There are 2 key pieces of electronics aboard HST that if they were to fail would essentially end HST's service life:
Fine Guidance Sensors (FGS) are arguably the single most key pieces of electronics on HST. The FGS's are what point HST and keep it locked in position while observations are being made, a difficult task considering that HST orbits the Earth every 96 minutes, and is subject to extreme thermal stresses every time it passes through the solar terminator (the line between darkness and sunlight in orbit).
Science Instrument / Command & Data Handling Unit (SI C&DH) - The very first item I worked on during my years with the HST program, the SI C&DH converts all science data from HST observations prior to relaying to the ground via telemetry. Without this key unit, data from Hubble could not be transmitted to the Space Telescope Science Institute in Maryland (HST's control center), and HST's function would be useless. There are 2 SI C&DH units, one primary and one backup. One failed just prior to the last servicing mission; it was delayed so a spare unit (there are always at least 1 or 2 flight units available on the ground, or if necessary an engineering unit can be made flight-ready) could be readied and the Astronauts could prepare for replacing this key unit.
There are a number of differences. First, they are in different orbits; the Hubble is higher than the ISS. The ISS is a lot bigger. Probably the most important difference is that the Hubble has a big telescope but no people, while the ISS has people but no big telescope.
The Hubble Space Telescope is the most famous and the best working EVER MADE!
The first large space telescope was the Hubble, and it's probably still the most famous one. But a LOT of the new and exciting work being done is using the Kepler Space Telescope, a device which was specially designed to search for planets around neighboring stars.
NASA's most famous telescope is probably the Hubble Telescope that orbits the earth.
The most powerful telescope is the Hubble telescope, please note you did not ask where.
It is the one kind of telescope use in space. The Hubble Space telescope, is the one of the most common used-technology in space. The Hubble Space telescope was named after Edwin Hubble.
It is the Hubble Space Telescope.
the Hubble space telescope
The Hubble telescope is unique because it was the first space telescope. Also, the Hubble is one of the largest and most versatile.

There are several, perhaps most notable is the Hubble Space Telescope.

The Hubble Space Telescope was launched into orbit aboard NASA's space shuttle Discovery (mission STS-31) on April 24, 1990.The Hubble Space Telescope was originally meant to be launched in 1986, but the explosion of the space shuttle Challenger delayed the launch until April 24th 1990.The Hubble telescope is now seen as one of the most versatile telescopes in space. After it was launched in 1990, astronomers had a chance to change and improve the telescope through missions by astronauts aboard the Space Shuttle.

it should be the hubble space telescope because it can see 10 times better than a normal telescope
