Gravity Field of Venus: A Preliminary Analysis

The line-of-sight gravity field for Venus has been mapped by tracking the Pioneer Venus spacecraft in the vicinity of periapsis for a 45° swath of longitude eastward of 294°. There are consistent and systematic variations in the gravity signature from orbit to orbit, attesting to the reality of obse...
