This report was published in April, 2015 by the Keck Institute for Space Studies (KISS) Venus Seismology Study Team

KISS stands for Keck Institute of Space Science and is located at Caltech in Pasadena. It's like a "think tank" that works on some of the most difficult planetary exploration problems. How to explore the interior of Venus is one of them.
