A number of national holidays are taking place around the world this week and next, unofficially marking the start of summer for residents of the northern hemisphere. Holidays and extended weekends are seen as a time to catch up with family and friends, often centered around food and meaningful conversation. As a Canadian, my family, friends, and several of my Curiosity colleagues back in Canada may be doing exactly that for Victoria Day right now as I write today's blog from St. Louis Missouri, where I am currently engulfed by the steady and deafening drone of a double brood of both 13-year and 17-year periodical cicadas communicating with each other, something that hasn't happened since 1803.

While Curiosity may not know a holiday, it too is transitioning to summer, with perihelion only just recently passed and (southern) summer solstice a mere couple weeks ahead. Curiosity's operations are not only supported by a number of team members located all over the world, but also by multiple spacecraft orbiting Mars (as well as their respective teams). These orbital assets provide vital communication relays, primarily from Mars to Earth. 

It was a pretty standard Monday plan for our intrepid rover, with the science team electing to utilize the rover's contact science instruments before a drive in the first sol of a two-sol plan. Activities focused primarily on the "Pine Creek" target, located roughly in the center of the prominent bedrock block just above the aptly designed QR code on Curiosity's arm. Post-brush compositional analyses by APXS and ChemCam were complemented by images acquired by MAHLI and Mastcam. Prior to a ~30 m dogleg drive, Mastcam also acquired images of "Fairview Dome," "Pika Lake," "Whitebark Pass," and "Wilkerson Butte." A lengthy DAN passive activity also featured prominently on the first sol. The second sol of the plan included ChemCam AEGIS, a Navcam suprahorizon movie, and SAM cleaning activity following up its atmospheric analysis over the weekend.

A grayscale landscape photo from Mars, showing a broad, medium gray, rock-strewn plain in the foreground extending far into the distance, surrounded by several hills. The closest hill, in the lower right corner, rises up toward the side of the frame, and is darker than the floor below. A little farther out, on the left, a gentle slope rises from the low middle of the frame to middle of the left side; it’s about the same color as the valley floor, except for a band at its farthest edge, which darkens abruptly as if covered in shadow. The terrain appears softer than the ground below, more sandy than rocky. Beyond that along the same rising plane is a much lighter area, with scattered tiny peaks that are darker – looking like the top of a baked meringue pie. The channel floor runs between these hills, then appears to curve toward the right, behind the first hill and in front of the second. Finally, one other rounded peak appears above the horizon, behind these other two hills in the lower right of the frame, all of this below a light-gray sky filling more than half of the frame above.

A close-up color photo from the Martian surface shows a pale orange rocky outcropping, which looks on top like a sheet of coarse sandpaper, and on the side facing the camera like the feature is made from numerous, stacked thin layers, with undulating edges that make it look like a topographic map. Atop the feature are multiple plates of smooth stone in the same pale orange color, in different shapes, at different angles to each other, with a texture resembling clippings of thick, dense felt.
