Hubble has been serviced five times . Here are the highlights of each servicing mission: Servicing Mission 1 – STS-61, December 1993: A corrective optics package was installed, and the Wide Field Planetary Camera was replaced with the Wide Field and Planetary Camera 2 (including an internal optical correction system.)
How many times was Hubble serviced?
Astronauts first visited Hubble in orbit in December 1993. Including that trip, there have been five astronaut servicing missions to Hubble.
How do they repair the Hubble telescope?
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.
When was the last time that NASA repaired the Hubble?
Date: May 11-24, 2009 . The Hubble Space Telescope was reborn with Servicing Mission 4 (SM4), the fifth and final servicing of the orbiting observatory.
Can 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.
Why will Hubble never be visited again?
The Hubble Space Telescope circles Earth at an altitude of 353 miles (568 kilometers), but its orbit decays over time due to atmospheric drag . This means that a decision looms for NASA, regardless of how long the telescope continues to be healthy and scientifically productive.
How long will Hubble last?
| SATCAT no. 20580 | Website nasa.gov/hubble hubblesite.org spacetelescope.org | Mission duration 31 years, 4 months, 26 days (elapsed) | Spacecraft properties |

Is Hubble visible 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. ... In contrast, the ISS passes over much more of the Earth because its orbit has a higher inclination at 51.6 degrees.
Who owns NASA?

What is the farthest star ever seen by Hubble?
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. The star, harboured in a very distant spiral galaxy, is so far away that its light has taken nine billion years to reach Earth.
What is the future of Hubble?
What Is the Future of Hubble? Hubble turned 30 years old in 2020. Engineers designed Hubble so that it could be repaired and upgraded as needed . Since the telescope's launch, five space shuttle missions have carried astronauts to Hubble to repair and upgrade it.
What is replacing Hubble?
Webb Telescope is Hubble's successor. NASA said on September 8 that it now has a new official launch date for the James Webb Space Telescope: December 18, 2021. The agency set the new target launch date after the Webb successfully completed a rigorous testing regimen.
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.
What will happen to Hubble once we quit using it?
In 2016, NASA announced a five-year extension of science operations with the Hubble Space Telescope (HST). This means that, unless the telescope suffers a catastrophic failure that renders all its instruments unusable , HST will continue operating at least through June 30, 2021.
Who owns the Hubble telescope?
The Hubble is a joint project between NASA and the European Space Agency . Here are some basic facts about the telescope and the mission, courtesy of the Space Telescope Science Institute (STScI), which operates Hubble for NASA: Telescope size: Length: 43.5 feet (13.2 meters)
Can you see the flag on the moon through a telescope?
Can you see an American flag on the moon with a telescope? Even the powerful Hubble Space Telescope isn't strong enough to capture pictures of the flags on the moon. But the Lunar Reconnaissance Orbiter, the unmanned spacecraft launched in 2009, is equipped with cameras to photograph the moon's surface .
