, graduating with a B.S. degree in chemical engineering and having fulfilled the requirements for an A.B. in African and Afro-American Studies. After graduating from medical school (Cornell University, 1981), Jemison joined the Peace Corps, serving as its area medical officer from 1983 to 1985 in the West African countries of Sierra Leone and Liberia. After serving in NASA from 1987 to 1993, Jemison founded The Jemison Group, Inc., which developed ALAFIYA, a satellite-based telecommunications systems intended to improve health care delivery in developing nations. She also was a professor in the Environmental Studies Program at Dartmouth College, where she directed the Jemison Institute for Advancing Technology in Developing Countries. Dr. Jemison, an avid Star Trek fan, had a role on an episode of "Star Trek : The Next Generation" in May, 1993.

The farthest distance a human has ever reached from Earth is to the Moon, which is approximately 238,900 miles (384,400 kilometers) away. This was achieved during the Apollo missions conducted by NASA in the late 1960s and early 1970s.

In 1976 - None, ditto 1977, 1978, 1979 and all the other years.

It's because they aren't getting enough exercise. When you walk, or run, or even just STANDING, it takes energy to pump the blood uphill to your heart. In space, in "zero-G", there isn't as much work, and it's all easier because you don't have to lift things against gravity.

Dafydd Williams retired from the Canadian Space Agency in 2011. He served as an astronaut from 1992 to 2011.

Cities located approximately on latitude 23.5°N include Mumbai (India), Cairo (Egypt), and Miami (United States). Cities on latitude 23.5°S include locations in Brazil, such as São Paulo and Belo Horizonte.

for a space suit you would need tubes that pumps hot and cold air

into the helmet and suit and pressurized atmosphere

Germany has sent the most people into space from Europe, including astronauts such as Alexander Gerst and Thomas Reiter. While Germany itself does not have its own human spaceflight program, German astronauts have flown on missions with NASA and the European Space Agency.

If take in the case of orbiters,there is a certain difficulty faced by all space agencies all over the world,they should launch their orbiters when the distance between earth and mars is short,if they fail to launch in that particular date,the agency have to wait for at least 2-3 years for a short and less fuel consuming journey.

Astronauts have not landed on Uranus and Neptune, as they have only visited the Moon, Mars, and the satellites of Jupiter and Saturn. Exploration of these distant gas giants would require advanced technology and significant challenges to overcome.

you will use the formula g=GM/(r^2)

where g = gravity, G is the universal constant, M is mass, and r is the radius of the planet.

earths mass is about 5.937e24 kg

and radius is about 6.371e6 km keep in mind that the earth is not perfectly spherical so this is a mean.

the universal constant is 6.67e-11

now plug in the numbers

g=GM/r^2

g = 6.67e-11 (5.937e24*2) / ((6.371e6)*2)^2

g = 6.67e-11 (1.1874e25) / (1.2742e7)^2

g = 6.67e-11 (1.1874e25) / (1.6235e14)

g = 7.91996e14 / 1.62359e14

g = 4.87805 m/s^2 or half that of earths.

now you can do it on your own.

keep in mind that this is not perfect if you were to calculate with accuracy you would need to know the composition of the planet (the density and thickness of the crust and such)

Because a space suit is used to provide the human body with earth-like conditions inside the suit. Earth already has earth-like conditions, therefore we do not need suits to be on the earth. On earth, we already have an atmosphere and the proper pressure and temperature to keep the atmospheric gasses dissolved in our blood and going to our tissues.

There are places on earth when we do need a 'suit' to stay alive. Places where the temperature, atmosphere and/or pressure are not adequate to keep us functioning properly require us to wear suits. Under water would be one place. There, we need a suit to keep us warm, and a mask to keep us breathing. Another place that I can think of is on top of a high mountain. Up there, the pressure is reduced enough that we have a difficult time getting enough oxygen to dissolve into our blood. So we increase our lungs' exposure to oxygen by wearing an oxygen mask.
