2015

2015 was a year of superlative achievements for the MER-B mission, starting off with summiting Cape Tribulation in January 2015, which was the highest elevation achieved yet on its mission. Then in March 2016 it accomplished the distance of a classic marathon. Also in March 2016 it achieved the steepest slope traverse (32 degree) yet of its mission, surpassing the slope it took on at Burns Cliff in 2004. MER-B was trying to reach a target on Knudsen Ridge, on the south side of Marathon Valley, which meant attempting a steep grade which can cause wheel slippage. Another effect of this angle was that sand and dust that had collected on the rover flowed in streaks over the back of the rover, such was the incline.
