Editor’s note: Astronaut Thomas Pesquet carries out investigations with the spectrometer associated with the ESA Electronic FieldBook
The Mars Life Explorer (MLE) mission concept offers a critical opportunity to investigate whether extant life exists within the mid-latitude ice deposits of Mars.
The Earth possesses many environmental extremes that mimic conditions on extraterrestrial worlds. The stratosphere at 30-40 km altitude closely resembles the surface of Mars in terms of pressure, temperature, and […]
The Life Detection Knowledge Base (LDKB; https://lifedetectionforum.com/ldkb) is a community-owned web resource that is designed to facilitate the infusion of astrobiology knowledge and expertise into the conceptualization and design of […]
Editor’s note: If you search for a definition for a tricorder you’ll find things like this from Wikipedia: “A tricorder is a fictional handheld sensor that exists in the Star […]
Editor’s note: with recent speculation about the potential habitability of the clouds of Venus and the long-hypothesized notion of airborne life forms on Saturn and Jupiter these studies from Earth […]
Planetary caves are desirable environments for the search for biosignatures corresponding to extant or extinct extraterrestrial life due to the protection they offer from surface-level solar radiation and ionizing particles.
We explore a hypothesis in which the detection of classes of lipid-like molecules with similar abundance-averaged lengths would constitute a biosignature for other worlds.
The incident ultraviolet (UV) irradiance on the surface of Mars is strongly sterilizing and plays a critical role in atmospheric and near-surface photochemistry.
