NASA fixed the Hubble Telescope by having astronauts install new instruments which included equipment that was adjusted to correct for the flaw in Hubble's primary mirror.

This installation of the instruments has extended Hubble's wavelength range into the near infrared for spectroscopy and imaging which allows scientists to probe the most distant reaches of our universe.

After 2040 Hubble is expected to begin falling back to earth as it should lose enough altitude to fall back to earth.

NASA has plans to give the Hubble telescope a propulsion system that should send it into the Pacific Ocean or send it higher up where it may remain for hundreds of years.

Hubble will be replaced and has been replaced with the James Webb Telescope that become operational around the end of June 2022.

Hubble is located around 340 miles above earth.

The Hubble Telescope orbits at just above the Earth's atmosphere at an altitude of around 340 miles and Hubble orbits at a speed of 17,000 miles per hour and completes 1 orbit approximately every 95 minutes.

You can see Hubble from Earth if you're in the right location as Hubble is best seen from areas of the Earth that are between the latitudes of 28.5 degrees north and 28.5 degrees south.

The Goddard Space Flight Center controls the Hubble Telescope.

The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft.

The Hubble Telescope is expected to last until 2030 or 2040.

The Hubble Telescope shut down after 31 years on June 13 2021 due to a bad aging memory module.

Hubble has four 64 bit memory modules and 3 of the 4 64 bit memory modules are backups.

Hubble's most recent image which was taken on Aug 19th 2022 was of a Star Studded Cluster.

The scintillating image showcases the globular cluster NGC 6540 in the constellation Sagittarius.

Hubble is better than ground telescopes as the images that Hubble can take are between 5 to 20 times sharper and clearer than images obtained from the ground telescope.

The image sharpness and the dark sky allows the Hubble Telescope to see things 10 times fainter than those that can be seen with a ground telescope.

The James Webb Telescope is better than Hubble as it's six times bigger and also 100 times more powerful and can see much farther than the Hubble.

The James Webb Telescope is gold as gold was applied to the surface of the mirrors to improve the reflection of infrared light.

The James Webb telescope is 100 times more powerful than Hubble.

James Webb telescope is also six times bigger than Hubble and can see much farther..

The James Webb telescope can see as far as 13.6 billion light years away.

You can see a glimpse of the James Webb Telescope from earth or if you use a telescope you can see it pretty clearly.

James Webb telescope can see as far as 13.6 billion light years away.

The thing that is so special about the James Webb Telescope is that it can see much deeper into the Universe unlike the Hubble Telescope which means it opens up a new era of cosmology.

James Webb Telescope's sensitivity to much longer wavelengths allows it to peer through dust clouds that would normally obscure stars, planetary systems, and distant galaxies from Hubble's prying eye.

This means the James Webb Telescope is so sensitive it can actually reveal the composition of far-away exoplanets' atmosphere.

James Webb telescope is successful and has launched with success and opened up without any problems.

As of now the James Webb telescope is in operation and is the current successor telescope to the Hubble Telescope.

The next telescope after Hubble Telescope is the new Webb Telescope which is the current successor telescope to the Hubble Telescope.

The newest space telescope is the James Webb Telescope also known as the Webb Telescope.

The Webb Telescope is the current successor to the Hubble Telescope which has been in space for 30 years.

The James Webb telescope is working and was successfully launched.

The James Webb telescope was built by the European Space Agency at ESTEC in Noordwijk, Netherlands.

The James Webb Telescope has 18 mirrors in total.

The 21-foot, 4-inch (6.5-meter) primary mirror – much too big to fit inside a rocket fairing – is made up of 18 hexagonal, beryllium mirror segments.

The James Webb telescope did unfold without any issues after launch and it's now in operation.

The successor to the James Webb Telescope will be the Nancy Grace, Roman, Space Telescope.

The reason James Webb is at L2 is because it allows the satellite's large sun shield to protect the telescope from the light and heat of the Sun and Earth (and Moon).

The telescope James Webb will orbit the sun 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange point or L2.

The Webb telescope does have cameras.

The James Webb telescope has science cameras like the near Infrared Camera instrument which collects highly detailed infrared images of the universe.

However the Webb Telescope does not have any deployment cameras like the ones Perseverance had on it's landing system.

The James Webb telescope is as far as 1 million miles away and is the largest and most powerful space based telescope that was ever built.

The James Webb telescope is successful.

The James Webb telescope's secondary mirror was then successfully deployed and latched on Jan. 5, 2022.

Then on Jan, 8. 2022, NASA announced that the James Webb Space Telescope had successfully unfolded the giant primary mirror and is now fully deployed.

After launch the James Webb will be operational 6 months after launch.

As of now the James Webb telescope has been launched and is now in operation.

The James Webb telescope is now ready as it's gone through all the testing and commissioning.

The months-long process of preparing NASA's James Webb Space Telescope for science is now complete.

All of the seventeen ways or 'modes' to operate Webb's scientific instruments have now been checked out, which means that Webb has completed its commissioning activities and is ready to begin full scientific operations.

The James Webb telescope is currently at its observing spot, Lagrange point 2 (L2), nearly 1 million miles (1.6 million km).

The James Webb Telescope is the largest and most powerful space telescope ever launched.

The launch date of the James Webb Telescope was on December 25th 2021 at 6:20 AM CST.

The power of the James Webb Telescope is 2,000 watts and cost 10 billion dollars to build and launch.

The James Webb Space Telescope is a space telescope designed primarily to conduct infrared astronomy.

As the largest optical telescope in space, its high infrared resolution and sensitivity allow it to view objects too early, distant, or faint for the Hubble Space Telescope.

Just over a week after NASA dazzled the world with the first clutch of images from the James Webb Space Telescope, astronomers working with one of the pictures believe they have found the oldest galaxy ever imaged—one dating back 13.5 billion years, or just 300 million years after the Big Bang, report Space.com

James Webb's cameras can look deep into space and far into the past.

Webb telescope has the capacity to look 13.6 billion light years distant—which will be the farthest we've ever seen into space.

The James Webb Space Telescope's first year of observations promises to reveal exoplanet atmospheres and surfaces, infant galaxies, and maybe even the first black holes.
