GIOTTO MAGNETOMETER: Magnetic Field Data from Comet Halley Encounter

The GIOTTO MAGNETOMETER 8 SECOND DATA V1.0 dataset originates from the Giotto spacecraft mission by NASA. It contains magnetic field measurements from the encounter with Comet Halley, sampled at 28.24 vectors per second, using fluxgate sensors with multiple measuring ranges. The instrument had a total mass of 1360 g and consumed 820 mW of power.

Use Cases

• Modeling solar wind interaction with Comet Halley based on magnetic field measurements near the nucleus.
• Analyzing interplanetary magnetic field variations based on triaxial and biaxial fluxgate sensor data.
• Studying high-resolution magnetic field dynamics based on the 28.24 vectors per second sampling rate.
• Investigating instrument performance and data continuity based on memory modes designed to bridge telemetry gaps.

Strengths

• Data originates from a specific NASA mission with a clear scientific objective.
• Instrument specifications are detailed, including sensor types (triaxial and biaxial fluxgate), mass (1360 g), and power consumption (820 mW).
• Sampling rate is explicitly stated as 28.24 vectors per second.
• Memory modes allowed data collection during telemetry gaps of up to ten days.

Limitations

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