MARS EXPRESS ASPERA-3 NPI: Neutral Particle Count Rates from 2003 to Mission End

Neutral Particle Imager (NPI) count rate data from the ASPERA-3 instrument aboard the Mars Express spacecraft. The data covers the period from the spacecraft's launch on June 2, 2003, through to the end of its mission. It was produced by the National Aeronautics and Space Administration.

Use Cases

• Analyzing neutral particle flux trends over time based on the count rate data
• Modeling the Martian atmospheric environment based on particle count measurements
• Correlating particle count rates with other Mars Express instrument data
• Studying long-term changes in Mars's space environment from 2003 onward

Strengths

• Data spans the entire mission lifetime from launch on June 2, 2003
• Provides measurements in a specific physical unit (counts/second)
• Originates from a well-defined instrument (ASPERA-3 Neutral Particle Imager)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
