Mars Panorama - Curiosity rover: Martian solar day 2991
Out of this World

Sol 2991New Year's Resolution


The images for panorama obtained by the rover's 34-millimeter Mast Camera. The mosaic, which stretches about 30,000 pixels width, includes 123 images taken on Sol 2991 (January 3, 2021).


Here on Earth, people often use the start of a new year as an opportunity to adopt new resolutions for themselves. In planetary exploration, we often talk about a different kind of resolution, namely the spatial resolution of the cameras carried by a spacecraft. The Curiosity rover has a large suite of cameras with a range of spatial resolutions, one of which is the Mars Hand Lens Imager (MAHLI) camera. Located at the end of the rover’s robotic arm, MAHLI can be placed in close proximity to the surface to acquire incredibly high-resolution images of the grains within loose soil and rocks. And in the rover’s first plan of 2021, MAHLI’s imaging capabilities took center stage. Right before the holiday break, Curiosity had been making her way across rubbly terrain towards a set of large sand ripples located within the Sands of Forvie. One of our primary motivations for visiting these ripples was to acquire high-resolution MAHLI images of the sand comprising them. When wind blows sand around, it naturally sorts it based on properties such as particle size, so close-up images of sand grains on different parts of a ripple can provide a means to study natural sorting processes and the winds controlling them. As seen in the image above (acquired at our current location on Sol 2989), MAHLI is able to resolve the size, shape, and color of individual grains of sand that are no larger than those you would find at a beach here on Earth. As today provided our first opportunity to study the Sands of Forvie ripples after our New Year’s scuff, a major focus of our planning was to obtain a preliminary set of MAHLI images of the crest and trough of a prominent ripple in our workspace. These images will allow the team to plan a second set of even higher-resolution MAHLI images tomorrow. Other scientific measurements planned today included an APXS measurement to accompany MAHLI images of the ripple trough, ChemCam observations on sand targets “Carsaig East” and “Carsaig Arches," and Mastcam “change detection” images for tracking sand motion. Special morning and evening change detection images were also scheduled to help us better constrain the timing and direction of the winds responsible for shaping the Sands of Forvie ripples. A Mastcam stereo mosaic and Mastcam multispectral observation will provide additional data on the ripples in our immediate workspace. DAN and REMS measurements, as well as a small set of Navcam and Mastcam observations will also allow us to probe the current environmental conditions. The team is excited to be ringing in the new year at this interesting – and sandy – spot, and we are looking forward to exploring many more new terrains in 2021 as we continue our traverse up Mount Sharp.

More About Out of this World

The planet Earth has proven to be too limiting for our awesome community of panorama photographers. We're getting an increasing number of submissions that depict locations either not on Earth (like Mars, the Moon, and Outer Space in general) or do not realistically represent a geographic location on Earth (either because they have too many special effects or are computer generated) and hence don't strictly qualify for our Panoramic World project.But many of these panoramas are extremely beautiful or popular of both.So, in order to accommodate our esteemed photographers and the huge audience that they attract to 360Cities with their panoramas, we've created a new section (we call it an "area") called "Out of this World" for panoramas like these.Don't let the fact that these panoramas are being placed at the Earth's South Pole fool you - we had to put them somewhere in order not to interfere with our Panoramic World.Welcome aboard on a journey "Out of this World".
