PVO VENUS MAG: Pioneer Venus Orbiter Magnetometer Averages

NASA's Pioneer Venus Orbiter collected magnetic field vectors around Venus, averaged over 24-second intervals. The data are provided in spacecraft coordinates, with the Z-axis orientation adjusted during the mission from alignment with Earth's ecliptic north pole to the pole of the Venus orbital plane. The dataset was last updated on March 13, 2026.

Use Cases

• Modeling Venus's magnetosphere based on averaged magnetic field vectors
• Analyzing solar wind interaction with Venus based on spacecraft coordinate data
• Studying mission operational changes based on the described spin axis reorientation

Strengths

• Data originates from NASA's Pioneer Venus Orbiter mission, a primary source for Venus exploration
• Vectors are averaged over 24 seconds on 12-second centers, providing a regular time series
• Dataset metadata includes a specific last update date of 2026-03-13

Limitations

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