Microbes that survive transport to and in the stratosphere endure extremes of low temperature, atmospheric pressure, and relative humidity, as well as high fluxes in ultraviolet radiation (UVR).
C11H+9 ion is the dominant fragment cation formed from methyl-naphthalene (MeNp) and dimethyl-naphthalene (diMeNp).
Radiation is one of the most pervasive environmental stressors that has profoundly influenced microbial evolution, driving the development of intricate survival strategies in extreme environments.
In December 2023, scientists looking at Mars data stumbled across something completely unexpected — observations of an atmospheric effect never before seen in the Red Planet’s atmosphere.
An international team is sending microbes from Antarctica and Chile to the International Space Station (ISS) to study how they withstand radiation and other spaceflight stressors.
TRAPPIST-1 is an ultra-cool dwarf that flares frequently. These flares shape the surrounding planets’ high-energy irradiation environments, with consequences for atmospheric chemistry and escape, and they can contaminate transmission spectroscopy […]
How microbial communities respond to extreme conditions in the stratosphere remains unclear.
In the next years, several space missions will search for evidence of life on exoplanets, focusing on robust biosignatures associated with oxygenic photosynthesis, including atmospheric oxygen accumulation and the Vegetation […]
Planetary protection hinges on understanding microbial survival following reduction procedures, the stressors of space travel, and exposure to extraterrestrial environmental conditions. This study identified 23 fungal strains isolated from NASA […]
Spaceflight imposes substantial physiological stress on reproductive systems, yet relevant transcriptomic data remain fragmented across repositories. To address this need, we developed ASTROREPOMICS, a web-based platform that integrates 17 rigorously […]
