Q. With reference to International Space Station (ISS), consider the following statements:
1.The ISS was taken into space piece-by-piece and gradually built-in orbit.
2.The ISS tends to sink from its orbit at a height of about 250 miles above the Earth.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C

Notes:

Both statements are correct.

The ISS is the most complex international scientific and engineering project in history and the largest structure humans have ever put into space.

This high-flying satellite is a laboratory for new technologies and an observation platform for astronomical, environmental and geological research.

The International Space Station was taken into space piece-by-piece and gradually built in orbit. It consists of modules and connecting nodes that contain living quarters and laboratories, as well as exterior trusses that provide structural support, and solar panels that provide power.

Due to its enormous weight and the ensuing drag, the ISS tends to sink from its orbit at a height of about 250 miles above the Earth. It has to be pushed up to its original line of motion every now and then.
