According to Space.com, before leaving the ISS, astronaut Kevin Ford drove the ship flying around the station while other crew members photographed the space station. Astronauts on the ISS also watched the ship glide around their mid-air lab.

"The scene is so amazing when watching the roller coaster below. We all stick to the window, " said Michael Barratt on ISS.

Discovery has brought about 7 tons of cargo to ISS, including a bedroom, a cooling device, food, 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%.
