Today's VIS image shows a section of Mamers Valles. Mamer Valles is nearly 1000 km long (600 miles). It originates near Cerulli Crater in northern Arabia Terra, and after a short section near the crater where flow is to the south, flows northward to empty in Deuteronilus Mensae. The section of the channel in this image is part of the southward flowing part of the system. The steep walls of Mamers Valles can reach heights of 1200 m (4000 feet).
This martian scene spans 19 x 68 kilometers (12 x 42 miles). To see where on Mars this area lies, and to download high-resolution versions of the image go to themis.asu.edu/zoom-20220701a

This self-portrait of NASA's Mars Exploration Rover Opportunity shows effects of wind events that had cleaned much of the accumulated dust off the rover's solar panels. It combines multiple frames taken by Opportunity's panoramic camera (Pancam) through three different color filters from March 22 to March 24, 2014, the 3,611th through 3,613th Martian days, or sols, of Opportunity's work on Mars.
With the cleaner arrays and lengthening winter days, Opportunity's solar arrays were generating more than 620 watt-hours per day in mid-April 2014, compared to less than 375 watt-hours per day in January 2014. This image is presented as a vertical projection in approximately true color. The mast on which the Pancam is mounted does not appear in the image, though its shadow does.
The moment I got to the top of this horrible staircase, I clearly heard a voice from the basement below say "Oh yeah, raw meat." This isn't particularly what ones wants to hear when stuck inside a pretty disturbing derelict building. I reasoned that the voice almost certainly had wafted in from the street outside. Alternatively, if someone was coming up the stairs, I had the advantage of the high ground :-|.
I didn't actually take this shot right then -- I did it when I was coming back down through the building (but I didn't choose to go out this way).

A promontory nicknamed Cape Verde can be seen jutting out from the walls of Victoria Crater in this false-color image taken by the panoramic camera on NASA's Mars Exploration Rover Opportunity. The rover took this picture on Martian day, or sol, 1329 (Oct. 20, 2007), more than a month after it began descending down the crater walls -- and just 9 sols shy of its second Martian birthday on sol 1338 (Oct. 29, 2007). Opportunity landed on the Red Planet on Jan. 25, 2004. That's nearly four years ago on Earth, but only two on Mars because Mars takes longer to travel around the sun than Earth. One Martian year equals 687 Earth days.

Arctic Exploration
ca. 1850-1875
Captain Henry Kellet left tins of roast beef and ox cheek soup in his Dealy Island cache in 1853; Captain Francis McClintock left the boots and saw behind at Melville Island in 1852-53; and Captain George Nares’ crew used the decorated dinner plate during his 1875 search for the North Pole.
