    Exploration of Planetary Hyperspectral Images with Unsupervised Spectral Unmixing: A Case Study of Planet Mars 
    Liu, Jun; Luo, Bin; Douté, Sylvain; Chanussot, Jocelyn (MDPI AG, 2018-05-10)
    We propose to replace traditional spectral index methods by unsupervised spectral unmixing methods for the exploration of large datasets of planetary hyperspectral images. The main goal of this article is to test the ability of these analysis techniques ...

    Microbial Markers Profile in Anaerobic Mars Analogue Environments Using the LDChip (Life Detector Chip) Antibody Microarray Core of the SOLID (Signs of Life Detector) Platform 
    García-Descalzo, Laura; Parro, Victorino; García-Villadangos, Miriam; Cockell, Charles S.; Moissl-Eichinger, Christine; Perras, Alex; Rettberg, Petra; Beblo-Vranesevic, Kristina; Bohmeier, Maria; Rabbow, Elke; Westall, Frances; Gaboyer, Frederik; Amils, Ricardo; Malki, Moustafa; Marteinsson, Viggó; Vannier, Pauline; Ehrenfreund, Pascale; Monaghan, Euan; Riedo, Andreas; Cabezas, Patricia; Walter, Nicolas; Gómez, Felipe Gómez (MDPI AG, 2019-09-18)
    One of the main objectives for astrobiology is to unravel and explore the habitability of environments beyond Earth, paying special attention to Mars. If the combined environmental stress factors on Mars are compatible with life or if they were less ...

    Molards as an indicator of permafrost degradation and landslide processes 
    Morino, Costanza; Conway, Susan J.; Saemundsson, Thorsteinn; Helgason, Jón Kristinn; Hillier, John; Butcher, Frances E.G.; Balme, Matthew R.; Jordan, Colm; Argles, Tom (Elsevier BV, 2019-06-15)
    Molards have been defined in the past as conical mounds of debris that can form part of a landslide's deposits. We present the first conclusive evidence that molards in permafrost terrains are cones of loose debris that result from thawing of frozen ...

    Sample Collection and Return from Mars : Optimising Sample Collection Based on the Microbial Ecology of Terrestrial Volcanic Environments 
    Cockell, Charles S.; McMahon, Sean; Lim, Darlene S.S.; Rummel, John; Stevens, Adam; Hughes, Scott S.; Kobs Nawotniak, Shannon E.; Brady, Allyson L.; Marteinsson, Viggo; Martin-Torres, Javier; Zorzano, Maria Paz; Harrison, Jesse (2019-10-01)
    With no large-scale granitic continental crust, all environments on Mars are fundamentally derived from basaltic sources or, in the case of environments such as ices, evaporitic, and sedimentary deposits, influenced by the composition of the volcanic ...

    A study in blue : Secondary copper-rich minerals and their associated bacterial diversity in Icelandic lava tubes 
    Kopacz, Nina; Csuka, Joleen Mary; Baqué, Mickael; Iakubivskyi, Iaroslav; Guðlaugardóttir, Hrefna; Klarenberg, Ingeborg J.; Ahmed, Mahid; Zetterlind, Alexandra; Singh, Abhijeet; Kate, Inge L. ten; Hellebrand, Eric; Stockwell, Brent; Stefánsson, Árni B.; Vilhelmsson, Oddur; Neubeck, Anna; Schnürer, Anna; Geppert, Wolf (2022-05)
    Lava tubes on Mars hold exciting potential for the preservation of biosignatures, which may survive on geological timescales in these isolated, stable environments. To support the development of future astrobiological mission concepts, we turn to ...
