As of sol 575 Perseverance has travled over 12 km and Ingenuity has made 33 flights. Currently Persverance is collecting samples at the base of the Jezero Crater delta. I have been field geologic mapping the traverse out to 30 m from the rover during the entire delta campaign and some of the maps are shown in the following. The delta is a classic Earth-style "Gilbert delta" and the layers of sediment arre being examined carfefully for potential biogenic materials, cored, and stired on the rover for delivery to a caching site. Shortly we will collect a couple of more samples and then drive to the sample caching site where the Mars Sample Return lander will land some time after 2030, collect the samples from the cache, and return them to Earth.

Sol  4039 - Two Week Period of Solar Conjunction Begins

Since my last post Opportunity has successfully driven from the summit of Cape Tribulation (the name we gave the highest point on the rim). The goal has been to arrive at a deep notch or valley ("Marathon Valley") in the crater rim by about March 15. Remote sensing from the orbiting Mars Reconnaissance Obiter (MRO) has shown that some spectacular exposures of weathered and altered minerals should be exposed there. That is always a clue that it is geologically very interesting in more than just minerals and chemistry.

Opportunity just finished up the super crater overview panorama, pulled away from the summit (here at -1380 m) and we are on our way to Marathon Valley! It's all downhill (about 70 m down in elevation) from here.

Above is a map showing the drive and 1 m contours. Note the small impact crater a few meters to the SW which is visible in the Navcam posted below.

Opportunity made it to the summit!! The view is spectacular. From here we can see all the way to the other side of the crater, we can see the rim looking north along the path to this location, and we can see far to the south, including another large impact crater that lies 10 km or so south of Endeavour.

We will be doing a Pancam color summit panorama over the next few days before moving on. Here is the Navcam pan from this location.

Despite memory problems, Opportunity is forging ahead and is now approaching the highest point on the rim of Endeavour crater. The view is beginning to be spectacular.

Above is part of the Navcam view taken on sol 3893. The view looks across the deck of the rover toward the summit which is now just a few meters away. ON the left you can see the flloor of Endeavour crater and the far rim 12 miles away.

Opportunity is continuing its drives along the rim of the 22-km diameter impact crater Endeavour. In the next few drives it will be at or near the highest peak along the rim, Cape Tribulation summit. At that point Opportunity will be as high in elevation on Mars as it will ever be. The panoramic view from that summit should be awesome. Mid summer is only a few sols away.   

Opportunity finished up its work on Wdowiak Ridge and has now continued southward along the rim of Endeavour crater. The ultimate goal is a large valley cutting through the crater rim that we have informally named “Marathon Valley”.
