3, 2, 1…Liftoff of Our 2015 Assessment of NASA’s Major Space Projects!

Posted on April 02, 2015

Each year, we report on the National Aeronautics and Space Administration’s (NASA) major projects. Last week, we issued our latest “Quick Look” report, with updates on projects that are expected to cost at least $250 million. This year, 16 projects met that threshold, and among the 12 with firm budgets, the total expected cost is at almost $19 billion. Read on for our latest findings.

Big Money, Big Risks

Compared to prior years, NASA’s major projects are close to being on target for cost and schedule. The total growth in cost of its 2015 portfolio was 2.4 percent, a smaller increase than last year, and delays averaged 3 months from the original timeframes. In addition, 5 projects did not change from their newly established budgets and timelines.

However, the good news does not extend to the James Webb Space Telescope. NASA has delayed that project’s launch by 52 months, and it is currently $3.8 billion over budget, an amount that has significantly increased the cost of the whole portfolio, as shown below.

We also found that a handful of projects are expected to consume a majority—78 percent—of NASA’s anticipated funds for major projects, and these projects are entering more difficult phases of development. These projects are

Any cost or schedule overruns on these large, complex, multi-billion dollar programs could have cascading effects across NASA’s portfolio—including the potential to postpone or even cancel projects in earlier stages.

NASA is on our High Risk List due in part to problems managing the risks of its major projects. Although the agency has made progress in this area, such as by introducing tools to help project officials anticipate and monitor risks, the agency has struggled with implementing these tools.

About Watchblog

GAO's mission is to provide Congress with fact-based, nonpartisan information that can help improve federal government performance and ensure accountability for the benefit of the American people. GAO launched its WatchBlog in January, 2014, as part of its continuing effort to reach its audiences—Congress and the American people—where they are currently looking for information.

The blog format allows GAO to provide a little more context about its work than it can offer on its other social media platforms. Posts will tie GAO work to current events and the news; show how GAO’s work is affecting agencies or legislation; highlight reports, testimonies, and issue areas where GAO does work; and provide information about GAO itself, among other things.
