Niente da fare si è rialzato il vento, niente lancio per oggi...
Thanks for watching with us today. We'll try again tomorrow. SDO launch window for Feb. 11 is 10:23 to 11:23a ET/3:23 to 4:23p GMT

Centaur Liquid Oxygen Loading Complete
Thu, 11 Feb 2010 02:54:04 PM GMT+0100

The Centaur upper stage's liquid oxygen level has reached 95 percent. At this point, the "topping" process will pump small amounts of the propellant into the tank to replace any that evaporates during the rest of the countdown.

Alla Nasa sono ottimisti, venti al di sotto dei 20 nodi, e le nudi non dovrebbeo costituire un problema.

Spacecraft Test Team "Go" for Launch
Thu, 11 Feb 2010 03:07:27 PM GMT+0100

The Solar Dynamics Observatory test team reports there are no problems with the spacecraft, and with the exception of the switch to internal power, SDO is ready to fly. The spacecraft will change to internal power after launch managers commit to a launch time. Right now, the team continues to aim for the opening of today's launch window at 10:23 a.m.

Centaur Liquid Hydrogen Tanking Under Way
Thu, 11 Feb 2010 03:12:23 PM UTC+0100
The team is beginning to load 12,680 gallons of liquid hydrogen into the Centaur upper stage. Atlas V liquid oxygen loading just passed 50 percent.

Flight Termination System Checks Complete
Thu, 11 Feb 2010 03:47:32 PM GMT+0100

Range Safety has completed their final set of communication checks between range antennas and the Atlas V vehicle. That's the communication loop the rocket's flight termination system would use to destroy the rocket if it veered dangerously off course.

Winds have increased a bit, occasionally bumping up above the 20-knot limit, which is exactly what forecasters predicted might happen. We're still expected to find a time during the launch window when winds stay within limits.

Liftoff of NASA's Newest Solar Observatory!
Thu, 11 Feb 2010 04:23:10 PM GMT+0100

NASA's Solar Dynamics Observatory is on its way into space, seeking a vantage point in orbit where it will examine our sun in more detail than ever before. The Atlas V carrying the SDO spacecraft is thundering into the Florida sky on 863,000 pounds of thrust. The booster's RD-180 engine will burn for about four minutes before the booster burns out and separates from the Centaur upper stage.
