This is a full sized model of the James Web Space Telescope. For scale its about the size of a tennis court. Easily the coolest thing at SxSW this week. The second was a video of the Space X rocket test showing a successful take-off and landing sequence. But I will save that for another day.
This telescope is the replacement for Hubble check out the site to learn more about it. http://www.jwst.nasa.gov/index.html
Some initial thoughts this represents what we as a civilization can do when we work together. This is an international endeavor, requiring us to create new technologies to make it happen. The long term impacts of the new technologies created will influence almost all facets of our life. Candidly, yes interactive is cool and changing how we work/connect everyday, however the things that NASA does is revolutionary.
One more thing, when its done it will sit 1 million miles from earth, it needs to work right the first time because we get one shot.
