Garbage blocking the way of the spacecraft

The US Aerospace Agency (NASA) decided to let Space Shuttle Discovery dodge the orbit of a piece of cosmic trash before it returned to Earth.

The control center said, the piece of trash had come near the International Space Station (ISS) on a space walk on Saturday last week. Experts do not know what that piece of trash is.

Discovery should have landed on September 10, but the presence of the storm caused it to stay in orbit for another day or two. According to the AP, the ship was on the ISS for more than a week. Timothy Kopra astronaut follows the train back to Earth after nearly two months living on the station.

Discovery has brought about 7 tons of cargo to ISS, including a bedroom, a cooling device, food, and exercise machines and will carry more than two tons of waste and leftovers to the earth.

According to Reuters, Discovery astronauts made three space walks to replace a bottle of liquid ammonia to store urine, blood and many other astronauts' things.

NASA hopes to complete ISS by the end of next year. The construction of this space station was started at the end of 1998 and the workload was 84%.
