Mosses thrive in the most extreme environments on Earth, from the peaks of the Himalayas to the sands of Death Valley, the Antarctic tundra to the lava fields of active […]
Panspermia
Pseudo-panspermia of Phosphorus Species on the Early Earth
In the Earth system, Phosphorus (P) does not form a single phase, but mostly combines into compounds forming multiple minerals. Phosphate (P+5) is the majority P species in the Earth’s […]
Endospore Integrity And Viability Of Bacillus subtilis On Simulated Martian Regolith In Rotational UVC Radiation Exposures
Current understanding of Martian regolith has advanced due to various rover explorations. Due to this, there are now several variants of Martian regolith that are chemically known and commercially available.
Life On Earth Probably Needed Supplies From Space
After the formation of the Solar System, it took a maximum of three million years for the chemical composition of the Earth’s precursor to be completed. This is shown by […]
Astrovirology, Astrobiology, Artificial Intelligence: Extra-Solar System Investigations
This chapter attempts to encompass and tackle a large problem in Astrovirology and Astrobiology. There is a huge anthropomorphic prejudice that although life is unlikely, the just-right Goldilocks terrestrial conditions […]
Astrochemistry: Space Ice Is Less Like Water Than We Thought
“Space ice” contains tiny crystals and is not, as previously assumed, a completely disordered material like liquid water, according to a new study by scientists at UCL (University College London) […]
Meteorite-common Amino Acid Induces Formation Of Nanocavities In Clay Mineral
Researchers at the universities of Amsterdam and Utrecht have observed the formation of nanocavities in montmorillonite clay under exposure to gamma-aminobutyric acid, a molecule commonly found on meteorites.
Virolithopanspermia: Might Viruses Be Transported In Rocks Through Space?
Material can apparently move between planets, at least on rare occasions. For example, meteorites have been found on Earth that appear to have originated on Mars, or even outside our […]
Extremotolerant Bacteria Identified In The NASA Mars Phoenix Cleanroom
Abstract Background Human-designed oligotrophic environments, such as cleanrooms, harbor unique microbial communities shaped by selective pressures like temperature, humidity, nutrient availability, cleaning reagents, and radiation. Maintaining the biological cleanliness of […]
Exposure of Phage T7 To Simulated Space Environment: The Effect Of Vacuum and UV-C Radiation
The experiment “Phage and Uracil Response” (PUR) will be accommodated in the EXPOSE facility of the International Space Station (ISS). Its objective is to examine and quantify the effect of […]
