(See Table 1-1 for burn data). 2. Translunar Coast (Duration 73:10) 2:44 - 75:54 GET After TLI, which places the spacecraft in a free lunar return trajectory, the following major events occur prior to LOI: (a) Transposition, docking and LM ejection, including SIVB photography (b) Separation from SIVB and a CSM evasive maneuver (c) SIVB propulsive venting of propellants (slingshot) (d) Two series of P23 cislunar navigation sightings, star/earth horizon, consisting of five sets at 06:00 GET and five sets at 24:30 GET (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) Pa**ive 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. 3. Lunar Orbit (Duration 59:30) 75:54 - 135:24 GET LOI Day (Duration 25:00) 69:00 - 94:00 (a) LOI1 (b) Photos of targets of opportunity (c) LOI2 (d) Post LOI2 LM entry and inspection. S-Band/UHF B Voice tests will be conducted. (e) Post LOI2 Pseudo landmark tracking (one set of sightings) (See Table 1-4) (f) Rest period of 9 hours DOI and EVA Day (Duration 28:00) 94:00 - 122:00 GET (a) Docked LM activation and checkout (b) Docked landing site landmark sighting (one set of sightings) (See Table 1-3) (c) Undocking and separation (d) DOI thru landing (See Figure 1-3 Powered Descent) (e) LM post touchdown and simulated liftoff (f) Rest period (LM) of 4 hours (g) CSM plane change (h) Rest period (CSM) of 4 hours (i) EVA prep (j) EVA for 2 hours 40 minutes (k) Post EVA (l) Rest period (LM) 4 hours 40 minutes (m) Rest period (CSM) 4 hours 50 minutes Ascent and TEI Day (Duration 25:00) 122:00 - 147:00 GET (a) LM Lift-Off and Insertion (b) LM active rendezvous CSI PC CDH TPI Braking (c) Docking (d) LM jettison (e) TEI (f) Rest Period 4. Lunar Orbit Particulars (Average Values for a 60 x 60 nm orbit) (a) Revolutions start at 180° longitude (b) Revolution duration - 1 hr. 58.2 min. (c) S/C night period duration - 47 min. (d) MSFN coverage per rev. - 72 min. (e) Orbit inclination - 1.25° for July 16, 1969 launch (f) S/C orbital rate - 3°/min. (.05°/sec) (g) Lighting change at fixed ground point - 1°West/Rev. (h) Horizon visibility ± 20° selenocentric angle on the lunar surface (i) One lunar degree on lunar surface is 16.35 nm (j) Site 2 will be visible (3° sun angle) at REV. 7 (k) S/C subvehicle point to horizon 327 nm. 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.
