Comet mission set for DEEP IMPACT !!!!! |
Comet mission set for deep impact
By Paul Rincon
BBC News science reporter
The US Deep Impact spacecraft is set to slam a washing machine-sized
projectile into a comet, to reveal what's inside.
The main spacecraft will release its 372kg "impactor" into the path of
Comet Tempel 1 on Sunday, for an expected collision on Monday morning.
By studying the comet's interior, scientists aim to learn more about
the formation of our Solar System and the chemical building blocks of
life.
Its mission will be short-lived but is certain to be spectacular.
Spacecraft instruments and ground-based telescopes will record the
event, as a hole the size of a football stadium is blasted in the
comet.
Like any good geologist would, we want to hit it with a hammer and see
what's inside
Jessica Sunshine, mission scientist.
The cosmic fireworks are scheduled for 0552 GMT on 4 July - American
Independence Day.
Deep Impact, the spacecraft which carries and ejects the impactor will
take pictures and gather data from the collision and its aftermath, 133
million kilometres (83 million miles) from Earth.
Comets are porous balls of ice and rock hailing from the frigid outer
boundaries of our Solar System. Periodically, some journey inwards,
looping around the Sun.
Like other comets, Tempel 1 contains "pristine" material unchanged
since the the Universe formed. This is hidden beneath an outer crust.
"These materials have not seen the light of day for 4.6 billion years,"
mission scientist Jessica Sunshine told reporters at a news conference
in Pasadena, California. But scientists still know very little about
the composition of this material.
"Like any good geologist would, we want to hit it (Tempel 1) with a
hammer and see what's inside," Dr Sunshine added.
The impactor itself will shatter as the comet crashes into it at 37,000
km/h (23,000 mph), but an onboard camera will record the approach in
the last minutes before collision.
Cometary impacts early in Earth history are thought to have first
brought water to our planet.
They might also have seeded it with the chemical building blocks
required for life. "We want to find out what those materials were,"
explained Rick Grammier, Deep Impact project manager.
World watches
Mr Grammier likened the mission to "a bullet trying to hit another
bullet with a third bullet in the right place at the right time".
Despite the complexities, team members are confident they won't miss.
Mission manager Dave Spencer said: "We've got good navigation, a good
idea of the comet's trajectory and we've been correcting for that all
along.
"We're well prepared to position ourselves for this train that's going
to run over us."
The impact is expected to excavate a crater more than 25m deep and 100m
across, ejecting ice, dust and gas and exposing pristine material.
The Hubble, Chandra, Spitzer and XMM Newton space observatories will be
trained on Tempel 1 for the collision, as will ground-based telescopes
worldwide.
Deflecting danger
The mission could inform strategies for deflecting a comet, should one
threaten to strike Earth.
"If you are worried about defending Earth from possible impactors, it's
a whole lot easier to change the course of something if you know what
it is you're changing the course of," said Dr Mike A'Hearn, Deep Impact
principal investigator.
This week, astronomers got a preview of the pyrotechnics to come when
Tempel 1's nucleus released a short-lived blizzard of particles and
gas.
These outbursts seem to occur as comets heat up approaching the Sun.

Don.t believe everything you hear from NASA / JPL:
The impact was so GREAT, that the change of direction of the Asteroid can actually be
seen in the last few frames of the asteroid impact from both the Observer and Hubble.
(these frames have been extremely limit in there distribution.)
I have seen the ones from the Observer, and the projectile path of the Asteroid does
change !!!
This may not be of concern, but it is a concern , "None the Less".

Whatever.
Instead, believe the global astronomical community, they are the ones
that track the movements of celestial objects like comets.
NASA only maintains a database, but not the only one, on Near Earth
Objects and it's not possible to fudge the results, astronomers globally
would be all over in hours.
JPL is concerned only with space probes not pure astronomy (except as an
end user for navigation.)
The impact was so GREAT,
Compared to? Hmmm, now what was the mass of the probe v the mass of the
comet again?
that the change of direction of the Asteroid can actually be

Balderdash.
No alteration of the trajectory of the *comet* could be demonstrated in
single frame images taken from a fast moving spacecraft, it would
require detailed astrometry of the motion of the object over some time
to determine what (if any) effect the impact had on the orbit. Hint:
Think not much given the difference in mass. The comet masses on the
order of several million tons and is couple of km in diameter.
The probe weighed in under 900lbs and was the size of a washing machine.
Consider also that the probe was basically 'run down' by the comet, most
of the velocity (and therefore inertia) was the comet, not the probe.
Think of the QE2 hitting an icecube in mid ocean.
The impact *looked* impressive, but to make any noticeable difference to
the orbit of the comet in question would require impact energies several
orders of magnitude higher than that created by the impactor.
(these frames have been extremely limit in there distribution.)
Oh? Sure about that?
I have seen the ones from the Observer, and the projectile path of the Asteroid does

Codswallop. Tracking the motion of minor planetary objects sufficient
to generate orbital data for them involves taking pictures of them using
the stellar background as a reference from several different locations
and the motion plotted over several days or even weeks before a good
approximation of the orbit can be made. It would take some weeks (at
least) to see if there were any discernible change in the orbit of the
object. Given that the amount of energy needed to change the orbit by
an amount greater than the normal amount of error incurred during the
astrometric data capture and reduction process would be some orders of
magnitude greater than those resulting from the impact, it's highly
unlikely a change in the orbit will even be detectable, it would be
literally too small to notice (or matter).
This may not be of concern, but it is a concern , "None the Less".
Really? Why? Please provide proof with your answer. Show all working
and astrometric data and the the methodology used to calculate any
alleged change in the orbit of the comet allegedly induced by the impact
and clearly state and demonstrate why this is a cause for concern.
Alternatively, sit down and shut up.

Sorry 'friend', but the direction of the 'projectile' (asteroid) changed direction
right before the 'Observer's" camera. I have only seen this video footage once on a
none JPL / NASA controlled channel, and have not seen this portion of the video since.
But, the asteroid mass moves away from the 'stationary' Observer craft at a high rate
of speed (just after the Major dust kick-up of impact of the lander (within two
minutes of touchdown).
This asteroid has changed its path and NASA will only admit this when particles of
this asteroid are on immanent path of an Earth collision (and even then, there will be
a "Cover-Up")

Then you probably imagined things. Not really a surprise, is it?
But, the asteroid mass moves away from the 'stationary' Observer craft at a high rate

This asteroid has changed its path and NASA will only admit this when particles of

And all of the amateur astronomers in the world (millions of us), all
of whom can image objects far better than in the past 10 years, and
many with the ability to calculate an ephemeris, and all of whom would
like to be famous for making such a discovery, will be part of the
sekrit coverup, right?
Think critically for a second, chicken little.

Your suggestion that the comet's orbit was measurably altered by the
impactor is mathematically demonstrable to be incorrect.
What's your point? You are comparing apples with street lights.

Well there wasn't millions of amateur detectors who could back you up.
You had a 50% chance of being right.
You are wrong about the comet. Laughably so.

100%. It will not.

No you saw an apparent motion that you *chose* to interpret as a change
of course.
Just like people that believe they have seen Aliens, you cannot convince me otherwise,
That would be a failure on your part to perceive reality, nothing more.
that the trajectory of the comet did not change. I saw it with my own eyes !!!
No, you misinterpreted something you saw. Mathematics do not lie, but
your senses will, frequently and enthusiastically.
Just My Thoughts (and I will take these ones to my grave)!!!
You should treat your thoughts to some study of astronomy and
particularly astrometry, which is the science of tracking celestial
objects using photgraphic techniques in conjunction with telescopes.
This will yield sufficient data to calculate orbits, which will clearly
demonstrate that your *perception* is false.

Since you're the only one with a reasonable response (and the only one that realized
the Alien comment was only a comparison.), I will respond back.
After giving it much thought (and browsing the Astronomical Community); maybe I
mis-interpreted the 'observer' breaking out of its current orbit as the asteroid
actually being the changing projectile. This makes perfect sense to me, and it
satisfies the fact that the asteroid is still perceived to be on course.
And, it explains what I saw !!!

That seems likely. Your senses automatically assume that your point of
view is stationary and that all motion is relative to that 'fixed'
reference, when in fact, particularly in this case, the viewpoint was
travelling at high velocity relative to both the comet and the Earth.
This means you saw an *apparent* motion rather than an *actual* motion
of the comet.
Even from observatories here, you must allow for the motion of the
Earth, in its orbit around the Sun, and it's rotation as well as the
motion of the entire system through space. To say this is complex is
a huge understatement, there are an enormous number of variables that
must be reduced to give a true rendition of an orbit.
And, it explains what I saw !!!
Yes, it certainly could.
I am pleased that you have become enlightened by this. My only wish was
that you learn more about it, enough to understand that your
oversimplistic observation was causing you to make an erroneous
conclusion.
You were able to cast aside your preconceived notion and look into the
science and reality enough to see what really happened. That's impressive.
Well done that man.

Actually, I had already assumed the 'Observer' and the 'Impact Unit' would have no
relevance to the Earth or anything else out there that has reference to our Stellar
System, that is why I negated that possibility completely [as we are talking 'Deep
Space'] I had already factored that into the 'movement'.
That is why I had already Ruled-Out the possibility of 'persuasiveness' from the
impact of the 'Impact Unit' on the 'Observer' [as this would be none existence in Deep
Space] !
My MAIN concern is Two Fold, why did (I See) a drifting of the asteroid from the
'Observer' (which I think has been explained), and why has this 'footage' been only
shown ONCE (which still requires an explanation !!!)

Are you talking about an asteroid or comet tempel?

Ok. Unfortunately you seem to be the only one who did, and the
ephemeris of the comet has not changed. It's exactly where it's
supposed to be, so it must NOT have changed it's trajectory in such a
way that you saw it.
That suggests you are mistaken.
Are you saying you believe everything you think you see with your

Just tell him, Wally that as a result of the Impact it took a century
off the life of the comet :}. He should be happy with that, saw it
move indeed more like just saw it get absorbed.
Besides they saw evidence of other impacts, no doubt Aliens have also
used this comet for their weird experiments too.

Logical. There are still a few 'unexplained' things each year, but for
some reason, all video footage is of truly dreadful quality. Funny
