NASA Considers Risking Rover on Dangerous Descent - Universe Today
NASA is currently making a difficult decision about whether to send its Opportunity rover down into Endurance Crater, which is 130 metres wide, and deep enough that the rover might not be able to climb back out. It's clear that there's some interesting science to be gathered in the crater, including more exposed rock surfaces. Opportunity will crawl around the rim of the crater and search for an ideal ramp that it could use to enter and exit safely.
