Notes
Impact times are Earth received times, approximately 1.3 seconds later than real time on the Moon.
SIVB coordinate data are from Lunar Reconnaissance Orbiter images of impact sites and
Wagner et al., Icarus 283, pp. 92-103 (2017) using planetocentric Mean Earth/Polar
Axis Lunar Reference System - DE421 ephemeris.
The SIVB is the Saturn upper stage which was targeted towards the Moon after separation from Apollo.
The Apollo 11 SIVB was injected into heliocentric orbit, the Apollo 12 SIVB into Earth orbit.
The Apollo 11 and 16 LM's were jettisoned into (temporary) lunar orbits.
The Apollo 13 LM re-entered Earth's atmosphere on 17 April 1970.
*A malfunction resulted in premature loss of tracking data for the Apollo 16 SIVB.
Time and impact energy are estimates based on interpretation of seismic data.
Uncertainty in the Apollo 16 impact time is about 4 seconds.
(The impact location estimated based on tracking prior to signal loss was 2.24 N, 24.49 W)
