How long did it take to create the Hubble telescope?
First conceived in the 1940s and initially called the Large Space Telescope, the Hubble Space Telescope took decades of planning and research before it launched on April 24, 1990.
How long did it take to fix the Hubble telescope?
NASA finally fixed the Hubble Space Telescope after nearly five weeks without science operations. Hubble switched to backup hardware to correct the mysterious glitch that took it offline. Hubble’s age likely caused the problem. NASA hopes it still has a few more years.
How was Hubble telescope made?
Hubble uses two mirrors, laid out in a Cassegrain telescope design, to collect and focus light. After light travels down the length of the telescope, it hits the concave, or bowl-shaped, primary mirror. The light is then directed into science and guidance instruments for analysis.
Who built Hubble?
Lockheed Martin
NASA’s immense Hubble space telescope launched on April 24, 1990. Lockheed Martin built the complex spacecraft at its facility in Sunnyvale, California.
What is the farthest telescope from Earth?
The farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field.
Where was the Hubble telescope launched?
Kennedy Space Center, Florida
Space shuttle Discovery lifted off from Kennedy Space Center, Florida to launch and deploy the Hubble Space Telescope into low Earth orbit. Hubble was designed to be serviced by astronauts in order to maintain and repair the observatory and upgrade the science instruments to the most advanced technology available.
Why did astronauts service Hubble in 2009?
Between 1993 and 2009, astronauts visited Hubble five times to replace limited-life items such as batteries, gyroscopes and electronic boxes, and to install state-of-the-art science instruments. Each time astronauts visited Hubble, they left it a more capable, more productive observatory.
How much did it cost to build Hubble telescope?
It took two years before shuttle flights could resume and NASA could begin planning Hubble’s launch again. The world’s first space telescope finally launched aboard space shuttle Discovery on April 24, 1990. The effort cost $1.5 billion, but there would be ongoing costs — both expected and unexpected.
Where was Hubble telescope launched?
Kennedy Space Center
April 24, 1990 – Hubble launched. Space shuttle Discovery (on mission STS-31) launched from the Kennedy Space Center in Florida, carrying five astronauts and the Hubble Space Telescope.
