Friday’s CSExtra offers the latest reporting on space activities from around the world. At NASA’s Kennedy Space Center, experts close in on the source of shuttle Discovery’s hydrogen leak. A national deficit reduction commission takes aim at NASA’s bid to foster commercial space transportation. More on the moon, dark matter and signs of change on Jupiter.
1. From Spaceflightnow.com: On Thursday, technicians found an unevenly compressed seal within the leaky external tank vent line fitting that brought a halt to shuttle Discovery’s Nov. 5 launch attempt from the Kennedy Space Center. A replacement of the entire assembly is under way, and NASA is taking other steps to prepare for a future launch attempt, possibly as soon as Nov. 30.

From Florida Today: Supporters of NASA’s commercial space transportation initiative, part of the agency’s 2011 budget, are unhappy with a recommendation from the National Commission on Fiscal Responsibility and Reform. The Commission suggested changes earlier this week to reign in the budget deficit, including a proposal to cut NASA assistance to the commercial spaceflight industry.
