No it's not.
Earliest launch date is 2018, clearly it is NOT "mostly ready to go".
Now go back and re-read what I actually said.
Or do you think that the Technology is the only piece of this puzzle?
Interesting.
What - you think they shoot a bunch boxes, some mirrors, and some solar panels up into space, without testing them, and hope that they'll withstand the cold, the vacuum, the radiation, and somehow manage to spontaneously organize themselves into a Space Telescope?
Really. I gave you more credit than that.
The longer it takes, the more it costs, their run rate is over 1 million per day.
No. The report says that was not the only problem by far. Indeed it points to their major bugeting problems at the point of the Confirmation review in 2008, 6 years after the general contractor was chosen.
Yeah, remember this post:
http://sciforums.com/showpost.php?p=2777387&postcount=3 where I linked to the Casani report.
First off, I don't recall suggesting that it was the
only issue.
Secondly, even with some modest research you can find members of the astronomical community, who voiced right from the get-go, when the JWST was going to be a 500M USD project with an 8m mirror who got clipped upside the back of the head for suggesting as much.
Apparently, the only people who believed they could do it were NASA. So no, the budgeting problems existed before the confirmation in 2008, but they may not have become apparent before then.
Separate issue, but it is related.
NASA will hopefully learn from their mistakes.
The Casani report made a series of reccomedations to fix the problem and reign in the cost.
The House Appropriations Comittee chose not to fix the problems, and can the project instead.
Not according to the report. Indeed the project didn't start until after 2000, so budget issues from 1990 to 2000 have no bearing at all on their problems.
Bull-pucky.
If NASA's budget had been maintained at 1990 levels over the last 8 years, there would have been an extra 3 Billion USD available, but no, they were cut back from 19.7 Billion in 1991 to 14.9 Billion in 2000, and held in the 15-16 Billion USD range between 2001 and 2007.
The JWST was first proposed in 1989 (as the NGST) as a successor for Hubble, because Giacconi (director of the STSci at the time) realized that it would take about 20 years from conception to launch. In 1993, the Dressler report reccomended extending the lifetime of the HST to 2010 and putting a 4m telescope in a low background orbit, in 1994 Hi-Z was proposed. In 1995 Goldin took the helm with his "Faster, Better, Cheaper" mantra, and pushed them to consider an 8m Telescope, and in 1996 a report was published that laid out the roadmap for the NGST for the next decade. By 2000, they had already ruled out a 2000 launch because of the mirror schedule, and the cost was already several hundred million over budget.
It was
because of these
already existing budget problems, and the realization of future technological (and I believe budget) problems that in 2001 the Telescope mirror size was reduced from 8m to 6.4m.
So yes, I think it is entirely relevant to consider the funding conditions of the '90s as part of the problem.
Note, after confirmation the NASA project managers commit to
complete the development based on the expectation of a reasonably bounded Life Cycle Cost and a firm launch date, but:
So they are saying after they had worked on it for 6 years, they submitted a flawed budget to complete the project.
I'm aware of how the planning process is
supposed to work, thankyou.
The underestimated their confidence intervals on the budget - IE they lowballed it.
Note that Sen. Mikulski, the Senator that wrote the latter requesting the review that resulted in the Cassani report, still supports the JWST, thinks it should be allowed to go ahead, and thinks that cancelling it is short sighted, and will set back American technological and scientific advance substantialy.
You keep focusing on that 1.6 billion. The JWST was cancelled because it's launch date and life cycle costs kept going out and up, and they need almost $4 Billion to complete, based on a launch by 2015, but the reality is the latest estimate of the launch date is now out to ~2018, and thus the cost would likely be another couple of billion over that.
Go back and re-read the report - they need an
additional 1.6B USD on top of the 4.5B odd the originally projected in April 2006, after the replanning started in August 2005 they did as a result of cost growth revealed in Spring 2005.
Not to that level of specificity. We have a representative government and we expect them to make the right decisions in these matters as the public has not the level of understanding of NASA or the mission or the problems to make those kind of specific decisions.
Only the experts didn't reccomend canning the project, did they. A Senator did, because it was over budget and behind schedule. The report came to the conclusion that the most cost effective way of fixing the project was to sink a little extra money into it now so that the defered work could be completed, and to
fix the management structure, allowing the project to go ahead.
They commissioned a talented group to study the program and after that study came to the conclusion that continuing it was not in our best interests at this time.
They commissioned a study, and then chose to ignore the advice given to them, and instead follow the lead of the Tea Party (whos views on the matter align with yours). Meanwhile, the AAS, AURA, Sen. Mikulski, and Sen. Polis all seem to support the completion of the project (they're the one's I've been able to identify in the little time I have anyway - I get the impression there are a number of others as well, support for the project is widespread).
What makes it worse is this: It's not just NASA that's had its funding cut, it's science. It's NASA, NSF, NOAA, and NIST, have all had their funding cut, or reduced from what Obama requested.
