MARS EXPRESS ASPERA-3: Neutral Particle Imager Count Rates for 2017-2018

NASA's MARS EXPRESS ASPERA-3 Neutral Particle Imager (NPI) data set contains particle count rates for the sixth mission extension from January 1, 2017 to December 31, 2018. The data are provided in units of counts per second. The dataset was last updated on March 13, —.

Use Cases

• Analyzing temporal trends in neutral particle flux around Mars based on count rate data.
• Modeling the Martian exosphere and atmospheric escape based on particle measurements.
• Correlating neutral particle activity with other spacecraft instrument data from the same time period.

Strengths

• Data originates from NASA's Mars Express mission, a credible source.
• Covers a defined two-year time range from 2017 to 2018.
• Data is provided in a specific physical unit (counts per second).

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.
