FILE - This 2015 artist's rendering provided by Northrop Grumman via NASA shows the James Webb Space Telescope. On Thursday, May 30, 2019, the U.S. Government Accountability Office reported that NASA's major projects are more than 27 percent over baseline costs and the average launch delay is 13 months. That's the largest schedule delay since the GAO began assessing NASA's major projects 10 years ago. The still-in-development James Webb Space Telescope is the major offender.
