Talk Show for Kids
Searching for ways to get children to think about careers in science?  NASA's Space Place Website offers a cartoon "talk show" for kids with NASA scientists and engineers chatting about their work, how they chose their careers, and what they like to do for fun. Visitors to the site can simulate working on space and earth science missions. Children can also explore science related games, science projects, animations, science facts and other related topics.

AstroCapella
AstroCapella is a great resource for librarians or teachers! AstroCappella combines hands-on activities with rocking, high-energy songs written and performed by The Chromatics. The lessons can stand alone and explore how radio telescopes work, what the surfaces of our nearest-neighbor planets are like, and more. Or you can just use the music CD as a starting point for other types of activities — the songs help to explain concepts and provide mnemonics to help the children learn and remember. The songs cover the full spectrum, from radio astronomy, through optical observations with the orbiting Hubble Space Telescope, to the powerful pulsars, black holes and quasars of high-energy X-ray astronomy. They provide a springboard to explore the Sun and Moon, the nine planets, and the nearest stars. Cost is $15 with bulk order discounts possible.

ISS EarthKAM 
ISS EarthKAM (Earth Knowledge Acquired by Middle School Students) is a NASA sponsored program that provides high quality photographs of our planet taken from the Space Shuttle and International Space Station. Since 1996, ISS EarthKAM students have taken thousands of photographs of Earth by using the World Wide Web to direct a digital camera on select space flights and currently on the International Space Station. The main objective is to enable students, teachers, informal educators and the public to learn about Earth from the unique perspective of space. At the core of the program is a spectacular collection of digital images of Earth. The image collection and accompanying learning guides and activities are extraordinary resources to support classes in Earth science, space science, geography, social studies, mathematics, communications and even art.

Mission News and Science

Stardust
Modified from: http://stardustathome.ssl.berkeley.edu/background.html
In January 2006, NASA's Stardust mission will return to Earth after nearly 7 years in interplanetary space. During its journey Stardust encountered Comet Wild-2, collecting dust particles from it in a special material called aerogel.  The scientific importance of these first solid samples from our Galaxy can't be overstated. Interstellar dust and gas were the building blocks of our solar system, the Earth, and all living things, including people. We are truly made of stardust.

At two other times in the mission, the aerogel collectors were also opened to collect interstellar dust. By studying this dust, scientists hope to learn about the origins of the Solar System. They wish to know what the ingredients were that went into making it. When the mission returns, the aerogel collectors exposed to the interstellar dust will be scanned by an automated microscope. There will be approximately 1.6 million fields of view, but perhaps only a few dozen total grains of interstellar dust in the entire collector; it will be like finding the proverbial needle in a haystack.

Venus Express
Modified from: http://skyandtelescope.com/news/article_1624_1.asp
The European Space Agency successfully launched Venus Express from Kazakhstan last month. The spacecraft carries cameras, spectrometers and other instruments to study the atmosphere and near-space environment of Venus from an elliptical polar orbit around the planet. Venus Express will pull into orbit around our closest planetary neighbor and begin five months of scheduled observations. On the short list of mission objectives: a detailed mapping of Venus' surface, a survey of the planet's complex atmosphere, and a look into the possibility of active Venusian volcanoes. Venus Express will arrive at its destination in April 2006 — our first return to Venus since October of 1994 when the Magellan mission ended with a dramatic plunge to the planet's surface.

NASA Rover Helps Reveal Possible Secrets of Martian Life
Modified from: http://www.nasa.gov/vision/universe/solarsystem/mer-20051129.html
Was Mars early environment conducive to life? A recent study of data obtained by NASA's Opportunity rover now shows that life may have had a tough time getting started in the ancient harsh Martian environment. Scientists have been able to deduce conditions in the Meridiani Planum region of Mars were sometimes wet, strongly acidic and oxidizing. Those conditions probably posed stiff challenges to the origin of Martian life.

Scientists analyzed data about stacked sedimentary rock layers 23 feet thick, exposed inside "Endurance Crater." They identified three divisions within the stack. The lowest, oldest portion had the signature of dry sand dunes; the middle portion, windblown sheets of sand with all the particles produced in part by previous evaporation of liquid water. The upper portion corresponded to layers Opportunity found earlier inside a smaller crater near its landing site.

Materials in all three divisions were wet both before and after the layers were deposited by either wind or water. Researchers described chemical evidence that the sand grains deposited in the layers had been altered by water before the layers formed. The stack of layers in Endurance Crater resulted from a changeable environment perhaps 3.5 to 4 billion years ago. The area may have looked like salt flats occasionally holding water, surrounded by dunes. The Rio Tinto region of White Sands, New Mexico bears a similar physical resemblance. Many types of microbes live in the Rio Tinto environment, one of the reasons for concluding that ancient Meridiani could have been habitable. However, the organisms at Rio Tinto are descended from populations that live in less acidic and stressful habitats. If Meridiani had any life, it might have had to originate in a different habitat.


NASA Discovers Life's Building Blocks Are Common in Space
Modified from: http://www.astrochem.org/PANHS.html
A team of NASA exobiology researchers revealed recently that organic chemicals that play a crucial role in the chemistry of life are common in space. NASA's Spitzer Space Telescope has shown complex organic molecules called polycyclic aromatic hydrocarbons (PAHs) are found throughout our galaxy.  PAHs, large, flat, chicken-wire shaped molecules made up of hydrogen and carbon, are extremely stable and can withstand the hostile radiation environment of interstellar space. The NASA team showed that PAHs are responsible for the mysterious infrared radiation that astronomers first called the Unidentified Infrared Emission. NASA's Spitzer Space Telescope has now detected the PAH tell-tale signature throughout our galaxy the Milky Way and in galaxies very far away, galaxies nearly as old as the Universe itself.  Now the NASA team has found that these PAHs contain nitrogen, a key biochemical element.

Life requires organic molecules that contain nitrogen. Chlorophyll, the substance that enables photosynthesis in plants, is a good example of this class of compounds, called polycyclic aromatic nitrogen heterocycles, or PANHs. Ironically, PANHs are formed in abundance around dying stars. So even in death, the seeds of life are sewn. The NASA team studied the infrared "fingerprint" of PANHs in laboratory experiments and with computer simulations to learn more about infrared radiation that astronomers have detected coming from space. They used data from the European Space Agency's Infrared Space Observatory satellite.

Did You Know?

Why the Winter Solstice is called the Winter Solstice
Modified from: http://www.jackstargazer.com/scripts0SG0550.html
Wednesday Dec. 21st the winter solstice officially begins for the northern hemisphere. But if you're like most people, the concept of the winter solstice can be a bit confusing. To fully understand the concept imagine the first day of spring. The first day of spring is also called 'the vernal equinox', vernal meaning 'green', and equinox meaning 'equal night', which simply means that on the equinox the hours of daylight are equal to the hours of night. On the first day of spring, the vernal equinox, the Sun rises exactly due east and sets exactly due west. And each successive day thereafter it rises and sets just a little bit farther to the north until the summer solstice, the first day of summer, when the Sun reaches its northernmost point along the horizon and actually seems to 'stand still' and rise and set in the same place for a few days. In fact the word 'solstice' means 'Sun stands still'.

The first day of summer is the longest day of the year or the day of longest daylight. After the solstice the Sun will appear to reverse its direction and will rise and set just a little bit farther south each successive day. And each successive day the time of daylight will grow just a little bit shorter and on the autumnal equinox, the first day of autumn, the Sun will once again rise due east and set due west and the hours of daylight will again be equal to the hours of night. Then the Sun will continue its journey southward rising and setting a little bit farther south each day and daylight will continue to get shorter and night time longer each day until the winter solstice, the first day of winter, when the Sun will reach its farthest point south and once again will appear to 'solstice' that is stand still and rise and set in the same place for a few days. And at the time of the solstice, the northern hemisphere will experience the shortest day of the year, meaning the day of least sunlight and most night. Then a few days after the solstice the Sun will appear to retrace its steps and will rise and set just a little bit farther north on the horizon each successive day until once again we'll be back where we started on the vernal equinox, the first day of spring and the Sun will rise and set due east and west.
