Astronauts

to become an astronaut you have to be 2 years old

As of November 2021, there have been around 580 astronauts from various countries who have flown to space. This number includes both active and retired astronauts who have completed missions to space.

Weightlessness is the effect that astronauts enjoy in space.

"An astronaut" is the correct form, not "a astronaut." "an" is used instead of "a" whenever the word it modifies begins with a vowel.

Astronauts do not sleep in traditional beds; instead, they sleep in sleeping bags that are secured to the walls of their spacecraft or space station. This prevents them from floating around in microgravity while they sleep. The sleeping bags help provide a sense of security and comfort, allowing astronauts to rest while minimizing the risk of drifting into equipment or other crew members.

The large rocks and soil samples that astronauts brought back from the Moon are commonly referred to as "lunar samples" or "moon rocks." These samples were collected during the Apollo missions and have been invaluable for scientific research, helping to enhance our understanding of the Moon's geology and history. Some of these samples are preserved in museums, while others are used for ongoing scientific study.

Being an astronaut can be a rewarding career for those passionate about space exploration, science, and technology. It offers unique opportunities for discovery, adventure, and contributing to advancements in human knowledge. However, it also comes with significant challenges, including rigorous training, long periods away from family, and physical and psychological demands. Ultimately, whether it’s a good career depends on individual interests and values.

Mae Jemison is known for her intelligence, determination, and pioneering spirit. As the first African American woman in space, she demonstrated exceptional academic prowess, earning a degree in chemical engineering and a doctorate in medicine. Her determination is evident in her journey to overcome barriers in a male-dominated field, while her pioneering spirit inspires future generations to pursue careers in science and technology.

The Gemini program flew orbital manuevering and docking exercises between 1964 and 1966, with crewed flights from 1965 to 1966. The Gemini spacecraft (missions III to XII) were flown by two astronauts each.

The U.S. space program that put astronauts in space is NASA's Mercury program, which launched the first American, Alan Shepard, into space in 1961. This was followed by the Gemini program, which enabled longer missions and two-man crews, paving the way for the Apollo program. Apollo famously landed astronauts on the Moon, starting with Apollo 11 in 1969. These programs collectively advanced human spaceflight and exploration.

Helen Patricia Sharman OBE (born May 30, 1963), is a chemist and former British astronaut. She was the first Briton in space, on Soyuz TM-12 which took off on May 18, 1991. Sharman was born in Sheffield; she is married with a daughter. She received a B.S. in chemistry at the University of Sheffield in 1984 and a Ph.D. from Birkbeck, University of London. She worked as an engineer for GEC in London and later as a chemist for Mars Incorporated working with flavorant properties of chocolate.[1] She was selected as astronaut on November 25, 1989, beating 13,000 applicants, after responding to a radio advertisement asking for applicants to be the first British astronaut.[1] The mission was known as Project Juno and was a cooperative arrangement between the Soviet Union and a group of British companies. Before flying, Helen spent 18 months of intensive flight training in Star City. The Juno consortium failed to raise the monies expected, and the partnership was almost cancelled. Reportedly Mikhail Gorbachev ordered it to proceed under Soviet expense in the interests of international relations, but in the absence of Western underwriting, substituted less expensive experiments. The Soyuz TM-12 mission, which included Soviet cosmonauts Anatoly Artsebarsky and Sergei Krikalev lasted 8 days, most of that time spent at the Mir space station. Her tasks included medical and agricultural tests, photographing the British Isles and participating in an amateur radio hookup with British schoolchildren. For her pioneering efforts, Sharman was appointed an OBE in 1993. She has not returned to space since this mission, although she was one of three British candidates in the 1992 European Space Agency astronaut selection, and on the shortlist of 25 applicants in 1998. Sharman now works as a broadcaster and lecturer specialising in science education. In 1991, she lit the flame at the 1991 Summer Universiade, held in Sheffield.

Since most space flights since 1962 last more than one day, space agencies have had to plan on how to deal with bowel movements while in space. The earliest options on some of the longer Gemini missions and during the two week long Apollo missions, astronauts basically would try their best to empty their bowels into a sealable plastic bag (a few steps up from a modern ZipLock). Additionally, used TP would added to that bag and sealed. Once sealed, there was an antibiotic ampule in the bag that the astronaut would break to kill any bacteria and keep the bag from inflating with gas. These bags were stored on-board the spacecraft (they did NOT dump their feces out in space, however the astronauts on the moon did dump their used feces bags overboard before returning to lunar orbit). Modern spacecraft, from Skylab to the Space Shuttle and ISS have a small toilet that uses air flow in lieu of gravity to keep solid wastes moving in the intended direction.

We see astronauts floating in space but not on earth.why?

No, only 12 people have visited the Moon, all of them between 1969 and 1972. Ms. Chawla was only born in 1962, and first flew on the space shuttle Columbia in 1997. She returned to space on Columbia in 2003 and died with her shipmates when it disintegrated on re-entry.

No, they did not.

Neil Armstrong was chosen as the mission commander for Apollo 11 due to his extensive experience as a test pilot and astronaut. He had previously flown on Gemini 8, where he demonstrated exceptional skills in handling complex situations. His calm demeanor and ability to make critical decisions under pressure made him an ideal leader for the historic lunar landing mission. Armstrong's leadership was crucial for the success of Apollo 11, as it was the first mission to land humans on the Moon.

The people who go to space are those who have trained for it such as astronauts.

Check navigation, collect data, complete maintenance, and conduct experiments are the kinds of work which astronauts do on space missions. For example, astronauts and cosmonauts may have to engage in checks on the effects of solar winds and weightlessness, repair or upgrade equipment, and verify their vehicle's direction and speed.
