Hubble Space Telescope
The Hubble Space Telescope, named for noted American astronomer Edwin Hubble, was built by NASA and launched into orbit aboard Space Shuttle Discovery (STS-31) in April 1990. It can observe the visual, ultraviolet, and infrared light spectrums, and is one of four space telescopes in NASA's "Great Observatories" Program.

To the best of my knowledge and intensive research among all the available photos and videos there is no record telling the exact hour of deployment of the HST. It appears that this information has not been considered of importance.
The EXIF-files of the images of the HST taken during the deployment are not available. There are a few shots showing the HST immediately after deployment with clearly recognizable features of the land below, e.g. Cuba and the Bahamas, in broad daylight. Looking at details of such photos gives an estimated time of about 11 hours local time in Cuba which would be 14 hours GMT (UTC).
Was it worth spending all the money to make the Hubble telescope?
Absolutely - most people only tend to view the science aspect of HST, and not the commercial application advancements that have been made in it's long history. Some of those you're probably familiar with, but don't realize where the development of the technology came from:
Lithium Ion Batteries - Li Ion battery technology was further funded by NASA's Goddard Space Center for the HST/ISS Pistol Grip Tool, used to service the Hubble and construct the International Space Station. Though the design is based on a standard cordless drill (Black & Decker was initially approached for a design, but declined) the power pack is a series of Li Ion cells. The PGT was one key program I was responsible for, and it was initially used in 1997 on the HST 2nd Servicing Mission. Though they still have the same problems we had back then (they tend to overheat occasionally in certain situations) they're still the rechargeable power cell of choice for the masses, and it's only been in the past few years that BD/DeWalt and other companies have started using them in their tools.
Solid State Drives / Flash Drives - SSD's and Flash Drives are a direct result of a Hubble Telescope replacement unit called the Solid State Recorder. Replacing 2 mechanical reel-reel tape drives on HST Servicing Missions 2 and 3A, SSR technology has literally changed the way digital data is stored, eliminating the need for mechanical drives.
Medical Scanning Technology - Much of the enhanced medical scanning technology you're familiar with (CRT's, MRI's, etc.) are directly related to Hubble Telescope imaging technology advancements.
Charge-Coupled Devices (CCD's) - A direct result of Hubble Telescope imaging technology, CCD's are the electronic imaging core of every modern digital camera in use today, digital imaging devices used in medical and industrial applications, as well as satellite imaging.
Composite Materials - There are many carbon and metal composite materials that were originally developed for NASA programs. All spacecraft are manufactured with lightweight composites, and the various materials have improved over the years. Everything from cars to planes have benefited from the technology.
Infrared Technology - Everything from infrared thermometers to IR cameras owes its development to technology developed for astronomical research.
There are some pics on my Supervisor bio page of the PGT and other HST systems, and the link below will direct you to the NASA Spinoff/Innovative Partnerships Program site.
How does the earths atmosphere affect the Hubble telescope?
The biggest change is thermal - since HST moves through the day/nigh terminator in orbit, there is a thermal temperature change of about 500 degrees Fahrenheit every 90 minutes. HST's first set of solar arrays were actually warped by the changes, and were first replaced during the First Servicing Mission in 1993. The current solar arrays, installed during the last Servicing Mission just a couple of years ago, are extremely sturdy and energy efficient; much was learned from the failure and design of the first arrays.
What galaxy did hubble discover?
-- Once you get past our "local group", every galaxy is moving away from us.
-- The farther any galaxy is from us, the faster it's moving away from us.
Why can the hubble space telascope see much further?
The Hubble Space Telescope can see much further than ground-based telescopes primarily due to its location above Earth's atmosphere. This eliminates atmospheric distortion and light pollution, allowing for clearer and sharper images. Additionally, Hubble is equipped with advanced instruments and high-resolution cameras that enhance its ability to detect faint light from distant objects in the universe, enabling observations of celestial phenomena billions of light-years away.
What atmosphere is the hubble telescope located in?
It is above the atmosphere and not in any atmosphere.
Is the Hubble telescope a geostationary satellite?
No, the HST orbits at 570 km above Earth (and not 36,000 km as the geostationary satellites do). It flies round Earth (= one orbit) in 97 minutes, the speed is about 28,000 kilometers per hour.
What is bigger the sun or the hubble telescope?
The Sun; its diameter is 1392684 km while the HST has a diameter of 2.4 m only.
1 Astronomical unit is the mean distance from Earth to Sun and is exactly 149,597,870,700 metres or 92,955,807.273 miles.
Why does the hubble space telesope produce clearer images than those on earth?
The main reason is that it orbits high above Earth's atmosphere which is responsible for the blurring of high-resolution images. Additionally, HST is equipped with hi-tec systems for compensating its own movement, orbiting at 559 km above Earth at 27,000 km per hour. Moreover, many of the fascinating images are composites made at different wavelengths, allowing individual exposures that are perfectly suited for the respective part of the spectrum.
