International space station | ISS

International space station:

The International space station is the largest and complex science and engineering project in the history of space science. The first component of ISS was launched in 1998  into the orbit, and now ISS is the largest human made model in low earth orbit.The satellite is like a home where astronauts live. The satellite is used as a laboratory for new technologies and a platform for astronomical and geological researches. It serves as a space environment research laboratory in space for biology, physics and meteorology researchers also. ISS is the largest space station, many countries work together to build it and also many space agencies work together.

Distance and Speed of ISS:

The International space station flies at an average altitude of 248 miles (400 km) above the earth. It completes its orbit in approximately 90 minutes at a speed of about 17,500 miles ph (28,000 kilometers-ph). It completes approximately 15 orbits in a day.

Structure:

The space station has many parts. The parts of the station are called modules. The space station was taken into space piece by piece and built by connecting nodes into the orbits by astronauts. It consists of models which include laboratories, living rooms and also the nodes to connect solar panels which provide power.

The first module of ISS “Zarya” was launched on 20 November 1998 by Russian Rocket. It provides attitude control, communication and electrical power. Two weeks later “Unity” was launched by NASA and connected to Zarya by astronauts.Over the time, many modules were connected to ISS by NASA and its partner over the world. The space station is finished in 2009.

The ISS  is a programme of five space agencies NASA, Roscomos, JAXA, ESA and CSA. Thw space station has two sections, the Russian Orbital section and United states Orbital section, shared by many nations.

How big is the space station?

The space station, including its solar arrays and body, is as large as the area of a football field. Inside, it is as big as a house with five bedrooms. It has two bathrooms, a gymnasium and laboratory.Six people can live in the space station. It consists of science labs from United states, Russia, Japan and Europe.

The weight of the space station is 861,804 lbs (391,000 kilograms), not including the visiting vehicle and rockets. As it has 5 bedrooms and 2 bathrooms, it also has a 360-degree bay window. The astronauts compare the living style in the space station with the cabin of a jumbo jet.

Why is space station important?

The space station is like home above the earth in an orbit. Since 2000, people have lived in space every day. The laboratories in the space station, where astronauts do their research which they could not do on the earth.
Space station used to study the life in the space and NASA learned about the life in space and how to control the space stations life because NASA is thinking to send their astronauts more deep in the space in future.
