The mirror, made in the early 1980’s, has a symmetrical distortion known as spherical aberration, which throws off the Hubble’s focus so that starlight, instead of falling at one point within the telescope, is spread over an area. The current space shuttle mission is to repair that flaw.
NASA sent up astronauts in the space shuttle Endeavour to manually repair the telescope. Five space walks later, the astronauts completed the repairs. They installed a device containing 10 small mirrors that intercepted the light from the primary mirror and corrected the pathway to the sensors.
Also Know, what did the company that made the Hubble’s mirror not tell NASA? NASA has established how a mirror aboard its $1.5 billion Hubble Telescope came to be the wrong shape. The agency said last week that errors in a test instrument apparently led Perkin-Elmer, which fabricated the optics, to finish the 2.4-metre primary mirror of the Hubble Space Telescope incorrectly.
Beside this, what was the problem with the Hubble Space Telescope and how is it solved?
Hubble launched to Earth orbit in April 1990, aboard the space shuttle Discovery. But the telescope’s initial images weren’t as sharp as expected, a problem that astronomers traced to a slight defect in Hubble’s primary mirror. This problem was solved in December 1993, when astronauts installed corrective optics.
When was the Hubble Space Telescope fixed?
Dec. 2, 1993
Is Hubble visible from Earth?
Hubble’s low orbit means many targets are visible for slightly more than half of an orbit’s elapsed time, since they are blocked from view by the Earth for almost one-half of each orbit.
How far can Hubble see?
about 10-15 billion light-years
How long will Hubble last?
What will replace Hubble telescope?
The James Webb Space Telescope (JWST or “Webb”) is a space telescope that is planned to be the successor to the Hubble Space Telescope.
Where is Hubble telescope located?
Wilson Observatory near Pasadena, Calif., to discover galaxies beyond our own. Hubble, the observatory, is the first major optical telescope to be placed in space, the ultimate mountaintop.
How much did it cost to repair the Hubble telescope?
If detected prior to launch, the repair would have cost $2 million, an investigation into the cause of the flawed mirror found. But with Hubble orbiting 355 miles above Earth, NASA decided to fix it during the planned 1993 servicing mission.
What is the Hubble mirror made of?
Instead of a solid core, Hubble’s primary mirror has a honeycomb core, reducing its weight from 8,000 pounds (3,636 kg) to 1,800 pounds (818 kg). Both mirrors are coated with thin layers of aluminum and magnesium fluoride.
Who designed the Hubble telescope?
Who repaired the Hubble telescope?
Repairing the Hubble Space Telescope: The Tools Astronauts Used. NASA astronauts John Grunsfeld and Steven Smith upgrade the Hubble Space Telescope during the STS-103 servicing mission to the observatory in December 1999. Astronauts serviced the telescope during five space missions from 1993 through 2009.
How old is the universe?
13.772 billion years
How heavy is the Hubble telescope?
The telescope is 43.5 feet (13.2 meters) long, weighs 24,500 pounds (11,110 kilograms) and cost $2.5 billion. Hubble’s six cameras and sensors see visible, infrared and ultraviolet light. At the heart of Hubble is its 8-foot-diameter (2.4 meters) primary mirror.
How was the Hubble Deep Field image taken?
The image was assembled from 342 separate exposures taken with the Space Telescope’s Wide Field and Planetary Camera 2 over ten consecutive days between December 18 and 28, 1995. In 2004 a deeper image, known as the Hubble Ultra-Deep Field (HUDF), was constructed from a few months of light exposure.
How many newborn stars are in the Orion Nebula?
The Orion Nebula is an example of a stellar nursery where new stars are being born. Observations of the nebula have revealed approximately 700 stars in various stages of formation within the nebula.
What instruments does the Hubble telescope carry?
The Hubble Space Telescope has three types of instruments that analyze light from the universe: cameras, spectrographs and interferometers.
