HiRISE Mars 4K (NASA): Once Upon a Martian Lake



While there was not much by way of science rationale for this observation, Terra Sirenum is a large area of Mars in the Southern Hemisphere and is believed to have once held a lake that eventually drained through Ma’adim Vallis. The THEMIS instrument on the Mars Odyssey orbiter has detected evidence of chloride-based minerals dated well over 3.5 billion years. This image shows some lighter-toned bedrock that may represent these minerals.

This is a non-narrated clip with ambient sound. Enhanced color image is less than 1 km (under 1 mi) across and the spacecraft altitude was 255 km (158 mi). For full images including scale bars, visit the source link.

  1. NaCl? Was it a salt lake? Ariadnes Colles, Gorgonum and Atlantis Chaos are a very interesting area of Mars, home to the ancient lake of Eridania. 3.5 billion years ago it was Hesperian, I thought it was older, than Noachian
