Curiosity Blog, Sols 5029-5035: Back in the Lab

A black-and-white, downward-facing image from the Curiosity rover's Navigation Camera. Parts of the rover's metallic hardware frame the bottom and left edges of the image, including cylindrical mechanisms, structural joints, and a small checkered calibration target on the lower right. The rover casts a long, distinct diagonal shadow across the Martian surface below. The terrain consists of flat, light-colored bedrock covered in a prominent network of intersecting cracks. Patches of darker sand or soil and small, loose rock fragments are scattered across the surface, and a single, small circular drill hole or contact mark is clearly visible in the smooth bedrock near the center-right.

Earth planning date: Friday, Oct. 1, 2026

The majority of Curiosity plans involve mosaics from Mastcam and ChemCam, chemistry analyses from ChemCam and APXS, images from MAHLI and MARDI, and systematic measurements from REMS, RAD, and DAN. It is only when we stop to drill that we fully live up to our Mars Science Laboratory designation, using CheMin and SAM to analyze Martian rock. This was one such week, where our focus was wrapping up CheMin analysis of a sample from the “Basque Lakes” drill hole (pictured above), preparing SAM for its analysis, and analyzing the sample with the SAM tunable laser spectrometer (TLS). The CheMin data were key to SAM deciding to analyze the sample at all, and SAM will wait to receive the results from the TLS run (measurement of the volatiles present) to decide if they want to follow up with a separate mass spectrometry analysis next week. 

The laboratory activities require a significant portion of the daily power budget of the rover so the rest of the payload largely takes a back seat during drill campaigns, a worthy trade for CheMin and SAM’s valuable data. However, using the power that was available, we gathered data to contextualize our drill location and continued our systematic environmental monitoring. Mastcam acquired a 360-degree mosaic of our surroundings to build a full picture of the geologic setting of the sample. Its color and improved resolution relative to Navcam also guided subsequent science requests, such as more focused Mastcam imaging of structures near the workspace, and ChemCam RMI imaging of the “Cordillera” butte. Mastcam, coupled with Navcam, also planned a series of seven photometry observations spread across fixed times of day. These observations evaluate how the observed spectral characteristics of targets change as the Sun angle on them changes. They help us better interpret images from the rover and from cameras in orbit. ChemCam gathered more chemistry data from the variety of materials in the workspace, from the Basque Lakes drill hole interior, to sand ripples (“French Creek”) covering the bedrock, to loose gray clasts of unknown origin (“Wooley” and “Fireside”) sprinkled across the workspace. Our environmental monitoring activities included regular REMS, RAD, and DAN measurements and Navcam and Mastcam monitoring of dust loading in the atmosphere, cloud activity, and dust-devil activity.

A Journey to the Depths of Ancient Mars?

2026-10-06 00:48

A view of the Martian terrain showing reddish-brown, dusty ground littered with rocks of various sizes. In the foreground and midground, there is a cluster of large, angular rocks characterized by a highly textured, speckled pattern of white and dark grey. The surrounding surface is covered in smaller, rough pebbles and stones partially embedded in the sand. No sky or horizon is visible.

Perseverance captured the image using its Right Mastcam-Z camera on Aug. 30, 2026 (Sol 1965, or Martian day 1,965 of the Mars 2020 mission) at the local mean solar time of 11:42:55.

Sept. 29, 2026

After spending the last six months exploring “Lac de Charmes,” a region of ancient rock beyond Jezero crater’s western rim, Perseverance has stumbled upon a vast field of light-toned rocks peppering the Martian surface. 

Light-colored rocks are a strange sight on Mars, a planet dominated by dark-colored basaltic rocks. This many light-colored rocks in one place piqued the Science Team’s interest… what are they? How did they get here? 

To answer the first question, Perseverance has been investigating the composition and textures of these rocks. Data so far indicates that many of them are igneous rocks called gabbro, which are dominated by minerals rich in iron and magnesium. Such rocks typically form by slow cooling and crystallization of magma deep in the crust. 

So how did these deep fragments of Mars find their way to the surface? 

Perseverance has spent the last week trying to answer this question by investigating a patch of possible bedrock poking out between the light-toned boulders and loose regolith. 

Initial images suggest that the rock is made up of light- and dark-colored, angular fragments of rock, forming what geologists call a breccia. One possibility the team is investigating is that the light-toned boulders scattered across the hillside have eroded out of this breccia.

On the bottom right, a section of one of its treaded wheels rests on the dirt. On the left, the rover's robotic arm, featuring a complex instrument turret at its end, is extended toward the ground. The arm casts a long, distinct shadow over the reddish-brown, rocky sand. Parallel rover tracks are pressed into the soil, leading away toward a relatively flat, barren landscape that ends at a horizon of distant, low hills under a pale sky.
Perseverance deploys its arm mounted instruments to investigate a possible breccia outcrop at “Idubi.” The rover acquired this image of the area in front of it using its onboard Front Right Hazard Avoidance Camera A on Sept. 27, 2026 (Sol 1992, or Martian day 1,992 of the Mars 2020 mission) at the local mean solar time of 12:03:10.

Breccias often form through violent processes involving the fracturing and transport of rock to produce their angular shapes. Layers of breccia observed outside Jezero have previously been attributed to asteroid impacts on early Mars. Perhaps similar impacts (or the Jezero impact itself?) could be responsible for digging up these light-colored blocks.  

Only time (and of course, Perseverance), will tell.

NASA Testing Aims at Supercooled Large Droplet Aviation Safety

NASA Testing Aims at Supercooled Large Droplet Aviation Safety

NASA is leveraging its expertise and enhancing its test facilities to help address a rare but persistent aviation hazard: icing that occurs when aircraft encounter unusually large, very cold water droplets in clouds.  

The problem, known as “supercooled large droplet icing,” occurs when aircraft fly through clouds containing unusually large drops of water that are very cold but remain liquid. When a plane passes through those drops, they can rapidly freeze to surfaces that are not protected from ice buildup.  

With a series of tests in the Icing Research Tunnel at Glenn Research Center in Cleveland, NASA researchers are helping U.S. industry better understand the phenomenon.

Supercooled water is common in clouds – droplets can go below 32 degrees Farenheit but not freeze unless they encounter dust or other tiny particles around which they can crystalize. Aircraft are designed to encounter typical icing conditions where droplets range from 2 to 100 microns in diameter (for comparison, a human hair is about 70 microns wide). But in rarer cases, clouds can contain supercooled large drops up to 2,000 microns in diameter (if you’ve ever been caught in freezing rain, you’ve encountered these droplets at ground level). These much larger droplets can hit or splash to the aft of an aircraft, including areas behind conventional ice protection systems.  

The aviation industry relies on engineering tools to help design their aircraft. Current tools work well for typical clouds, but engineers have questions about how well they account for the physics of supercooled large drops. To help answer those questions, NASA is working to enhance the equipment it uses to generate and measure experimental clouds for testing in the Icing Research Tunnel.

NASA researchers have experimented with brand new probes that help calibrate the sizes of the drops in the clouds the tunnel produces. The probes can “see” drops larger than 45 microns and perform a real-time analysis of their sizes. NASA will compare these results, a laborious technique of post-processing droplet size image data from the tunnel. The results will be mated to results from a different probe that measures droplets smaller than 45 microns. With this, the complete droplet size spectrum is known. 

The test campaign marks an important milestone for the Subsonic Flight Demonstrator project, part of NASA’s Research and Technology Mission Directorate. Detailed analysis of the collected data continues, and NASA’s project team will share results with the broader aerospace community once complete.
