ODYSSEY MARIE: Martian Radiation Environment Data from 2001 to Present

MARIE aboard the 2001 Mars Odyssey spacecraft collected radiation data from April 2001 to the present. The instrument experienced a computer problem from August 2001 to March 2002 but has since collected data with only minor routine interruptions. This NASA experiment measures the Martian radiation environment, noting that particle flux can be directional during solar particle events.

Use Cases

• Modeling radiation exposure for crewed Mars missions based on the long-term Martian radiation measurements.
• Analyzing solar particle event impacts based on the description of directional particle flux during such events.
• Studying the isotropy of space radiation in the Martian environment based on the instrument's orientation and data collection method.

Strengths

• Data collection spans from April 2001 to the present, providing a long-term record.
• Managed by NASA, indicating authoritative collection and curation.
• Describes specific operational periods and interruptions, providing context for data gaps.

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.
