They also spend time in the crew quarters for rest and relaxation. Additionally, astronauts may engage in recreational activities, such as watching movies or exercising, to maintain their well-being during long missions in space.

As of October 2023, there have been over 600 astronauts from various countries who have traveled to space. This number includes individuals from space agencies like NASA, ESA, Roscosmos, CNSA, and others. The exact count can vary as new missions are launched and more astronauts are selected for training.

The first meal eaten in space by an American astronaut was consumed by John Glenn during the Mercury-Atlas 6 mission on February 20, 1962. He ate a meal that included a tray of applesauce, a tube of chicken and rice, and a few other items. The food was specially prepared for space travel, designed to be lightweight and easy to consume in a microgravity environment. This historic meal marked a significant milestone in human space exploration.

John Glenn spent a total of 9 days, 2 hours, and 58 minutes in space during his historic missions. His first flight was aboard Friendship 7 in 1962, where he became the first American to orbit the Earth. Later, he returned to space on the Space Shuttle Discovery in 1998, becoming the oldest person to fly in space at the age of 77.

Astronauts keep in contact with their families primarily through scheduled video calls and email exchanges facilitated by NASA's communication systems. They can send and receive emails from the International Space Station (ISS) using a system similar to the internet, albeit with some delays. Video calls are typically arranged during specific times, allowing astronauts to maintain a connection with loved ones despite the distance. Additionally, astronauts often record video messages or send audio updates that can be shared with their families.

Astronauts prepare for space travel through rigorous training that includes physical fitness, technical skills, and simulations of space conditions. They undergo extensive simulations in zero-gravity environments, practice emergency procedures, and learn to operate spacecraft systems. Additionally, they receive specialized education in areas like robotics and scientific research to effectively conduct experiments in space. Psychological training is also crucial, helping them cope with isolation and confinement during missions.

To become an astronaut, you should have a strong educational background, typically in fields like engineering, physical science, biological science, or mathematics.

Astronauts rely on various scientific disciplines, including physics for understanding forces and motion in microgravity, biology for studying human health and life support systems, and chemistry for managing materials and reactions in space. Additionally, Earth sciences help them monitor and understand environmental changes on our planet. Knowledge in engineering is also crucial for operating spacecraft and conducting repairs. Overall, a multidisciplinary approach is essential for the success of space missions.

Astronauts do not attach themselves to the rocket in space; instead, they are secured within the spacecraft or module that is part of the launch vehicle. During launch, they are strapped into their seats with harnesses designed to keep them safe under the forces of acceleration. In space, if they need to conduct spacewalks or move outside the spacecraft, they use tethers and safety lines to prevent drifting away. Communication and coordination with the spacecraft's systems ensure their safety while in orbit.

Astronauts do not do laundry in space like we do on Earth. Instead, they wear their clothing for several days and then dispose of them when they become too dirty or odorous, as washing clothes in microgravity is impractical. The used clothing is packed into trash bags and sent back to Earth in supply spacecraft, which burn up upon re-entry. This system helps manage waste while ensuring astronauts have clean clothing for their missions.

In a weightless environment, astronauts use rinseless wipes, no-rinse body wash, and moist towelettes to maintain personal hygiene. Instead of water, they apply special antibacterial wipes to clean their skin. For hair, they use a no-rinse shampoo that can be massaged into the scalp and wiped away without the need for water. This method helps them stay clean while conserving resources in the confined space of a spacecraft.

Space suits are designed to provide life support and protection in the harsh environment of space. They are equipped with layers that regulate temperature, provide oxygen, and remove carbon dioxide, while also shielding astronauts from radiation and micrometeoroids. The suit's materials are durable yet flexible, allowing for mobility, and include a helmet with a visor for visibility and protection against solar glare. Additionally, they feature communication systems and a cooling system to manage body heat during extravehicular activities.

A meteor, often referred to as a "shooting star," is a small particle from space that burns up upon entering Earth's atmosphere, creating a brief flash of light. In contrast, a comet is a larger celestial body made of ice, dust, and gas, which develops a glowing coma and tail when it approaches the Sun. While meteors are fleeting and last only seconds, comets are visible over days or weeks as they travel through the sky. Additionally, comets have a distinct, elongated shape and can be observed with telescopes, whereas meteors are typically seen with the naked eye.

The distance from the Earth to the Moon is approximately 384,400 kilometers one way. If astronauts travel to the Moon and back, the total distance is about 768,800 kilometers. If this journey takes 144 hours, the average speed can be calculated by dividing the total distance by the total time: 768,800 km / 144 hours ≈ 5,347 km/h. Therefore, astronauts would be traveling at an average speed of about 5,347 kilometers per hour.

To find your east and west horizons, you can use a compass, which indicates magnetic north; east will be to the right of north, while west will be to the left. Alternatively, you can observe the position of the sun: it rises in the east and sets in the west. If it's morning, face the sun, and your left will be north (west on your right). In the evening, the opposite applies as the sun sets.

Since Neil Armstrong's historic moon landing in 1969, humanity has made significant advancements in space exploration.
