InSight HP3 Hammering: Reconstructed High-Rate Seismic Data from Mars

Mars data from the NASA InSight mission contains seismic signals recorded during the hammering of the HP3 heat probe. The original signals, sampled at 100 Hz, were subject to aliasing due to their broad frequency content. This dataset provides a reconstruction at 2000 Hz using a dedicated de-aliasing algorithm, enabling analysis of higher-frequency components.

Use Cases

• Analyzing high-frequency seismic wave propagation on Mars based on reconstructed 2000 Hz signals.
• Studying the mechanical interaction between the HP3 heat probe and the Martian regolith using hammering-induced vibrations.
• Developing and validating de-aliasing or signal processing algorithms for planetary seismology data.

Strengths

• Data is reconstructed to a higher sampling rate of 2000 Hz, mitigating aliasing issues present in the original 100 Hz recordings.
• Dataset is associated with a peer-reviewed scientific mission (NASA InSight) and a described de-aliasing algorithm.
• The archive is stated to be updated regularly with new data acquired on Mars, suggesting ongoing relevance.

Limitations

• Specific column names, row counts, and file sizes are not provided in the available metadata.
• The exact temporal coverage and update schedule are not specified.
• Data completeness relies on the success and operational timeline of the InSight lander's HP3 activity.
