Near-IR reflectance spectra (0.4-2.4 µm) of water ice and smectite mixtures Poch et al., 2016b:

• evolution of the water/dust spectral features during sublimation
• water-free porous sublimation residues made of smectite

Near-IR reflectance spectra (0.4-2.4 µm) of biomolecules dry powders at 293±2 K Poch et al., 2017:

• proteins, DNA, phospholipids, carbohydrates, pigments

Near-IR reflectance spectra (0.7-4.0 µm) of spherical water ice particles:

• of well-controlled size distributions from about 2 to 100 µm
• produced with our Setups for the Production of Icy Planetary Analogues: SPIPA-A 4.5±2.5 µm, SPIPA-B 67±31 µm, SPIPA-C 2-100 µm
• at different temperatures (173 and 223 K)
• before/after metamorphism (sintering)

Near-IR reflectance spectra (0.4-2.4 µm) of a pigmented microorganism (Deinococcus radiodurans) Poch et al., 2017:

• pure D. radiodurans hydrated or desiccated
• D. radiodurans mixed with silica sand (10¹⁰ organisms/mL) compared to pure silica sand
• D. radiodurans mixed with liquid water (10¹⁰ org./mL) compared to pure liquid water
• D. radiodurans inside water ice particles (10⁵, 10⁷, 10⁹ org./mL) compared to pure water ice particles
• Evolution of D. radiodurans spectral signatures during sublimation of the ice
