Megatsunami on Mars linked to an asteroid strike 3.4 billion years ago

The event is likened to the Chicxulub collision on Earth.

A study has found that the megatsunami that swept Mars around 3.4 billion years ago was caused by an asteroid strike on one of its oceans. The event is compared to the likes of the Chicxulub collision—which is believed to have wiped out dinosaurs from the face of the earth about 66 million years ago.

Researchers, led by Alexis Rodriguez of the Planetary Science Institute in Arizona, have also suggested that NASA’s Viking 1 Lander, which was deployed on a mission to find evidence of life on Mars in 1976, could have landed near the crater of this megatsunami.

The new study published in the journal Scientific Reports analyzed “maps of Mars’ surface, created by combining images from previous missions to the planet, and identified an impact crater that could have caused the megatsunami,” as mentioned in the press release.
