Delta IV Heavy DSP-23 launch

To respond to 123NOTIT...your comment was absurd. Every rocket that uses Liquid Hydrogen and Oxygen vents hydrogen gas. Thats why man rated rockets use elements to "burn off" excess Hydrogen. Needless to say, the astronauts are safe in an air tight capsule on top. They are going into space and nothing outside the rocket will harm them. As for the Atlas using Russian engines...what ????

well thats pretty slow. I can't imagine how heavy it is then...

"A study by the Aerospace Corporation, conducted at the request of NASA to disprove the viability of an option to switch Orion to an alternative Evolved Expendable Launch Vehicle (EELV), has found both the Atlas V Heavy and Delta IV Heavy are capable of launching Orion on both ISS and Lunar missions. Meanwhile, former NASA administrator Mike Griffin once again dismissed all alternatives to Ares I as unviable, due to the efforts already spent on Constellation.

The delta V heavy can actually carry more cargo to LEO than the shuttle. It can accommodate the same fairing size as well.  Maybe after the shuttle retires they can use these to deliver new components to the ISS.

That is one underpowered LV. T/W|lo = 1.16. Ouch...

24 seconds to clear the launch pad, thats one heavy mother...

Oh man, can you imagine when there are six of these RS-68s on Ares V?? I hope they figure out a way to mitigate that fireball. I'd like my Ares V non-crispy, please. :)

AHH! it was so amazing...
