How Fast Did an Ancient Martian Delta Form?
Terrestrial meander migration rates are used to estimate a formation timescale of decades for Jezero delta on Mars.
How Do Submarine and Terrestrial Canyons Compare?
Insights from a new study could spark discoveries about Martian landscapes and also help researchers get to the bottom of canyon formation here on Earth.
Lomonosov: The Crater That Started a Martian Mega Tsunami
Three billion years ago, on Mars, the shores of an ocean may have been flooded by a mega-tsunami. Now the crater left by the bolide impact that probably triggered the tsunami has been identified.
Mapping Subglacial Meltwater Channels
Researchers find that past studies underestimate the friction meltwater channels exert on glaciers by orders of magnitude.
How Do Intergranular Particles Affect the Flow of Ice?
Laboratory experiments that indicate rock particles can impede sliding along grain boundaries in ice may help researchers more accurately determine the composition of planetary ice masses.
A New Way to Analyze Evidence of Martian Oceans
Mars’s aqueous past holds the answers to many questions about the Red Planet. A new study provides a tool for scouring planetary surfaces for ancient shorelines.
What Ancient Rivers on Mars Reveal About Its “Great Drying”
Dried-up rivers on Mars suggest that the planet was wet in the not-too-distant past.
Revisiting Enigmatic Martian Slope Streaks
Slope streaks of different sizes and shapes are a common feature on the surface of Mars, but scientists disagree about the mechanisms for their formation and development.
A New Model for River Meanders
A river’s twists and turns are shaped by its past flood events.
