MARSIS: Mars Express Radar Sounding Data with Geometric Information

Scientific telemetry from the Mars Express MARSIS instrument, edited for duplicates and corruption, includes subsurface and ionosphere sounding data. Geometric information computed on ground provides spatial and temporal location for observations. Produced by NASA and last updated on March 13, 2026.

Use Cases

• Analyze subsurface geological structures based on radar sounding data.
• Study Mars ionospheric properties based on ionosphere sounding data.
• Map observation locations in space and time based on computed geometric information.
• Process and validate spacecraft telemetry based on edited data for duplicates and corruption.

Strengths

• Includes both subsurface and ionosphere sounding data, covering two scientific domains.
• Data has been edited for duplicated and corrupted packets, suggesting a level of quality control.
• Geometric information is computed on ground to locate observations.

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.
