ISS - International Space Station - Inside ISS - Tour - Q&A - HD

Summary

Astronaut Sunny Williams provides an insightful tour of the International Space Station, detailing living quarters, sleeping arrangements, and daily routines. She showcases the space bathroom, exercise equipment, and various laboratories, emphasizing the multicultural food and the importance of staying fit in zero gravity. Williams also discusses the thrill of spacewalks, the Soyuz capsule used for transportation, and the view of Earth from the Cupola, highlighting the unique experiences and challenges of life in space.

Takeaways

• 🚀 The International Space Station (ISS) is composed of various modules, each serving different functions such as sleeping quarters, laboratories, and storage.
• 🛌 Astronauts sleep in sleeping bags attached to the wall of the ISS, with no sensation of lying down due to the microgravity environment.
• 💻 Each Sleep Station doubles as a personal office, equipped with a computer, personal items, and a sleeping bag to prevent floating around.
• 🧼 In space, daily hygiene tasks like brushing teeth are performed differently; for instance, water sticks to toothbrushes due to surface tension.
• 🚽 The ISS has specialized bathrooms, or 'orbital ouses', with separate facilities for solid and liquid waste, and privacy is maintained with doors.
• 🍽 The ISS kitchen contains a variety of food from different countries, stored in dehydrated form or ready-made, and heated as needed.
• 🏋️‍♂️ Astronauts exercise regularly using equipment like bikes, treadmills, and weightlifting machines to counteract muscle and bone density loss in space.
• 👩‍🚒 The ISS is equipped with an airlock for spacewalks, where astronauts perform repairs and maintenance outside the station.
• 👨‍🚀 Astronauts come from diverse professional backgrounds, including doctors, teachers, and engineers, and those who enjoy exploration and adventure are often drawn to the role.
• 🌍 The ISS has observation modules, like the Cupola, where astronauts can look back at Earth, providing a unique perspective and a sense of connection to the planet.

Q & A

How many people sleep in Node 2 on the International Space Station?

Four out of six astronauts sleep in Node 2 on the International Space Station.

What is the sensation of sleeping in space compared to lying down on Earth?

In space, astronauts do not have the sensation of lying down as they just sit in a sleeping bag, and the orientation does not matter due to the lack of gravity.

What is the purpose of the Sleep Station on the ISS?

The Sleep Station serves as both a sleeping area and a personal office for astronauts, equipped with a computer, personal items, and a sleeping bag.

How do astronauts brush their teeth in space?

Astronauts use a toothbrush and toothpaste in space, where water sticks to the toothbrush due to surface tension. They can either swallow the toothpaste or spit it out into a paper towel.

What are the two main functions of the bathroom on the ISS?

The bathroom on the ISS has two main functions: handling solid waste and liquid waste, each with its own separate facility.

How do astronauts manage toilet paper in space?

Astronauts use gloves and have a selection of wipes including Russian wipes, tissues, and Huggies for cleanup. There is also disinfectant wipes for cleaning the area.

What types of food do astronauts have on the ISS?

Astronauts have a variety of food from different countries including the US, Japan, and Russia. The food is a mix of dehydrated items that need rehydration and pre-made items that require heating.

Why is exercise important for astronauts on the ISS?

Exercise is crucial for astronauts to counteract the loss of bone density and muscle mass caused by the absence of gravity in space.

What are the main components of a space suit and why are they needed?

A space suit includes a backpack that provides oxygen, carbon dioxide removal, heating and cooling, and a computer to monitor the suit's systems. It is large and bulky to protect the astronaut in the harsh conditions of space.

What is the role of the PMM (Pressurized Mating Adapter) on the ISS?

The PMM serves as a storage area for extra food, clothes, and trash. It is also used to organize items needed while working in various modules of the ISS.

How does the Soyuz spacecraft connect to the ISS?

The Soyuz spacecraft connects to the ISS using a docking probe that sticks into a cone on the ISS. This is then secured with clamps, allowing the two spacecraft to be attached.
