Abstract Several outstanding issues concerning the ionosphere of Mars can be addressed with the support of radio occultation observations acquired near the solar zenith angle limit of 45 $$^{\circ }$$ ∘ . First, two fundamentally different types of

The story of human exploration of space tends to capture the imagination but there has been a distinct lack of study into the Royal Air Force’s own history of space operations. This article reflects upon another ‘giant leap’ that occurred short

Measurements made by the Voyager 2 spacecraft during its flybys of Uranus in 1986 found warm stratospheric and hot thermospheric temperatures that cannot be explained by solar energy alone. It contributes to what has become known as the “giant plan

Decline and recovery timescales surrounding eclipse are indicative of the controlling physical processes in Io’s atmosphere. Recent studies have established that the majority of Io’s molecular atmosphere, SO _2 and SO, condenses during its passag

The densities of three ion species in the Martian upper atmosphere were compared during the MY33 and MY34 Martian regional and global dust storms (RDS 2016 and GDS 2018, respectively) using data from the neutral gas and ion mass spectrometer of the M

In order to further evaluate the behavior of ionospheric variations at Mars, we investigate the Martian ionosphere-thermosphere (IT) perturbations associated with non-migrating thermal tides using over four years of Mars Atmosphere and Volatile Evolu

NASA’s Juno spacecraft performed close flybys of the Galilean moons Ganymede in June 2021 and Europa in September 2022. During each of these encounters, the Juno spacecraft passed behind the moons as observed from Earth, providing the geometry for

The primary objective of the Europa Clipper mission is to assess the habitability of Europa, an overarching goal that rests on improving our understanding of Europa’s interior structure, composition, and geologic activity. Here we describe the Grav
