Although the majority of volcanic and tectonic activity on Mars occurred during the first 1.5
billion years of its geologic history, recent volcanism, tectonism and active seismicity in …

Spacecraft-to-spacecraft tracking observations from the Gravity Recovery and Interior
Laboratory (GRAIL) have been used to construct a gravitational field of the Moon to …

Radio tracking of the MESSENGER spacecraft has provided a model of Mercury's gravity
field. In the northern hemisphere, several large gravity anomalies, including candidate mass …

Orbital images from the MESSENGER spacecraft show that~ 27% of Mercury's surface is
covered by smooth plains, the majority (> 65%) of which are interpreted to be volcanic in …

Abstract The BepiColombo Laser Altimeter (BELA) is the first European laser altimeter
constructed for interplanetary flight. BELA uses a 50 mJ pulsed Nd: YAG laser operating at …

Abstract Space laser altimeter is an active remote sensing instrument to measure
topographic map of Earth, Moon and planetary. The space laser altimeter determines the …

Geodetic analysis of radio tracking measurements of the MErcury Surface, Space
ENvironment, GEochemistry, and Ranging spacecraft while in orbit about Mercury has …

The deep nitrogen-covered basin on Pluto, informally named Sputnik Planitia, is located
very close to the longitude of Pluto's tidal axis and may be an impact feature, by analogy with …

Mercury, a planet with a lithosphere that forms a single tectonic plate, is replete with tectonic
structures interpreted to be the result of planetary cooling and contraction. However, the …

We present the analysis of 205 spatially resolved measurements of the surface composition
of Mercury from MESSENGER's X‐Ray Spectrometer. The surface footprints of these …
