Today I am going to talk about the international space station also called as the ISS.

My first question is what is the ISS?

The ISS is a large spacecraft that orbits the earth. It serves as a home where crews of astronauts live.
The ISS is also a unique science laboratory. Several nationals worked together to build and use the ISS.
The ISS is made out of parts that were build in space by astronauts. NASA is using the ISS to learn more about living and working in space. The first piece of the ISS was launched in November 1998.
My second question is how does the ISS mimic conditions on earth?

The ways the ISS mimics conditions on earth is that they have to eat, drink and sleep.

They also have routinely clean the ISS also they must keep in good physical and hygienic condition by using wet wipes and exercising.

My third question is what technology's create conditions to earths on the ISS?
Because of zero gravity on the ISS it can carry out experiments that cannot be done on earth.

They check out the effects that zero gravity has on plants and animals or they can mix fluids which react different in space.

Scientists on earth can watch the experiments or carry out new ones. Even students around the world can take part in certain ISS experiments and compare results.

My fourth question is what do you do on the ISS?

Astronauts on the space station stay busy because their is lots of work to do and they have to operate the many science experiments on board.

The crew also has to make sure that the station is in top shape, they clean, check equipment, maintain and repair equipment, replace broken equipment.
Crew members also must exercise two hours each day to stay fit and keep their bones and muscles strong.
My fifth question is how fast does the ISS go?
The ISS travels through space 17,500 miles per hour at a attitude of about 220 miles. It orbits the earth every 90 minutes.

Astronauts are in constant training for space flight. The basic training involves learning about basic space station systems, space walking and operating the robotic arm.

You continue this training while awaiting a mission assignment. Training for your mission may take as long as three years. ISS missions require you to speak Russian which adds time to your training.

My last but not least question is what do you do for fun on the ISS?

The space station crews can ask mission control to send them shows that they can watch during dinner or off duty. They can also watch movies on their laptop.

They may bring books, music, musical instruments with them. Some astronauts enjoy hobbies such as, drawing, and photography.

During missions astronauts are really busy. The few hours of free time may be spent looking out the window at the beautiful earth below.
