New Horizons REX: Raw Radio Science Data from Jupiter Encounter

New Horizons spacecraft's Radio Science Experiment (REX) instrument captured raw data during its Jupiter flyby. This Version 2.0 dataset includes calibrations using known radio sources, Jupiter, cold sky measurements, operational readiness tests, and internal test patterns. The data was collected by NASA and last updated in March 2026.

Use Cases

• Calibrate radio science instruments based on known radio source and cold sky measurements described in the dataset.
• Analyze Jupiter's atmospheric properties using prime science radiometry observations from the encounter.
• Validate operational readiness for space missions using the included test patterns and operational readiness tests (ORTs).

Strengths

• Data originates from a NASA planetary science mission, the New Horizons spacecraft.
• Dataset is a Version 2.0 release, suggesting prior review and updates.
• Includes multiple calibration types: known radio sources, Jupiter, and cold sky measurements.

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.
