    Hi Joe:
    I was in Houston at the Manned Spacecraft Center in December 1972 for Apollo 17. I remember sitting in on a flight controller change-of-shift press conference and the flight director who had just come off duty saying the ascent stage would be intentionally deorbited (apparently by radio command from the Earth).
    I believe the Ascent Stage impact was going to be observed by the seismometers that the Apollo 17 and earlier Apollo crews had left behind. If I recall, the Ascent Stage impact was of interest because the spent stage had a known mass.
