But what is Deep Impact

Apart from a blockbuster movie that had the misfortune to be released at the same time as BA's "favourite film" Armageddon? :oops:

This (http://deepimpact.jpl.nasa.gov/home/index.html) should help.

NASA decided to get the general public interested in space again- so they decided to blow up a comet with the probe "deap impact", for the 4th of July. It will arive this year, and the year after that we will have a spectacular meteor shower again on the 4th of July.

8-[ :P

I'm kinda tired maybe someone else can elaborate

I watched the launch btw :D .

The guy who claims to own that comet has sued NASA, hasn't he?

Yeah, I read in the back of New Scientist magazine that some woman from Russia was suing NASA because blowing up the asteroid disturbed her cosmic balance (or some rubbish like that). The amount she wanted? 11 billion dollars! (apologies if the figure is wrong but it is in the ball park)

The guy who claims he owns Eros is suing NASA for parking fees cause they landed a probe on it :roll: . Also as already stated that crazy nutzoid in Russia tried to sue NASA for damaging Tempel 1 with the Deep Impact Impactor.

Those suits against NASA are hilarious...upsetting one's "cosmic balance," parking fees...wonders never cease. :lol:

Through that NASA link, has anyone entered the Great Comet Crater Contest? A plaque! That's it?? Heck, I'll enter anyway, take a wild guess. :D


Just how big a crater will Deep Impact make on Tempel-1? Will the impactor sink right in to the fluffy comet and leave hardly any mark, or will it slam into a solid surface and dig out a classical crater? Scientists can only guess, because they arenít sure how the comet is put together. The Planetary Society is inviting everybody around the world to make an educated guess as to how big that crater will actually be. If your guess is close enough, you could win a custom-made plaque from Ball Aerospace, who built the Deep Impact Spacecraft. The plaque will be made of the same kind of copper material that makes up the heavy mass of the Impactor, laser-engraved with the mission logo.

Before you guess, you should read more about the Deep Impact mission and learn what kinds of guesses the science team is making about how big the crater will get. Your answer must be in METERS. If you're not used to meters, you may use The Planetary Society's conversion calculator to convert your guess into meters.

Edit: BTW, Sticks, this link here has a very nicely laid out explanation of the Deep Impact mission:

I am probably displaying more ignorance here, but is this wise?

Is there any danger of altering the trajectory of this asteroid to one that will intercept Earth? :-? 8-[ or is that woo-woo thinking?

Yes ...

It WILL Alter it Just Enough, to Make it Hit Newcastle upon Tyne, in 1,000,000,000 Years ...

Just Kidding, It'll Move It, By Less than a Micrometer!

Well, actually it's not an asteroid. Comets and asteroids are different things. But to answer the question (this has been dealt with in other threads), the impactor that will actually hit the comet doesn't have enough mass to be able to influence the trajectory to any measurable extent. If I remember correctly, the impactor weights about 2 tons, and the comet itself weights billions of tons. Someone likened it to a fly smashing into a truck on the highway.

I blame Armageddon for coming out at the same time as Deep Impact. BTW was the mission name, named after that movie?

So no need to get in touch with Bruce Willis's agent :)

No wait ..

That was the other movie #-o :D

ABC News: NASA's Deep Impact Spacecraft Blasts Off (http://abcnews.go.com/US/wireStory?id=410785&CMP=OTC-RSSFeeds0312)


The scientists came up with the Deep Impact name independently of the movie studio, around the same time, neither knowing the other was choosing it, even though some members of NASA's Deep Impact team were consultants on the picture.

Bold mine.

Nope, not even close. The impactor weighs in at 370 kg; (816 lbs) Pretty light actually. Here is a great link for info on the impactor (http://www.nasa.gov/mission_pages/deepimpact/spacecraft/impactor.html)
