Amorphous materials, which are rarely studied on Earth, yield insights into the history of Gale Crater and the early Martian environment.
The Past, Present, and Future of Extraterrestrial Sample Return
Retrieving samples from distant solar system bodies has revolutionized our understanding of the cosmos and our place in it.
Researchers Find Bacterial Communities Deep Beneath the Atacama
Extremophile microbes exist in the gypsum-rich “fringes” of the driest place on Earth.
Mars Mission’s Monetary Roller Coaster Hits New Lows
In February, the NASA research center laid off more than 500 people, citing congressional budget uncertainties over the controversial Mars Sample Return mission. What is its path forward?

The discovery of Noctis Mons could make the region a target for future Mars missions.
Towards a Unified Framework for Earth, Mars, Titan, and Exoplanets
From a simple set of in situ or synthetic data, a general unified model has been developed to calculate turbulent fluxes and evaporation rates on any rocky body with an atmosphere.
Salty Soil May Release Methane on Mars
Through roving and drilling, Mars Curiosity Rover may be breaking up the ground’s salty, hardened soils that seal methane, possibly causing a temporal, local methane spike.
