Astronauts

The Soviet Union sent the first man, Yuri Gagarin, into space on April 12, 1961.

Kalpana Chawla was on board to the spacecraft Columbia in 2003 and while it was time to re-entry, the space shuttle was pulled apart because there was a hole inwing caused by falling foam at the time of lift-off allowed the extreme heat of the re-entry process to enter the wing structure and cause landing problem.

If an astronaut falls ill in space, they would typically be treated using the medical equipment available onboard the spacecraft. The astronaut would also be in regular communication with medical staff on Earth who can provide guidance for treatment. In serious cases, the astronaut may need to be evacuated back to Earth for more advanced medical care.

Astronauts may experience disrupted sleep patterns in space due to factors like increased exposure to light, noise, and changes in gravity affecting their circadian rhythms. Some astronauts report needing less sleep because they are more physically active, have higher levels of stress, or simply due to the excitement and novelty of being in space. However, adequate rest is crucial for their health and performance, so astronauts are encouraged to prioritize sleep hygiene and use tools like sleep masks and earplugs to help regulate their sleep.

Transpiration can help regulate humidity levels within the spacecraft, maintaining a comfortable environment for astronauts. It can also help purify the air by removing toxins and imparting a sense of natural air circulation. Additionally, transpiration can contribute to a psychological boost by providing astronauts with a connection to nature.

Traveling to the other side of the galaxy is currently not feasible with our current technology. The distance is so vast that it would take tens of thousands of years even at the speed of light, making it impractical for humans to undertake such a journey.

Robert Thirsk is a Canadian astronaut who participated in two space missions. During these missions, he conducted various scientific experiments, performed maintenance tasks on the International Space Station, and contributed to ongoing research in space medicine and human physiology. Thirsk also helped to promote international cooperation in space exploration.

Astronauts living in microgravity face challenges like muscle and bone loss, fluid redistribution leading to a puffy face and skinny legs, cardiovascular deconditioning, and decreased immune function. They also experience difficulties with spatial orientation, as well as issues with sleep and nutrition.

Astronauts carry tools for conducting experiments, communication devices, personal hygiene items, food and drinks, and specialized equipment for spacewalks. They also have cameras, laptops, and other equipment needed for their mission.

Being an astronaut offers the thrill of exploration, experiencing weightlessness, witnessing stunning views of Earth from space, and being able to conduct groundbreaking scientific research in microgravity. It also allows for personal growth, working alongside a diverse and talented team, and contributing to humanity's understanding of the universe.

Depends on which program you're referring to.

Mercury astronauts landed in the Atlantic Ocean.

Gemini astronauts also landed in the Atlantic ocean with the exception of Gemini 8 which, due to being aborted after less than a day in space, landed in the Western Pacific Ocean.

All Apollo crews landed in the Pacific Ocean with the exception of Apollo 7 & Apollo 9 which landed in the Atlantic near Bermuda and the Bahamas, respectively.

Russian Cosmonauts didn't land in the ocean at all--they came down on land.

Yes, 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.

People cannot breathe in space because there is no atmosphere to provide the necessary oxygen to sustain life. Astronauts wear specially designed spacesuits that have their own oxygen supply, allowing them to breathe while outside a spacecraft. Inside the spacecraft, there is a controlled environment with supply of oxygen for the crew to breathe.

An astronaut shelter is a structure or designated area where astronauts can seek refuge in the event of emergencies such as radiation exposure, fire, or rapid decompression. These shelters are typically equipped with supplies and resources to sustain astronauts until help arrives or until they can safely return to their spacecraft.

Six Apollo missions landed astronauts on the moon between 1969 and 1972. A total of 12 astronauts have walked on the moon during these missions. Since then, no human has returned to the moon.

Currently our technology is not well enough developed to send someone to another planet and return them safely. A lot of work still needs to be done before this can happen. It would be very expensive to go to other planets. It would also take a long time to get there and to get back. So there are many problems to be dealt with before it will be possible to do it.

Unmanned space probes have been sent to various destinations in our solar system, including Mars, Venus, Mercury, Jupiter, Saturn, Uranus, Neptune, and Pluto. They have also traveled beyond our solar system to study interstellar space.

Swallowing is a manipulation of the throat muscles, it's not down to gravity. In theory you can swallow while upside down (but it feels odd and is harder as you're working against gravity).

Hope this answers your question.

Yes, space ships have toilets that are specially designed to work in zero gravity. These toilets use suction systems to collect waste and are built with straps and footrests to help astronauts position themselves correctly. Waste is collected and stored until it can be disposed of appropriately after returning to Earth.

Depends on which country you're referring to. In Russia it would probably be Valentina Tereshkova; in the US--Sally Ride.

I've seen on tv, about this, they said they ate freeze-dried foods e.g. packets of sealed in aluminum freeze-dried bananas, and freeze-dried strawberries. I would venture a guess here and say they also eat sultanas and things like that. And, they also use tubes of things, and when the tube is opened, they put the tube to their mouths and suck on the tube to eat, and it's probably I think coffee and sweetened condensed milk together, since they cannot drink coffee in free-fall. It looks like also, they have bags of fresh water with a tube on it, they open the top of the tube, put the tube to their mouths, and sqeeze the plastic bag to have a drink of water. Who knows, they might have secret bags of coffee in those bags to squeeze; but, it would be cold coffee.

PS I saw on tv, either someone was joking OR it was true, some people started to eat the freeze-dried strawberries for the first time, just to see what it tasted like to an Astronaut, and these people were quoted as saying: "it tastes AWFUL, I never want to taste freeze-dried fruit ever again" and other comments.

The second astronaut, and first American in Space, was Alan B. Shepard, Jr. His flight was May 5, 1961.

The first seven American astronauts were the Mercury program astronauts: John Glenn Jr.; Virgil "Gus" Grissom; Donald "Deke" Slayton; Alan Shepard, Jr.; M. Scott Carpenter; Wally Schirra; L. Gordon Cooper, Jr.

Astronauts use a variety of specialized equipment in space, such as spacesuits for extravehicular activities, helmets for protection, communication systems for staying in touch with mission control, and tools to carry out experiments or repairs on the spacecraft. They also have access to exercise equipment to maintain their physical health and well-being while in microgravity.
