Height scales of atmospheres of Solar System’s terrestrial planets. The solid lines show the temperature profiles against altitude, while the background colour reflects the atmospheric pressure. Horizontal dashed lines denote the average positions of atmospheric boundaries: tropopause (“t”), stratopause (“s”), and mesopause (“m”). Vertical cyan lines depict the extension of ionospheres (“i”) under typical conditions. The “⊙” symbol denotes the 100 mbar level. -- Space Science Reviews via PubMed

Upper Atmosphere Dynamics and Drivers of Volatiles Loss from Terrestrial-Type (Exo)Planets

by Keith CowingApril 6, 2026April 6, 2026

Volatile loss from exoplanetary atmospheres and its possible implications for the longevity of habitable surface conditions is a topic of vigorous debate currently.

The Europa Imaging System (EIS) Investigation

by Keith CowingJuly 17, 2025June 26, 2026

The Europa Imaging System (EIS) consists of a Narrow-Angle Camera (NAC) and a Wide-Angle Camera (WAC) that are designed to work together to address high-priority science objectives regarding Europa’s geology, […]
