When It Is Launched In December The James Webb Telescope Will Be Facing 'Two Weeks Of Terror'

So much could go wrong, but the engineering teams believe they have all eventualities covered 

BBC: James Webb: Hubble telescope successor faces 'two weeks of terror' 

Engineers like to describe the process of landing a rover on Mars as the "seven minutes of terror". 

That's how long it takes for a robot to come to a standing-stop at the surface of the Red Planet after entering the atmosphere faster than a rifle bullet; and so much has to go right in-between to avoid smashing into the ground. 

But when it comes to the James Webb Space Telescope (JWST), it's more like "two weeks of terror". 

The successor observatory to the mighty Hubble telescope has been built to see the very first stars to shine in the Universe.

CSN Editor: This new telescope took years to assemble at a cost of $10 billion. So yes. This launch and deployment better work out.

James Webb Space Telescope Arrives At Europe's Kourou Spaceport To Be Prepped For Launch

BBC: $10bn James Webb Space Telescope unpacked in Kourou 

Engineers have unboxed the James Webb Space Telescope in French Guiana and will now prepare it for launch. 

The $10bn successor to the Hubble observatory arrived at Europe's Kourou spaceport five days ago after being shipped from the US. 

It's now been relieved of its transport container and raised into the vertical to allow preflight checks to begin. 

JWST is one of the grand scientific projects of the 21st Century and will ride to orbit on 18 December.

Webb Telescope Survives Spending Cuts

It's Alive! The Greatest Space Telescope Ever Built Survives -- Time

When last we heard about the James Webb Space Telescope, the souped-up, long-planned successor to the Hubble, the news was not good. Hard on the heels of a report blasting the Webb project for being badly behind schedule and over budget, a House committee voted to axe the partially completed telescope entirely.

Even a space nut could appreciate where they were coming from: originally envisioned in the 1990s as a monster scope 26 ft. (8 m) across, with more than 17 times the light-gathering power of the Hubble, the Webb was going to cost no more than $500 million and launch by 2007 — cross NASA's heart and hope to die! No one really bought that, but no one really expected the budget to swell to $2.6 billion and then to $6.2 billion, or the launch date to slip to 2015 and then 2018 either. When all that did happen, D.C. bean counters concluded that nothing would become the Webb project quite as much as the end of it.

James Webb Space Telescope To be Scrapped

Will Cost Kill Hubble’s Successor? -- Cosmos

A plan to scrap the James Webb Space Telescope, the long-awaited and costly heir to NASA’s Hubble telescope.

TOUTED AS NASA'S replacement for the ageing Hubble Space Telescope, the James Webb Space Telescope, if deployed, would be 100 times more powerful than its iconic predecessor.

"It will have incredible sensitivity and spatial resolution, making it able to look back to the very earliest times in the universe," says Warrick Couch, an astronomer at Swinburne University of Technology in Melbourne.

Yet funding cuts now seriously threaten the telescope's future, already over budget and years behind schedule, with bleak implications for future U.S. investment in astronomy projects of this scale.

Will Budget Woes Kill NASA's Next Great Telescope?

After Hubble: Will Budget Woes Kill NASA's Next Great Telescope? -- Time

Over the past hundred years or so, the science of astronomy has been utterly predictable, in an utterly unpredictable sort of way. Decade after decade, telescopes got steadily bigger and more powerful, and expanded their range beyond ordinary visible light into the hidden realms of ultraviolet, infrared, radio waves and more. And with every one of those leaps, astronomers discovered something unexpected and astonishing — massive black holes spewing blasts of energy into space, tiny neutron stars spinning a thousand times a second, dark matter pushing galaxies around like toys, and even the afterglow of the Big Bang at the dawn of time.

Pursuit Of The Universe's First Galaxy

In Pursuit Of The Universe's First Galaxy -- CBS News

If all goes according to plan, the James Webb space telescope will take to the stars in 2014. And scientists are counting down the days. The Webb is expected to offer them unprecedented views of the cosmos. The heir to the Hubble space telescope, the upcoming telescope has been taxed with a big job during its planned five-year space mission: no less than the job of photographing some of the universe's first-ever galaxies. With a 21-foot mirror, the Webb telescope will be powerful enough to take aim at the oldest stars and galaxies in the universe.

My Comment: I suspect that the discoveries that it will find will rewrite the book on the origins of the universe.

Nobel Physicist: Building Hubble's Heir In Deep Space

From New Scientist:

When the James Webb Space Telescope unfurls its mirror a million and a half kilometres out in space four years from now, it will be the culmination of nearly two decades of planning by John Mather. He tells Anil Ananthaswamy about the challenges of building an heir to the stunningly successful Hubble Space Telescope

Why do we need the James Webb Space Telescope, when Hubble is still up there?

The short answer is that Hubble has tantalised us by showing us signs of things that would be really exciting to know about, but are just beyond its reach.

Hubble's Replacement Now Taking Shape

Technicians gingerly handle the honeycombed beryllium mirror segment that will eventually join 17 others to form the primary mirror of the James Webb Space Telescope. Axsys

From SKY Telescope:

Against a backdrop of the worst financial crisis since the 1930s, no one quite knows what will happen to NASA's future plans once Barack Obama becomes president. Will Michael Griffin remain the agency's chief? Will plans to return astronauts to the Moon be scrapped? Will space exploration in general — viewed by some as frivolous waste and by others as a ray of accomplishment amid all the bleakness — be slashed to a bare minimum?

We'll know soon enough. In the meantime, NASA continues to work toward assembling and launching the eventual replacement for the Hubble Space Telescope, currently the crown jewel of its astronomy program.
