Venµs is a research satellite, and a rather agile one (at least for a microsatellite). It enables us to make experiments useful for users like us who like to study physics of optical measurements (which is an allowed perversion, as fas as I know). We have started last year to acquire multi-angular observation, under 3 […]

S. P. Hicks (@seismo_steve) wrote for Nature Geoscience a nice piece « Geoscience analysis on Twitter » where he shares his experience on using Twitter for the real time analysis of geohazards. Actively using Twitter for science may be perceived by some as a significant time-sink — the demands on individual researchers and their institutions at times […]
