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.
When was Hubble serviced?
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. During SM4, two new scientific instruments were installed – the Cosmic Origins Spectrograph (COS) and Wide Field Camera 3 (WFC3).
How many times has Hubble been serviced?
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.)
Can Hubble be serviced again?
The final Hubble servicing mission was launched in May 2009 and, absent the space shuttle, we
are told Hubble cannot be repaired again
. Without another servicing mission, Hubble will inevitably fail, most likely early in the next decade.
When was Hubble’s first servicing mission?
Aiming at correcting the optics of its flawed mirror shape and installing new instruments as part of a maintenance plan, the first Servicing Mission (STS-61) to the Hubble Space Telescope was launched in
December 1993
. Among the seven-member crew was European astronaut Claude Nicollier.
What was wrong with Hubble?
NASA has identified the possible cause of the
payload computer problem
that suspended Hubble Space Telescope science operations on June 13. … When the payload computer halted, Hubble’s science instruments were automatically placed into a safe configuration.
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.
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.
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.
How long was Hubble supposed to last?

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.”
Who owns NASA?

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.
How far in miles above Earth is Hubble?
The Hubble Space Telescope is a large telescope in space. It was launched into orbit by space shuttle Discovery on April 24, 1990. Hubble orbits about 547 kilometers
(340 miles)
above Earth. It is the length of a large school bus and weighs as much as two adult elephants.
Which shuttle flew the most flights?
Discovery
was the third shuttle to head into space, but it ended up flying the most missions: 39. Discovery also was the shuttle that did both “return to flight” missions after the Challenger and Columbia disasters.
Who said the universe is expanding?
In 1929,
Edwin Hubble
, an astronomer at Caltech, made a critical discovery that soon led to scientific answers for these questions: he discovered that the universe is expanding.
