What is the greatest benefit of using the Hubble Space telescope?

The Hubble telescope provides four key advantages over most other optical astronomical facilities: unprecedented angular resolution over a large field, spectral coverage from the near infrared to the far ultraviolet, an extremely dark sky, and highly stable images that enable precision photometry.

How much would it cost to buy the Hubble telescope?

Revealed: The ‘Next Hubble’ Space Telescope That Will Photograph Another Earth, Cost $11 Billion And Launch In The 2040s.

Who paid for James Webb telescope?

NASA’s contributions to the telescope were not paid out all at once, but spread out over the course of two decades. Annual expenditures vary depending on the particular needs of the project and how many highly-trained technicians, engineers, and scientists are assigned to the program at any given time.

What is the most expensive telescope to buy?

James Webb Space Telescope
NASA’s $8.8-billion James Webb Space Telescope, the world’s largest and most expensive one, has successfully passed final thermal vacuum test, making its parts cleared for use in space.

Which of the following explains the advantage of the Hubble space telescope compared with ground-based telescopes?

Hubble’s second huge advantage is its ability to observe near-infrared and ultraviolet light, which is otherwise filtered away by the atmosphere before it can reach ground-based telescopes. Find out more about the spacecraft Hubble and see images of it in flight.

How much did James Webb telescope cost?

10 billion USD (2016)
James Webb Space Telescope/Cost

Why is a telescope so expensive?

It is recognized as a long tube that increases in length until it gets to the lens. This lens requires special crafting, which is why they are so expensive. These types of telescopes use mirrors where the objective lens would be in refractor telescopes but are also more common than the latter.

What company makes the best telescopes?

How much did the Hubble Space Telescope cost to build?

With NASA on board, the next step for what would become the Hubble Space Telescope was to obtain federal funding for the project. Unfortunately for the program, the large space telescope’s total cost was roughly estimated at $400 to $500 million, making it a tough sell.

What happened to the Hubble Space Telescope on STS 103?

Servicing mission 3A in December, 1999 replaced all six of the telescope’s aging gyroscopes, which accurately point the telescope at its target. STS-103 astronauts also replaced one of the telescope’s three fine guidance sensors and installed a new computer, all in time to redeploy Hubble into orbit on Christmas Day.

What happened to Hubble’s Wide Field/Planetary Camera?

During the EVAs, COSTAR was installed and the Wide Field/Planetary Camera was replaced with the Wide Field/Planetary Camera 2, which was designed to compensate for the mirror problem. The team also performed basic maintenance on the craft, installed new solar arrays, and replaced four of Hubble’s gyroscopes.

How much did the large space telescope cost in 1975?

The ESRO accepted the offer in 1975. A mirror reduction from 3 to 2.4 meters helped bring the project down to about $200 million, approximately half the originally expected price tag. The proposal was accepted by Congress, which granted the Large Space Telescope program funding in 1977.
