SUMMARY: NASA is in the final stage of preparations for the launch of its New Horizons spacecraft, destined to lift off for Pluto in January 2006. If all goes well, New Horizons will blast off January 17, 2006 atop an Atlas V rocket; the launch window extends until February 14, 2006. The spacecraft will make a gravity slingshot past Jupiter in 2007, and arrive at Pluto as early as mid-2015.

I imagine the signals will take a while to reach us from that part of the galaxy.

Lets hope the space craft survives 9 years to make it! I for one am really excited about this mission!

Assuming the probe reaches Pluto in 2015, the one-way light time will be about 4hrs 25min.

How'd you calculate that?

I took that number from the New Horizons Launch Press Kit (http://pluto.jhuapl.edu/images/mainPage/NHLaunchPressKit12_05.pdf) on Pg. 5.

However, if you want to do the calculation yourself, here's what you do:

According to here (http://en.wikipedia.org/wiki/Pluto_(planet)), in July 2015 when New Horizons arrives, Pluto will be about 31.88724AU or 4.77026 x 109 km from Earth. Using the speed of light, 299792.458 km/s and dividing that into the distance we get: 15911.8991 seconds. Divide the number of seconds by 3600/hr and you get 4.41997 hr which works out to be about 4hr 25m.

Waiting 9 long years is too much but it is still better than doing nothing.

Yet i hope M2P2 or electro nuclear rocket will come soon . It is about time.

Well, its our first time to Pluto! So you can't be too disappointed, plus, doesn't that length of time give you some idea about the vast distances in Space? Pluto is one of our neighbours, and yet its almost 10 years away, the rest of the galaxy is literally eons away unfortunately.

It will spring some major surprises I'm sure. We have literally no idea what to expect!
