1
00:00:00,000 --> 00:00:02,440
And
so here we go.

2
00:00:02,580 --> 00:00:16,360
T-minus 10 seconds, nine, eight, seven, six,
five four, three, two, one, zero … and liftoff

3
00:00:16,360 --> 00:00:22,420
of our Solar Orbiter, an international collaboration
to give us new images and a better understanding

4
00:00:22,520 --> 00:00:25,100
of our life-giving star.

5
00:00:31,320 --> 00:00:35,580
Now you hear the voice of Patrick Moore,
ULA’s launch commentator.

6
00:00:35,620 --> 00:00:42,260
ULA Launch Commentator Patrick Moore: Now
25 seconds into flight; pressure on the SRB

7
00:00:42,260 --> 00:00:44,050
looks good.

8
00:00:44,050 --> 00:00:45,050
Inaudible.

9
00:00:45,050 --> 00:00:47,260
Good report so far.

10
00:00:47,260 --> 00:00:51,900
Atlas V beginning to … And at 35 seconds in, vehicle is completing
the pitch over maneuver.

11
00:00:51,900 --> 00:00:54,620
Now 41 seconds into flight,

12
00:00:54,620 --> 00:01:00,200
Forty-five seconds into flight — everything
is looking good.

13
00:01:00,200 --> 00:01:04,830
We heard that the RD-180 engine was
operational … RD-180 throttling down as

14
00:01:04,830 --> 00:01:07,960
expected; engine response looks good.

15
00:01:07,980 --> 00:01:11,900
Now they’re going to pull those engines
down for just a little bit as we anticipate

16
00:01:11,960 --> 00:01:12,960
Max-Q.

17
00:01:20,920 --> 00:01:24,920
Vehicle is now passing through Max-Q,
maximum dynamic pressure.

18
00:01:25,700 --> 00:01:29,820
Maximum dynamic pressure is the period of
maximum mechanical stress on the rocket because
