Curiosity advances Basque Lakes sample analysis on Mars
Imaging, chemistry, and environmental monitoring continued on 2026-10-01.
- On October 1, 2026, CheMin analysis of the Basque Lakes drill-hole sample was nearing completion.
- SAM's tunable laser spectrometer was analyzing the same sample, and CheMin results guided SAM's next step.
- Mastcam captured a 360-degree mosaic and scheduled seven photometry observations across the day.
- ChemCam, APXS, MAHLI, MARDI, REMS, RAD, and DAN continued chemistry, imaging, and environmental monitoring.
- Laboratory work consumes a large share of the rover's daily power budget.
What happened
The Curiosity rover conducted science operations on Mars on 2026-10-01. It was completing CheMin analysis of material from the Basque Lakes drill hole while SAM prepared to analyze the same sample.
What we know
The payload work included Mastcam and ChemCam mosaics, ChemCam and APXS chemistry measurements, MAHLI and MARDI images, and regular REMS, RAD, and DAN observations.
CheMin and SAM were used to examine Martian rock. Curiosity was closing out CheMin analysis of a sample from the Basque Lakes drill hole, SAM had been prepared for the sample, and SAM's tunable laser spectrometer was analyzing it. CheMin results were central to SAM's decision to proceed.
These laboratory activities consume a significant part of the rover's daily power budget.
Mastcam obtained a 360-degree mosaic of the rover's surroundings and made targeted images of structures near the workspace. The camera supplies color and better resolution than Navcam.
Mastcam planned seven photometry observations at set times of day to see how targets' spectral characteristics change as sunlight angle changes.
ChemCam's RMI imaged the Cordillera butte, and ChemCam collected additional chemistry information from varied materials in the workspace.
REMS, RAD, and DAN kept up regular environmental monitoring. Navcam and Mastcam monitored atmospheric dust loading, clouds, and dust-devil activity.
The update also noted the inside of the Basque Lakes drill hole, sand ripples covering bedrock at French Creek, and loose gray fragments whose origin is unknown at Wooley and Fireside.
Why it matters
For readers tracking the lunar industry, the update shows how power limits shape robotic surface science: laboratory work takes a large share of daily energy, while cameras and sensors keep up imaging and environmental monitoring.
It also shows sample selection driven by instrument data: CheMin results influenced SAM's decision to analyze the sample, and tunable laser spectrometer results will guide any separate mass spectrometry follow-up.
What's next
SAM will wait for results from its tunable laser spectrometer before deciding whether to conduct a separate mass spectrometry analysis of the sample.
