The magnetometer instrument MPO-MAG on-board the Mercury Planetary Orbiter (MPO) of
the BepiColombo mission en-route to Mercury is introduced, with its instrument design, its …

Abstract The SIMBIO-SYS (Spectrometer and Imaging for MPO BepiColombo Integrated
Observatory SYStem) is a complex instrument suite part of the scientific payload of the …

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 …

Ultrashort-period (USP) exoplanets have orbital periods shorter than 1 day. Precise masses
and radii of USP exoplanets could provide constraints on their unknown formation and …

Proxima b is a planet with a minimum mass of 1.3M⊕ orbiting within the habitable zone (HZ)
of Proxima Centauri, a very low-mass, active star and the Sun's closest neighbor. Here we …

Permeability controls fluid flow in fault zones and is a proxy for rock damage after an
earthquake. We used the tidal response of water level in a deep borehole to track …

The recent determination of the gravity field of Mercury and new Earth‐based radar
observations of the planet's spin state afford the opportunity to explore Mercury's internal …

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 …

Ceres is the largest body in the asteroid belt with a radius of approximately 470 km. In part
due to its large mass, Ceres more closely approaches hydrostatic equilibrium than major …

Abundant carbon was identified on Mercury by MESSENGER, which is interpreted as the
remnant of a primordial graphite flotation crust, suggesting that the magma ocean and core …
