The ice along Antarctica’s ‘grounding lines’ has been largely stable over the past 30 years – but ice has retreated by more than 40 km in some areas, a new […]
We simulate Venus’ evolution with a coupled one-dimensional solar-atmosphere-lithosphere-mantle-core model to predict currently unobservable features and its eruptive mass flux.
One of the final three candidate landing sites for the Mars 2020 mission was northeast Syrtis, along with Gusev Crater/Columbia Hills and the eventual landing site for the Perseverance rover, […]
The goal of this expedition went far beyond collecting sediment cores. Scientists also set out to sample the water stored within the sediments, including from sandy layers that act as […]

This specimen shows the most common types of crack networks observed in Bennu samples. One has an extensive and connect framework of curved cracks, whereas the other has sparse, straight and flat fractures.

In one of the biggest surprises of NASA’s OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged world covered in large boulders, with few of the […]
How can we measure time more than 500 million years into the past? A study recently published in Nature Communications by researchers at the University of Lausanne presents a new […]
Hi Keith, The team and I have been home for about two weeks now, settling back into the familiar rhythms of home and work after our time in Antarctica. Our […]
Competing processes shape Europa’s surface: geological activity replenishes material through resurfacing, while bombardment by charged particles alters surface chemical composition. Each process leaves distinct spectral signatures.
NASA Dragonfly’s integration and testing – the activities involved in assembling the mission’s rotorcraft lander and testing it for the rigors of launch and extreme conditions of space – is […]
We investigate the magnetic signature of oceanic circulation in Ganymede’s subsurface ocean using kinematic induction modeling. Our approach couples zonal jet flows from rotating thermal convection simulations with magnetic field […]
