Building blocks of life such as amino acids, nucleobases, and fatty acids are central to prebiotic chemistry and represent key targets in the search for planetary biosignatures. In planetary materials, […]
Planetary surface missions currently operate cautiously. On Mars, communication delays between Earth and rovers (typically between four and 22 minutes), as well as data transfer constraints due to uplink and […]
Characterizing the surface and atmosphere of Earth-like planets in reflected light is a key goal for upcoming direct imaging surveys.
“Biosignatures and the Search For Life on Mars”, will be held in Iceland from 18 to 26 July 2026
Hi Keith, The team and I have been home for about two weeks now, settling back into the familiar rhythms of home and work after our time in Antarctica. Our […]
Scientists estimate that Earth is home to more than 100 million lakes. Among the most unusual is Lake Untersee, one of Antarctica’s largest and deepest surface lakes, known for its […]
Under its thick ice layer, Europa contains a shielded liquid water ocean where habitable conditions may exist. To effectively assess the habitability of this environment and the implications on putative […]
A portion of the Atacama Desert along Peru’s southern Pacific coast, featuring barren plains, rocky cliffs, vast sand dunes, and fertile river valleys, is pictured from the International Space Station […]
Carbon disulfide (CS2) is one of the sulfur-bearing species expected to be present in the interstellar medium (ISM). In this study, we investigated the surface reactions of solid CS2 with […]
Blood Falls is a unique feature that appears at the snout of the Taylor Glacier in the upper Taylor Valley, East Antarctica.
