Abstract

Venus remains geologically active in at least two places, according to data from NASA's Magellan mission, which will be terminated by the end of the year after a final escapade. However, the finding is somewhat old news since the probe also determined that little has likely changed on the planet in the past half-billion years. On the basis of altimetry and gravity data, geophysicist Suzanne Smrekar, of NASA's Jet Propulsion Laboratory in Pasadena, Calif., found evidence of “top loading” and “bottom loading” at several sites.
