PHX MARS TEGA 4: Thermal Evolved Gas Analyzer Data from the Phoenix Lander

NASA's Thermal Evolved Gas Analyzer (TEGA) dataset contains calibrated engineering, housekeeping, and scientific data from the 2007 Mars Phoenix Lander mission. The data was collected to analyze the composition of Martian soil and ice through thermal processes. The dataset was last updated on March 13, 2026.

Use Cases

• Analyzing Martian soil volatile content based on thermal evolved gas measurements.
• Calibrating spacecraft instrument models based on engineering and housekeeping data.
• Studying the thermal properties of the Martian surface near the Phoenix landing site.
• Validating scientific hypotheses about water ice and mineral composition from the described gas analysis.

Strengths

• Data is calibrated or converted, suggesting a processed state ready for analysis.
• Source is NASA, indicating authoritative collection and curation standards.
• Last update date of 2026-03-13 suggests ongoing metadata management.

Limitations

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