s.l.s., orion, commercial crew, and the james webb space telescope. the subcommittee will have a hearing next months about the j.w.s.t. program breach and north rum grumman's c.e.o. has agreed to tefment g.a.o.'s report identified significant cost and deadline problems with all four of these high interest programs. they are identified as having deteriorates cogs and schedule performance due to risky decisions involving technology. g.a.o. found that the commercial crew contractors continue to have significant delays in the test flight schedules. and nasa expects the orion program to exceed its cost aseline. g.a.o. assessed other nasa major projects this year as well. for example, the wide field infrared survey telescope remains a serious concern for congress. this committee has requested but not received the g.a.o. lifecycle cost estimate that was required by the fiscal year 2018 omnibus. congress has a responsibility to authorize and appropriate funding necessary to accomplish the task it directs nasa to carry out. but congress also has a responsibili

in the james webb program. a lot of things that had changed in a few years. it took way longer than anticipated. >> as we look forward, looking at requiring much more frequent updates on both cost and time line. >> it may be more of a rhetorical editorial comment. you wrote, including the regular use of continuing resolutions, the late year appropriations, results in endless multiple planning scenarios that result in whole schedules and accurate flight dates. is it then credible to say that congress plays a role in the problems that nasa has with budget and time line? >> yes, sir. i would say that. >> why not underpromise and overperform? that's what my children do with me. my job is to deliver the most science or exploration missions we can for the budget given. so we have taken an approach of having a portfolio of small, medium and large missions and an approach where we budget these missions at the 70% confidence level. we think that balance is the risk of projects in formulation and implementation against the opportunity costs of budgeting more than at th

for james webb and updated estimate may look at the current delays of done a few years ago. we find that some projects don't manage contractors well and react only after things become overwhelming. we've seen workmanship tears and they can have dramatic impact. lastly, nasa should take steps needed to look at cost growths that they don't overwhelm a portfolio. we did this when we undertook in review of the telescope before more costly phases begin. this should continue. in conclusion, we recommend recognize that nasa projects are complex. some growth is in evitable when you push the state. more can be done to limit risks that exasperate problems. this concludes my statement. i'm happy to answer questions. >> i now recognize mr. jersey for five minutes. >> mr. chairman, i'm pleased to have the opportunity to discuss program management accomplishments and challenges. nasa's focused on science and exploration. the agency has developed a process for program formulation. nasa's challenge is to develop and improve our program management capability to ensure efficiency and accounta

i think it's a healthy thing to do, and you see conditions change in the james webb program. there were a lot of things that had changed in a few years. the cryocooler, for example, took way longer to manufacture than anticipated and that would have been a good time to reassess their projects and they didn't do it. >> one of the things as we move forward is looking at requiring much more frequent updates. >> it may be more of a rhetorical, editorial comment, but you write, the current budgeting process including the regular use of continued resolution and late-year appropriations and threats of government shutdown result in endless multiple planning scenarios and hold schedules and predicting accurate flight dates and it's difficult when the budget is constantly in flux. is it credible to say that congress plays a role in the problems that nasa has with budget and time line? >> yes, sir, i would say that. you don't need to say any more. >> thank you for making that so clear. >> why not over -- over promise and underperform. i know that's what my children do with me. >> yeah.

that's what some of the folks ilding these big telescopes, telescopes to the james webb for example, they're going to be looking for come by nations of oxidizing and reduce things that might be evidence of life. so it's really fundamental, it's interesting. i sure hope you understood that. michelle: i understand we have another question from the media over audio. >> nancy atkinson, your line is open. >> hi. there was a similar announcement of detection of both methane and organic materials tpwhack 2014 also by the curiosity rover. how is this announcement different or how have you built on the find frgs 2014 for this detection? michelle: we were just talking about beforehand. jen, do you want to take that? jen: sure , in 2014 we reported the discovery of chlorinated molecule, carbon structures that have chlorine attach. it was a significant discovery, the first time we were able to confirm organic molecules on mars. they was first time. we had been looking for this for a very long time with the hope we would find it with the vikings instruments in 1976 and finally with curiosity in l

.>> i think we are all disappointed that the james webb cost of run missed deadlines. what programmatic changes would you make to the program to prevent this in light of this failure? >> could you answer that?>> i can tell you what we have done. >> the first is a series of actions we worked on. first of all, we completely restructured the organization, in order to be able to more clearly hold people accountable for getting to the integration desk program. that has allowed them to identify and resolve these issues in a timely manner. in order to minimize the impact of these issues. and we've also added staffing to the itt man at norfolk and we really, i would say, we strengthened the mission assurance function and personnel out there to deal with the workmanship and quality issues mentioned by miss chaplin and others. they tried to avoid the errors that have caused schedule delays, as was mentioned, a small error or problem, it's got a large effect on the program,>> in the 30 seconds remaining to have anything to add these comments?>> we've not done the significant over
