Mountain glaciers around the globe are retreating rapidly, but the exact mechanisms causing the retreat are not well understood. Is warming of the atmosphere the key driver? What are the roles of changes in surface albedo due to contaminants and snow optical grain size and surface roughness? Improved understanding of the response of mountain glaciers to global and environmental change is key to answering...

Spaceborne persistent multi-angle imaging allows staring at selected targets during an orbit pass. From its vantage point on the International Space Station (ISS) a persistent Earth imaging telescope would provide hundreds of high-resolution images simultaneously. Observations could be in visible and SWIR bands as it stares at a scene of interest. These images provide rich multi-angle stereo views...
