Traces of a giant flood on Mars

According to ESA experts, the cause of the giant flood was a combination of processóIn volcanic, movementóin tectonics and the collapse and subsidence of the groundóin whichóre led to the release of huge amounts of wód ground. As a result, the water flooded the entire Kasei Valles region, leaving behind traces thatóre we can see thanks to probes and rovers sent to Mars.

The Mars Express probe has taken phenomenal pictures of the channelóIn outflows in the Kasei Valles region – is three thousand kilometers longóinto the canyon systemów. Located in the neighborhood of 25 kilometers wideów crater – Worcester Crater (the largest crater in the picture, slightly to the left of the central part) – provided evidenceów on the passage of gigantic masses of water there. According to ESA specialists, the rock material ejected from the crater during the impact, or rather its alignment, indicates the direction in which theówhich water was going. The shape of the ground also suggests fluctuating levelsóinód or róThe periodóin flooded.

For porównania smaller crater adjacent to Worcester Crater has a completely different arrangement of rock material. Debris ejected during the impact surrounds it on all sides in roughly similar amounts. ESA scientists found that it had already formed after the passage of głóin a major flood wave. Wzór of scattered rock material matches the impact of some celestial body at a time when water covered the area.

The crater shown in the photo on the right in górthern part of it is located on a plateau about a kilometer higher than the two craters discussed earlierów.
