First off, awesome, I'm always looking for new datasets. So these complaints are fairly small, but currently stopping me from doing some things:
I can't see more than two items on this page: https://data.nasa.gov/data?&search=&type=datasets I'm just after a big list of datasets so I can skim through and find ones I'm intrigued by. Here's a screenshot: http://i.imgur.com/TtP630G.jpg (latest Chrome, mac)
The featured dataset links to a 404 page: https://open.nasa.gov/nasadatanauts/
Again, great to see the data out.
Edit - scratch the listing problem, it seems to be one of my extensions, either readability or pushbullet, breaking the site.
