In what seems to have become somewhat of an annual event researchers have announced the discovery of water on Mars yet again—although this time it’s more of a confirmation of a previous announcement (with a bit extra for good measure) but not everyone is agreeing on the same interpretation of the evidence..then again, that’s how science is supposed to work.
The most recent announcement of water on Mars was made today by ESA following a paper published in Nature Astronomy in which a team of researchers used radar data gathered by the Mars Express spacecraft to bolster previous claims made in 2018 of a wide, shallow lake of super-salty liquid water nearly a mile below layered ice and dust deposits at Mars’ south pole.
The team’s reanalysis of the radar data appears to not only confirm the earlier discovery, which itself was the result of a decade of painstaking research, but also identifies three more possible ...
