With just under 4 years until its planned launch in October 2018, the James Webb Space Telescope (JWST) project reports it remains on schedule and budget. However, technical challenges with JWST elements and major subsystems, have diminished the project's overall schedule reserve and increased risk, says a
new report released by the Government Accountability Office (GAO).
"During the past year, delays have occurred on every element and major subsystem schedule—especially with the cryocooler—leaving all at risk of negatively impacting the overall project schedule reserve if further delays occur," GAO notices.
