A Global High-Resolution Hydrological Model to Simulate the Dynamics of Surface Liquid Reservoirs: Application on Mars

Aerosol deposition on the surface following 5 Mars years of 2.5 l/s release and 15 Mars years of shutoff. The distribution is comparatively uniform, with more deposition at low elevations, high latitudes and close to the release site (marked by the black cross). Including radiative cloud feedbacks makes little difference to the deposition. -- astro-ph.EP

Images of tardigrades with mineral coatings. Each image is annotated with the sample, simulant and time of exposure in days. Before treatment: Panels A–C show example active animals from inoculums with smooth exteriors. After treatment: Panels D–G show examples of active animals with mineral particles visible as a rough, bumpy exterior (arrows point to examples). Panels H–M show inactive (presumed dead) animals with mineral particles attached. Panels H, K and M show examples of bloated animals. Scale bar is 100 microns and the same size in each image. Images without scale bars are from videos and are shown at approximately the same scale. -- International Journal of Astrobiology
