It captures images of space, and then sends them back down to earth via satellite.
Hubble
The Hubble Space Telescope orbits the Earth about 350 miles up.
NASA's most famous telescope is probably the Hubble Telescope that orbits the earth.
The Hubble can see further into space because it orbits outside of earth's atmosphere.
The Hubble Space Telescope is a space-based observatory launched by NASA in 1990. It orbits Earth and captures high-resolution images of celestial objects in visible, ultraviolet, and infrared light. Hubble has greatly contributed to our understanding of the universe and made countless scientific discoveries.
The HST orbits at 569 km or 353 miles above Earth.
The Hubble space telescope orbits the Earth at a speed of approximately 4.7 miles per second, or 282 miles per hour.
The Hubble Space Telescope (technically it is not a 'spacecraft') orbits at 559 km (347 miles) above the Earth, at a speed of 7,500 m/s (17,000 mph).
The Hubble Space Telescope orbits Earth at an altitude of about 547 kilometers (340 miles). It does not travel through space like a spacecraft on a journey to another celestial body, but continuously orbits Earth in order to observe the universe.
Hubble's orbit is 366 miles (589 kilometers) above Earth
The ISS orbits at 400 km above Earth; the HST at 569 km.
It orbits at 17,500 miles per hour (almost 5 miles per second).
