Hubble Space Telescope

HST's Science Instrument Control & Data Handling unit (SIC & DH) is the primary system for synchronizing all science instruments, data storage, and processing for transmission to NASA ground controllers.

Scientists have used the Hubble Space Telescope to make numerous groundbreaking discoveries, including the expansion rate of the universe, the age of the universe, and the existence of supermassive black holes. Hubble has also provided detailed images of distant galaxies, nebulae, and planets within our own solar system, leading to a better understanding of the cosmos.

The Hubble Space Telescope was launched in 1990 to provide unprecedented views of the universe from space, free from the distortion of Earth's atmosphere. It was designed to advance our understanding of the cosmos and revolutionize astronomy by capturing high-resolution images and data of celestial objects.

The Hubble Space Telescope was made to observe the universe from space without atmospheric interference, providing clearer and more detailed images of celestial objects. Its design allows it to capture high-resolution pictures across multiple wavelengths of light, helping scientists to study various aspects of the universe such as galaxies, stars, and planets.

HST is made up of many materials, but like all spacecraft/satellites, its primary housing, base structure, and instrument housings are made of a high temper Aluminum Alloy (6061-T3, etc), and in some cases Titanium. All surfaces are corrosion protected (yes, things rust in space, albeit slowly). Those materials make up the bulk of HST's structure. As it is designated a high-visibility program, its QA and Manufacturing standards for all devices is much higher than normal, approaching that of Manned Flight programs. Every solder joint, wire, wire strand, crimp, part, screw, washer, nut, etc., must be individually inspected prior to assembly, and then further inspected as a unit. From personal experience working on the HST program, I can tell you there's no room for error.

During Servicing Mission 3A, we installed a device that's an oddity in spaceflight - the NICMOS Cryocooler unit, which is a high-speed turbine cryogenic pump which pumps liquid helium through the NICMOS cooling tubes used to originally freeze its liquid nitrogen source. Devices with moving parts aren't used on satellites since they can't be repaired, and with HST it's even rarer since moving parts tend to cause vibration, something you don't want on a telescope. However, the NCS turned out to work better than expected, reviving the dead NICMOS camera.

The Hubble Space Telescope orbits the Earth every 97 minutes at an altitude of about 547 kilometers. It travels at a speed of over 27,000 kilometers per hour, allowing it to observe different parts of the sky continuously.

The door on the Hubble Space Telescope covers the aperture to protect the sensitive instruments and optics inside from potential damage when not in use. By keeping the aperture covered when not observing, the door helps to shield these components from hazards such as micrometeoroids and sunlight that could degrade its performance.

The Hubble Space Telescope orbits Earth at an altitude of about 547 kilometers (340 miles). It does not travel through space like a spacecraft on a journey to another celestial body, but continuously orbits Earth in order to observe the universe.

HST didn't get extra panels; the original arrays were replaced during HST Servicing Mission 2 in 1997, due to extreme warping of the arrays caused by thermal changes in space as HST moved through the Earth's terminator (the point in orbit where night becomes day, and day becomes night) every 97 minutes.

The replacement arrays were themselves replaced on one of the last 2 servicing missions, to ensure power for as long as possible until HST is brought down in the next few years.

if you are looking at space from earth with a telescope your view will have to go through the earth atmosphere.... and for that the less brighter object in space will be blocked by the atmosphere... polutions etc....

but space telescope like hubbles... etc are situated in outer layer of our earth atmosphere..... thats why through it we can observe much clear space view....

Water cannot move freely if it is contained or obstructed by physical barriers such as walls or containers. Additionally, factors like gravity, surface tension, and viscosity can influence the movement of water in various directions.

The answer is very simple: ANY telescope on earth, under the best possible circumstances, is looking through earth's atmosphere. Imagine trying to see the fine detail in anything looking up at it from the bottom of a swimming pool. That's an earthbound telescope. The Hubble does not have any atmosphere affecting it's view - which gives it 20/20 or better vision. Earthbound telescopes? 20/40 on their very best nights, usually more like 20/60.

According to internet record it is or was 347 miles, had a gross weight of 24.500 lb and velocity at 25.000 ft/sec. The accelleration of g at that altitude would then be 27.23 ft/sec/sec.

The Hubble Space Telescope is a space telescope, not a space station or a space shuttle. It was launched into space in 1990 and orbits the Earth, capturing images of the universe. The telescope has provided valuable insights into the cosmos and has been serviced multiple times by space shuttle missions.

Yes, the Hubble Space Telescope was launched with a flawed primary mirror rather than a missing lens. The mirror had a manufacturing error that affected its shape, leading to blurred images initially. This was rectified through a repair mission in 1993, successfully improving the telescope's performance.

The Hubble Telescope is a freely moving object sent into space by NASA to take pictures and make observations in space, especially in areas not easily accessible with telescopes. There are more than one Hubble Telescope, such as those in deep space versus ones that are fairly close.

Nope. It is moving too fast around the Earth to get a clear shot. It is designed to take pictures of things far away that are not moving quickly past its field of view, so anything on the ground would be a total blur.

The Hubble space telescope has no interfering forces and it's design enables it to capture more things also the people at NASA take a tiny sand grain size dot of the picture it took and they enlarge it which shows even more stuff!

The Hubble Space Telescope can see objects billions of light-years away, allowing it to observe distant galaxies, nebulae, and other astronomical phenomena. Its high-resolution images have provided valuable insights into the universe's history and evolution.

It's subjective, but many consider the Hubble Space Telescope as one of the best space inventions. Hubble has provided groundbreaking insights into our universe, including discovering new planets and galaxies, and has revolutionized our understanding of space.

It is first mentionned in writing by Ptolemy in the second century AD, however some believe that it was actually named by Hipparchus approx 120BC. It is unlikely that whoever discovered it when will ever be known

gud aftrnoon me kmal 4rm India we can definitely takes the admission in nasa if we hav gud knwledge about particular subject n having n believe that we can achieve this definitely example;u studying msc n u hav a tedency to achieve some different thing than others. its does NT mean u can achive this thing by read other books ,bcoz its easy to rad or follo other philosphies but we also hav own mind power n we can do other things to improve the knowledge of others and to see the future

Not very different.

We lived - quite happily - for many many centuries without them.

What they have done, mainly, is to speed up previously available processes - such as weather forecasting, communications, and scientific monitoring of the planet.

You'd lose your GPS systems, but maps were fine for many people.

You'd lose instant TV pics from the other side of the world, but would that matter too much?

You'd lose the Hubble space telescope - and that's serious, but not a major impact on most people's lives.

The Spitzer Space Telescope was not invented by a single individual. It was a collaborative effort involving NASA, the Jet Propulsion Laboratory, and multiple other organizations. The telescope was named after astrophysicist Lyman Spitzer Jr., who first proposed the idea of space telescopes in the 1940s.

They haven't. Hubble is still goes around Earth once every hour and a half, and continues to take pictures. When it is too old, and all it's cameras fail, it will fire its small rocket engines and crash into Earth's atmosphere, where it will burn up. This will probably occur above the Pacific Ocean in the next 5-6 years.
