Sun-starved Opportunity in 'coma' waiting out the storm

14 June 2018

A massive Martian dust storm has prevented the solar-powered Opportunity rover from going about her daily work as robot field geologist. Dust blocking the sunlight is to blame, and the reason the Mars Explorer Rover is on hiatus. Much like a car needs gas to function, Opportunity needs the… Read More

Sol 2082: A New MAHLI Selfie

Sols 2061-2062: Time to feed CheMin

23 May 2018

After successfully drilling the “Duluth” target on Sol 2057 (as seen in the above Mastcam image), the science team is eager to find out what it’s made of.  As SOWG Chair today, it was exciting to plan the drop-off of material to CheMin and overnight CheMin analysis. … Read More

Sol 2063-2066: Sample drop-off testing

25 May 2018

Some of the Duluth drill sample was dropped into CheMin on Sol 2061, but not enough for a proper mineralogical analysis. So the top priority for today's plan is to again test the new drop-off procedure. Since the drill feed mechanism became unreliable over a year ago, drill samples can no… Read More
