Detection of lithium in the exosphere of Mercury [PDF]
Nature CommunicationsMercury’s exosphere contains various neutral species, including hydrogen, helium, sodium, potassium, calcium, magnesium, aluminum, iron, and manganese. Although lithium has been predicted to exist, it had not been detected until now. Here, we demonstrate

Exosphere - Bringing The Cloud Closer [PDF]
2020 IEEE/ACM International Workshop on Interoperability of Supercomputing and Cloud Technologies (SuperCompCloud), 2020 Exosphere provides researcher-friendly software for managing computing workloads on OpenStack cloud infrastructure. Exosphere is a user-friendly alternative to Horizon, the default OpenStack graphical interface. Exosphere can be used with most research cloud infrastructure, requiring near-zero custom integration work.

A transient enhancement of Mercury’s exosphere at extremely high altitudes inferred from pickup ions [PDF]
Nature Communications, 2020 Mercury has a global dayside exosphere that is very tenuous and does not extend far from the planet. Here, the authors show enhancement of neutral densities at high altitudes inferred from pickup ions that is most likely caused by the impact of a ...

Remote sensing of mercury sodium exospheric patterns in relation to particle precipitation and interplanetary magnetic field [PDF]
Scientific ReportsThe ground-based solar telescope THEMIS performed several observations of Mercury’s sodium exosphere in years 2011–2013, when the MESSENGER spacecraft was orbiting around the planet. Typical two-peak exospheric patterns were frequently identified.

The Evolution of a Spacecraft-Generated Lunar Exosphere. [PDF]
J Geophys Res Planets, 2020 AbstractUnderstanding how spacecraft alter planetary environments can offer important insights into key physical processes, as well as being critical to planning mission operations and observations. In this context, it is important to recognize that almost any powered lunar landing will be an active volatile release experiment, due to the release of ...

The Influence of Surface Binding Energy on Sputtering in Models of the Sodium Exosphere of Mercury
The Planetary Science Journal, 2022 We have simulated the sodium (Na) exosphere of Mercury to show how the exosphere is affected by the assumed surface binding energy (SBE) of Na in the sputtered component.

The relation between the surface composition anomaly and distribution of the exosphere of Mercury
Earth, Planets and Space, 2023 In celestial bodies with tenuous collisionless atmospheres, such as Mercury, the spatial distribution of the exosphere is expected to reflect the surface composition.

Terrestrial exospheric hydrogen density distributions under solar minimum and solar maximum conditions observed by the TWINS stereo mission [PDF]
Annales Geophysicae, 2015 Circumterrestrial Lyman-α column brightness observations above 3 Earth radii (Re) have been used to derive separate 3-D neutral hydrogen density models of the Earth's exosphere for solar minimum (2008, 2010) and near-solar-maximum (2012) conditions ...
