NASA’s Opportunity rover has been busy examining the entranceway to Perseverance Valley, a long, shallow gully-like channel on the rim on Endeavour Crater which was likely created by flowing water millions or billions of years ago. This feature has been a major target of interest for mission scientists since, if confirmed, this would be the first such gully seen up close by any rover. A new panoramic image just released shows the view on the crater rim just above the valley itself, which includes a possible “spillway” where water once flowed over the rim and into the crater down below.
For about the past 30 months, the Opportunity rover has been exploring Cape Tribulation on Mars, a towering ridge on the rim of Endeavour crater. Now, Opportunity has finally left that location, to continue its journey southward down the western side of the crater rim. The views have been scenic from the top of Cape Tribulation, but now it is time to move on, and head to the next major target, an ancient gully not too far to the south-east, also on the crater rim. This gully is thought to have been carved by running water millions or billions of years ago, so scientists are very interested in examining it up close, and the rover is now almost there.
