This is a website bug. In http://nasaprospect.com/js/lib/hammer.custom.js they have this code:

p=Modernizr?Modernizr.touch:"ontouchstart"in window,Q=p?"touchstart":"mousedown"

and generally seem to be assuming that if touch is supported, then mouse is not. The same issue appears in Chrome (clicking on the up/down buttons with mouse doesn't work).

Looks like the site should handle both click and touch input, not either-or. 

Setting to needscontact.

I don't see this issue on Internet Explorer. On Surface Pro, with latest build of nightly(20160907030427)up and down buttons are not working either with touch or mouse click.

Yeah IE/Edge doesn't support touch events, so it will work fine for them.

Mike - does this still reproduce for you?

Yeah, the up and down buttons still don't work via mouse input -- but given the fact that this was "created by a group of student designers"... and won a site of the day award in 2013, I'm assuming it's unmaintained. 

You can also scroll with the scrollbar or with a trackpad if you have one. So not the end of the world.

Let's wontfix.
