Brief Summary
Crew Earth Observations - International Polar Year (CEO-IPY) is an
international collaboration of scientists for the observation and
exploration of Earth?s Polar Regions from 2007 to 2009. International
Space Station crewmembers will photograph polar phenomena including
auroras and mesospheric clouds to meet requests from scientists
conducting ground research for the International Polar Year.

Crew Earth Observations have been ongoing since 1961and more than
250,000 images have been taken during the first six years of ISS
operations.


Experiment/Payload Description

Research Summary
The International Polar Year 2007-2009 will provide a snapshot of the
Polar Regions that will be used as a benchmark for detecting change in
the areas.
Observations, through digital still photography and video, from the
International Space Station through the Crew Earth Observation program
will be used with data gathered from satellites and ground
observations to understand the current status of the Polar Regions.
ISS, as a platform for observations will contribute data that has not
been available in the past and will set the precedent for future
international scientific collaborations for Earth observations.
Description
International Polar Year (IPY) 2007-2009 will be the fourth time in
the past 125 years that scientists world wide will combine efforts in
observation and exploration for the Earth?s Polar Regions. This IPY
will include observations made from the International Space Station
(ISS) through the Crew Earth Observation (CEO) program.

ISS provides a human observational platform to observe atmospheric
phenomena and repeated observations over the IPY. One area of research
in which ISS will be participating in is the observation of Polar
Mesospheric Clouds (PMC) and the Aurora phenomenon. PMC (also known as
noctilucent clouds) are thin clouds that are found in the mesosphere.
They are the highest known clouds with altitudes around 53 miles (85
km) and are visible only at night when illuminated by sunlight below
the horizon.

The crewmember will use digital still photography and videos to
capture targets that will be part of the CEO program. The targets will
be selected on their relevance to the IPY studies. Additional imaging
from satellites and ground observation stations will be compared to
the data collected by ISS.

Applications

Space Applications
Observations that are made from Earth?s orbit create the model for
planetary exploration observations on future long-duration missions.
Earth Applications
Data collected by CEO-IPY will be used by an international
collaboration of scientists to determine how the Polar Regions have
changed over the past 125 years and might help to explain atmospheric
phenomena such as Polar Mesospheric Clouds. The blueprint that the
data creates will be used to determine the changes in the Polar
Regions in the future. The data gathered will also be used as an
educational tool for teachers and students world wide.

Operations

Operational Requirements
Crewmembers will receive targets through the Crew Observations program
that were coordinated by the IPY researchers. Digital photography and
video will be taken by the ISS crews. Images will be downlinked to CEO
personnel who will catalog and make the images available to the IPY
researchers.
Operational Protocols
The IPY will begin in March 2007. The crewmembers will receive
uplinked coordinates for the targets of interest from the CEO program.
When the ISS passes over a specific target, the crewmembers will use
digital photography and video to capture the target. These images and
video will be downlinked to Johnson Space Center for cataloging and
distribution.

I have no problems whatsoever with an honest focus upon Earth science,
although when that science is costing us 100 to 1000 fold more because
it's ISS related, as this is when I'm having my second doubts.

If the ISS obtained science is so super-terrific and otherwise whole-
Earth extra special, then the very least we deserve is a look-see at
each of those entire raw image files, just exactly as CCD recorded.

We also need continuous video of whatever else is going on above the
horizon of Earth, and again w/o optical filters unless clearly
specified. If you can't, I'll help specify those cameras and of their
optics (of course this should have been accomplished as of more than a
decade ago).

Actually you cannot reduce down the scientific value of an image based
on your overly simplistic, arbitrarily determined dollar value, as you
are not considering the evaluation and comparisons of the image taken
in the present to, an image that will be taken in the future. For
instance see below the two images of the Patagonian ice field in
Chile, one taken by the expedition 16 crew in November 2007, and the
second image taken by the expedition 8 crew in November 2003. Now
based on you metric for an images value, the image taken in 2003 would
have been argued to be based on the cost of the program at the time,
but you argument fails as you are not including the future scientific
gains made from such comparisons as I have presented. And this same
logic applies to iss crews recording dynamic events that compliment
the observations that are made by earth observing satellites, so one
would ask you why are you afraid of combing the observations made by
iss crews, and those made from satellites, as the use of both can
produce a synergy of scientific information when combined. The value
of the any one image is not the cost of the program divided by the to
total number of images taken when the image is captured, but such a
cost "equation" should also take in account the future scientific
studies that can be accomplished from archiving such data for future
use. Also this same logic applies to all the science done on the iss,
which all iss science cannot be ignored as you have attempted to do
so, meaning you are using flawed logic when you make subjective
statements (which are basically repackaged complaints resulting in
your circular arguments) of what something should cost. Now with
respect to your repeated complaints about 18mb image access, you don't
use the images for any purpose other than making false color images
where the detail is blown out, and then you point out what should have
been captured in the image, but the problem is i have already
demonstrated that your statements produced from your image analysis
also suffer from flawed logic as well...

Here are the images of the Patagonian ice field in Chile, take by the
expedition 8, and 16 crews....

Mosaic of the Southern Patagonian Ice Field
http://eol.jsc.nasa.gov/EarthObserva..._Ice_Field.htm
Mosaic of the Southern Patagonian Ice Field
Outside of Antarctica, the largest contiguous ice field in the
Southern Hemisphere is the Southern Patagonian Ice Field in the Andes
Mountains of Chile and Argentina. It has an area of about 13,000
square kilometers, a length of approximately 360 kilometers (over
three degrees of latitude), and an average width of about 40
kilometers.

To the west of the ice field, nearly fifty significant outlet glaciers
reach sea level in rugged fiords on the Pacific coast. The largest of
these, Brüggen, was featured in a previous image on Earth Observatory.
East of the ice field, several of the larger glaciers on the eastern
flank form large piedmont lakes (such as Lago Argentina).

Whether taken on the ground or by remote sensing satellites,
scientific measurements of the ice field and its glaciers are
difficult to obtain due to the rugged terrain and harsh, stormy
climate of the region. The estimated loss of ice mass of this large
system is an important indicator of climate variability on both a
local and global scale. Additional information on this and other
Patagonian glaciers may be found at the following link: USGS -
Historic Fluctuations of Outlet Glaciers from the Patagonian Ice
Fields.

This image is a mosaic of two digital photographs (ISS004-E-6737 and
ISS004-E-6738) taken by astronauts onboard the International Space
Station in January 2002. Images were provided by the Earth Sciences

Bet you can't tell that one with a straight butt-crack to those losing
their jobs, homes and even having to give up whatever family status,
all because of your spendy as hell methods of science that hasn't
shown a scrap of human or environmental worth, especially of whatever
could just as easily been robotic if not terrestrial accomplished at
less than 1% the cost and within a tenth the time.

I suppose you even think our FEMA is worth keeping, and that your GW
Bush can do no wrong.
