PHX MARS TEGA 2 SCEDR: Raw Mars Phoenix Lander Gas Analyzer Data

Raw, uncalibrated engineering, housekeeping, and scientific data collected from the Thermal Evolved Gas Analyzer (TEGA) aboard the 2007 Mars Phoenix Lander. The dataset is provided by the National Aeronautics and Space Administration (NASA) and was last updated in March 2026.

Use Cases

• Analyze Martian soil volatile content based on thermal evolved gas measurements.
• Monitor spacecraft instrument health and performance based on engineering and housekeeping data.
• Calibrate raw scientific instrument readings for downstream analysis.

Strengths

• Data originates from the authoritative NASA Mars Phoenix mission.
• Includes raw, uncalibrated scientific and engineering data streams for transparency.

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.
