Fall 2012: Jeffrey InouyeTITAN

Titan is the second largest moon in our solar system. Titan is Unique because it has a dense atmosphere which makes it hard to observe its surface and the moon has vast lakes of liquid methane. The Cassini orbiter is currently gathering information about the massive moon and will continue to beyond 2015. Surprisingly, the data collected is raising more questions than it is answering.


Introduction to Titan

Site Name: Sea and Sky Presents- The Skyhttp://www.seasky.org/solar-system/saturn-titan.htmlAudience: Suitable for all ages.Summary: This website contains general information about the moon Titan. The site uses clear and simple language which makes it useful for 8th grade and above. The general information includes the size, the origins of the name, and information about its discovery. This website contains a wide variety of pictures.My Opinion: This site is very useful as a starting point for anyone researching Titan.

Advanced General Information

Site Name: Windows to The Universe (2009)http://www.windows2universe.org/saturn/moons/titan.html&edu=highAudience: High school and above.Summary: This website contains more advanced and detailed information about Titan. This website is most useful for gathering expanded information because it is full of CURRENT links that are relevant to various topics/ theories surrounding Titan.My Opinion: This website caught my attention because the text included so many links to other topics that it was almost distracting. The links seem to be periodically updated which provides up-to-date info regarding recent discussions, and discoveries. If you don’t understand any of the terminology or vocabulary, the links provided will lead you to pages which will help to clarify.

Animation of Titan’s Interior

Site Name: NASA –CassiniMission. (2008).http://www.nasa.gov/mission_pages/cassini/multimedia/pia10243.htmlAudience: High school and above.Summary: This website focuses on the theories proposed to explain an unexpected shift in Titan’s surface. The Cassini-Huygens Mission collected data on the moon between 2005-2007. The Cassini spacecraft plotted the positions of various landmarks on Titan’s surface but over time analysis showed that the landmarks had shifted significantly with no known explanation. The theory is that there may be a layer of liquid water under the entire surface which is causing land masses to rotate at an unexpected rate.My Opinion: I would use this site for more detailed projects. The article is scholarly in nature which makes it credible for any formal research paper. The Article is short and the topic is narrow, but the possible presence of liquid water on such a large moon could change common-held beliefs of how rare liquid water is in the universe.

Organic Building Blocks On Titan?

Site Name: The Daily Galaxy (2009).http://www.dailygalaxy.com/my_weblog/2009/02/saturns-titan-p.htmlAudience: High school and above.Summary: This website contains information about the possible discovery of organic building blocks in Titan’s upper-atmosphere. The site also contains a quality x-ray picture of the vast lakes of liquid methane and additional links.My Opinion: The article on this website is detailed but uses scientific terminology and a lot of statistics which may be intimidating to some. However, the discovery of organic materials on any celestial body is monumental and worth noting in any research assignment.

The Cassini-Huygens Mission
Site Name: CaliforniaScienceCenter (2011).
Audience: Suitable for all ages.
Summary: This website has everything you would want to know about the Cassini-Huygens mission. The site includes the complete history of the mission and all technical specifications of the spacecraft. There are also pictures of the spacecraft and a collection of links to related topics. The site also has a link to “Kids Space” which is a Cassini site made just for kids.
My Opinion: This site is very informational but is solely dedicated to the Cassini missions. The best thing about the site is that it is kept up-to-date. The site claims they are the “internet authority on the Cassini mission”.

Titan: Saturn's Largest Moon

-This page contains tons of useful information, charts, sound clips, and extra related links.
Author: The Planetary Society
Date Reviewed: April 9, 2009
Intended Audience: Amateur/ General
Useful for: Students/ Teachers/ Anybody Interested
Summary: This webpage is neat because it has an audio clip of the sounds recorded from Titan landers which is something I haven't seen yet reviewing pages. I'm not sure how useful this would be, but along with each clip is a description of the sounds that you are hearing. Like most informational pages, this site includes basic data regarding Titan such as size, orbital radius/period, and discovery. Also, it shows a chart comparing surface temperature/pressure, major/minor gases and cloud layers of Titan with those of Earth. It touches on the components in Titan's atmosphere and the possibility that there is a methane cycle similar to Earth's water cycle. Another large chart is shown as well with information about every flyby done around Titan. Within the "Flyby" header is a list of the new naming scheme for surface features discovered by the current spacecraft Cassini.
Opinion: I think that this site is full of research information that is different from most webpages. It gives a bunch of charts and extra links with related topics. The only things missing that could be useful are images and the mythological story of Titan.

Saturn's Moon Titan

Author: Calvin J Hamilton
Date Reviewed: 4/22/2009
Intended Audience: General Public/Amateur
Accuracy: The table given on the initial page provides very accurate numbers and measurements about Titan. From its mass to its atmospheric pressure, the numbers are listed beside each category and provided with a unit of measurement. Though the last updated date is unknown, the information seems to be the same from other comparable websites.
Review: Easy to navigate, lots of information and quite a few pictures make this a very good place to start when looking for information on Titan. Information is presented well, and no special knowledge is required to understand it. Images are divided into two sections, images from the Cassini probe and images from the Huygens probe. All images have captions descriptive of what is seen in the image, and how the image was obtained. Also contains equally good information on a number of Saturn's other moons. Overall this is a good website for basic Titan information and images.

Audience: College Students
Accuracy: The author talks about a possible space mission to the moon Titan and how it may be possible. It is accurate in terms of the discussions and possibilities that could happen if we were to embark on this mission; whether or not it is going to happen, is still yet to be determined.
Readability and Clarity: The information is quite dense in terms of understanding the language and comprehending the material being given. The reader must take their time in understanding the language and reading the information being given about the subject. The point of the article could not simply be achieved by skimming across the passages. In terms of the layout and overall view of the content, it is clean and organized well between thoughts and subjects.
Ease of Navigation: The page could only be found if you were looking for this specific subject of exploring the moon Titan. If you were to search Titan in a general field, you probably would not come across this page without having to jump from a few websites. Upon arriving on the page, it is fairly simply to navigate your way through the webpage.
Review: I find this page very interesting to learn about the possibilities of future space missions into our Solar System. Titan is one of the few objects near us that has a notable atmosphere, and exploring the future missions to come can benefit us. The author gives a different perspective on how this would actually come about, and it might be something we can see in our lifetime.
