Reconstructed High-Rate SEIS Data from NASA InSight HP3 Hammering on Mars

Mars seismic data recorded by the NASA InSight lander's seismometer during the hammering activity of the HP3 heat probe. The data has been reconstructed from 100 Hz to 2000 Hz using a de-aliasing algorithm to capture the full frequency content of the signals. The dataset is provided by David Sollberger of ETH Zurich and is regularly updated with new data from Mars.

Use Cases

• Analyzing the frequency content of hammering-induced seismic waves based on the described de-aliasing process
• Studying Martian subsurface properties based on seismic signals generated by the HP3 heat probe
• Developing or validating seismic de-aliasing algorithms using the described reconstruction method
• Monitoring seismic activity on Mars over time based on the regular updates mentioned

Strengths

• Data is reconstructed to a high sampling rate of 2000 samples per second
• Dataset is updated regularly with new data acquired on Mars
• Accompanied by a detailed article describing the de-aliasing algorithm

Limitations

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