launched on September 13 the ma4 flight

2
00:00:16,220 --> 00:00:14,160
was to fly one orbit before the reentry

3
00:00:21,339 --> 00:00:16,230
procedure was to be initiated near the

4
00:00:25,400 --> 00:00:23,839
inside the mercury Control Center the

5
00:00:27,950 --> 00:00:25,410
flight director managed the flight and

00:00:30,980 --> 00:00:27,960
the network operation the Bermuda center

7
00:00:32,990 --> 00:00:30,990
verified the trajectory the tracking and

8
00:00:34,510 --> 00:00:33,000
acquisition facilities of Tagus were

9
00:00:37,340 --> 00:00:34,520
functioning as programmed

10
00:00:39,740 --> 00:00:37,350
one test objective was met early in the

00:00:41,390 --> 00:00:39,750
flight the ability of the Atlas to

12
00:00:45,380 --> 00:00:41,400
release the spacecraft into a proper

13
00:00:46,970 --> 00:00:45,390
orbit as the spacecraft successfully

14
00:00:49,640 --> 00:00:46,980
completed the turnaround and was flying

15
00:00:51,620 --> 00:00:49,650
in the orbital attitude mercury control

16
00:00:54,140 --> 00:00:51,630
personnel observed the various systems

17
00:00:57,140 --> 00:00:54,150
data and verified that all systems were

00:00:58,700 --> 00:00:57,150
go a spacecraft communicator was in

19
00:01:00,820 --> 00:00:58,710
direct voice contact with the tape

20
00:01:03,260 --> 00:01:00,830
recorders aboard the flight vehicle as

21
00:01:06,080 --> 00:01:03,270

00:01:12,529 --> 00:01:08,759
minutes after liftoff all systems were

00:01:25,370 --> 00:01:22,560
minutes after launch the spacecraft

00:01:27,590 --> 00:01:25,380
traveling at more than 17,000 miles per

00:01:30,770 --> 00:01:27,600
hour passed over the Australian tracking

30
00:01:33,260 --> 00:01:30,780

00:01:37,999 --> 00:01:35,219
as the spacecraft approached the west

00:01:40,039 --> 00:01:38,009
coast the re-entry procedure was

34
00:01:42,139 --> 00:01:40,049
initiated and the spacecraft encountered

00:01:45,139 --> 00:01:42,149
the Earth's atmosphere approximately 300

00:01:49,279 --> 00:01:47,520
probable impact point indicator operates

38
00:01:52,760 --> 00:01:49,289
