Hubble Successor: U.S. Senate Decision Pulls The James Webb Telescope Out of Deep Trouble

Some great news is coming in from Washington! The James Webb Space Telescope (JWST) may just have got a new lease of life.

Money and relief

We reported that the JWST was cancelled (here) due to fund cuts by the US Senate Appropriations Sub-Committee. Yesterday (14th September), the US Senate Appropriations Committee met to discuss the details of the FY2012 (Financial Year 2012) bill and, surprise and glee, the JWST was sanctioned $530 million in 2012. This is a big improvement over the $374 million it was sanctioned in the last year.

This will be music to many ears, both intimately associated with the JWST project and other space enthusiasts. Hubble has been as much a darling for the public as for professional astronomers, and it would just be a shame if it had no successor. Losing the joy of watching deep space in high resolution, never knowing what one will find is a joy unparalleled! No one wants that to end.

The continuing construction of a wonder

Recently the James Webb Space Telescope completed a crucial phase in the construction of its mirrors. It has 21 mirrors, made up of 18 segments, forming one giant 21 foot mirror. The mirrors are the best in the world. They are made up of beryllium, so that they can withstand the near absolute zero temperature of space. They are also coated with a thin film of gold so that they are good reflectors of infra-red radiation. All of this goes into making JWST at least a 100x better than Hubble ever was.

The 21 foot mirror!

Please note that JWST is not out of the woods yet! This is merely the money granted for 2012. The project will last till 2018 and there are still many hurdles ahead, especially for a project of this magnitude where the costs tend to swell up abruptly.

Apart from this grant to the JWST, NASA got a grant of $17.9 billion for the coming year. Although this is a $500 million reduction from the promised grant, it is still a hefty amount.

The champagnes must be flowing in the JWST camps.
