I thought it was time, with the Atlas V about to roll out - for a new thread for NH for the launch etc.

Someone asked over at the HZ just how NH can go so fast, this was my reply....

QUOTE
How do you get a spacecraft to Jupiter in under a year? Easy. Make it very very light, and put it on a very very big rocket. The config of Atlas V rocket being used to launch NH (551 - 5m fairing, 5 solids, and one engine on the Centaur stage ) would typically put 8,670kg into GTO or 20,520 into LEO.
New Horizons is 478kg, and it's Star 48B 3rd stage is 2,137kg - so instead of hauling 20 tons, this vehicle is hauling about 2.5 tons thus you get a HUGE velocity out of it. AND, once it's done that, you have the final kick of the 48B, 591 thousand kgs-s (thus accelerating is all a further 3.5 - 4km/s ball park speed, if my maths is right)
At launch - the vehicle is 573,160kg. NH is 0.083% of it.
Imagine the Apollo entry capsule on top of a Saturn V...tiny tiny tiny... that was 5,800 kg on a 3,038,500kg rocket - 0.191% - more than double that percentage of NH. The cutaway's are almost comical, with this tiny gold-clad box on an enormous vehicle.
Basically - it's a LOT of rocket, and not a lot of payload.
For comparison, look how much fuss was made of Stardust that entered so quickly. It took >16 hrs to get from the distance of the moon to Utah. NH makes that journey in 9 hours smile.gif
One thing the NH mission is not short of, is superlatives.


I'm not one for good luck charms (although I'll eat peanuts during a Martian EDL with the best of them), but this mission has been so long in coming, that it deserves every ounce of luck it can have - the best, most accurate launch possible, the cleanest checkout, and incident free cruise to Jupiter.

Goodluck and Godspeed little one, we're with you every step of the way.

Doug
PS - Alan, you're a credit to your field, spending so much time answering questions and writing the PI Perspectives, it's been a hell of a journey!

Probably an alumin(i)um/lithium alloy.

The first stage tank is Copper Anodised Aluminium.

" Anodising successfully combines science with nature to create one of nature's best metal finishes.

It is an electrochemical process that thickens and toughens the naturally occurring protective oxide. The resulting finish, depending on the process, is the second hardest substance known to man, second only to diamond"

"Copper" anodized aluminum? I understand the anodizing process leaves a bonded coating of aluminum oxide. Is copper used as a descriptive adjective here, or is there actually copper involved?
