Determine if the Martian arctic soil could support life.</span><br /><br />Life as we know it requires liquid water, but not necessarily its continuous presence. Phoenix will investigate a hypothesis that some ice in the soil of the landing site may become unfrozen and biologically available at times during the warmer parts of long-period climate cycles. Life might persist in some type of dormant microbial form for millions of years between thaws, if other conditions were right.<br /><br />The spacecraft is neither equipped nor intended to detect past or present life. However, in addition to studying the status and history of water at the site, Phoenix will look for other conditions favorable to life.<br /><br />One condition considered essential for life as we know it is the presence of molecules that include carbon and hydrogen. These are known as organic compounds, whether they come from biological sources or not. They can be produced without life, but they include the chemical building blocks of life, as well as substances that can serve as an energy source, or food, for life. Phoenix would be able to detect small amounts and identify them. The two Viking spacecraft that NASA landed on Mars in 1976 made the only previous tests for organic compounds in Martian soil, and found none. Conditions at the surface may be harsh enough to break organic molecules apart and oxidize any carbon into carbon dioxide. Phoenix will assess some factors in those oxidizing conditions and will check for organic chemicals below the surface, as well as in the top layer. Organic chemicals would persist better in icy material sheltered from sunshine than in surface soil exposed to harsh ultraviolet radiation from the sun. Organic compounds have been found in some meteorites that hit Earth. Scientists reason that meteorites raining onto Mars over the eons have delivered organic compounds to that planet, too. Whether these compounds can persist in a Martian environment is an important question in whether the environment would have been favorable or hostile to life.<br /><br />Phoenix will also be checking for other possible raw ingredients for life. It will examine how salty and how acidic or alkaline the environment is in samples from different layers. It will assess other types of chemicals, such as sulfates, that could be an energy source for microbes.<br /><br /><a href="http://www.nasa.gov/pdf/226508main_phoenix-landing1.pdf">NASA Phoenix Mars Lander Press Kit PDF File</a></blockquote><br /><br />In another article we read early on the concern of contamination of Mars being introduced by man titled:<br /><br /><blockquote><span style="font-weight: bold;">Biological contamination of Mars. I. Survival of terrestrial microorganisms in simulated Martian environments.</span><br /><br />Scher S, Packer E, Sagan C.<br /><br />Space Sciences Laboratory, University of California, Berkeley, California, USA.<br /><br />It has been postulated that the accidental introduction of terrestrial microorganisms to other planets during the course of space exploration might impede or bias the detection of organic matter and possible indigenous organisms, and thereby confuse subsequent studies of extraterrestrial life. To assess the likelihood of biological contamination of Mars, we have applied the principle of natural selection on a laboratory scale. Terrestrial microorganisms were collected from a variety of environments, including regions of high alkalinity, low mean daily temperature, and low annual rainfall. The air-dried soils were then subjected to a simulated Martian environment involving 12-hour freeze-thaw cycles from about -60 degrees C to about +20 degrees C; atmospheres of 95 per cent nitrogen, 5 percent carbon dioxide and low moisture content: < or =" 0.1" <a href="http://www.ncbi.nlm.nih.gov/pubmed/11883443">Life Sci Space Res. 1964</a> </blockquote><br /><br />Now, how are we to positively know that any type of experiments performed on the Mars surface haven't been compromised in some way? How do we know that we haven't contaminated the results of any experiment just by our very means of getting to the surface of Mars itself? How do we know we haven't brought microbes or carbon and hydrogen along for the ride with the Mars lander that won't affect the experiments? We are making assumptions about assumptions. We are assuming that everything has been sterilized to neutral. Remember what they say about assuming... Never ASSUME or you make an ... out of you and me.<br /><br />Science is the effort to understand, or to understand better, how the physical world works, with observable evidence as the basis of that understanding. It is done through observation of phenomena, and/or through experimentation that tries to simulate events under controlled conditions. Source Wikipedia<br /><br />While certain constants can be controlled in all experiments, there are however certain variables that can never be completely controlled. Additionally, having any false assumptions can affect the interpretation of the results.<br /><br />By-the-way, are you getting the results you want with business website online?

So, if that is in fact true, why is it said that the moon rotates?<br /><br />Apparently it has to do with your perspective. For the simple answer it seems as though it does not rotate on its own axis but as it rotates around the earth it does in fact have a rate of rotation (in reference to the earth) about the same rate of rotation for it to completely orbit the earth. Now, on the other side of the simple answer, the moon does in fact not really rotate at all in reference to the earth. It kind-of gyrates (wobbles) back and forth as it orbits the earth. Who is right? Does it rotate at the same speed as its orbit around the earth? Or, does the moon not rotate at all?<br /><br />For more in-depth explanations take a look at a number of different explanations<br /><ul> <li><a href="http://www.wonderquest.com/MoonSpin.htm">Does the moon rotate?

Which means that there is a membrane or membranes which are the main signal collection points. From there, the signals are focused onto another surface, where the signals are processed through a digital control unit. These units are all linked together and electronically steered together in an array to increase the signal processing capabilities and the antenna gain. See the example picture for an idea of the overall size of this space fed lens antenna versus the deep space one.<br /><br /><b>Etched Antenna Pictures Courtesy of <a href="http://e-fab.com">E-FAB, Inc.</a></b><br /><b><a href="http://e-fab.com/space-fed-lens-antennas.htm">Space Fed Lens Antenna</a></b><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://e-fab.com/images/Antenna-base-station-space-fed-lens-antenna.jpg"><img style="display:block; margin:10px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px;" src="http://e-fab.com/images/Antenna-base-station-space-fed-lens-antenna.jpg" border="0" alt="" /></a> Pictured above is a space fed lens, 3 meter panel which has 4 photo chemically etched sections all integrated into one unit.<br /><br />The way this particular antenna system is to be used is quite high tech.

Often, new operations concepts for a satellite or set of satellites emerge after launch. To the degree with which new space assets can be inexpensively and rapidly integrated into temporary or "ad hoc" constellations, will determine whether these new ideas will be implemented or not. On the Earth Observing 1 (EO-1) satellite, a New Millennium Program mission, a number of experiments were conducted and are being conducted to demonstrate various aspects of an architecture that, when taken as a whole, will enable progressive mission autonomy. In particular, the target architecture will use adaptive ground antenna arrays to form, as close as possible, the equivalent of wireless access points for low earth orbiting satellites. Coupled with various ground and flight software and the Internet, the architecture enables progressive mission autonomy. Thus, new collaborative sensing techniques can be implemented post-launch.<br /><br /><a href="http://eo1.gsfc.nasa.gov/new/SensorWebs/EO-1%20SPIE%20paper%20on%20Hotspots%202004%2011-18-04%5B1%5D.pdf">eo1.gsfc.nasa.gov/new/SensorWebs/EO-1 SPIE paper on Hotspots 2004 11-18-04</a></blockquote><br /><br /><b><a href="http://e-fab.com/ka-band-SpaceBorne-antennas.htm">JPL KA-Band Spaceborne Antennas</a></b><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://e-fab.com/images/Space-borne-ka-band-antenna-etched-strip.jpg"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px;" src="http://e-fab.com/images/Space-borne-ka-band-antenna-etched-strip.jpg" border="0" alt="" /></a><br />This is just one of 16 etched membrane strips that will be formed into a 3.2 meter antenna.

This article discusses the development of an inflatable/self-rigidizable structure for a 3-m 32-GHz (Ka-band) reflectarray antenna. This reflectarray antenna uses a beamscanning reflectarray antenna with circular-polarization technology. This technology uses a flat surface instead of a parabolic surface for the radio frequency component. A flat "natural" thin-membrane surface is much easier to accomplish and maintain than is a curved "non-natural" parabolic surface.<br /><br /><a href="http://tmo.jpl.nasa.gov/progress_report/42-149/149D.pdf">http://tmo.jpl.nasa.gov/progress_report/42-149/149D.pdf</a></blockquote><br /><br />Antenna manufacturing certainly has evolved over the years.

Radiotelemetry triangulation of transmitters was done early in the twentieth century during times of war to track down the enemy.<br />
<br />
Now a new type of triangulation method has been patented for the said purpose of targeting online advertising specifically to individuals in certain locales. The way it works is, the latency of the connection by an individual is measured from at least several points on the Internet. Triangulation can then be applied through the algorithm to determine the approximate location of the individual.<br />
<br />
The following link was forwarded to me by a reader.<br />
<a href="http://news.com.com/NSA+granted+Net+location-tracking+patent/2100-7348_3-5875953.html" target="ext">NSA granted Net location-tracking patent</a><br />
<br />
The technology has much broader applications appeal then just targeted online advertising.<br />
<blockquote>
Geo-location, sometimes called "geo-targeting" when used to deliver advertising, is an increasingly attractive area for Internet businesses. DoubleClick has <a href="http://news.com.com/DoubleClick+licenses+geo-targeting+tech/2110-1024_3-5177287.html?tag=nl" target="ext" title="DoubleClick licenses geo-targeting tech -- Monday, Mar 22, 2004">licensed geo-location technology</a> to deliver location-dependent advertising, and Visa has <a href="http://news.com.com/Quova+upgrade+pins+down+AOL+users/2100-1023_3-836138.html?tag=nl" target="ext" title="Quova upgrade pins down AOL users -- Wednesday, Feb 13, 2002">signed a deal</a> to use the concept to identify possible credit card fraud in online orders.</blockquote>
<br />
It appears as though companies have been using Geo-location targeting for quite some time on the Internet. As with any new technology developed, there are certainly altruistic, and security uses, but at the same time the possibilities exist for someone to abuse the power of these new technologies.<br />

Read this article on search algorithms and <a target="ext" href="http://marketing.pwebs.net/2008/03/13/online-marketing-means-knowing-your-customers-semantically/">computer semantics analysis</a>.<br /><br />However, we use algorithms everyday in our lives too — our minds.<br /><br />Our lives are based on decision making and step by step problem solving. An <a target="ext" href="http://www.answers.com/algorithm">algorithm</a> is a procedure for problem solving or an ordered step by step process for coming up with a solution.<br /><br />Sometimes the problems we face are simple in nature. For instance deciding what you are going to have for dinner or what show you want to watch on television. Your mind absorbs all the variables and spits out an answer based on likes and dislikes or what a friend or spouse would like also. Other times, problems are much more complex and difficult because of lack of experience, lack of education, or variables beyond your control. But even then the mind takes into account what is at hand, and delivers an answer based on the inputs.<br /><br />Mathematical algorithms are routines that can be run as computer software programs to come up with a answer based on a given set of variables.<br /><br />Now imagine taking this to another level. Suppose we develop a software training program to train individuals based on a given set of variables. Actually we do having training programs that as a person responds in a positive or negative way the software will then branch out to the next level or go into more detail for the application. Online gaming and other computer games throughout the later part of the 20'th century we're and still are very popular for getting to the end of a quest. Each level gets harder and harder, but skills are improved and tools are acquired along the way in your ever quest to become victorious.<br /><br />There is a great game called <a target="ext" href="http://www.javaonthebrain.com/java/mastermind">mastermind</a>.<br /><br />In this game of mastermind, one player builds a pattern of 4 or 5 pegs with 8 potential colors and/or blank spots. Then another player tries to figure out the pattern in the least amount of tries as possible. This second person builds a pattern and then the other player gives indicators on the number of right colors and the number in the right spots. This game is a great logical problem solving lesson because the person has to learn from the previous patterns.<br /><br />Personal learning algorithms function in the same way as mastermind. This can be applied to any part of our lives. There could also be some amazing outcomes using algorithms for teaching without a student actually aware of this going on. A program could be built to not only train a person, but by building into the program a means of self learning, one could improve the underlying foundation of the program itself, while also training the individual using it.<br /><br />Another example of a learning algorithm is the yes no game, where an individual tells a story without giving any details and then asks the audience how did it happen. The story teller can only give yes or no answers with the person having to logically figure out what happened. Sometimes it may require giving occasional tips to help prompt the thinking process. This game was adapted to the small hand held gaming device called twenty questions. Radica 20Q Artificial Intelligence Game<br /><br /><span style="font-weight: bold;">So, how do learning algorithms really affect us in our everyday lives?</span><br /><br />First off, as the technology world becomes more and more complex, it requires individuals and businesses to develop their skills at problem solving. Sometimes the only way to advance dramatically, is to probe and move forward in a direction and make a decision. The fastest way to get an answer is not by standing still, but by trying a move and see what the results are. Doing things exclusively the old way may be the safe way, but will not be as rewarding as a new move, with the potential for even better business results.
