MARIE: Martian Radiation Environment Data from 2001 Mars Odyssey

The 2001 Mars Odyssey spacecraft collected radiation data from Mars orbit starting in late April 2001. NASA's MARIE instrument measured the Martian radiation environment, with data collection interrupted by a computer problem in August 2001 before resuming in March 2002. Data were collected intermittently during the cruise phase and nearly continuously during the orbital phase, with minor routine interruptions.

Use Cases

• Modeling the Martian radiation environment based on particle flux measurements.
• Studying solar particle event directionality based on the description of non-isotropic radiation.
• Analyzing spacecraft instrument performance and data continuity based on the described operational timeline.

Strengths

• Data collected from a dedicated NASA instrument aboard the 2001 Mars Odyssey spacecraft.
• Describes a specific operational timeline, including launch on April 7, 2001, and arrival at Mars on October 24, 2001.
• Data collection occurred from 2001 to the present without major interruption after March 2002.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats are JPEG and HTML, which may not be standard for quantitative radiation data analysis.
