00:00:01,090 --> 00:00:08,970
\h        George Diller/SDO Launch Commentator:  T minus 10... nine... eight... seven... six... five... four... "go" for main engine start...

2
00:00:08,970 --> 00:00:13,810
\h        three... two... one... zero... and ignition...

3
00:00:13,810 --> 00:00:22,410
\h        and liftoff of a the Atlas V with the Solar Dynamics Observatory, learning why our star is changing our lives.

4
00:00:22,410 --> 00:01:01,250
\h        (Rumbling)

5
00:01:01,250 --> 00:01:09,010
\h        Rob Gagnon/Launch Vehicle Telemetry Manager:  coming up on going into closed loop control and Atlas PU.

6
00:01:09,010 --> 00:01:13,650
\h        And return to closed loop control on Atlas utilization.

7
00:01:13,650 --> 00:01:20,350
\h        Pressure's continuing to look good. Mission operating pressure's continue to look good.

8
00:01:20,350 --> 00:01:35,700
\h        Flight control data is smooth as expected for this portion of atmospheric flight. Coming up on Mach 1.

9
00:01:35,700 --> 00:01:45,840
\h        And the vehicle is now supersonic. Approaching max dynamic pressure. Everything is looking good.

10
00:01:45,840 --> 00:02:00,650
\h        And we are hitting Max Q. VU is controlling as expected. Operating as expected. Everything looking good.
