TL;DR: Watering the Moon About a year ago, a spent upper stage of an Atlas rocket was deliberately crashed into a crater at the south pole of the Moon, ejecting a plume of debris, dust, and vapor that revealed water and other volatiles expected to be trapped in lunar polar soils.

Martian oxygen density at the exobase deduced from O I 130.4‐nm observations by Spectroscopy for the Investigation of the Characteristics of the Atmosphere of Mars on Mars Express
TL;DR: In this article, the authors used a three-dimensional Monte Carlo radiative transfer model describing each line of the O I 130.4-nm triplet in the upper atmosphere of Mars to determine the oxygen density in the Martian upper atmosphere.

Spectro-imaging observations of Jupiter’s 2 μm auroral emission. II: Thermospheric winds

TL;DR: In this paper, Raynaud et al. used the measured Doppler shifts of the H 2 and H 3 + lines near 2.1μm to derive the ion and neutral wind velocities in Jupiter's high latitude thermosphere.

Mercury and Moon He exospheres: Analysis and modeling
TL;DR: In this paper, the energy accommodation of the exospheric He particles interacting with the surface can be roughly constrained using Apollo 17 and Mariner 10 measurements, which can be explained satisfactorily by any of the present theories on the gas-surface interaction in surface-bounded exospheres.

Hydrogen in the extended Venus exosphere
Magda Delva,Martin Volwerk,Christian Mazelle,Jean-Yves Chaufray,Jean-Loup Bertaux,T. L. Zhang,Zoltán Vörös +6 more
TL;DR: In this article, the authors used the presence of proton cyclotron waves as an early tracer of ionized planetary hydrogen picked-up by the solar wind, especially in the region upstream of the bow shock.
