MER 1 APXS EDR: Mars Exploration Rover Alpha Particle X-Ray Spectrometer Data

Mars Exploration Rover mission operations data from the Alpha Particle X-Ray Spectrometer (APXS) instrument. The archive contains original Experiment Data Record (EDR) products and ancillary files used during mission operations, with documentation conforming to the Planetary Data System (PDS) Standards, Version 3.6. The data is provided by the National Aeronautics and Space Administration.

Use Cases

• Analyze Martian surface elemental composition based on APXS spectrometer measurements.
• Validate instrument calibration and operational parameters based on the ancillary files and PDS labels.
• Study mission operations data workflows based on the original products used during the Mars Exploration Rover project.

Strengths

• Data conforms to the documented Planetary Data System (PDS) Standards, Version 3.6.
• Contains the original products used during Mars Exploration Rover mission operations.
• Each product has a detached PDS label describing file structure and instrument parameters.

Limitations

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