(e) Four midcourse corrections which take place at TLI +9, TLI +24, LOI -22 and LOI -5 hours with DV nominally zero (See Table 1-1).

(f) Passive thermal control (PTC) will be conducted during all periods when other activities do not require different attitudes.

(g) LM inspection and housekeeping

(h) LOI1, performed at 75:54:28 GET, ends the TLC phase.

5. 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.
