Prometheus: Over Easy

Prometheus as seen by Cassini
Prometheus displayed its pockmarked, irregular surface for NASA's Cassini spacecraft on Jan. 27, 2010.
Looking for all intents and purposes like a celestial egg after a session in Saturn's skillet, Prometheus displayed its pockmarked, irregular surface for NASA's Cassini spacecraft on Jan. 27, 2010.

Prometheus is one of Saturn's innermost moons. It orbits the gas-giant at a distance of 139,353 kilometers (85,590 miles) and is 86 kilometers (53 miles) across at its widest point. The porous, icy-bodied world was originally discovered by images taken by Voyager 1 back in 1980. You could say this latest "egg-cellent" view has the Cassini science team licking their chops at the thought of future Prometheus images.

This raw, unprocessed image of Prometheus [pro-MEE-thee-us] , taken in visible light, was obtained by Cassini's narrow-angle camera at a distance of approximately 36,000 kilometers (23,000 miles).

The Cassini Equinox Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. For more information about the Cassini Equinox Mission visit: http://www.nasa.gov/cassini and http://saturn.jpl.nasa.gov.

Envisioning Future Flight

Edric San Miguel's design concept, The Silent Airliner, was the first-place winner in the U.SToday's students will be designing tomorrow's aircraft, and NASA's Fundamental Aeronautics Student Competition gives them a head start.
Each year, the competition challenges students to research a particular real-world issue in aeronautics and to develop their own solutions to the problem.

Past participants in NASA's Fundamental Aeronautics Student Competition said the experience was a rewarding one that helped them learn more about aeronautics and encouraged them to improve their approaches to research and creative problem-solving.

In the 2008-2009 competition, students were challenged to develop ideas for making commercial supersonic air transportation available by 2020. Contest participants did so by examining obstacles to supersonic transportation and proposing solutions. In an additional challenge, some students submitted designs for a small supersonic airliner.

The top U.S. individual winner won a $1,000 cash prize, and members of the top U.S. team split $1,500. International students were not eligible for cash prizes but received an engraved trophy. All participants received a NASA certificate and free student versions of two engineering software programs.

Edric San Miguel was the first-place winner in the U.S. individual category for his design concept, "The Silent Airliner." When he entered, San Miguel was a junior at the Norfolk Technical Center in Norfolk, Va.

San Miguel is a student in Norfolk Public Schools' NORSTAR Gifted Program, which promotes scientific research, robotics, inventions and innovations. He first entered the program after being told about it by his teacher, Joy Young, during his sophomore year.

Edric San Miguel is a student in Norfolk Public Schools' NORSTAR Gifted Program"That year, I entered the competition as an individual and placed second in the U.S. individual awards category," he said. "I tied with a senior from Arizona. Last year, I decided that I would take on the next challenge of the contest as a high school junior. That is when I placed first place in the entire high school division."

The aeronautics contest is just one way San Miguel has been involved with NASA. During the summer, he participated in the NASA Langley Aerospace Research Summer Scholars project. "Through this program, I worked as an intern at NASA Langley's Systems Analysis and Concepts Directorate and Aeronautics Systems Analysis Branch," he said. He continued working as an intern through the fall session as a part-time intern. He plans to participate in the aeronautics contest again.

"The biggest thing I got out of this contest is the internship," he said. "Through this internship, I was able to work with NASA engineers and experience what aeronautical engineers do. I was able to make new friends with my fellow interns, establish contacts with engineers, and enter the pipeline into working for NASA."

San Miguel hopes to attend Virginia Tech and major in aerospace engineering and minor in business management.

Second place in the individual category went to Andrew Andraka, who was a sophomore at Bishop Hendricken High School in Warwick, R.I., at the time he designed his entry, "Next-Generation Supersonic Airliner."

"I learned about this contest two years ago when my dad pointed it out, noting it was a topic where I could write all I wanted about airplanes," he said. "The first essay I wrote was 'The Next Generation DC-3,' where I designed a hybrid aircraft encompassing a canard wing setup, coupled with a Custer Channel wing. I received an honorable mention for my essay, so I decided I would try again with the 'Next Generation Supersonic Airliner.'"

Participating in the contest, Andraka said, was both a good learning experience and an enjoyable opportunity. "I learned a lot more about airline design and the thought process entailed to devise original concepts," he said. "It also gave me a good excuse to expand my library of aviation resources."

Andrew Andraka hopes to establish his own aircraft research and production company somedayAndraka said that after majoring in aerospace engineering, he hopes to start an aircraft research and manufacturing company, specializing in light-sport aircraft and general aviation aircraft. He is working on flight training and hopes to be a private pilot with multiple endorsements before graduating college.

Jason Jong and Ziang Xie, of Arcadia High School in Arcadia, Calif., won first place in the U.S. team category of the contest. Jong, a junior at the time of the entry, and Xie, then a senior, named their design concept "The Lazarus T1."

"I had never participated in the NASA aeronautics competition nor any other NASA related or funded opportunities before entering the aeronautics competition," Jong said. "I don't quite remember, but I believe I was simply clicking around on NASA's Web site and came across the 'student contests' section for high schoolers. From the list, I saw the aeronautics contest, described as an aircraft design contest. At the time, I was an incoming sophomore. From about seventh-grade, I have had a lot of enthusiasm with airplanes, reading books, and searching the Web, so naturally, the contest was something I really really gravitated towards. I made a goal to enter, but unfortunately I waited until my junior year before I organized the completion of the project.

"The most rewarding aspect of entering this contest was the openness in creativity the contest allowed to designers," Jong said. "Though I have seen many plane designs through photos online, it was not until I entered this competition that I began piecing together feasible airplane designs of my own and developing my own imagination, like a precursor to actual aerospace engineering. It really brought a sense of creativity that I find rewarding, considering what we were able to accomplish."

Jason Jong and Ziang Xie split the responsibilities in creating their entry for the contestJong is currently applying to colleges. "My intended major is physics, which I have always liked," he said. "However, engineering seems a likely major for me as well, as my dad is a civil engineer. I'm keeping my options open for now. And, if I don't get into college, the Air Force sounds like a mighty fun place to go too!"

Xie heard about the contest through Jong. "I had never participated in this or any other NASA-affiliated contest before, with the exception of a regional Science Bowl competition at JPL (NASA's Jet Propulsion Laboratory), and at first I was hesitant about entering with my minimal knowledge," he said. "I gradually became more interested in the contest, however, as my teammate described how our submission would address issues with supersonic flight. We decided Jason would handle most of the basic design components, and I would work on creating a CAD model of our plane as well as help research technological advances, which might make supersonic flight more plausible in the future.

"The Fundamental Aeronautics competition piqued my interest in aeronautics and also helped me learn how to collaborate with a teammate in writing a design proposal," Xie said. "Most importantly, I learned how to quickly research and become more knowledgeable about a specific field."

Xie is currently attending UC Berkeley, majoring in electrical engineering and computer science.

NASA Provides Inside Look at International Space Station with Streaming Video

NASA soon will provide Internet viewers an inside look at astronauts working in space by streaming video live from the International Space Station's laboratories. The internal views are set to begin Feb. 1 and will be available during all crew duty hours.

Since March 2009, NASA has provided streaming video online of Earth and the station's exterior as the laboratory complex orbits 220 miles above Earth at 17,500 miles per hour. The new in-cabin streaming video includes audio of communications between Mission Control and the astronauts, when available.

Television from the station is available only when the complex is in contact with the ground through its high-speed communications antenna and NASA's Tracking and Data Relay Satellite System. During "loss of signal" periods, Internet viewers may see a test pattern. When the space shuttle is docked to the station, the stream will include video and audio of those activities.

The station is a unique partnership between the space agencies of the United States, Canada, Europe, Japan and Russia. Construction began in 1998 and will be completed in 2010. Twenty-two crews have lived aboard the orbiting laboratory since 2000, including the current crew of five. Station residents have conducted important scientific experiments and gathered data to help assist future missions.

To view the streaming station video on Feb. 1, visit:

Famous people with cancer


Instances of cancer are on the rise, and have become more and more common and more highly publicized in recent times. Many people know or are aware of someone that either has or has had cancer, whether this is a friend, relative or someone at work. There are many cases, of course, of famous people that have – or have had – cancer. Kate Jackson, perhaps the most famous of the original Charlie’s Angels from the original 1970s TV series, battled against cancer in 1987 and 1989, as did the singer and star of Grease, Olivia Newton John, who having been diagnosed in 1992 underwent surgery for a mastectomy and breast reconstruction.

Also of original Charlie’s Angels fame Jacelyn Smith found a lump back in 2002 and underwent treatment, including radiation and a lumpectomy. Many people, especially as the myth is precipitated by the mass media, believe that breast cancer only affects women. However Richard Roundtree, star of the original 1970s Blaxploitation classic Shaft, was also diagnosed with breast cancer in 1993 and underwent grueling rounds of chemotherapy and also a mastectomy.

Interestingly, not everyone opts for conventional forms of treatment when they are diagnosed with cancer, however scary a diagnosis it may be. Radical approaches to cancer treatment can cause considerable controversy when your are a celebrity – and such was the case for soap actress and author Suzanne Somers who opted to forgo standard cancer treatments in favor of holistic medicine and alternative therapies. Many believed at the time that this set a bad and even dangerous example to other sufferers and potential sufferers,

The singer-songwriter and former music teacher Sheryl Crow was also diagnosed with breast cancer in February 2006, and the condition was found to be at an early stage. She started off having only slightly invasive surgical treatment, followed-up with radiotherapy. In the following year, she made a documentary called Crazy Sexy Cancer. Her one-time husband, seven-time tour de France winner Lance Armstrong also suffered from testicular cancer and underwent chronic radiation therapy and surgery – and this was even before he won the tour!

Australian pop star and one-time Neighbors star, Kylie Minogue, also found herself facing a diagnosis of early-stage breast cancer in 2005. This caused her to put a halt to her grueling tour itinerary so that she could under chemotherapy and radiotherapy treatments. Showing just how much of an influence celebrities have on the general public consciousness with such things, her diagnosis caused a steep rise in women aged between 25-44 deciding to have breast imaging and biopsies to check for the disease.

Sex and the City’s Cynthia Nixon, who portrays the lawyer Miranda Hobbs in the highly successful show, underwent her battle with cancer in 2002 and initially stayed silent about her condition, choosing to campaign out of the media spotlight. She later became a cancer activist, and in 2008 became the ambassador and spokesperson for Susan G. Komen for the Cure.

Engineering Parallels Between Ephemerisle & Seasteading

There are a wide variety of opinions in the seasteading community about whether Ephemerisle is a plausible path to full seasteading. Here's my pre-event pitch of why Ephemerisle is useful. Post-event, I have an additional thought.

Our Ephemerisle structure and setup basically worked as plan, with a few exceptions. One is that it took longer than we expected, and was not completed by the noon Friday starting time (although everything did come together for Saturday evening).
