Tardigrades can survive on the surface of Mars.

INSUFFICIENT LEANING
Recorded sources
5 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Tardigrades can survive on the surface of Mars?

Unclear. Several sources show tardigrades tolerate space vacuum, radiation, desiccation, and Mars-relevant perchlorate salts, but none tests survival on the Martian surface itself, so the evidence only partially supports the claim.
