Mars' Hellas Basin 4 Billion Years Ago - Deepest Place On Mars

Hellas is by far the deepest place on Mars, but besides that it is also gigantic, taking up about half the surface area of mainland United States. Hellas is also the largest well preserved crater on Mars, its outlines are obvious. In this video I take a look what studies have to say with regards to its rich history and with that construct a timeline of what happened to it during its most dynamic period. Many clips in this video were made with Space Engine. 0:00 Introduction 4:47 Possibility of a giant ice covered lake - 2001 study 7:25 A bit of skepticism - 2017 study 15:00 Hope revival for a "Hellas ocean" - 2020 study 21:32 Honeycomb terrain as evidence for a big lake - 2016 study 31:44 How crater counting gives us the the age of Hellas - 2008 study 33:51 Conclusion Music: 1.
