It was just a few years after the Hubble Space Telescope’s launch in 1990 that its operators found that the observatory’s primary mirror had an aberration that was impairing the sharpness of the telescope’s initial photographs. The end product was a mirror with an aberration one-fiftyth the thickness of a human hair, which was created during the grinding process.
What are some interesting facts regarding the Hubble Space Telescope?
- Getting Hubble off the ground was a major accomplishment. The first time Galileo looked up at the skies with a spyglass in 1610, he had difficulty distinguishing the rings of Saturn that are now visible in low-cost

How did they fix the Hubble telescope’s mirror?
NASA engineers worked around the clock to come up with possible solutions, which included everything from inserting a spacewalking astronaut into Hubble’s optical tube to replace the telescope’s secondary mirror to installing a circular shade around the opening of the tube, reducing the aperture, and improving the telescope’s overall performance.
Who screwed up the Hubble mirror?
A list of the “Top Ten Hubble Excuses” was prepared by David Letterman, who used the list to mock the space telescope. In addition, the New York Times reported in July that Perkin-Elmer was the lowest bidder for the construction of Hubble’s critically vital mirror, with a cost of $64.2 million.
What was wrong with Hubble and how did they fix it?
After nearly five weeks of science activities being suspended, NASA was able to repair the Hubble Space Telescope. Hubble was forced to switch to backup hardware in order to rectify the inexplicable fault that had brought it down. The issue was most likely caused by Hubble’s advanced age.
What problems did the Hubble telescope face?
The primary mirror of the Hubble Space Telescope is being polished before to installation. Because the edges of the telescope were polished just a little too flat, the telescope was unable to focus precisely.
How many Eva’s did it take to fix the Hubble?
Assisted by hundreds of engineers, technicians, and mission controllers on the ground, the Shuttle crew completed five back-to-back EVAs throughout the mission’s 11-day duration, spending a total of 35 hours and 28 minutes outside the ship during the trip.
Is the Hubble telescope broken?
NASA’s Hubble Space Telescope, which is one of the most important tools for space exploration, has been down for a second time. Since its inception in April 1990, the Hubble Space Telescope has proven to be an essential resource for scientists and astronomers all around the world.
How much did it cost to fix the Hubble telescope?
The repair operation had a total cost of $700 million in materials and labor. Astronomers would subsequently conclude that the money had been well spent because the photos returned by the restored Hubble far beyond those obtained by any other Earth-bound telescopes at the time.
How heavy is the Hubble telescope?
Hubble weighed around 24,000 pounds when it was launched, but if it were to be returned to Earth today, it would weigh approximately 27,000 pounds, which is equivalent to the weight of two full-grown African elephants. The primary mirror of Hubble’s spacecraft is 2.4 meters (7 feet, 10.5 inches) in diameter.
What was the major problem with the Hubble Space Telescope when it was first launched into orbit group of answer choices?
Hubble Space Telescope discoveries | a timeline 1990 | After nearly two decades of planning, the Hubble Space Telescope is launched into orbit around the Earth. During the initial flight of Hubble Space Telescope in 1993, a problem with the mirror generated a significant blurring effect, which seriously impeded the space telescope’s capacity to accomplish ground-breaking astronomy.
Why is the Hubble telescope being replaced?
Webb is frequently referred to as Hubble’s replacement, but we prefer to refer to it as Hubble’s successor. After all, Webb is the scientific successor to Hubble, and the research aims of the mission were inspired by Hubble’s discoveries. The science of Hubble has encouraged us to study at longer wavelengths in order to “go beyond” what Hubble has already accomplished.
Does the Hubble telescope use mirrors?
To gather and concentrate light, Hubble employs two mirrors that are set out in a Cassegrain telescope configuration. As light makes its way down the length of the telescope, it comes into contact with the primary mirror, which is concave or bowl-shaped.
