Sizzling New Evidence on Martian Streaks

20 December 2017

In this exciting press release, USGS scientist, Colin Dundas, provides evidence that seasonal dark streaks on warm Martian slopes, called recurring slope lineae (RSL), are something other than salty water, as scientists originally thought and hoped for. Colin is also the lead author in the Nature GeoScience publication which contain the gritty details of these magnificent findings. I can hardly wait until you discover what Colin had to say.
