Abstract

A detailed map of Venus was released by Magellan scientists on October 29. Magellan has just completed its 3,000 orbit of Venus and, according to the project's chief scientist Steve Saunders, “We now have a better globe of Venus than of Earth, because no maps of Earth have so completely traced the surface topography hidden beneath the oceans.”

But the data have not lead researchers to any consensus on whether the surface of Venus was created by one long episode of catastrophic activity 800 million years ago or if continuous eruptions have steadily spread lava over the plains and transformed the surface over time.
