Lunar Prospector read 53 minutes earlier. This simple solid-state recorder ensured that all data collected during communications blackout periods would be received, providing the blackout was not longer than 53 minutes. The probe also carried a small amount of the remains of Eugene Shoemaker (April 28, 1928 – July 18, 1997), astronomer and co-discoverer of Comet Shoemaker-Levy 9, to the Moon for a space burial. Following launch on January 7, 1998 UT (6 January EST) aboard a four-stage Athena II rocket, "Lunar Prospector" had a 105-hour cruise to the Moon.
