From the new NASA data and evidence cards about the channel on Mars, several key insights have emerged:

• The channel on Mars is located on a downhill slope, and at its base, there is a distinctive triangle-shaped landform. This landform is a significant clue in understanding the channel's formation

• Close-up images and rock analyses near the channel reveal the presence of conglomerate rocks, which on Earth typically form in environments with flowing water. This supports the idea that the channel may have been carved by flowing water rather than lava, although evidence from flowing lava models also shows some similarities

• The combination of satellite imagery, rover data, and geological comparisons to Earth suggests that water was likely involved in shaping the channel, as water erosion creates features similar to those observed on Mars

• Additional NASA findings from the Curiosity rover, such as the discovery of sulfate-rich layers and carbonate minerals like siderite, support the existence of ancient water and a thicker carbon dioxide atmosphere on Mars, which would have allowed liquid water to persist and contribute to channel formation

In summary, the new information from NASA's data strengthens the claim that the channel on Mars was formed primarily by flowing water, evidenced by the geological features at the channel's base and mineralogical findings consistent with aqueous processes. The triangle-shaped landform at the channel's base and the types of rocks found there are key pieces of evidence supporting this conclusion
