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 …

A planet's crust bears witness to the history of planetary formation and evolution, but for
Mars, no absolute measurement of crustal thickness has been available. Here, we …

The accumulation of detailed ion flux measurements from long-lived spacecraft orbiting the
solar system's terrestrial planets have enabled recent studies to estimate the rate of solar …

We present the first observations of seismic waves propagating through the core of Mars.
These observations, made using seismic data collected by the InSight geophysical mission …

The InSight lander carried an Instrument Deployment System (IDS) that included an
Instrument Deployment Arm (IDA), scoop, five finger “claw” grapple, forearm-mounted …

Abstract Knowledge of the interior structure and atmosphere of Mars is essential to
understanding how the planet has formed and evolved. A major obstacle to investigations of …

Constraints on the composition of Mars principally derive from chemical analyses of a set of
Martian meteorites that rely either on determinations of their refractory element abundances …

Mars' magnetic field has been measured at large scale by orbiting spacecraft and at very
small scale via Martian meteorites. Here we report on a ground magnetic survey on metre to …

Analyses of seismic data from the InSight mission have provided the first in situ constraints
on the thickness of the crust of Mars. These crustal thickness constraints are currently limited …

The 4.1-billion-year-old meteorite Allan Hills 84001 (ALH 84001) may preserve a magnetic
record of the extinct martian dynamo. However, previous paleomagnetic studies have …
