1
00:00:09,509 --> 00:00:11,094
The engine control is enabled.

2
00:00:11,094 --> 00:00:15,365
Liquid oxygen tanking now at 99%.

3
00:00:15,448 --> 00:00:18,351
And T-minus 45 seconds

4
00:00:20,186 --> 00:00:23,189
liquid oxygen now reported at 100%.

5
00:00:23,189 --> 00:00:27,427
Topping is complete.

6
00:00:27,510 --> 00:00:29,362
And coming up now on 30 seconds,

7
00:00:29,362 --> 00:00:36,653
T-minus 30 seconds and counting

8
00:00:37,721 --> 00:00:41,908
 T-minus 20 seconds and counting.

9
00:00:41,991 --> 00:00:45,178
Battery systems are now reporting
go for launch.

10
00:00:45,261 --> 00:00:47,964
T-minus 15. Locks reported go.

11
00:00:47,964 --> 00:00:54,087
 11, ten, nine, eight, seven, six,

12
00:00:54,170 --> 00:00:58,858
five, four, three, two, we have

13
00:00:58,908 --> 00:01:02,462
main engine start and liftoff.

14
00:01:02,545 --> 00:01:05,515
Liftoff of Delta 189

15
00:01:05,515 --> 00:01:09,035
and the Cosmic Observation
Background Explorer.

16
00:01:09,119 --> 00:01:12,355
And the vehicle has cleared the tower.

17
00:01:15,742 --> 00:01:20,163
Vehicle now moving down range.

18
00:01:20,246 --> 00:01:24,334
Roll  program is in, pitch program is in

19
00:01:24,417 --> 00:01:29,072
Roll program is in.  Vehicle
now moving downrange.

20
00:01:36,346 --> 00:01:40,283
All events continuing

21
00:01:40,283 --> 00:01:44,120
to look good on the Delta vehicle.

22
00:01:45,472 --> 00:01:50,043
Coming up now on one minute into flight,
solid motors continue to burn well.

23
00:01:54,981 --> 00:01:59,619
Vehicle now 8.2 miles
high, 5.3 miles downrange.

24
00:01:59,702 --> 00:02:04,407
Solid motor burn out of all six solids. Other three solids have ignited now.

25
00:02:04,407 --> 00:02:09,462
Velocity 1478 miles per hour.

26
00:02:11,214 --> 00:02:13,049
Engines look good.

27
00:02:13,049 --> 00:02:17,737
The Delta vehicle continuing to perform
nominally.

28
00:02:19,823 --> 00:02:21,691
Altitude now

29
00:02:21,774 --> 00:02:24,744
solid rocket boosters have been jettisoned
on time.

30
00:02:24,744 --> 00:02:28,114
All events continue to look normal.

31
00:02:28,198 --> 00:02:32,185
Attitude disturbances very low level,
very good flight of the vehicle going.

32
00:02:32,185 --> 00:02:36,723
Altitude 14.9 miles, 13.9

33
00:02:36,723 --> 00:02:40,677
miles down range, 2074 miles per hour.

34
00:02:40,760 --> 00:02:43,763
Still a very good flight of Delta COBE.

35
00:02:43,980 --> 00:02:47,550
Coming up now on 2 minutes into the flight

36
00:02:52,488 --> 00:02:55,041
Very smooth first stage performance

37
00:02:55,041 --> 00:02:58,745
right now, second
set of solids have now burned out.

38
00:02:58,828 --> 00:03:01,147
Standing by for jettison,

39
00:03:04,133 --> 00:03:05,668
Solid motor jettison,

40
00:03:05,668 --> 00:03:08,938
and the other three have been jettisoned.

41
00:03:09,022 --> 00:03:13,743
So the delta now
flying on its first stage.

42
00:03:14,878 --> 00:03:17,997
Guidance system reported

43
00:03:18,081 --> 00:03:20,433
supplying good data

44
00:03:26,839 --> 00:03:29,008
Altitude, now

45
00:03:29,008 --> 00:03:32,395
29.9 miles, 49.7 miles

46
00:03:32,395 --> 00:03:37,166
downrange, velocity 4598 miles per hour.

47
00:03:37,250 --> 00:03:39,018
Little bit of

48
00:03:39,018 --> 00:03:42,355
oscillations reported by the vehicle
called Pogo Effect,

49
00:03:42,355 --> 00:03:44,207
however, this is not significant.

50
00:03:44,207 --> 00:03:46,292
Verniers still burning good,

51
00:03:46,292 --> 00:03:49,112
guidance looks good.

52
00:03:49,112 --> 00:03:51,864
We don't see anything
amiss here in the data.

53
00:03:51,864 --> 00:03:54,000
We have a very good flight going here.

54
00:03:59,389 --> 00:04:00,907
Very little to report here;

55
00:04:00,907 --> 00:04:04,027
our data all looks very satisfactory.

56
00:04:04,043 --> 00:04:06,179
The first stage
continues to burn very well.
