NASA's Big Telescope Avoids Death-by-Budget-Cut

coondoggie writes "NASA's most ambitious and highly over-budget space projects, the James Webb Space Telescope has apparently been spared the budgetary axe. The US Senate Committee on Appropriations has approved about $530 million of NASA's $17.9 billion budget to 'enable a 2018 launch of the James Webb Space Telescope.'"

There's a guy (featured on Slashdot last week) that may throw some light on those figures:

The original cost estimate was $5.1 billion, and included the first five elements only. The 2013 launch date was never settled upon, and the optimistic estimate associated with the $5.1 billion figure was 2014. When the cost went up to $6.5 billion and the launch date got pushed to 2015, that was really NASA's fault. I don't want you to come away with the impression that NASA is blameless in this; there really was budget mismanagement. This happened last year.

How did it happen? As my source tells it,

During 2010 the project held its next major review: the Critical Design Review. By this time the 2014 launch date had started to appear not credible. Therefore, Senator B. Mikulski, chair of the appropriation subcommittee responsible for NASA, called for an independent review of the project in the Summer 2010. The Independent Comprehensive Review Panel found that the project had not been properly managed, primarily due to the lack of near term reserves which for a project of this complexity are needed to make sure that things stay on track when issues are discovered.

In other words, the mismanagement was primarily not keeping enough cash-on-hand to deal with unexpected issues when they came up. This resulted in a new figure of $6.5 billion and a new launch date of 2015.

BUT!

This is important. The Independent Comprehensive Review Panel, when it came up with the $6.5 billion / 2015 figure, said that it was contingent. Upon what?

The ICRP conclusion was that the earliest JWST could be launched was late 2015 for a total cost of $6.5B of which $250M extra had to be provided in each of 2011 and 2012. They stated clearly that this was the earliest and cheapest way to launch JWST and any delay would result in a more expensive mission.

The 1B figure seems to be a gross underbid, according to other sources which
