Astronauts

Astronauts face several challenges in zero gravity, including muscle atrophy, bone density loss, fluid shifts in the body, and changes in spatial orientation. These issues can affect bodily functions and create discomfort for astronauts during space missions. Adaptation to the microgravity environment is crucial for the long-term health of astronauts during their time in space.

Bread produces crumbs that can float in microgravity, creating a potential hazard to both equipment and astronauts. To avoid this, bread is typically avoided in favor of tortillas, which have a longer shelf life and don't produce crumbs.

Aside from doing the same things that are required to stay healthy on Earth, there is exercise that needs to be done, since the weightless environment places so much less strain on the body that the whole skeletal system tends to atrophy without extra exercise.

Michael Collins was the Apollo 11 Command Module pilot and stayed in orbit when Armstrong and Aldrin went down to explore the lunar surface on July 20, 1969. Each of the six Apollo landing missions (11, 12, 14, 15, 16, and 17) had one astronaut staying with the main craft and two astronauts taking the LEM (Lunar Excursion Module) to the surface and back.

Buzz Aldrin (born Edwin Eugene Aldrin, Jr.) was born on January 20, 1930.

There are many women named Eileen Collins. The Eileen Collins who is a retired American astronaut married pilot Pat Youngs in 1987.

The Apollo 13 mission had three astronauts: Jim Lovell, Fred Haise, and Jack Swigert.

No, Alan Armstrong, the son of Neil Armstrong, does not have any children. Neil Armstrong had three children from his first marriage to Janet Shearon.

A related occupation to an astronaut could be a pilot, as both roles involve operating and navigating complex machinery in extreme environments. Another related occupation could be an aerospace engineer, who designs and develops spacecraft and other aerospace technologies.

Astronauts primarily explore space within the confines of our solar system, such as the Moon, Mars, and the International Space Station. They have not traveled beyond our solar system to explore the entire universe due to the vast distances involved and current technological limitations.

Astronauts face challenges with eating in microgravity due to the lack of traditional methods such as using utensils and the concern of food particles floating away. Their food must be specially prepared to be easy to eat and prevent crumbs from floating around the spacecraft. Additionally, astronauts may experience changes in taste perception and appetite due to the effects of weightlessness on the body.

Touching helmets together can create a physical connection that may improve the transfer of sound vibrations between the two helmets, acting as a makeshift communication link. This can help the astronauts communicate in absence of a functioning communication system.

Judith Resnik was an American astronaut who was one of the crew members aboard the Space Shuttle Challenger during its tragic explosion in 1986. She was the second American woman in space and achieved a remarkable career in aerospace engineering before her untimely death. Resnik's pioneering spirit and contributions to the field of space exploration continue to inspire many.

There are currently about 240 astronauts across various space agencies worldwide, including NASA, ESA, Roscosmos, and others. The exact number can vary due to new selections, retirements, and international collaborations in space missions.

The pressure inside a space suit is maintained at around 4.3 psi (pounds per square inch) to provide a breathable atmosphere for astronauts in the vacuum of space. This pressure is necessary to prevent the astronaut's bodily fluids from boiling in the low pressure environment of space.

Judith Resnik, an astronaut who died in the Challenger space shuttle disaster in 1986, was not known to express specific fears publicly. She was a highly accomplished and fearless individual who excelled in her field of work.

If you mean from here on Earth, it is usually due to pollution or "light pollution" (excess light) which causes eye pupils and camera irises to adjust for brightness, thus keeping the dim starlight from being seen.

Astronauts in space can see stars, so long as there is no bright light to force their pupils to contract, thus letting in less light. Science fiction shows make people think that once you are in space, stars are bright enough to be seen through a window in a well-lit room. This simply is not true. The astronauts on the lunar surface didn't see stars as it was daylight and the Sun on the lunar surface was simply too bright for their eyes or cameras. In fact, their helmets had "sunglasses-like" darkening, as the Moon gets more sunlight than any desert on Earth.

Neil Armstrong's childhood home in Wapakoneta, Ohio burned down in 1992.

Chris Had field, who is a retired astronaut, lives in Canada. Beginning in the fall of 2014, he will begin teaching as a professor at University of Waterloo on a three year term.

In space, without gravity to pull the droplets towards the ground, your sneeze would disperse in all directions in a floating cloud of droplets. However, the cabin air filtration system onboard the spacecraft would eventually filter out the particles.

That would be Gemini 8. Neil Armstrong and David Scott docked with an unmanned Agena target vehicle on March 16th, 1966. The two spacecraft remained docked for approximately 31 minutes before a malfunctioning thruster on the Gemini spacecraft forced Armstrong to undock and terminate the mission after only 10 hours 37 minutes.

Being an astronaut is important because they conduct important scientific research in space, contribute to technological advancements for humanity, and serve as pioneers for future space exploration. Their work helps us understand the universe better and inspires the next generation of scientists and explorers.

As of my last update, Guion "Guy" Bluford Jr. lives in Ohio, United States. He was born in Philadelphia, Pennsylvania.

A total of 24 US astronauts have been to the Moon, and 12 have walked on its surface. There were a total of 27 astronauts on 9 Apollo lunar missions, but three of these went twice.

Astronauts eat food that has been specially prepared to avoid crumbs or liquids floating away. They can either eat it with a spoon or use utensils that have Velcro or magnets to stick to their trays. They can also drink liquids from specially designed pouches equipped with a straw.
