The geophysical evolution and astrobiological potential of ocean worlds are indelibly linked to the chemical compositions of their oceans and ice shells.
NASA’s Dragonfly rotorcraft is beginning to take shape – literally – with the delivery of the panels that make up the rotorcraft lander’s body. Built from ultra‑lightweight honeycomb panels designed […]
Coordinating with the CaSSIS instrument on the ExoMars Trace Gas Orbiter, we acquired an image at this site for seasonal monitoring.
Saturn’s moon Titan is a prime destination for investigating prebiotic chemistry beyond Earth, particularly at impact crater sites where transient liquid water may have enabled aqueous reactions between organic molecules.
Scientists at Northern Arizona University are conducting a research study gathering views from members of the planetary science community on field-based studies and the interest in a potential centralized facility […]
Caltech researchers have identified geological features on Mars that could point to the existence of a long-dried ocean that once covered a third of the Red Planet’s surface.
Thermal measurements constrain the physical properties of icy satellite surfaces, including grain size, porosity, and regolith structure. On Europa, analyses of the Galileo Photopolarimeter-Radiometer (PPR) dataset revealed thermal inertia heterogeneities, […]
Editor’s note: when our first missions – human or robotic – arrive at a new world we’ll want to do glean as much information from space – via fly by […]
Noticeable change on Mars often takes millions of years – but the European Space Agency’s Mars Express has captured a blanket of dark ash creeping across the planet in just […]
Europa’s double ridges often display lower albedo and redder color than their surroundings. Their unique topography may cause sublimation-driven darkening due to illumination and self-heating, a process known as thermal […]
