Funds Restored to Build the James Webb Space Telescope

The U.S. House of Representatives, which had proposed terminating NASA’s next-generation space telescope, voted today to reverse course and fund the massive project. The James Webb Space Telescope, designed to succeed the Hubble Space Telescope as NASA’s primary orbital observatory, would receive $529.6 million for the fiscal year ending September 30, 2012, under the new plan.

In July the House subcommittee responsible for NASA’s funding released its draft budget, which would have eliminated the Webb telescope, or JWST, noting that it was over-budget by billions of dollars and claiming that the project was “plagued by poor management.” But the Senate wrote into its budget more than half a billion dollars to keep JWST on track for a 2018 launch. (That timeline has slipped considerably during the telescope’s development; the planned launch date was 2014 as recently as 2010.)

Today the House passed a compromise version of the appropriations legislation which funds NASA and several other government agencies by a vote of 298–121. The compromise, or conference report, included the Senate’s full funding request for JWST. Hours later the Senate signed off as well by a vote of 70–30.

“It’s certainly a major improvement in our position,” says NASA’s John Mather, senior project scientist for JWST and winner of the 2006 Nobel Prize in Physics. “Especially considering that not too many months ago one of the subcommittees voted to give us zero dollars.”

Overall the budget bill grants NASA $17.8 billion, a decrease of more than half a billion dollars from last year’s levels. The latest JWST cost estimates, which exceed $8.8 billion over the entire course of the project, mean NASA will have to cut back elsewhere. The agency’s budget, as detailed in the conference report (pdf), includes reductions from what President Obama had requested for Earth and planetary science, astrophysics and institutional management—all to accommodate JWST. The appropriations legislation also includes $1.2 billion to continue developing the Orion crew capsule, as well as $1.86 billion to work on a congressionally mandated heavy-lift rocket called the Space Launch System.

The estimated cost and launch date of JWST have been moving targets, but advocates have stressed that the telescope is on solid ground technologically. “All 18 of the primary mirror segments have been polished and tested, and we’re very happy with them,” Mather says. “The parts that were the hardest ones have been finished.”

If JWST can keep dodging legislative cost-cutting and finally take flight toward the end of the decade, it will take up a position well beyond the orbit of the moon to peer deeper into the universe than ever before with a giant, 6.5-meter mirror designed to corral faint infrared light. “The telescope does something that no one could ever tackle before,” Mather says. “There’s no competition in the past and there’s nothing planned for the future, as far as I know. It’s unique, it’s irreplaceable, it’s the only one.”

    Wholly mugger of sod! Well, we need all that money for bail outs, CEO bonuses and war contractors! Congrats on saving the scope, though. Man, these are tough days for rational ppl and science! CHEERS!

    Outside the orbit of the moon?!!! Most excellent. Deep, deep space.

    China now seems to lead the world in all scientific endeavours. Just study all the research papers published worldwide.

    Since the Webb Telescope will have an orbit out past the moon, what will happen if (like Hubble) the telescope needs servicing? Since only the Air Force has a shuttle program will they be charged with the service calls? But wait a minute, the shuttles were never designed to go that far. Or were they…?

    On the other hand, could NASA be planning on the new heavy lifter or the Orion system as the servicing systems?

    Service and repair of any system must be taken into consideration. Why does not this article address that?

    Inquiring minds want to know.

    Dear AtlantaTerry ,
    The Hubble Telescope required servicing and was designed for this,the James Webb Telescope is designed to NOT need servicing.

    For the simple reason that it is so far away from Earth that servicing is impossible.

    The James Webb is being built about 30 years after the Hubble was.
    Lot of progress in technology in that time and the knowledge that the components should be given more than one check to ensure that everything works as designed.
