Gemini Sees Rocky Material on Tempel 1
[link to www.universetoday.com]
Summary - (Jul 7, 2005) As Deep Impact´s
impactor probe smashed into Comet
Tempel 1 this week, every available
observatory, on land and in space was
watching to help gather as much science
as possible from this $333 million
mission. The Gemini North telescope,
located on Hawaii´s Mauna Kea
successfully captured images, before
and after the collision that clearly
show the debris cloud moving off the
comet. They also found evidence that
rocky materials were exposed on the
comet´s surface.

The Gemini North telescope on Mauna Kea
successfully captured the dramatic
fireworks display produced by the
collision of NASA´s Deep Impact probe
with Comet 9P/Tempel 1. Researchers in
two control rooms on Hawaii’s Big Island
(on Mauna Kea and in Hilo) were able to
keep enough composure amid an almost
giddy excitement to perform a
preliminary analysis of the data. They
concluded from the mid-infrared
spectroscopic observations that there
was strong evidence for silicates or
rocky material exposed by the impact.
Little doubt remains that the
unprecedented quality of the Gemini
data will keep astronomers busy for
years.
“The properties of the mid-infrared
light were completely transformed after
impact,” said David Harker of the
University of San Diego,
co-investigator for the research team.
“In addition to brightening by a factor
of about 4, the characteristics of the
mid-infrared light was like a chameleon
and within five minutes of the collision
it looked like an entirely new object.”
Harker’s research partner Chick Woodward of the University of Minnesota
speculated further, “We are possibly
seeing crystalline silicates which
might even be similar to the beach sand
here in Hawaii! This data will keep us
busy trying to figure out the size and
composition of these grains to better
understand the similarities and
differences between the material
contained within comets and other bodies
in the solar system.”
In addition to the spectroscopic
observations, before-and-after images
were also obtained by the Gemini
telescope in thermal infrared light and
can be seen in Figure 1. Gemini
monitored the comet for several weeks
prior to the impact and will continue to
watch it through the end of July.
The Gemini observations were part of a
coordinated effort between the W.M.
Keck, Subaru and Gemini Observatories so
that each could concentrate on
different observations and provide a
complete, complementary “picture” of the
impact. Astronomers anticipate that the
data gathered from the largest and most
sophisticated set of telescopes
positioned to see the impact will add
considerably to our understanding of
comets as dynamic probes of our solar
system’s early evolution some 4.5-5
billion years ago.
The Gemini observations were made using
Michelle, the facility mid-infrared
imager/spectrograph built at the Royal
Observatory of Edinburgh (ROE) in the
UK. The instrument has unique
capabilities in the mid-infrared
especially at Gemini which uses
protected silver coatings on main
mirrors to provide exceptional
performance in the “thermal” or
mid-infrared part of the spectrum.

Its all very electric in nature. Superconducting materials are brothing from 0 Kelvin temps entering the plasmoided inside of the comet at some 33,000 Km/h. |

Meteor showers are being seen up and down the country as Earth passes through debris from a comet
New Zealanders who keep their eyes on the skies in the coming night may be treated to quite a sight.
Meteor showers are being seen up and down the country.
Astronomers say the showers are usual this time of the year, and spokesman for the Palmerston North Astronomical Society Noel Munford says they are caused by comets which have passed by the Earth, leaving debris in their wake.
He says meteor activity is a spectacular instant, where something bursts into prominence in a matter of seconds.
Noel Munford says it is a glorious sight, and is worth wrapping up to go out and have a look.
One Matamata man says he´s never seen anything like the blaze of light he witnessed last night.
Paul Denyer was travelling towards the Kaimai ranges when he saw a meteor burst across the horizon.
He first thought it was an aircraft crashing, but realised it was travelling far too fast.
Mr Denyer says it was an incredible sight, like a huge firework exploding.
He says he has seen meteor showers before, but nothing as big as this. |

"Check this out,Wondering bout a connection here

Note - it says _A_ comet. Nearly all meteor showers are caused by cometary dust trails, but they´re from comets who´s orbits crosses that of the Earth.
Tempel 1´s orbit is outside that of Mars, so we never pass through its trail. There´s no connection to Deep Impact.
Also, sometimes the Earth passes through a thicker, more dusty, part of the trail, which gives a more intense shower with more meteors. That´s almost certainly what´s happened with this shower.

For you folks that might be in the San Francisco Bay area and not on
the ames-releases I pass this to you.
For others further away and not on the list, I pass to you to let you
see where things are going. I will see if I can go over to the
lectures. (in the next building over) If you have an interest or
opinion or something you would like me to look for, let me know.
I suppose the disclaimer would be that I am not a scientist and have
no say in what is presented. I do have ears and eyes though.
Chris McKay has been digging under rocks all over this planet and is
very interested in what we might find on Mars and how we might make
it possible for humans to exist there.
If this interests you as we look at the Moon, Mars and Beyond - stay tuned.
For others, my apologies for two emails in the same day. :>

Hi Kent....check out this thread:
------------------------------
Synopsis:
Alex Jones Caller Gives Comet Tempel 1 Warning
Some guy called in....said he was in the
Aerospace Industry..not NASA. He claims that
Earth is expected to get pelted by an
"unexpected" meteor storm from the debris of
the explosion on the 13th of July. Then, he
said later, not sure how much later, that the
Comet itself would move between the Earth and
Sun and have some kind of effect on the
magnetic protection aspect of the Earth and the
Sun is going to fry us here. Just thought you
might want to know.
--------------------
Dunno, Debris field impact looks more like
effect to Mars

"Fred Whipple - the astronomer who first correctly described comets as "dirty snowballs" - has died aged 97.
He revolutionised the study of comets when in 1950-51 he proposed that they were not "sandbags" but small bodies made of rock, dust and ice. "

The dirty snowball model somehow seeds the Mars
terraform plot. But now the idea seems more
like sandblast, or fireblast---
oops, more damn craters!
