Astronomy Science ~ Hubble Space Telescope was old, at least by the standards of technology. This telescope began orbiting the Earth nearly 25 years ago, long before we have things like the iPhone and smart phones. And when Hubble fixed in space, the equipment also becomes obsolete and its ability also will stop operating.

So what happens to the Hubble when it reaches the point of no longer function? The answer is Hubble may be defeated by gravity and then fell to Earth, burning in the atmosphere on the way down.

During the space shuttle program, astronauts updating Hubble, using a telescope toward the spacecraft. Once there, they are fixing the equipment and install new technology. NASA scheduled the last mission in 2005.

However, after the space shuttle Challenger exploded upon entry to Earth, NASA plans change. There is a concern because the astronauts will repair Hubble has no "plan B" if anything goes wrong with the shuttle, the mission was too dangerous.

But Hubble desperate need of repair because of its ability to drop to 20 percent. So in 2009, the Hubble telescope finally received treatment and update the device. The mission, dubbed STS-125, involves a lot of work, but eventually, Hubble is 100 percent fully functional.

That was the last time we've heard about a mission to repair and maintain the Hubble. And now, the ability of this telescope to decline again. Each shake and vibration make it down in orbit. Eventually, it will fall out of orbit and back to Earth.

"Its orbit will decay," said Mike Massimino, one of the astronauts on STS-125. "This telescope will be fine, but its orbit will bring it closer and closer to Earth. It was then game over." Of course, NASA could send a mission to push it back into a stable orbit, but the problem is the NASA has not expressed a desire to do it.

A new telescope, the James Webb Space Telescope (JWST), launched in 2018 and will orbit 900,000 miles away from Earth, allowing the telescope to look farther than Hubble. May not make sense to create a schedule that is potentially dangerous mission to repair the Hubble and fix its orbit during the launch of JWST is in sight.

So the Hubble repair mission is impossible, like what is fate? Most likely, because of its size, this telescope NASA should help when falling to Earth, adjust them so that some parts of the structure, especially large mirror, which can withstand high temperatures, do not hit anyone on the surface.

The telescope is expected to operate until 2020. For me the Hubble telescope can enter in the magic world and thanks to hubble, we can see further in the Universe and plays a major role in improving our understanding of astronomy.

Thank you Hubble telescope !!
