The 7 largest objects people ever launched into space

The International Space Station, the Saturn V rocket, the Hubble space telescope are three of the largest human objects ever launched into space.

The International Space Station (ISS) is larger than a football field with a length of 108.5m and width of 73m, according to Popular Mechanics.ISS weighs 450 tons, moving in space at an average speed of 27,744km / hour, corresponding to 15.79 times of the Earth's daily flight.

Saturn V is a multistage space rocket used in the Apollo Program to bring people to the Moon and launch the Skylab space station of the US Aerospace Agency (NASA).The 111-meter rocket, capable of carrying 140 tons of mass on Earth's low orbit.NASA launched 13 Saturn V missiles from 1967 to 1973.

In 1986, the Soviet Union built the Peace Space Station, or Mir Space Station , to carry out scientific experiments in space, serving the purpose of peace and human development.This space station weighs 140 tons with a length of 33m, width of 30.8m, including a total of 6 modules.Mir ended operations on March 23, 2001, and was destroyed when he entered the Earth's atmosphere.

The Hubble Space Telescope is a joint project between NASA, the European Space Agency (ESA), the Space Telescope Science Institute, USA.Hubble is about the size of two adult African elephants combined with a volume of 12.2 tons.It started operating in 1990 at a height of 610 km from Earth.Hubble is a reflecting telescope equipped with a computer system and a light-collecting mirror with a diameter of 2.4 m.It can observe an object at a distance of 12 billion light-years because it is not affected by the Earth's atmosphere.

Skylab is the first US space station.On May 14, 1973, NASA successfully launched Skylab weighing 77 tons on Earth's orbit, opening a new turning point in the field of exploring the universe and bringing people into space.In 1979, this Space Station ceased operation, fell to the Indian Ocean and some debris fell in western Australia.

Envisat (Environmental Satellite) is ESA's largest Earth observation satellite.In 2002, it was launched from the Guiana Space Center with Ariane 5. This satellite weighs 8.2 tons, nearly 10 meters long.ESA lost contact with Envisat in 2012.

Self-propelled transport ship (ATV) is an ESA spacecraft.It is used to transport laboratory equipment, laboratory equipment, food, water, air and fuel for the International Space Station (ISS).ATV weighs nearly 21 tons and is large enough to accommodate a two-story bus.The outside of ATV is a cylindrical 10.3m long with a diameter of 4.5m.The main body of the ship is X-shaped solar panels.
