Transearth Coast and Entry (Duration 59:39) 131:52 - 195:03 GET Transearth coast begins with TEI at 135:24:34 GET and consists of the following major events: (a) Three midcourse corrections are scheduled at TEI +15, EI -23 and EI -3 hours with DV nominally zero. (b) CM/SM separation takes place at 194:51 GET and Entry Interface occurs at 195:03 GET. (c) Splashdown will occur in the Pacific Ocean at a longitude of about 172.4° West at 195:17 GET. This will occur approximately 25 minutes prior to sunrise local time. 1 - 3
