This session will be a platform to present and discuss advances in seismic instrumentation and seismological methodology developed for Earth, Moon, Mars, Comet 67P etc. In preparation for new seismic missions endeavoring to deploy seismometers on Mars, asteroids, comets or even returning to the Moon, we want to initiate a session to present advances in building feasible, robust and low-power seismic instrumentation adequate for space, including new sensor concepts. Addressed issues may include data quality achievable by these instruments given their limitations in regards to frequency range, sensitivity, digital resolution or lifetime due to power, data storage and transfer.
Furthermore, we invite discussions of seismological methodology that can be adapted to the specific case of limited data availability and harsh conditions on extraterrestrial bodies: dealing with single-station setups, scarce networks, strong background noise, timing errors, unknown sources, the difficulties arising from robotic deployment, lacking imagery data and ineffective coupling between instrument and ground. Also of interest are the lessons to be learned from seismological experiments on ice in preparation for seismic exploration of the icy moons of the outer Solar System, and seismological experiments covering previously inaccessible regions on Earth, the oceans with e.g. the ocean-bottom seismometers and the floating hydrophones of the MERMAID project. Presentations are invited regarding knowledge and insights obtained from seismic data acquired by the Apollo active and passive seismic experiments, re-processing of the Apollo data with novel methodologies, conclusions drawn from the acoustic experiment SESAME onboard the Rosetta-lander Philae, as well as current endeavors to prepare for the seismic experiment installed on Mars during the InSight mission, seismic investigations of Earth analogues comparable to expected extraterrestrial environments, and studies undertaken in preparation for seismic missions to asteroids, comets, icy moons and other bodies.
This session aims to bring together the seismological community, interested in the methodological advance in seismic imaging of Earth, Moon, Mars, asteroids with scarce data availability or low-quality data. We welcome all contributions investigating the Earth's interior and extraterrestrial bodies with emphasis on development of methodology and instrumentation to deal with the extraordinary circumstances of extraterrestrial or Earth's ice- and ocean-based seismology.
