The U.S. Government Accountability Office (GAO) released the following report and testimony today, all worth a read:

1)

NASA: Assessments of Selected Large-Scale Projects. GAO-15-320SP, March 24.

In 2015, five of NASA’s largest, most complex projects, several of which are at critical points in their development, are expected to consume 78 percent of the funds for NASA’s major projects.

Therefore, existing and new projects will be competing for remaining funds.

GAO reports that the James Webb Space Telescope (JWST) project is now in the early stages of its extensive integration and testing period. Maintaining as much schedule reserve as possible during this phase is critical to resolve challenges that will likely surface and negatively impact the schedule.

JWST has begun integration and testing for only two of five elements and major subsystems.

While the project has been able to reorganize work when necessary to mitigate schedule slips thus far, the GAO reports that this flexibility “will diminish as work during integration and testing tends to be more serial, as initiating work is often dependent on the successful and timely completion of the prior work.”

    Thanks Leonard. Wish I could ‘come back’ after a million or 2 years to check out our progress in the cosmos.
