00:04:40,230 probably will be left in lunar orbit to save weight on the return trip after the 200 00:04:40,230 --> 00:04:40,240 save weight on the return trip after the 201 00:04:40,240 --> 00:04:41,700 save weight on the return trip after the command and service modules are 202 00:04:41,700 --> 00:04:41,710 command and service modules are 203 00:04:41,710 --> 00:04:43,110 command and service modules are thoroughly checked out and all 204 00:04:43,110 --> 00:04:43,120 thoroughly checked out and all 205 00:04:43,120 --> 00:04:45,719 thoroughly checked out and all calculations are confirmed the Apollo 206 00:04:45,719 --> 00:04:45,729 calculations are confirmed the Apollo 207 00:04:45,729 --> 00:04:47,580 calculations are confirmed the Apollo spacecraft will be fired into its 208 00:04:47,580 --> 00:04:47,590 spacecraft will be fired into its 209 00:04:47,590 --> 00:04:50,790 spacecraft will be fired into its trajectory for return to Earth following 210 00:04:50,790 --> 00:04:50,800 trajectory for return to Earth following 211 00:04:50,800 --> 00:04:52,860 trajectory for return to Earth following mid-course Corrections and just before 212 00:04:52,860 --> 00:04:52,870 mid-course Corrections and just before 213 00:04:52,870 --> 00:04:55,200 mid-course Corrections and just before entering the Earth's atmosphere the 214 00:04:55,200 --> 00:04:55,210 entering the Earth's atmosphere the 215 00:04:55,210 --> 00:04:57,150 entering the Earth's atmosphere the service module will be jettisoned and 216 00:04:57,150 --> 00:04:57,160 service module will be jettisoned and 217 00:04:57,160 --> 00:04:59,610 service module will be jettisoned and the command module will be oriented for 218 00:04:59,610 --> 00:04:59,620 the command module will be oriented for 219 00:04:59,620 --> 00:05:08,800 the command module will be oriented for re-entry 220 00:05:08,800 --> 00:05:08,810 221 00:05:08,810 --> 00:05:11,530 at an altitude of approximately 50,000 222 00:05:11,530 --> 00:05:11,540 at an altitude of approximately 50,000 223 00:05:11,540 --> 00:05:14,260 at an altitude of approximately 50,000 feet a drogue parachute will deploy to 224 00:05:14,260 --> 00:05:14,270 feet a drogue parachute will deploy to 225 00:05:14,270 --> 00:05:17,140 feet a drogue parachute will deploy to stabilize the vehicle this will be 226 00:05:17,140 --> 00:05:17,150 stabilize the vehicle this will be 227 00:05:17,150 --> 00:05:18,970 stabilize the vehicle this will be followed shortly by the main parachute 228 00:05:18,970 --> 00:05:18,980 followed shortly by the main parachute 229 00:05:18,980 --> 00:05:21,190 followed shortly by the main parachute system which will gently lower the 230 00:05:21,190 --> 00:05:21,200 system which will gently lower the 231 00:05:21,200 --> 00:05:24,159 system which will gently lower the command module to earth probably on land 232 00:05:24,159 --> 00:05:24,169 command module to earth probably on land 233 00:05:24,169 --> 00:05:27,580 command module to earth probably on land rather than at sea
