UCLA Scientist Discovers Plate Tectonics On Mars

Reader SternisheFan links to a press release at UCLA, and excerpts from it another bit of Mars news: "For years, many scientists had thought that plate tectonics existed nowhere in our solar system but on Earth. Now, a UCLA scientist has discovered that the geological phenomenon, which involves the movement of huge crustal plates beneath a planet's surface, also exists on Mars. 'Mars is at a primitive stage of plate tectonics. It gives us a glimpse of how the early Earth may have looked and may help us understand how plate tectonics began on Earth,' said An Yin, a UCLA professor of Earth and space sciences and the sole author of the new research."

I think I'll wait...

...for the followup papers by other scientists examining his findings before I make a conclusion. I have a friend who actually is a planetary geologist and focuses most of his attention on Mars, and I haven't heard any of this from him.

Forgive me, IANAPG but didnt Mars cease to be geologically active long ago.

That's what we thought, which makes this finding surprising.

Also, if earth is the only planet with active tectonics why is Venus literally covered with active volcanoes and an atmosphere thousands of times denser than earth?

It's literally covered with active volcanoes, rather than having them occur largely along narrow zones near fault lines, precisely because it appears to lack plate tectonics, which would cause it to vent its internal heat more like Earth does rather than it's peculiar Venusian way...
