SDO T-Minus 30 Minutes

At 7:43 AM Phoenix time, the countdown is at T-Minus 30 minutes and counting. The wind is occasionally gusting past the 20 knot upper limit, but at this time, launch control expects the wind levels to be reasonable at some time during the one hour launch window. Launch is scheduled for 8:23 AM Phoenix time (10:23 AM EST).

Yesterday’s attempt was scrubbed due to high winds.

At this time, there are no technical issues. The 45th Weather Squadron will be updating their forecast shortly.

At 8:00 AM Phoenix time, we are 10 minutes away from the built in hold at T-Minus 4 minutes (8:10 AM). At that time, the count will hold until 8:19 AM when the count will resume for launch at 8:23.

At 8:10 AM Phoenix time we are in the hold at T-Minus 4 minutes. The Launch Director has finished polling all systems. All systems are Go at this time.

As seen in the weather images, cloud cover will not be a problem, and wind speed is trending downward.

SDO is on internal power. The SDO Spacecraft is configured for launch. We are still targeting 8:23 for launch. Final poll of all systems is taking place now. All systems are Go.

The countdown has resumed. Wind is within limits.

Launch of the Atlas V with the Solar Dynamics Observatory was on time at 8:23 AM Phoenix time.

At 8:33 AM, we are 10 minutes into the mission. Centaur is burning nominally. The vehicle is 169 miles in altitude, and accelerating at 0.52 G’s and traveling at 13,900 miles per hour.

At 8:37, Centaur is at orbital velocity.

At 8:39, Centaur has finished its 11 minute burn. We are in coast phase for 87 minutes, at which time the second burn will occur.
