To show them the best web site, how to show them the best information from their friends is constantly trying to assess what makes the best Information Service for you. At the same time, universities for the last 20 years as weve moved more and more social Exchange Online have been moving to think about this as a social environment. This is the public square. So there are plenty of universities, plenty of researchers like myself who have come up with, you know, over the years come up with Research Projects that have to do with studying peoples experiences online. And in both those cases theres as much interest in figuring out what it is that people do as there is in people figuring out how to navigate those spaces. So theres both wanting to know what people do and people wanting to figure out the best way to find information. Theres two different threads of research that go on. Host how sophisticated is it getting . Guest um, what part . Host the research part. Guest you know, we have,
The orion and sls the vanguard of the program are the key to advancing these interests. I look forward to hearing from mr. Gerstenmaier and ms. Chaplain about the challenges and opportunities facing these important programs. I now recognize the Ranking Member from maryland. Its been a good morning to the witnesses. I want to join the chair man in congratulating nasa, lockheed, United Launch Alliance and the Contractor Team on conducting the exploration test of the orion capsule last week and i think that it was exciting and i know that around the country and around the world there were many of us working on Solution Division for the first time in a long time at the u. S. Space program that is very forwardlooking. They are below the orbits to test and verify the design can reduce technical risk and recover ability operations. Mr. Chairman, i belief that this Shows Americans the tangible progress is in fact being made on returning humans to exploration beyond earths neighborhood in the g
Step as nasa still has low confidence, 30 that it can meet the earlier date. Going forward, we have short and longterm concerns about nasas human Space Exploration programs. In the short term the programs are entering the most risky phases of development. There are still technical hurdles to overcome. Particularly with the orion spacecraft which is addressing challenges with the parachute system and heat shield among others. There is also considerable development and testing ahead for orion in terms of the human support systems. Meanwhile, sos is continuing to pursue the earlier launch dates of december 2017. While nasas urgency is understandable, the schedule for achieving the earlier date mostly with respect to the core stage is very aggressive. Theres little room to address problems. Moreover, it does not appear that orion and the ground system can achieve the earlier date. And the longterm we have concerns about the cost estimating for human Space Exploration programs. Nasas only p

Nasas only produce estimates for sos and ground system through the first flight test and orion through the second flight test. There is still Significant Development ahead for sos after the first flight and significan
