Contamination analysis of Arctic ice samples as planetary field analogs and implications for future life-detection missions to Europa and Enceladus

Scientific Reports, 2022
Missions to detect extraterrestrial life are being designed to visit Europa and Enceladus in the next decades. The contact between the mission payload and the habitable subsurface of these satellites involves significant risk of forward contamination ...

The obliquity of Enceladus [PDF]

, 2015
The extraordinary activity at Enceladus' warm south pole indicates the presence of an internal global or local reservoir of liquid water beneath the surface. While Tyler (2009, 2011) has suggested that the geological activity and the large heat flow of Enceladus could result from tidal heating triggered by a large obliquity of at least 0.05{\deg}-0.1 ...

Enceladus Farm: Can plants grow with Enceladus' water? (Preliminary Report) [PDF]

arXiv, 2020
Enceladus is a saturnian satellite that should have liquid water inside of it (subsurface ocean). Measurements and experiments on water plume from Enceladus have revealed that Enceladus' ocean contains several salts such as NaCl. On the Earth, salt in soil has become a serious problem for agriculture, and importance of salt-tolerant plants are ...

Zehn Jahre Gaia‐Messungen: Die hochgenaue Kartierung des Himmels

Physik in unserer Zeit, EarlyView.
Das astrometrische Weltraumobservatorium Gaia der Europäischen Weltraumorganisation hat die astrometrische Forschung revolutioniert, indem es unter anderem präzise Positionen, Bewegungen und Entfernungen von fast zwei Milliarden Himmelsobjekten gemessen hat. Damit stellt es wertvolle Daten für fast alle Gebiete der Astrophysik bereit. Nach dem Ende der

Spatial Distribution of Ion Cyclotron Waves at Io

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Ion cyclotron waves at Io are important for understanding the complex interactions between Io and Jupiter's magnetosphere. In this study, we analyze the spatial distributions of ion cyclotron waves at Io using data from seven close flybys of Io—five by Galileo and two by Juno.

Gravity and Radio Science Investigation at the Moons of Uranus to Reveal Subsurface Oceans and Characterize Interior Structures

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract The prospect that the five major moons of Uranus could host subsurface oceans makes them high‐priority targets for future exploration. Different techniques can be used to search for deep oceans in these objects. Here, we focus on ocean detection and characterization from measurements of the moons' response to the gravitational tides and ...

The Distribution of Linear Virgae Across the Saturnian Moons

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract Linear virgae are long (10–100s km), narrow (<5 km), and bright features, first found on the surface of Dione. On Dione, linear virgae run parallel to the equator and are found in the low‐to‐mid latitudes. Linear virgae are likely formed by a process that involves the emplacement of materials from an exogenic Chronocentric (Saturn centric), or

The Potential for Organic Synthesis in the Ocean of Enceladus

The Astrophysical Journal
The Cassini spacecraft detected a soup of organics in the plume of Saturn’s moon Enceladus. Those compounds could provide building blocks for the potential emergence or sustenance of microbial life in Enceladus’ subsurface ocean. However, the sources and

Towards Determining Biosignature Retention in Icy World Plumes

Life, 2020
With the discovery of the persistent jets of water being ejected to space from Enceladus, an understanding of the effect of the space environment on potential organisms and biosignatures in them is necessary for planning life detection missions.

A Past Episode of Rapid Tidal Evolution of Enceladus?

The Planetary Science Journal, 2023
Saturn possesses a dynamically rich system containing numerous moons and impressive rings. Whether the rings of Saturn are much younger than the planet itself has been a long-standing open question; more recently a young age has been proposed for some ...
