LIFE IN SPACE

LIFE IN SPACE

SUMMARY:

During their stay in space (ISS) astronauts have to continue living and working in an environment that is very different to that here on Earth. The conditions of weightlessness on the ISS hinder them perform vital functions but have to adapt to these conditions.

Astronauts have to conserve resources such as water needs and food.

In this series of video, ESA astronaut Frank De Winne and some of his fellow crew members, explain how the live on board the International Space Station.

Basics of hygiene:

1. Teeth: When you eat, some of the sugar in the food stays in your mouth. Bacteria feed on the sugar and make acid. This acid dissolves the tooth enamel and cause tooth decay. Everyone should brush your teeth to prevent this from happening and to keep them healthy and clean (even astronauts in space). Astronauts use toothpaste can swallow after brushing and mouth clean with a wet wipe. Astronauts have to brush their mouth so tight as possible to prevent mouth toothpaste out floating.
2. Waste: There is a special toilet on the ISS. The astronauts have to strap themselves in to prevent floating off. Instead of a flush toilet there is a suction tube which carries the waste away in an air stream down a hole. The solid gets compressed and stored for disposal later. The urine is connected and later recycled.
3. Dining in the ISS: The food is specially prepared. Some types of foods should be eaten to counteract the effects of adaptation to the space environment. Astronauts need to eat 2800 calories per day. The food trays are prepared on the ground for each astronaut and delivered to the ISS before he/she arrives. These are stored in one of the modules and marked. The food has to be specially treated so that it can last long time and is low in mass.
4. Exercising on the ISS: The astronauts have to anchor themselves firmly, or they would drift away - even using the computer becomes difficult. Space walks can be exhausting and put unusual strain on muscles. This means that astronauts have to take time to exercise and keep themselves fit and healthy to carry out their job on the ISS and to return to Earth in good shape.

PERSONAL OPINION:

In my opinion this article is the best I've found in the ESA.

I think is the most interesting and well explained. It tells about life in space, such as hygiene, sports, food ... and the description accompanies you with a demo video where you can see yourself as perform these basic functions.

The videos are very interesting and fun but  the fluency with spoken by astronaut above the level of content.

The article also includes pictures and very interesting science experiments to learn and so much fun.

Another thing that I liked a lot of this article has been not only limited to explain life in space, but it also introduces interesting information about the functioning of the human body, food ... Some of the curiosities you can will find in this article that I consider quite interesting are:

•          The damage we do the Coca Cola on teeth
•         Oxidation of perishables air.
•         The number and types of teeth we have and what they do.

In my opinion is a good article that could teach children from 1st and 2nd ESO for the content of `` science'' that show you, but I think the English  of this article, including the fluency with spoken by astronaut videos, descriptions and experiments is a complex English for children 13 to 14 years.

Therefore information / language relationship is not compensated.
