James Webb Space Telescope Project on Track but May Benefit from Improved Contractor Data to Better Understand Costs, GAO

"JWST continues to meet its cost commitments, but unreliable contractor performance data may pose a risk to project management. To help manage the project and account for new risks, project officials conducted a cost risk analysis of the prime contract. ... GAO found that while NASA's cost risk analysis substantially met best practices for cost estimating, officials do not plan to periodically update it. ... Further, the project does not have an independent surveillance mechanism, such as the Defense Contract Management Agency, to help ensure data anomalies are corrected by the contractor before being incorporated into larger cost analyses, as GAO recommended in 2012. As a result, the project is relying partially on unreliable information to inform its decision making and overall cost status."

ESA and Arianespace Sign James Webb Space Telescope Launch Contract

"The JWST is a joint project of NASA, ESA and the Canadian Space Agency. Europe's contribution includes the Ariane 5 launch, along with two of the four state-of-the-art science instruments optimized for infrared observation of the Universe, and support for scientific operations."

Hawaiian court revokes permit for planned mega-telescope, Nature

"Hawaii's supreme court has ruled that the construction permit for the Thirty Meter Telescope (TMT) atop the mountain of Mauna Kea is invalid. The 2 December decision is a major blow to the international consortium backing the US$1.5-billion telescope, and a win for the Native Hawaiians who have protested its construction on what they regard as a sacred summit. Hawaii's Board of Land and Natural Resources should not have approved the permit in 2011, the court said, because it did so before protestors could air their side in a contested case hearing. "Quite simply, the Board put the cart before the horse when it issued the permit," the court decision reads. "Accordingly, the permit cannot stand." It is unclear whether and how the TMT will move forward given the new ruling."
