I had entered orbit around the moon and began to adjust it to about a 100-km altitude circular. After burning retrograde to lower periapsis to some 90-odd km, I continued around towards periapsis to circularize. The Orbit MFD showed a reasonable elliptical orbit that seemed to agree with the listed parameters.
About 5 or 10 minutes out from Periapsis, the terrain whizzing by showed that something was badly wrong. PeA was still listed as about 97 km, but current altitude was 27 km and going down fast.
What kind of geometry allows me to fly below my own periapsis? This is the first time this has happened to me in several lunar landings. I felt puzzled and cheated sitting on the fresh crater rim with the DGIV parts scattered about.
