At INAF IAPS we have two positions open described below.

Monitoring the alteration of drill cores from Martian subsurface sampling

Context

Accurately determining the composition of Martian subsurface materials is essential for evaluating Mars’ geological history and habitability potential. Although the ExoMars Rosalind Franklin rover’s drill cores are protected from direct environmental exposure, they may still experience alteration due to frictional heating during drilling and subsequent crushing processes, potentially affecting scientific analysis.

Scientific Challenges

By comparing spectroscopic data from Ma_Miss (at the drill tip) with those collected on crushed samples by MicrOmega and RLS, researchers can assess alteration effects from sample handling and develop strategies to reduce impact. However, these collaborative practices have yet to be systematically tested.

Research Objectives

Identify potential mineral dehydration, alteration and structural changes during drilling and crushing of the sampled core; Develop a protocol for detecting dehydration and sample alteration; Integrate datasets from ERF spectrometers to improve subsurface geological interpretations.

Impact

Develop advanced methodologies for estimating mineral abundance via NIR spectroscopy Develop automated protocols for cross-comparison of complementary color data and spectroscopic data (improve accuracy in detecting sample alterations); Enhance the scientific return of the ExoMars mission, serving as a reference for future drilling missions (maximize insights gained from in-situ analysis); Provide a holistic understanding of stability and alteration dynamics of Martian subsurface materials (deepen knowledge of Martian subsurface conditions and processes).

Hiring institution The candidate will be hired by the Sapienza University of Rome (LSU, Italy), while the Istituto Nazionale di Astrofisica (INAF-Rome) will act as the hosting institute.

Developing Spectral Analysis Tools for Trace Organic Detection and Biosignature recognition in Geological Mixtures

Context

The detection of organic biosignatures on Mars is closely tied to the mineral composition of samples, with phyllosilicates being key due to their ability to adsorb and protect organics from UV radiation. Formed through prolonged water-rock interactions, phyllosilicates suggest past habitable conditions, making these regions priority targets for astrobiology missions.

Scientific Challenges

Despite heavy reliance on spectroscopic instruments, few studies have assessed their capacity to detect trace organics within complex Martian-like mineral mixtures. Additionally, the impact of UV-induced alteration on organic signatures and differentiation between biosignatures and abiotic molecules remains poorly understood.

Research Objectives

Define spectrometer detection limits for trace organics in complex mineral matrices; Examine phyllosilicates’ role in preserving organics under harsh conditions; and Develop cooperative-science protocols to reliably differentiate altered biosignatures from abiotic signals.

Impact

Develop advanced methodologies for estimating mineral and organic abundance via NIR spectroscopy (improve precision in identifying key Martian minerals); Develop advanced spectral analysis tools for detecting trace organics in Martian mixtures (improve biosignature identification accuracy); Establish protocols for distinguishing organic biosignatures from abiotic compounds (enhance reliability in biosignature detection). Strengthen Ma_Miss, RLS, and MicrOmega (synergy with DC15) capabilities and provide insights from comparisons with instrument used in previous missions (optimize combined strategies for future missions).
