Diverse Organic Molecules on Mars from the First SAM TMAH Experiment

Supporting data for the first TMAH experiment on the Sample Analysis at Mars (SAM) instrument. The dataset, authored by Amy Williams, was last updated on April 23, 2026. It is available as a 20.4 MB XLSX file under a CC-BY-4.0 license.

Use Cases

• Analyze the diversity of organic molecules detected on Mars based on the experiment results.
• Validate and compare findings from the first SAM TMAH experiment.
• Support modeling of Martian soil and atmospheric chemistry based on the described organic compounds.

Strengths

• Data is directly associated with the first TMAH experiment on the SAM instrument, a key analytical tool on the Curiosity rover.
• Dataset is openly licensed (CC-BY-4.0) and was updated in 2026, suggesting recent curation.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
