Mars Panorama - Perseverance rover: Martian solar day 0454
Out of this World

Sol 0454Perseverance Now Selects its Own Targets to Zap

 

The panorama is made up of 101 individual Mastcam-Z images stitched together. The images were taken on Sol 454 (May 30, 2022).

 

Perseverance has continued into Hawksbill Gap, making remote sensing observations of small portions of outcropping rock layers in search of a good place to collect a sample. Since Perseverance is in the Shenandoah quadrangle, we are using target names from Shenandoah National Park. Some of the names this past week included “Bald_Face_Mountain,” “Little_Devil_Stairs,” “Sunset_Hill,” “Luck_Hollow,” and “Moody_Creek.” Perseverance logged nearly 400 meters of driving progress for the week of May 15-21, accumulating a total distance since landing of over 11.8 km as of Sol 446.

In another first, Perseverance selected two targets on Sol 442 and shot them with the SuperCam laser to determine their elemental compositions. Note that it was the rover itself that picked the targets, not the operations team. Normally, when the rover team picks the targets, the observations are not made until the following day. If Perseverance picks its own targets, it can shoot them right after a drive, many hours before the rover team back on Earth has time to receive and analyze the Navcam images from the rover’s new location and select targets. Having the SuperCam results right away can alert the team to unusual compositions in time to make decisions about further analyses before the rover moves on. The software package that enables this target selection is called Autonomous Exploration for Gathering Increased Science, or AEGIS, and was developed at JPL for previous rover missions and adapted for SuperCam on Perseverance. AEGIS requests Navcam images to be taken, and it then analyzes the images to find rocks and prioritize them for analysis based on size, brightness, and several other features. It subsequently initiates a sequence in which SuperCam fires its laser to determine the chemical makeup of one or two top priority targets selected from the Navcam images. AEGIS testing on Perseverance started in March by collecting SuperCam Remote Micro-Imager (RMI) images but not firing the laser. After tweaking several parameters on successive tests, the laser was used by AEGIS for the first time last week. The accompanying images show the rocks that were selected and shot. RMI images were taken after the laser shots to indicate where the laser fired. The Perseverance team plans to use AEGIS frequently from now on to provide more rapid data on the composition of rocks around the rover’s path.

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".
