They are launching this rocket at 1:24pm EST. Its powered by 24 POUNDS of plutonium, and they are launching it about 123 miles away.

They say if it blows up in the air, it'll spread plutonium waste over a wide swath over central florida (Orlando, Lakeland (me) Tampa)...

So if something goes wrong, I'll GLOW! (Choc too!) Choc-glow! lol..

Its gonna be a fast launch craft! It'll be past the moon in 9 hrs and to Pluto in 2015! That is FAST!

Would it not be awesome if they could park a Hubble quality telescope near pluto and see if we can find more planets? They said they have found 2 other planetary bodies, yet small, or smaller than Pluto, and are not 'official' planets. (Sedna ect..)

Ah, astrophysics...it makes me feel warm and fuzzy.

To be fair...a Hubble-esque telescope orbiting Pluto wouldn't really have that much an advantage over the current Hubble...'tis a shame they're not making a repair run for that thing...it won't live to see this probe at Pluto.

Thankfully, ground-based telescopes are catching up.

Wasn't Cassini nuclear-powered, also? The probe they launched back in...erm...'98 maybe? I remember it from childhood, but would have to look up the date.

Stupid CNN and their coverage of the Golden Globes instead of this probe :(

Hopefully, they'll learn a good deal about the composition of Pluto...any idea what probes they're sending? Will there be a lander? Surely an orbital module that'll map the planet, as that's just a prerequisite.

Needless to say, I'm somewhat excited.

Go to www.nasa.gov and watch it live on free NASA TV! [img]smile.gif[/img] I am!

From CNN, just a moment ago, about the probe:

"Scientists hope to determine, once and for all, how planets and the universe were formed."

HA! I wish it was that simple, that we could just send a probe to Pluto and figure it all out! LOL

[img]smile.gif[/img] yeh, they think the Kuiper belt is the remains of what formed our planets. Hell, for all we know, if could have been a planet that got hit by a 'rogue planet' and smashed into it. It's happened before in other systems they say, so who knows WHAT the Kuiper belt holds...

Windy in your neighborhood also, Z? They just gave the entire country your weather, with 30 mph winds...

I hope that dies down by 12:45. I'd like to see the launch, but I've got an appointment of sorts at the library at that time...

Yeh, its really windy here.. I think they may scrub it for today. (Hope not though) :(

<font color = lightgreen>I'm surprised they're not using an updated version of the ionic drive that is still accelerating one satellite after several years. Currently, it is the fastest-velocity man-made object to date. </font>

I think that the current ion drives are solar powered. There isn't a whole lot of solar energy out by pluto.

There was a NASA effort to use nuclear power to run an ion engine, named Project Prometheus, however funding has all but disapeared.

Cassini, Voyager 1&2, Pioneer 10&11, 6 Apollo missions, and several other NASA projects have used radioactive decay for power. The Martian Rovers used a similar technology to keep themselves warm

I can't wait till they finally stick a proper nuclear reactor on one of these things. Then our spacecraft will be able to do remarkable things like stopping or turning around.

Great news about the mission though [img]smile.gif[/img]

"Radioactive decay," eh. Sounds like I ought to have known that they weren't, as Shamrock said, proper nuclear reactors. I'll have to do some research!

You typically can't pick up enough energy from a solar cell from say Jupiter on out.

It appears that they'll launch it today instead.

Yeh, the Decay is what causes heat, inturn creating power for the batteries.

I wonder if they ever sent a probe to yer anus? I hope not.


[img]graemlins/hehe.gif[/img] yeh.. deja vu

I don't think we realise quite how fast.

If it arrives on 16th Jan 2015, in 78840 hours, and Pluto is at closest 2,700,000,000 miles away, then that rocket is doing:
34246 miles per hour
571 miles per minute
9.5 miles per second

wow.

Distance to the sun = speed of light x 8 min
= ( 3 x 10 ^8 ) x ( 8 x 60 )
= 1.44 x 10 ^ 11

Angular velocity = 2 x pi / seconds in a year
= very small

Speed of earth = 30000 metres / sec (very approximate)
= 18 miles / sec

Everything on such a scale is damn impressive...

Wouldn't worry about the fallout, Z. It is reckoned that to be killed by a 'dirty bomb' (same principle as a radioactive spaceship blowing up) you'd have to be in the area for a good few score years.

smokin!! wow, I was unaware of a launch, I gues sI should come out into the day light once in a while :D

wow. </font>[/QUOTE]To put that in perspective, a jet flying across the atlantic ocean flies at approximately 550 mph, and takes 8 hours or so from Detroit to Paris. In this critter, it'd be there in about 8 minutes....

The Concord only went about 2000 MPH or thereabouts... still far, far slower.

W.O.W.

It went off today! See ya in 9 years [img]smile.gif[/img] [img]smile.gif[/img]

I miss hearing the shuttles sonic boom... wonder when they will launch again? I mean, the boom is so loud, I think a semi hit the house once. It goes "BOOM,BOOOOOOM" Even freakier at NIGHT when you don't expect it. hehe

I always wondered why the shuttle has 2 booms? Anybody?
