    Nuclear rocket gets White House approval

    The White House has given NASA the go-ahead on plans to launch a plutonium-powered spacecraft on the world's first mission to Pluto, an official said Monday.

    The green light came when John Marburger, who is director of the White House Office of Science and Technology Policy, signed final launch approval papers earlier this month.

    36 Protestors turn up to oppose New Horizions

    Not so good, they even think that this has something to do with weapons development

    Indeed. There is a risk, but a very small risk. Has a swing-by maneuvre ever gone wrong in the past? The nuclear material is built to withstand launch failure, so that's less of an issue.

    If an airliner crashes into a building, hundreds of people not involved with the flight can be killed. I'm surprised that this has not happened a lot. It's not like this launch is the only action putting uninvolved people at risk. It's a good thing we're aware of the risk and take it into account, but as far as I'm familiar with the technology, it is acceptable.

    If we'd exchange exploration for optimal safety all the time we would not be humans. Looking at where we are now, this behaviour apparently works. And it does make us special and gives rise to good fun from time to time .

    Its getting exciting now. Only a decade or so before we get to see Pluto! I bet it will be different to most predictions. They always are!

    When reading history books on how long it took to reach America during the explorer's travels, I feel this might repeat itself with these travels.

    "only a decade or so before we get to see Pluto" might sound very strange in the far future.


    I've put on the piece of music that makes me think most of planetary exploration: Mike Oldfield's Ommadawn, part 2 starting from 10.09.

    The nearest example to a failed swing-by maneuver would be the error in Mars Climate Observer's trajectory calculations that had it plowing into the atmosphere rather than skimming above it. However, this was more a failure due to lack of verification than anything else - if it were Earth and a plutonium-bearing spacecraft, I'm sure that the extra checks would have been done.

    I would assume so. That' what I mean with "It's a good thing we're aware of the risk and take it into account".

    As long as they're kept awake and know why they need to pay extra attention, this is an acceptable risk IMO.

    I haven't seen an actual launch time yet, just sometime once the window opens. Has a specific time been decided?

    I looked on the New Horizons website and answered my question.
    1:24 PM EST on the 17th, right when the window opens.

    The only "swing-by" for this mission involves Jupiter. That's if launch is during the first 17 days of the mission window. After that, there are 12 remaining days for a direct-to-Pluto launch. Details on the Jupiter encounter/mission profile may be found here.*

    BTW, TTBOMK, this is the first launch of an Atlas V 551 (5-meter fairing, 5 SRBs, 1 engine Centaur).

    *How 17 plus 12 days equals 35 days I'm not sure. Maybe there's a 6 day "no launch" window in between.

    I think they've tweaked some of the numbers to reflect the slip in the earliest launch date.

    The original full launch window was January 11-February 14, a 35-day window. It needs to launch by February 2 to get the Jupiter swingby assist (and let's hope it does because it means the spacecraft reaches Pluto three years sooner).

    With the current earliest launch date as January 17, the Jupiter-assist launch window is down to the aforementioned 17 days.

    What time is the launch? Will CNN or any of the 24hr. news networks cover it?

    Here's your NASA TV schedule.

    As for the network and cable news folks, I guess it all depends on what Paris Hilton, Martha Stewart, et al are doing during that particular time frame.

    OK, so we're now into the "6-day no launch due to slippage" part of the launch window. Got it.

    Same here re the "Jupiter effect": wouldn't want to have increased senility interfere with comprehending the culmination of the mission.

    Yes, I would much rather know about how Martha's ankle bracelet tracking device is chaffing her skin. Or Paris's latest nitwit reality show.

    Simultaneously, of course, there is "real" work to do. The launch vehicle is undergoing final closeouts on the launch pad at Cape Canaveral Air Force Station, Florida, and the final NASA Flight Planning Board has been held. Thursday will be the NASA Flight Readiness Review, which will be followed Friday by launch team communications checks, and then Sunday by the Launch Readiness Review. It's hard to believe, but in less than a week New Horizons should be millions of kilometers away from Earth, screaming its way outbound for the Kuiper Belt.

    Anyone going to program a Macintosh widget for NH after it launches?
