NASA’s upcoming James Webb Area Telescope (JWST) is unlikely to satisfy its launch date later this yr, in accordance with a brand new report by the USA Authorities Accountability Workplace (GAO), first documented by Ars Technica. The report, titled “James Webb Area Telescope: Technical Challenges Have Prompted Schedule Pressure and Could Enhance Prices,” particulars an investigation by the GAO into the newest standing of the troubled telescope.
The report appears at each the progress made on the JWST because the final report in March 2019, and the chance that the challenge will hit its launch date of November 2020. Within the former class, the challenge is doing effectively, with the report recognizing that the challenge has made “important progress” such because the testing of particular person components of the spacecraft and telescope, and dealing to combine these elements into one entire.
Concerning the potential of the challenge to make its launch date, nevertheless, the report is much less optimistic. There’s “solely a 12 % chance that this date might be achieved,” in accordance with the report, and delays appear possible as “NASA plans to reassess the launch date within the spring of 2020.”
The report describes the additional time constructed into the schedule of complicated tasks, known as “schedule reserve,” in addition to additional price range out there known as “value reserve.” These reserves are deliberate for on the idea that tasks as massive and bold as JWST usually require additional money and time for challenges which solely grow to be obvious as soon as work has already begun. The problem with JWST that the report appears most involved over is that the challenge has already used 76% of its schedule reserve, that means there’s little leeway out there ought to additional delays happen sooner or later.
As well as, the expenditure of this schedule reserve has meant that personal contractors, corresponding to these from Northrop Grumman, have been employed for prolonged intervals which has led to ballooning prices for the challenge.
Regardless of these points, the report acknowledged the work performed by NASA to answer worries over price range and time effectivity raised by the final report. It additionally acknowledges enhancements in efficiency by NASA contractors together with Northrop Grumman. It concluded that it will not make suggestions for the challenge, as NASA has already acted on earlier GAO suggestions.
We are going to wait and see if the JWST can hit its November launch date, however that’s wanting more and more unlikely.
