Scientists Perceive NASA Bias Against Venus, Scientific American

"Venus would seem to be a tempting destination for planetary probes: conveniently close, and an extreme laboratory for atmospheric processes familiar on Earth. So why won't NASA send a mission there? That was the frustrated question coming from scientists at the annual meeting of NASA's Venus Exploration Analysis Group (VEXAG) near Washington, D.C., on August 30-31. They perceive an agency bias against Venus, a planet that hasn't seen a U.S. mission since the Magellan probe radar-mapped its shrouded surface in the early 1990s, and which won't see one any time soon, after NASA this year rejected a bumper crop of Venus proposals."
