Long answers:
knowledge: content: The International Space Station (ISS) is a modular space station (habitable artificial satellite) in low Earth orbit
wikipage: International Space Station

content: The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields.
wikipage: International Space Station

content: Envisat ("Environmental Satellite") is a large inactive Earth-observing satellite which is still in orbit. Operated by the European Space Agency (ESA), it was the world's largest civilian Earth observation satellite
wikipage: Envisat

content: It was launched on 1 March 2002 
wikipage: Envisat

content: After losing contact with the satellite on 8 April 2012, ESA formally announced the end of Envisat's mission on 9 May 2012
wikipage: Envisat

content: The mission has been replaced by the Sentinel series of satellites. The first of these, Sentinel 1, has taken over the radar duties of Envisat since its launch in 2014.

long_answer: The International Space Station is a modular space station, also known as a habitable artificial satellite, that orbits the Earth. The International Space Station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics and other fields. Additionally, Envisat, or Environmental Satellite, is a large inactive Earth-observing satellite which is still orbiting the Earth. Operated by the European Space Agency, it was previously the world's largest civilian Earth observation satellite. It was launched on March 1, 2002. After losing contact with the satellite on April 8, 2012, the European Space Agency formally announced the end of Envisat's mission on May 9, 2012. This mission has been replaced by the Sentinel series of satellites. The first of these, Sentinel 1, has taken over the radar duties of Envisat since its launch in 2014. Another satellite that orbits the Earth, Aura is a multi-national NASA scientific research satellite. This satellite studies the Earth's ozone layer, air quality and climate. Aura is the third major component of the Earth Observing System, following Terra and Aqua, two satellites that also orbit the earth. The Earth Observing System, which contains the satellites Aura, Terra and Aqua, is a NASA program consisting of a series of artificial satellite missions and scientific instruments in Earth's orbit. These satellites and instruments are designed for long-term global observations of the land surface, biosphere, atmosphere and oceans.
