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).
Component: Panning and Zooming → Desktop
Product: Core → Tech Evangelism
Version: 51 Branch → Firefox 51
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.
