[i]...launch occurred 2 hours 40 minutes late at a ground elapsed time of 11, of a Central Standard Time rather, 11:33 PM. As a result of the late launch-time the translunar injection, that's up through translunar injection, also slipped 2 hours, 40 minutes. We would expect that the translunar injection which is targeted to make up the difference will get us back on the nominal flight plan time by the time the spacecraft arrives at the Moon. In other words, arrival time at the Moon would be at the same Central Standard Time as called for in the Flight Plan at about 1:49 PM Central Standard Time, December 10. But, the Ground Elapsed Time would be about 2 hours, 40 minutes earlier than that provided for in the Flight Plan, the arrival being at about 86 hours, 14 minutes ground elapsed time. The 2 hour, 40 minute difference being accounted for in a speedier arrival time at the Moon, a translunar injection burn being targeted just slightly longer than would have been the case in a normal launch. The spacecraft getting to the Moon in a total elapsed time 2 hours 40 minutes less, in effect, making up for lost time from the late launch. In order to get the flight plan back in agreement with the ground elapsed time the GET, or ground elapsed clock, will simply be moved ahead 2 hours, 40 minutes between now and the time spacecraft arrives at the Moon. So, that by the time Apollo 17 is inserted into Lunar Orbit, the GET will once again agree with the flight plan GET and of course, the Central Standard Time of arrival will be the same as was originally planned by virtue of a speedier trip time.[/i]
