The Goldstone Solar System RADAR (GSSR) group at JPL produced a Digital Elevation Model (DEM) of the lunar south pole using data obtained in 2006. This model has 40-meter horizontal resolution and about 5-meter relative ...

Here-to-fore, sailcraft mission and system studies have focused on sailcraft applications in support of NASA’s science missions and, in a few studies, on the needs of other federal agencies such as the National Oceanic and ...

Lunar prospector, the third mission in the faster, better, cheaper NASA Discovery program, was successfully launched from Cape Canaveral on Januray 6, 1998.

Observations with radio telescopes address key problems in cosmology, astrobiology, heliophysics, and planetary science including the first light in the Universe (Cosmic Dawn), magnetic fields of extrasolar planets, particle ...

This paper describes our effort in searching different lunar relay architectures and assessing their coverage performance and other pros and cons for RF and optical links. Regarding RF links, we considered three notional ...

Onboard localization capabilities for planetary rovers to date have used relative navigation, by integrating combinations of wheel odometry, visual odometry, and inertial measurements during each drive to track position ...
