A new study reveals Mars once had salt lakes just like Earth & went through wet & dry periods

As per new study, Mars had once salt lakes just like the ones on Earth and even has gone through wet and dry periods. Researchers examined geological terrains from Gale crater on Mars. Gale crater had formed about 3.6 billion years ago when a meteor hit Mars. The study co-author said salt ponds were eventually formed during the dry periods. Mars probably became drier over time & the planet lost its planetary magnetic field.
