MARS EXPRESS MRS: Radio Science Occultation Data from 2019

MARS EXPRESS Radio Science data from NASA's extended mission phase covers the period from 2019-01-01 to 2020-12-31. The dataset includes a specific occultation measurement event recorded on 2019-04 07 between 15:20:00 and 17:00:00 UTC. It was last updated on the Data.gov platform in March 2026.

Use Cases

• Modeling Martian atmospheric density profiles based on radio signal occultation measurements.
• Analyzing temporal changes in the Martian ionosphere based on the specified measurement event.
• Calibrating radio science instruments for planetary missions using the documented occultation data.

Strengths

• Data originates from NASA, a leading space agency, providing authoritative measurements.
• Covers a defined two-year extended mission phase from 2019-01-01 to 2020-12-31.
• Includes a precisely timestamped occultation event on 2019-04-07.

Limitations

• 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.
• Description metadata is limited; actual data quality requires manual inspection after download.
