After 31 years in space, the Hubble Space Telescope unexpectedly shut down on June 13 after suffering a problem that initially appeared to be the fault of an aging memory module . But the more NASA personnel tried to fix the issue, the more slippery it became.
What flaw did the Hubble telescope have?
It suffered from spherical aberration —not all portions of the mirror focused to the same point. The mirror's shape was off by less than 1/50th the thickness of a human hair, but this tiny flaw proved devastating to the quality of the Hubble's images and to the efficiency of all of its instruments.
What was wrong with the Hubble telescope and how did they fix it?
Each piece of Hubble's hardware has a twin pre-installed on the telescope in case it fails. So engineers just had to switch to that backup hardware. ... A year later, astronauts repaired two broken instruments while in orbit — that was Hubble's fifth and final servicing operation.
What was wrong with the Hubble telescope kids?
Telescopes in space can take better pictures than telescopes on Earth, but for some reason, the pictures were not better than the pictures taken on Earth. They found a problem with the telescope's mirror . The mirror was not curved right. It was only wrong by 2.2 microns (1/50th as thick as a piece of paper).
Is Hubble broken?
NASA anticipates that Hubble will last for many more years and will continue making groundbreaking observations, working in tandem with other space observatories including the James Webb Space Telescope to further our knowledge of the cosmos. Launched in 1990, Hubble has been observing the universe for over 31 years.
Why did Hubble need glasses?
Essentially, Hubble was Mr. Magoo. It couldn't see well and it needed some glasses . And so NASA was, of course, tremendously embarrassed by a mirror that wasn't shaped entirely properly and it had fuzzy vision.
Will Hubble be serviced again?
That being said, there are no plans for a new service mission . If there's a catastrophic failure that takes Hubble entirely offline, it's hard to see NASA greenlighting a repair mission for an observatory that's over three decades old.
Is Hubble back online?
By switching to backup power supply electronics as well as a backup payload computer, the US space agency was finally able to bring Hubble back online . ... Through their efforts, Hubble will continue its 32nd year of discovery, and we will continue to learn from the observatory's transformational vision.”

Can you see Hubble from Earth?
Hubble is best seen from areas of the Earth that are between the latitudes of 28.5 degrees north and 28.5 degrees south . This is because Hubble's orbit is inclined to the equator at 28.5 degrees. ... So northern parts of Australia have great access to seeing the HST and can catch the telescope flying right overhead.
How far can Hubble see?
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.
Are Hubble telescope pictures real?
TLDR: Yes, Hubble images are real . This series of posts is dedicated to the scrutiny of Hubble imagery and a broader discussion of the veracity of astronomical imagery.
Is Hubble telescope dead?
The telescope was last serviced in 2009 , following which it has taken more than 6,00,000 observations, bringing its lifetime total to more than 1.5 million. Nasa had earlier said that most of the observations missed while science operations were suspended will be rescheduled for a later date.
Why did NASA shut down Hubble telescope?
NASA is working quickly to fix the Hubble Space Telescope after an issue with a 1980s-era computer on board caused the famous orbiting observatory to temporarily shut down. ... The Hubble operations team suspects that the trouble could be due to a degrading memory module, according to a NASA statement.
Where is Hubble now?
Download “Observatory” information as a PDF
Launched on April 24, 1990, aboard the Space Shuttle Discovery, Hubble is currently located about 340 miles (547 km) above Earth's surface , where it completes 15 orbits per day — approximately one every 95 minutes.
What is the farthest star ever seen by Hubble?
Nasa's Hubble telescope captures image of Icarus , farthest star ever seen. Nasa's Hubble Space Telescope has discovered the farthest individual star ever seen – an enormous blue stellar body nicknamed Icarus located over halfway across the universe.
