At some point, Venus may have had its own form of plate tectonics – possibly different from the plate tectonics here on Earth. Water and rock measurements obtained from the DAVINCI mission, combined with the Venus global mapping information by NASA’s VERITAS mission, another recently selected mission to Venus that is managed by NASA’s Jet Propulsion Laboratory in Southern California, can be used to decipher how these tectonic patterns may have operated on Venus, and why the planet was unable to sustain them in a fashion similar to Earth.

But it would be a mistake to imagine that we are benignly coming full circle, or even that we are finding that the old ways are still the most efficient. A tectonic shift has occurred.
