By the end of 2018, 42 years after the landing of the two Viking seismometers on Mars,
InSight will deploy onto Mars' surface the SEIS (S eismic E xperiment for I nternal S tructure) …

Several seismic experiments were deployed on the Moon by the astronauts during the
Apollo missions. The experiments began in 1969 with Apollo 11, and continued with Apollo …

Clues to a planet's geologic history are contained in its interior structure, particularly its core.
We detected reflections of seismic waves from the core-mantle boundary of Mars using …

For 2 years, the InSight lander has been recording seismic data on Mars that are vital to
constrain the structure and thermochemical state of the planet. We used observations of …

High-resolution gravity data obtained from the dual Gravity Recovery and Interior Laboratory
(GRAIL) spacecraft show that the bulk density of the Moon's highlands crust is 2550 …

The giant impact hypothesis remains the leading theory for lunar origin. However, current
models struggle to explain the Moon's composition and isotopic similarity with Earth. Here …

The timeline of the lunar bombardment in the first Gy of Solar System history remains
unclear. Basin-forming impacts (eg Imbrium, Orientale), occurred 3.9–3.7 Gy ago, ie 600 …

Monitoring of vibrational eigenmodes of an elastic body excited by gravitational waves was
one of the first concepts proposed for the detection of gravitational waves. At laboratory …

Abstract The Gravity Recovery and Interior Laboratory (GRAIL) mission has sampled lunar
gravity with unprecedented accuracy and resolution. The lunar GM, the product of the …

Geochemical data for H 2 O and other volatiles, as well as major and trace elements, are
reported for 377 samples of lunar volcanic glass from three chemical groups (A15 green …
