Microbial Rock Inhabitants Survive Hypervelocity Impacts on Mars-Like Host Planets: First Phase of Lithopanspermia Experimentally Tested
Gerda Horneck,Dieter Stöffler,Sieglinde Ott,Ulrich Hornemann,Charles S. Cockell,Ralf Moeller,C. Meyer,Jean-Pierre de Vera,Jörg Fritz,Sara Schade,Natalia Artemieva,Natalia Artemieva +11 more
TL;DR: A vital launch window for the transport of rock-colonizing microorganisms from a Mars-like planet was inferred, which encompasses shock pressures in the range of 5 to about 40 GPa for the bacterial endospores and the lichens, and a more limited shock pressure range for the cyanobacterium.

Experimental evidence for the potential impact ejection of viable microorganisms from Mars and Mars-like planets
Dieter Stöffler,Gerda Horneck,Sieglinde Ott,Ulrich Hornemann,Charles S. Cockell,Ralf Moeller,Ralf Moeller,C. Meyer,C. Meyer,Jean-Pierre de Vera,Jörg Fritz,Natalia Artemieva +11 more
TL;DR: In this paper, the authors showed that the survival of Bacillus subtilis and Xanthoria elegans up to 45 GPa and of Chroococcidiopsis sp. up to 10 GPa supports the possibility of transfer of life inside meteoroids between Mars and Earth.

Shock experiments in support of the Lithopanspermia theory: The influence of host rock composition, temperature, and shock pressure on the survival rate of endolithic and epilithic microorganisms
C. Meyer,Jörg Fritz,Martin Misgaiski,Dieter Stöffler,Natalia Artemieva,Ulrich Hornemann,Ralf Moeller,Jean-Pierre de Vera,Charles S. Cockell,Gerda Horneck,Sieglinde Ott,Elke Rabbow +11 more
TL;DR: The most favorable conditions for the impact ejection from Mars for microorganisms would be (1) low porosity host rocks, (2) pressures <10−20 GPa, and (3) low ambient temperature of target rocks during impact as discussed by the authors.

TL;DR: In this article, a simulation of microorganisms on Mars is used to reveal interactions between organisms and present geology on Earth and Mars, and the resulted traces (bio-signatures) on rocks formed by life forms may serve for future rover projects as reference system to search for present or past life on other planets.
