It seems like just last week we were singing the praises of the oft-overlooked Mars Reconnaissance Orbiter (MRO). Over the weekend, the Mars satellite sporting one of the coolest cameras this side of the asteroid belt announced new data suggesting a surface formation on the Red Planet long held to be an impact crater may have been misinterpreted. The MRO's new analysis of the geology at the 57 mile-wide Mclaughlin Crater turned up evidence that the massive impact formation may have been a Martian lake at one point in its history -- and that the lake may have been fed by plentiful groundwater long ago in the planet's past.
Details are scant as to what exactly is happening in the video above, but it sounds like some blasting in a quarry created this huge explosion and tsunami-like wave in the lake above. Some commentors are already making the obligatory shouts of "fake!" of course. I don't know much about quarry blasting, but it looks pretty convincing to me. Internet, tell us what you think. Be forewarned: it's quite loud. (Liveleak via Gizmodo)
