The area containing the clay-bearing mounds is geologically connected to Oxia Planum, which is where Rosalind Franklin will be headed when it launches in 2028 in search of past life on Mars. It now ...

The car-sized Curiosity rover has spotted evidence of once quite hospitable environs on Mars.

Many believe these low-lying plains were once host to giant lakes, rivers, or possibly oceans. Accumulating evidence increases the idea that Mars must have been much more wet a place during the ...

Scientists hope to uncover signs of past life and confirm the existence of an ancient ocean. The findings, published in Nature Geoscience on 20 January, provide fresh insights into Mars' wet ...

with oceans, lakes and rivers, "but the water disappeared about 3 billion years ago". This means Mars rovers have explored "dried up lakebeds and empty river channels". But the data from a NASA ...

So - how did a mission that went to Mars to analyse marsquakes and seismic activity discover what may be an ocean's worth of water over 10 kilometres below the surface? The C-S-I-R-O's Glen Nagle ...

"Our new picture of Mars," Pollack said yesterday, "is much like the Earth without oceans." The dark areas are contintents, and the bright areas are dry ocean basins. There are differences ...

has found new geological evidence suggesting that Mars might have once hosted a vast ocean. The study, published in Nature, strengthens the theory that an ocean may have covered nearly a third of ...

Related: Ocean's worth of water may be buried within Mars — but can we get to it? On Earth — for example, in the western United States — we find such hills in the form of buttes and mesas in ...

So - how did a mission that went to Mars to analyse marsquakes and seismic activity discover what may be an ocean's worth of water over 10 kilometres below the surface? The CSIRO's Glen Nagle ...

Indeed, the evidence is now overwhelming that Mars was once warmer, and wet, with rivers, lakes and possibly even oceans that existed almost four billion years ago. Now researchers led by McNeil have ...
