Weird ensembles, stone stripes, rockin’ grooves In January 2018, Opportunity rang in the New Year roving into a new ancient scene of
weird rock ensembles, stone stripes, bedrock-rich terrain and meandering roughs or
channels in Perseverance Valley. The valley, which cuts into the western rim of
Endeavour Crater is the site of the MER mission’s current research efforts. The rover’s
trek into the valley and her task of scientifically documenting her travels and findings
continued in February, through the rover’s 5000th sol or Martian day and beyond. "Five thousand sols after the start of our 90-sol mission," said MER Project Manager John Callas, of JPL, “this amazing rover is still showing us surprises on Mars.” NASA / JPL-Caltech / Cornell / ASU
