Detection of Water in the LCROSS Ejecta Plume
TLDR
The Lunar Crater Observation and Sensing Satellite (LCROSS) mission was designed to provide direct evidence that water ice may be presented in permanently shadowed craters of the Moon, and spectral bands of a number of other volatile compounds were observed.

Fluxes of fast and epithermal neutrons from Lunar Prospector: evidence for water ice at the lunar poles.
TLDR
Maps of epithermal- and fast-neutron fluxes measured by Lunar Prospector were used to search for deposits enriched in hydrogen at both lunar poles, and data are consistent with deposits of hydrogen in the form of water ice that are covered by as much as 40 centimeters of desiccated regolith within permanently shaded craters near both poles.

Elemental composition of the lunar surface: Analysis of gamma ray spectroscopy data from Lunar Prospector
[1] Gamma ray spectroscopy data acquired by Lunar Prospector are used to determine global maps of the elemental composition of the lunar surface. Maps of the abundance of major oxides, MgO, Al2O3,…

Global distribution of near-surface hydrogen on Mars
[1] Neutron data observed using the Neutron Spectrometer aboard 2001 Mars Odyssey provide a lower limit to the global inventory of Martian water-equivalent hydrogen. Hydrogen-rich deposits ranging…

The Earth's plasma sheet as a laboratory for flow turbulence in high-β MHD
The bulk flows and magnetic-field fluctuations of the plasma sheet are investigated using single-point measurements from the ISEE-2 Fast Plasma Experiment and fluxgate magnetometer. Ten…
