Orbital geophysical investigations of Enceladus are critical to understanding its energy balance. We identified key science questions for the geophysical exploration of Enceladus, answering which would support future assessment of Enceladus astrobiological potential. Using a Bayesian framework, we explored how science requirements map to measurement requirements. We performed mission simulations to study the sensitivity of a single spacecraft and dual spacecraft configurations to static gravity and tidal Love numbers of Enceladus. We find that mapping Enceladus gravity field, improving the accuracy of the physical libration amplitude, and measuring Enceladus tidal response would provide critical constraints on the internal structure, and establish a framework for assessing Enceladus long-term habitability. This kind of investigation could be carried out as part of a life search mission at little additional resource requirements.
Summary of the long term data taking, related to one of the proposed next generation ground-based gravitational detectors location is presented here. Results of seismic and infrasound noise, electromagnetic attenuation and cosmic muon radiation measu
The Lunar Geophysical Network (LGN) mission is proposed to land on the Moon in 2030 and deploy packages at four locations to enable geophysical measurements for 6-10 years. Returning to the lunar surface with a long-lived geophysical network is a key
The five classical Uranian moons are possible ocean worlds that exhibit bizarre geologic landforms, hinting at recent surface-interior communication. However, Uranus classical moons, as well as its ring moons and irregular satellites, remain poorly u
Space radiation is well-known to pose serious issues to solid-state high-energy sensors. Therefore, radiation models play a key role in the preventive assessment of the radiation damage, duty cycles, performance and lifetimes of detectors. In the con
The icy moons are in the focus of the exploration plans of the leading space agencies because of the indications of water-based life and geological activity observed in a number of these objects. In particular, the presence of geyser-like jets of wat
