A Systematic Study Of Hot Oxygen Production And Escape From Martian Atmosphere In Response To Enhanced EUV Irradiance From Solar Flares
The study of the evolution of Martian atmosphere and its response to EUV irradiation is an extremely important topic in planetary science. One of the dominant effects of atmospheric losses […]
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 […]
Offworld Biotech: Growing Microalgae In Microgravity
NASA astronaut and Expedition 73 Flight Engineer Nichole Ayers shows off research hardware to study how microalgae grow in spaceflight conditions such as microgravity and radiation.
Far-ultraviolet Flares and Variability of the Young M dwarf AU Mic: a Non-detection of Planet c in Transit at Lyman-alpha
Atmospheric escape’s potential to shape the exoplanet population motivates detailed observations of systems actively undergoing escape.
Planet Formation In High UV Radiation Environments
The fundamental building blocks for planet formation can exist even in environments with extreme ultraviolet radiation, according to a new study by an international collaboration led by Penn State astronomers.
Ultraviolet And Biological Effective Dose Observations At Gale Crater, Mars
The incident ultraviolet (UV) irradiance on the surface of Mars is strongly sterilizing and plays a critical role in atmospheric and near-surface photochemistry.
The Blinking Crystallinity Of Europa: A Competition Between Irradiation And Thermal Alteration
The surface of Europa experiences a competition between thermally-induced crystallization and radiation-induced amorphization processes, leading to changes of its crystalline structure.
Astronaut Anne McClain Conducts Offworld Space Botany Research
Anne McClain: How does space radiation affect plants? NASA’s Advanced Plant EXperiment-12 (APEX-12) seeks to find out.
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 […]
