MARS EXPRESS MRS: Radio Science Occultation Data from 2021-2022

Mars Express Radio Science data collected by NASA during the extended mission phase from 2021-01-01 to 2022-12-31. The specific occultation measurement covers the time interval 2021-01-17T13:46:12.399 to 2021-01-17T14:08:20.649. This dataset is part of the MARS MRS 1/2/3 extended mission series.

Use Cases

• Analyzing Martian atmospheric density profiles based on radio signal occultation measurements.
• Studying temporal changes in the Martian ionosphere based on the 2021-2022 mission data.
• Validating atmospheric models for Mars using precise radio science observations.
• Investigating signal propagation effects through the Martian atmosphere during specific occultation events.

Strengths

• Data originates from a defined NASA mission (Mars Express) and instrument (Radio Science).
• Covers a specific two-year extended mission period from 2021-01-01 to 2022-12-31.
• Provides a precise timestamp for a sample occultation event (2021-01-17T13:46:12.399 to 2021-01-17T14:08:20.649).

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.
• The license is listed as 'other-license-specified', requiring careful review before use.
