The Mars that once was
Scientists have located an impact crater linked to powerful tsunamis that swept across part of ancient Mars.
The team believe an asteroid triggered 150m-high waves when it plunged into an ocean thought to have existed on northern Mars three billion years ago.
Lomonosov crater in the planet’s northern plains fits the bill as the source of tsunami deposits identified on the surface.
Details were outlined at the 48th Lunar and Planetary Science Conference.
