Home / Science / Mars Asteroid Tsunami: Ancient Impact Triggered a 1000-ft Wave of "Blue Water" on the Red Planet | Science | news


An asteroid crashed into the earth 66 million years ago, creating a 150km wide crater in what is now the Gulf of Mexico. The resulting blast echoed around the world and the impact also triggered a 100 meter high mega-tsunami. Now, a new study suggests that Mars had suffered a similar mega-tsunami event 3.7 billion years ago, and scientists believe it was an ocean impacting the apparent asteroid impact of Ground-Zero future search for extraterrestrial life on Mars had.

Dr. François Costard, a planetary geomorphologist at the French National Center for Scientific Research, told Express.co.uk how two consecutive waves were formed during an asteroid impact on Mars.

He said, "It was a really big tsunami at high speed. At the very beginning, a crater with a diameter of 70 km was produced by the impact.

"As a result, a huge volume of water with a wave propagation of 60 m / s was ejected.

"The initial wave was about 300 meters high. After only a few hours, this tsunami wave reached the Paleo Coast, which is only a few hundred kilometers from the impact crater.

9659002] "Eventually, there was a second wave propagation due to the filling of the Marso Ocean in this crater, which caused a kind of rebound."

The researchers focused on the Lomonosov crater, which they considered likely

The Martian crater is very similar to the marine craters here on Earth.

The researchers concluded that the Mars Ocean could be a good place to look for evidence of life on Earth planet.

Some people believe that the ocean would have been fed by underground waters that are so geochemically signatures of an ancient microbiology could indicate that basic forms of alien life are still suspected under the surface of Mars in liquid acquirers Rocks are to be found.

Dr. But Costard warns against making any premature conclusions about the presence of Mars.

He said, "Yes, is it a good condition for the presence of life? It is very difficult to say something about it.

"And it would be interesting to land on the surface of this crater.

"Before that, however, we need much more detailed studies of this impact crater and a few more surveys of the crater-lowland terrain. "

The question of whether the red planet may once have been Blue surfaces again with the discovery of evidence that the support ancient tsunamis on Mars.

This is of particular interest to NASA's Ames as it invests in exposing evidence of water on Mars, an essential step on the road to supporting extraterrestrial life.

Dr. Alexis Rodriguez stated that the Lomonosov tsunami crater could be a prime landing site candidate to seek evidence of Mars' life.

The ocean was possibly fed by catastrophic underwater flooding and caches of liquid water.

In this case, sediments in the north could "be a window into the subterranean habitability of Mars," Dr. Rodriguez added.
