Atlas 5 Rocket Set to Launch Pluto Probe
tmerrill writes "An unprecedented mission to the outer edges of our solar system is set to launch in 4 days, despite a launch delay. From the article: 'NASA's first spacecraft to visit the planet Pluto is set to launch no earlier than Jan. 17 atop an Atlas 5 rocket on a decade-long trip to the fringe of the Solar System ... In order to reach Pluto by 2015, the $650 million New Horizons mission must lift off this month in order to swing by Jupiter for a gravity boost. The probe's 35-day launch window, however, stretches until Feb. 14. The launch window opens on Jan. 11. Inspections of the probe's Atlas 5 booster prompted mission managers to push their launch target to no earlier than Jan. 17, NASA officials said.'" The New York Times has details as well.
I should start by saying that there's a wealth of information out online about Lockheed Martin's Atlas V.
The article gave a link to www.space.com but if you want the source of this information, you should go to Spaceflight Now for their informative diagrams. You can get an idea of how the vehicle actually breaks apart to deliver its payload. You can read about how they plan to retrieve the boosters from the ocean, the simulated views of onboard cameras, or previous Atlas launches. This site contains for more information than the one listed in the article.
If you're interested in payload sizes, check out Wikipedia's entries on this topic or the International Launch Service's documentation of preparation for Atlas V launches.

"Truth is much too complicated to allow anything but approximations"
Atlas V generates a peak 4 meganewton thrust. The old Saturn V(apollo booster) generated up to 35MN, and could deliver up to 120,000 pounds into low Earth orbit.
Sigh... were the Moon landings a technological feat, never to be duplicated?
..........FULL STOP.
This probe was cancelled and reinstated multiple times. One congress committe would cancel it and the next one would reinstate it. One reason it finally went thru is that Pluto's atmosphere will soon freeze into nitrogen snow when it gets further from the sun because of Pluto's lopsided orbit. There will not be an opportunity to see the snow turn (melt) back into an atmosphere for something like 250 years from now. Thus, it is now or never. Other planets and moons can wait, but Pluto's atmosphere cannot.
