This 4th of July, NASA will use a spacecraft called Deep Impact to intercept and use part of the spacecraft to collide with the comet Tempel 1.
The purpose of this mission is to collect dust and ice samples from the comet, so that scientist can study the possiblity of comets' "DNA" makeup.
The spacecraft is due to launch in mid-January for intercpetion 4 July.

The spacecraft is called Deep Impact just like the 1998 movie about a comet headed straight for Earth. NASA's goal is to collide a part of the
spacecraft called the "impactor" with Comet Tempel 1. Scientists expect the collision to blast a crater into the comet to analyze the ice, dust and
other primordial stuff hurled out of the pit.
"We'll understand how the comet is put together, its density, its porosity, whether it has a surface crust and underlying ices, whether it's
layered ice, whether it's a wimpy comet or whether it's a rock-hard ice ball. All of these things will become apparent after we smack it."
Formed the same time as the planets 4.5 billion years ago, comets are considered the leftover building blocks of the solar system. When the comets
periodically swing close by the sun, their surfaces heat up and change, and so only their interiors preserve cosmic-origin clues.

I really want to see the footage, hopefully see live feed of this on the 4th of July. Just to see what a comet really does have around, like
portrayed in movies and so forth. Not to mention, what new types of chemical balances, solid mixtures, metals or any other alien materials are to be
found that can not be found here on earth. This could lead to exciting new theories about space and possibly answer some of those daunting questions
that only have theoretical answers.
I don't know, but i think this could be one of those stupid things that NASA comes up with once in a while. That i know the comet is going to be
close enough to Earth that the explosion can be seen..... What i wonder is....how in the world is NASA going to make sure none of the chunks of rock
they blow up comes down our way?......
This reminds me of the other stupid contingency plan that NASA scientists came up with....to use a big enough meteor or asteroid to bump Earth away
from the path of an incoming asteroid, or if the sun starts acting up to use one of these astral bodies to get us farther away from the sun..... To
me that sounds like a very stupid plan....just like blowing up a comet that would be anywhere close to Earth.....well except if the astral body was in
a collision course with Earth or the Moon, i am not sure this is the case here thou.
I looked for the distance that the comet would be from Earth at time of impact. It will be 134 million km, or 0.894 AU, according to the following
link.
The above link is to information about a simliar mission by Spain named after Don Quijote. This was in the news months ago, before NASA announced its
similar mission. And now NASA is launching way ahead of schedule. Is there any significance?
Ha, Ha, I got my name on the CD that they put on the impactor. This is great science as we can not explore space without materials, and it would take
trillions of dollars to get those materials into space from Earth. We need asteroids, and comets.
Don't forget moons. If I could get a business loan for an asteroid mining ship or an ore processing plant on the moon, I'd make billions. The
trick would be to exploit automation, so you'd never have to send people. Use a modular design that basically drops, unfolds, and starts working.
It's a gold mine, pardon the pun. Speaking of gold, is there any on the moon?
WyrdeOne,
I don't know about the Moon, but I remember reading that a 1 mile asteroid would contain enough material to supply the world w/ a 2 yr supply of
nickel and iron and 200 million ounces of precious metals. That would be about 500 or more billion dollars worth of metal if used in orbit(I used 3X
Earth prices as a mark. It could be alot more.)
The Moon could be used for material and to eventually replace all energy production(solar energy stations) leaving oil and coal for hydrocarbon raw
materials.
i don't think it is a good idea to mess around with the Moon, and extracting minerals, or studying comets/asteroids etc that are nowhere close to the
path of the Earth is fine, but this comet is just too close to be messing around with it.
