Habitat-OASIS – Habitability of Oceans and Aqueous Systems on Icy Satellites

Habitat-OASIS addresses the question of habitability of the outer solar system by looking at spacecraft data and preparing for future space missions using novel approaches. The classical view held that for a planet or moon to be habitable requires liquid water at or near its surface. This view has been challenged by the discovery of numerous subsurface oceans below the icy crusts of moons orbiting Jupiter and Saturn. In particular, the cryo-volcanic moons Enceladus and Europa, orbiting Saturn and Jupiter respectively, are considered to have the largest astrobiological potential. On these two moons, the ocean floor is in contact with a rocky core and there are indications for hydrothermal activity - hot water flowing out from the rocky sea floor into the ocean. On Earth, these kinds of hydrothermal vents are places where life developed independently of sunlight.

The project Habitat-OASIS includes the following aspects:

1 Exploring Enceladus’ Subsurface Organic Material

The compositional analysis of organic material emerging from the subsurface ocean of Enceladus is vital for constraining the astrobiological potential of Saturn’s small icy moon. Cryovolcanically active, Enceladus ejects a plume of water vapour and ice particles from fractures in the icy crust of its south polar terrain. Grains emitted fast enough can leave the region dominated by the moon’s gravity, and enter Saturn’s diffuse E ring, itself formed largely by these plume particles. The mass spectrometer of the Cosmic Dust Analyzer (CDA) aboard the Cassini spacecraft analysed ice grains in both the plume and the E ring between 2004 and 2017. Over 200,000 mass spectra were recorded during this period. Our investigation of the wealth of spectra returned by Cassini’s CDA is ongoing, with analysis of flight data supported by further laboratory analogue experiments. Characterizing signatures from organic material to enhance further our knowledge about the organic inventory and also to further explore the astrobiological potential of the moon.

2 Inorganics in Ocean Worlds – a Rocky Interaction with Water

When water interacts with rocks and minerals, it can leach inorganic compounds into solution. However, unlike on the Earth, where rain water running off the land is primarily responsible for the salinity of the sea, on ocean worlds such as Enceladus and Europa this is not the case. Instead, interaction between a subsurface ocean and the rocky core it surrounds, produces a salt-rich, briny, ocean within the bodies. To predict the appearance of such inorganic signatures, and understand the concentrations within the grains at which they can be detected, a comprehensive programme of analogue laboratory experiments is underway within the group. The data from these analogue experiments will be used to predict, and subsequently interpret, the likely results from future missions to ocean worlds, such as those from the Surface Dust Mass Analyzer (SUDA) instrument onboard the upcoming Europa Clipper mission to Jupiter’s moon Europa.

3 Laboratory Facility to Simulate Impacts of Hypervelocity Ice Grains from Ocean Worlds in Space

Simulating hypervelocity dust/ice grain impacts onto space detectors is crucial for our ongoing and future research projects. During an impact, a fraction of the dust/ice particle is converted into elemental and molecular ions (a process known as impact ionization) that can then be analyzed by mass spectrometry. This is the principle method we use in Habitat-OASIS to explore the subsurface oceans of Enceladus with the Cosmic Dust Analyzer (CDA) aboard Cassini and the Surface Dust Analyzer (SUDA) on Europa Clipper. Laboratory analogue experiments are an essential element of the interpretation of impact ionization mass spectra recorded in space.

4 Spectral Reference Library for Future Space Missions

With the first laboratory spectra recorded in 2012, the facility has been running for over 7 years, generating approximately 10.000 mass spectra. The huge range of mass spectra encompasses different analogue materials for icy grains as well as variations in instrument parameters that can be adjusted individually for each measurement. To facilitate the easy searching, access and extraction of spectra from this large and growing library, an internally accessible database (spectral reference library) containing all recorded spectra has been created.

  

In addition to Habitat-OASIS, Prof. Postberg is involved in the following projects:

Composition of Saturn’s Rings and Mineral Dust at Saturn

The dynamical and compositional characterization of Saturn's ring system is a prime goal of our dust detector, Cosmic Dust Analyzer (CDA), on-board the Cassini spacecraft. In the years 2016 and 2017, during the Grand Finale, Cassini has frequently dived through the small gap between the inner edge of the ring system and Saturn's upper atmosphere, allowing for compositional in situ measurements of debris particles emitted from the main rings. In collaboration with ESA we started a project to explore exogenic mineral dust that CDA detects and that does not stem from Saturn’s ring system. The goal is to perform the complete mapping of the composition of these non-icy micro-meteoroids within the Saturnian system, and to relate the compositional information to the grains dynamics, such as to constrain the properties of their parent bodies.

Composition of Interplanetary and Interstellar Dust in our Solar System

Interstellar dust particles can be analyzed in situ from a spacecraft or can be captured and brought back to Earth by a sample-return mission. Prof. Frank Postberg is Co-Investigator of the Destiny+ Dust Analyzer (DDA) experiment on-board the Destiny+ mission that is prepared for launch in 2024. Destiny+ was designed by JAXA to acquire the compact deep space explorer technology, fly-by observation of a meteor shower parent body, and in situ analysis of interplanetary dust. It will conduct flyby exploration of the asteroid 3200 Phaethon, which is well known as a parent body of a meteor shower.
