Many people ask the same question, i don't really know for sure but around 1987 or 2000.
The Hubble Telescope was sent into space in 1990. It was designed and built for several years before that. As of 2014, it is still in operation.
The telescope sent into space to capture sharper and clearer images of planets, stars, and deep space is called the Hubble Space Telescope.
There is only one single Hubble Space Telescope. It was placed into Earth orbit in April of 1990, and is expected to remain useful and productive until sometime between 2014 and 2020.
NASA sent the Hubble to low earth orbit (320 miles), the crew that sent it there was Commander Loren J. Shriver, Pilot Charles F. Bolden, Jr., Mission SpecialistsSteven A. Hawley, Bruce McCandless II and Kathryn D. Sullivan on the STS-31 mission.
Yes there are there are many different ones, but here's just a few Herschell, planck, and Kelpler. They were recently sent and have a specific mission.
NASA's most famous telescope is probably the Hubble Telescope that orbits the earth.
The HST (Hubble Space Telescope) was sent aloft only once, on board the Space Shuttle Discovery. It was launched April 25, 1990, from the Kennedy Space Center at Cape Canaveral. http://archive.eso.org/~amicol/HST/launch_orbit_new.html Subsequent servicing missions were performed by other shuttle launches.
They have sent 6 space prbes to Jupiter.
the 2 most famous would be sputnik and hubble telescope, then you have telecomunications satellites, tv etc etc
Some of the spacecrafts that NASA has sent into space include the Voyager probes, the Mars rovers (such as Curiosity and Perseverance), the Hubble Space Telescope, the Cassini spacecraft that studied Saturn, and the New Horizons probe that explored Pluto.
One space probe has been sent to Pluto: NASA's New Horizons spacecraft. It performed a flyby of Pluto in July 2015, providing the first close-up images and scientific data of the dwarf planet and its moons.
The Hubble Space Telescope (HST) was launched into space to allow it to view the heavens without the distortion of images caused by looking through the atmosphere itself, the degradation of images caused by the dust in the atmosphere, and the interference caused by ambient light on the surface of the earth. All those problems can be partially overcome by a careful selection of a location for a telescope on earth, but putting the telescope in space completely eliminates all of them, except space dust.The improvement of the image quality allowed astronomers to look at small objects relatively close to Hubble, or huge objects much farther away.For example Hubble was used to study the dwarf planets in our solar system Pluto and Eris.Hubble was also used to study galaxies BILLIONS of light years away. A light year is a measure of distance. It is the distance light travels in one year. Light travels 5,860,000,000,000 miles in one year, so Hubble can see galaxy sized objects billions of times a light year away.The distance, however, is not the important part of that statement. The important part of the statement "billions of light years away" is "billions of years". Because Hubble can see so far it is, in fact, showing something NOW that happened billions of years ago. That is because the light had to travel for billions of years to reach Hubble. It is allowing astronomers and scientists to observe the universe as it was billions of years ago. This is producing a multitude of theories and scientific papers.that pretty much covered everything i said except that hubble was last luanched to get to the begginning of time, it's a big gamble for sientists...i don't even have to write more now :P
