Can Hubble Be Serviced Again?

How far is Hubble from Earth?

about 547 kilometersThe Hubble Space Telescope is a large telescope in space.

It was launched into orbit by space shuttle Discovery on April 24, 1990.

Hubble orbits about 547 kilometers (340 miles) above Earth..

Are there colors in space?

Space emits a range of wavelengths of light, some we can see others we can’t. … Even the Hubble Space Telescope which has been capturing the most amazing space images that we have witnessed so far doesn’t really see any color and only takes pictures in black and white.

How far can the Hubble telescope see?

about 10-15 billion light-yearsThe farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field.

What were the last fixes to Hubble?

The Hubble Space Telescope was reborn with Servicing Mission 4 (SM4). The fifth and final servicing of the orbiting observatory flew aboard space shuttle Atlantis (STS-125) May 11–24, 2009. During SM4, two new scientific instruments were installed — the Cosmic Origins Spectrograph (COS) and Wide Field Camera 3 (WFC3).

Is Hubble visible from Earth?

Hubble is best seen from areas of the Earth that are between the latitudes of 28.5 degrees north and 28.5 degrees south. This is because Hubble’s orbit is inclined to the equator at 28.5 degrees. … So northern parts of Australia have great access to seeing the HST and can catch the telescope flying right overhead.

How much did the Hubble cost?

It took two years before shuttle flights could resume and NASA could begin planning Hubble’s launch again. The world’s first space telescope finally launched aboard space shuttle Discovery on April 24, 1990. The effort cost $1.5 billion, but there would be ongoing costs — both expected and unexpected.

What will replace Hubble telescope?

Overview. Webb often gets called the replacement for Hubble, but we prefer to call it a successor. After all, Webb is the scientific successor to Hubble; its science goals were motivated by results from Hubble. Hubble’s science pushed us to look to longer wavelengths to “go beyond” what Hubble has already done.

How much longer will Hubble last?

Originally required to last 15 years, Hubble has now been operating for more than 28. The final servicing mission in 2009, expected to extend Hubble’s lifetime an additional 5 years, has now produced more than 9 years of science observations.

Are Hubble telescope pictures real?

Iconic Hubble images are actually black-and-white. Any iconic image of the universe you can think of was probably taken by the Hubble Space Telescope. Take the Eagle Nebula, for example, which is shown below. What you might not realize is that this spectacular, colored photograph was originally black and white.

Who owns the largest telescope in the world?

China spent $180 million to create the telescope, which officials have repeatedly said will make the country the global leader in radio astronomy.

How much did it cost to fix the Hubble telescope?

NASA officials have put the cost of the servicing mission at $251 million. That includes the new corrective optics, equipment testing, software development and replacement of other faulty or worn-out equipment on Hubble.

What can’t the Hubble observe?

That also means that Hubble can’t observe Mercury, Venus and certain stars that are close to the sun either. In addition to the brightness of objects, Hubble’s orbit also restricts what can be seen. Sometimes, targets that astronomers would like Hubble to observe are obstructed by the Earth itself as Hubble orbits.

How do you spot a satellite?

How Can I See an Overhead Satellite?First, you can spot satellites without any instrument at all, but it helps to have a good pair of binoculars. … Choose a chair that allows you to recline comfortably and orient it so you can see a wide expanse of the sky. … Sweep slowly across the sky, pausing occasionally to focus on one area.More items…

What was wrong with Hubble’s mirror?

Shortly after the Hubble Space Telescope’s launch in 1990, operators discovered that the observatory’s primary mirror had an aberration that affected the clarity of the telescope’s early images. … The result was a mirror with an aberration one-50th the thickness of a human hair, in the grinding of the mirror.

How did they fix Hubble?

NASA sent up astronauts in the space shuttle Endeavour to manually repair the telescope. Five space walks later, the astronauts completed the repairs. They installed a device containing 10 small mirrors that intercepted the light from the primary mirror and corrected the pathway to the sensors.

How much would Hubble weigh here on earth?

The total archive is currently over 150 TB in size. Hubble weighed about 24,000 pounds at launch but if returned to Earth today would weigh about 27,000 pounds — on the order of two full-grown African elephants. Hubble’s primary mirror is 2.4 meters (7 feet, 10.5 inches) across.

How many galaxies are there?

100 billion galaxiesAll in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told
