Cassini Spacecraft to Monitor North Pole on Titan

Artist concept of NASA's Cassini spacecraft flying by the north polar region of Saturn's moon Titan on Dec. 27Though there are no plans to investigate whether Saturn's moon Titan has a Santa Claus, NASA's Cassini will zoom close to Titan's north pole this weekend.

The flyby, which brings Cassini to within about 960 kilometers (600 miles) of the Titan surface at 82 degrees north latitude, will take place the evening of Dec. 27 Pacific time, or shortly after midnight Universal Time on Dec. 28.

The encounter will enable scientists to gather more detail on how the lake-dotted north polar region of Titan changes with the seasons. Scientists will be using high-resolution radar to scan the large and numerous lakes in the north polar region for shape-shifting in size and depth. The ion and neutral mass spectrometer team will take baseline measurements of the atmosphere to compare with the moon's south polar region when Cassini flies by that area on Jan. 12. Cassini will also be collecting images for a mosaic of a bright region called Adiri, where the Huygens probe landed nearly five years ago.

Cassini will have released the Huygens probe exactly five years and three days before this latest flyby. Huygens began its journey down to Titan on the evening of Dec. 24, 2004 California time, or early Dec. 25 Universal Time, and reached the surface Jan. 14, 2005.

Cassini last flew by Titan on Dec. 11, 2009 California time, or Dec. 12 Universal Time. Although this latest flyby is dubbed "T64," planning changes early in the orbital tour have made this the 65th targeted flyby of Titan.

AcrimSat Celebrates 10 Years of Measuring the Sun's Energy

AcrimSatLaunched Dec. 20, 1999, the Active Cavity Radiometer Irradiance Monitor Satellite (AcrimSat) monitors the total amount of the sun's energy reaching Earth. It is this energy, called total solar irradiance, that creates the winds, heats the land and drives ocean currents. Some scientists theorize a significant fraction of Earth's warming may be solar in origin due to small increases in the sun's total energy output since the last century. By measuring incoming solar radiation, climatologists are using AcrimSat to improve their predictions of climate change and global warming over the next century.

Sunlight Glint Confirms Liquid in Titan Lake Zone

Reflection of sunlight off Titan lake
NASA's Cassini Spacecraft has captured the first flash of sunlight reflected off a lake on Saturn's moon Titan, confirming the presence of liquid on the part of the moon dotted with many large, lake-shaped basins.

Cassini scientists had been looking for the glint, also known as a specular reflection, since the spacecraft began orbiting Saturn in 2004. But Titan's northern hemisphere, which has more lakes than the southern hemisphere, has been veiled in winter darkness. The sun only began to directly illuminate the northern lakes recently as it approached the equinox of August 2009, the start of spring in the northern hemisphere. Titan's hazy atmosphere also blocked out reflections of sunlight in most wavelengths. This serendipitous image was captured on July 8, 2009, using Cassini's visual and infrared mapping spectrometer.

The new infrared image is available online at: http://www.nasa.gov/cassini, http://saturn.jpl.nasa.gov and http://wwwvims.lpl.arizona.edu.

This image will be presented Friday, Dec. 18, at the fall meeting of the American Geophysical Union in San Francisco.

"This one image communicates so much about Titan -- thick atmosphere, surface lakes and an otherworldliness," said Bob Pappalardo, Cassini project scientist, based at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "It's an unsettling combination of strangeness yet similarity to Earth. This picture is one of Cassini's iconic images."

Titan, Saturn's largest moon, has captivated scientists because of its many similarities to Earth. Scientists have theorized for 20 years that Titan's cold surface hosts seas or lakes of liquid hydrocarbons, making it the only other planetary body besides Earth believed to harbor liquid on its surface. While data from Cassini have not indicated any vast seas, they have revealed large lakes near Titan's north and south poles.

In 2008, Cassini scientists using infrared data confirmed the presence of liquid in Ontario Lacus, the largest lake in Titan's southern hemisphere. But they were still looking for the smoking gun to confirm liquid in the northern hemisphere, where lakes are also larger.

Katrin Stephan, of the German Aerospace Center (DLR) in Berlin, an associate member of the Cassini visual and infrared mapping spectrometer team, was processing the initial image and was the first to see the glint on July 10th.

"I was instantly excited because the glint reminded me of an image of our own planet taken from orbit around Earth, showing a reflection of sunlight on an ocean," Stephan said. "But we also had to do more work to make sure the glint we were seeing wasn't lightning or an erupting volcano."

Team members at the University of Arizona, Tucson, processed the image further, and scientists were able to compare the new image to radar and near-infrared-light images acquired from 2006 to 2008.

They were able to correlate the reflection to the southern shoreline of a lake called Kraken Mare. The sprawling Kraken Mare covers about 400,000 square kilometers (150,000 square miles), an area larger than the Caspian Sea, the largest lake on Earth. It is located around 71 degrees north latitude and 337 degrees west latitude.

The finding shows that the shoreline of Kraken Mare has been stable over the last three years and that Titan has an ongoing hydrological cycle that brings liquids to the surface, said Ralf Jaumann, a visual and infrared mapping spectrometer team member who leads the scientists at the DLR who work on Cassini. Of course, in this case, the liquid in the hydrological cycle is methane rather than water, as it is on Earth.

"These results remind us how unique Titan is in the solar system," Jaumann said. "But they also show us that liquid has a universal power to shape geological surfaces in the same way, no matter what the liquid is."

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. JPL manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. The visual and infrared mapping spectrometer team is based at the University of Arizona, Tucson.

Quiet Sun Means Cooling of Earth's Upper Atmosphere

Data from the TIMED (Thermosphere Ionosphere Mesosphere Energetics and Dynamics) mission are being used to understand the climate of the upper atmosphereNew measurements from a NASA satellite show a dramatic cooling in the upper atmosphere that correlates with the declining phase of the current solar cycle. For the first time, researchers can show a timely link between the Sun and the climate of Earth’s thermosphere, the region above 100 km, an essential step in making accurate predictions of climate change in the high atmosphere.

Scientists from NASA's Langley Research Center and Hampton University in Hampton, Va., and the National Center for Atmospheric Research in Boulder, Colo., presented these results at the fall meeting of the American Geophysical Union in San Francisco from Dec. 14 to 18.

Earth's thermosphere and mesosphere have been the least explored regions of the atmosphere. The NASA Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics (TIMED) mission was developed to explore the Earth’s atmosphere above 60 km altitude and was launched in December 2001. One of four instruments on the TIMED mission, the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument, was specifically designed to measure the energy budget of the mesosphere and lower thermosphere. The SABER dataset now covers eight years of data and has already provided some basic insight into the heat budget of the thermosphere on a variety of timescales.

Energy emitted by the upper atmosphere as infrared (IR) radiation in 2002 (top) and 2008 (bottom) -- In this SABER plot, Nitric Oxide (NO) is the IR emitterThe extent of current solar minimum conditions has created a unique situation for recent SABER datasets, explains Stan Solomon, acting director of the High Altitude Observatory, National Center for Atmospheric Research in Boulder, Colo. The end of solar cycle 23 has offered an opportunity to study the radiative cooling in the thermosphere under exceptionally quiescent conditions.

"The Sun is in a very unusual period," said Marty Mlynczak, SABER associate principal investigator and senior research scientist at NASA Langley. "The Earth’s thermosphere is responding remarkably — up to an order of magnitude decrease in infrared emission/radiative cooling by some molecules."

The TIMED measurements show a decrease in the amount of ultraviolet radiation emitted by the Sun. In addition, the amount of infrared radiation emitted from the upper atmosphere by nitric oxide molecules has decreased by nearly a factor of 10 since early 2002. These observations imply that the upper atmosphere has cooled substantially since then. The research team expects the atmosphere to heat up again as solar activity starts to pick up in the next year.

While this warming has no implications for climate change in the troposphere, a fundamental prediction of climate change theory is that the upper atmosphere will cool in response to increasing carbon dioxide. As the atmosphere cools the density will increase, which ultimately may impact satellite operations through increased drag over time.

The SABER dataset is the first global, long-term, and continuous record of the Nitric oxide (NO) and Carbon dioxide (CO2) emissions from the thermosphere.

"We suggest that the dataset of radiative cooling of the thermosphere by NO and CO2 constitutes a first climate data record for the thermosphere," says Mlynczak.

The TIMED data provide a climate record for validation of upper atmosphere climate models, which is an essential step in making accurate predictions of climate change in the high atmosphere. SABER provides the first long-term measurements of natural variability in key terms of the upper atmosphere climate.

"A fundamental prediction of climate change theory is that upper atmosphere will cool in response to greenhouse gases in the troposphere," says Mlynczak. "Scientists need to validate that theory. This climate record of the upper atmosphere is our first chance to have the other side of the equation."

James Russell III, SABER principal investigator and co-director of the Center for Atmospheric Sciences at Hampton University in Hampton, Va., agrees adding, "The atmosphere is a coupled system. If you pick up one end of the stick, you automatically pick up the other – they're intrinsically linked. To be as accurate as possible, scientists have to understand global change throughout the atmosphere."

As the TIMED mission continues, these data derived from SABER will become important in assessing long term atmospheric changes due to the increase of carbon dioxide in the atmosphere.

TIMED is the first mission in the Solar Terrestrial Probes Program within the Heliophysics Division in NASA's Science Mission Directorate in Washington.

The Dark Side of Carbon

As interest in Earth's changing climate heats up, a tiny dark particle is stepping into the limelight: black carbon. Commonly known as soot, black carbon enters the air when fossil fuels and biofuels, such as coal, wood, and diesel are burned. Black carbon is found worldwide, but its presence and impact are particularly strong in Asia.

Black carbon, a short-lived particle, is in perpetual motion across the globe. The Tibetan Plateau's high levels of black carbon likely impact the region's temperature, clouds and monsoon season.

NASA Outlines Recent Greenhouse Gas Research

distribution of mid-tropospheric carbon dioxideResearchers studying carbon dioxide, a leading greenhouse gas and a key driver of global climate change, now have a new tool at their disposal: daily global measurements of carbon dioxide in a key part of our atmosphere. The data are courtesy of the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft.

Moustafa Chahine, the instrument's science team leader at NASA's Jet Propulsion Laboratory, Pasadena, Calif., unveiled the new product at a briefing on recent breakthroughs in greenhouse gas, weather and climate research from AIRS at this week's American Geophysical Union meeting in San Francisco. The new data have been extensively validated against both aircraft and ground-based observations. They give users daily and monthly measurements of the concentration and distribution of carbon dioxide in the mid-troposphere--the region of the atmosphere located between 5 and 12 kilometers, or 3 to 7 miles, above Earth's surface, and track its global transport. Users can also access historical AIRS carbon dioxide data spanning the mission's entire seven-plus years in orbit. The product represents the first-ever release of global daily carbon dioxide data that are based solely on observations.

"AIRS provides the highest accuracy and yield of any global carbon dioxide data set available to the research community, now and for the immediate future," said Chahine. "It will help researchers understand how this elusive, long-lived greenhouse gas is distributed and transported, and can be used to develop better models to identify 'sinks,' regions of the Earth system that store carbon dioxide. It's important to study carbon dioxide in all levels of the troposphere."

Chahine said previous AIRS research data have led to some key findings about mid-tropospheric carbon dioxide. For example, the data have shown that, contrary to prior assumptions, carbon dioxide is not well mixed in the troposphere, but is rather "lumpy." Until now, models of carbon dioxide transport have assumed its distribution was uniform.

Carbon dioxide is transported in the mid-troposphere from its sources to its eventual sinks. More carbon dioxide is emitted in the heavily populated northern hemisphere than in its less populated southern counterpart. As a result, the southern hemisphere is a net recipient, or sink, for carbon dioxide from the north. AIRS data have previously shown the complexity of the southern hemisphere's carbon dioxide cycle, revealing a never-before-seen belt of carbon dioxide that circles the globe and is not reflected in transport models.

In another major finding, scientists using AIRS data have removed most of the uncertainty about the role of water vapor in atmospheric models. The data are the strongest observational evidence to date for how water vapor responds to a warming climate.

"AIRS temperature and water vapor observations have corroborated climate model predictions that the warming of our climate produced as carbon dioxide levels rise will be greatly exacerbated -- in fact, more than doubled -- by water vapor," said Andrew Dessler, a climate scientist at Texas A&M University, College Station, Texas.

3-D transport and distribution of water vapor as measured by AIRS from June through November 2005

Dessler explained that most of the warming caused by carbon dioxide does not come directly from carbon dioxide, but from effects known as feedbacks. Water vapor is a particularly important feedback. As the climate warms, the atmosphere becomes more humid. Since water is a greenhouse gas, it serves as a powerful positive feedback to the climate system, amplifying the initial warming. AIRS measurements of water vapor reveal that water greatly amplifies warming caused by increased levels of carbon dioxide. Comparisons of AIRS data with models and re-analyses are in excellent agreement.

"The implication of these studies is that, should greenhouse gas emissions continue on their current course of increase, we are virtually certain to see Earth's climate warm by several degrees Celsius in the next century, unless some strong negative feedback mechanism emerges elsewhere in Earth's climate system," Dessler said.

Originally designed to observe atmospheric temperature and water vapor, AIRS data are already responsible for the greatest improvement to five- to six-day weather forecasts than any other single instrument, said Chahine. JPL scientists have shown a major consequence of global warming will be an increase in the frequency and strength of severe storms. Earlier this year, a team of NASA researchers showed how AIRS can significantly improve tropical cyclone forecasting. The researchers studied deadly Typhoon Nargis in Burma in May 2008. They found the uncertainty in the cyclone's landfall position could have been reduced by a factor of six had more sophisticated AIRS temperature data been used in the forecasts.

AIRS observes and records the global daily distribution of temperature, water vapor, clouds and several atmospheric gases including ozone, methane and carbon monoxide. With the addition of the mid-tropospheric carbon dioxide data set this week, a seven-year digital record is now complete for use by the scientific community and the public.

NASA and Arab Youth Venture Foundation Launch Student Program

NASA and the Arab Youth Venture Foundation in Dubai, United Arab Emirates (UAE) have partnered to provide three to 12 UAE engineering students each year the opportunity to work with U.S. students, scientists, and engineers on NASA missions. The program's goal is to engage outstanding college students from the UAE in fields of science, technology, engineering and aerospace.

"The space program has a unique ability to inspire students to pursue excellence in disciplines that drive science and technology innovation," said Joyce Winterton, assistant administrator for education at NASA Headquarters in Washington. "With this Space Act Agreement, NASA will engage outstanding students in the UAE to continue their development in the critical skills of science, technology, engineering and mathematics."

Under this program, UAE students will join U.S. students in a research project administered by the Education Associates Program at NASA's Ames Research Center in Mountain View, Calif. UAE student involvement will provide U.S. student participants with valuable experience and knowledge about working together with representatives from other countries. The Education Associates Program anticipates its first group of Education Research Fellows in January 2010. Corporations and government entities in the UAE will sponsor the foundation's activities in full, including costs related to student lodging, housing, and transportation.

"There is much work to be done to promote and deliver inspired science, technology, education, aerospace and math education in the Arab world that is hands-on and conducted in real world settings," said Lisa-Renee LaBonte, chief executive officer of the Arab Youth Venture Foundation. "This groundbreaking program, administered by NASA, will provide select UAE citizens the opportunity to work with NASA scientists, researchers, and engineers on actual NASA missions."

Founded in Ras Al Khaimah, the Arab Youth Venture Foundation is dedicated to imagining and bringing to life initiatives that nurture the innovative spirits and entrepreneurial mindsets of youth aged six to 21 across the Arab world. The foundation's goal is to create activities that develop the next generation of scientific researchers, engineers, inventors, corporate leaders and entrepreneurs.

Since 1998, the Education Associates Program has placed more than 1,500 U.S. students from schools throughout the country in research positions working on NASA missions. Cooperation with the Arab Youth Venture Foundation will provide future U.S. participants in this NASA sponsored program at Ames with valuable cultural exposure and experience in working with their international counterparts.

This new partnership and NASA's many other education programs play a key role in preparing, inspiring, exciting, encouraging, and nurturing students in the critical disciplines of science, technology, engineering and mathematics.

Space Shuttle Crew Returns Home after 11-Day Mission

Space shuttle Atlantis and its crew of seven astronauts ended an 11-day journey of nearly 4.5 million miles with a 9:44 a.m. EST landing Friday at NASA's Kennedy Space Center in Florida.

The mission, designated STS-129, included three spacewalks and the installation of two platforms to the International Space Station's truss, or backbone. The platforms hold large spare parts to sustain station operations after the shuttles are retired. The shuttle crew delivered about 30,000 pounds of replacement parts for systems that provide power to the station, keep it from overheating, and maintain a proper orientation in space.

STS-129 Commander Charlie Hobaugh was joined on Atlantis' STS-129 mission by Pilot Barry Wilmore and Mission Specialists Leland Melvin, Randy Bresnik, Mike Foreman and Bobby Satcher. Atlantis returned with station resident Nicole Stott, who spent 91 days in space. This marks the final time the shuttle is expected to rotate station crew members.

A welcome ceremony for the astronauts will be held Monday, Nov. 30, in Houston. The public is invited to attend the 4 p.m. CST event at Ellington Field's NASA Hangar 990. Highlights from the ceremony will be broadcast on NASA Television's Video File. For NASA TV downlink information, schedules and links to streaming video, visit:

With Atlantis and its crew safely home, the stage is set for launch of shuttle Endeavour on its STS-130 mission, targeted to begin in February. Endeavour will deliver a pressurized module, known as Tranquility, which will provide room for many of the space station's life support systems. Attached to the node is a cupola, a robotic control station with six windows around its sides and another in the center that provides a 360-degree view around the station.

NASA Hosts Native Peoples Workshop to Study Climate Change

NASA will hold a second national strategies workshop to examine the impacts of climate change and extreme weather variability on native peoples and their homelands. The workshop, which will study the impacts from an indigenous cultural, spiritual and scientific perspective, will take place Nov. 18 - 21 at the Mystic Lake Casino Hotel in Prior Lake, Minn.

"This workshop will bring native indigenous knowledge together with science, education, and technologies to address the challenges of climate and environmental change," said Nancy Maynard of NASA's Goddard Space Flight Center in Greenbelt, Md.

The workshop will help ensure participation by tribal colleges and universities in the development of response and adaptation policies and recommendations regarding climate change. The goal is to ensure the survival of indigenous communities. The workshop is being held in collaboration with the nation's 36 tribally-controlled colleges and universities, the American Indian Higher Education Consortium, and other partners.

"Tribal college students represent many of the future tribal leaders who will inherit the consequences of climate change and be responsible for implementing the adaptation strategies," said Dan Wildcat of Haskell Indian Nations University in Lawrence, Kan. "It is critical that they have these kinds of opportunities to participate in key climate change discussions and build their science, technology, engineering and math skills."

Beginning of the End or Why the World Won't End - 2012?

Scenes from the motion picture 2012Remember the Y2K scare? It came and went without much of a whimper because of adequate planning and analysis of the situation. Impressive movie special effects aside, Dec. 21, 2012, won't be the end of the world as we know. It will, however, be another winter solstice.

Much like Y2K, 2012 has been analyzed and the science of the end of the Earth thoroughly studied. Contrary to some of the common beliefs out there, the science behind the end of the world quickly unravels when pinned down to the 2012 timeline. Below, NASA Scientists answer several questions that we're frequently asked regarding 2012.

Question (Q): Are there any threats to the Earth in 2012? Many Internet websites say the world will end in December 2012.
Answer (A): Nothing bad will happen to the Earth in 2012. Our planet has been getting along just fine for more than 4 billion years, and credible scientists worldwide know of no threat associated with 2012.

Q: What is the origin of the prediction that the world will end in 2012?
A: The story started with claims that Nibiru, a supposed planet discovered by the Sumerians, is headed toward Earth. This catastrophe was initially predicted for May 2003, but when nothing happened the doomsday date was moved forward to December 2012. Then these two fables were linked to the end of one of the cycles in the ancient Mayan calendar at the winter solstice in 2012 -- hence the predicted doomsday date of December 21, 2012.

Q: Does the Mayan calendar end in December 2012?
A: Just as the calendar you have on your kitchen wall does not cease to exist after December 31, the Mayan calendar does not cease to exist on December 21, 2012. This date is the end of the Mayan long-count period but then -- just as your calendar begins again on January 1 -- another long-count period begins for the Mayan calendar.

Q: Could a phenomena occur where planets align in a way that impacts Earth?
A: There are no planetary alignments in the next few decades, Earth will not cross the galactic plane in 2012, and even if these alignments were to occur, their effects on the Earth would be negligible. Each December the Earth and sun align with the approximate center of the Milky Way Galaxy but that is an annual event of no consequence.
Earth, as seen in the Blue Marble: Next Generation collection of images, showing the color of the planet's surface in high resolutionQ: Is there a planet or brown dwarf called Nibiru or Planet X or Eris that is approaching the Earth and threatening our planet with widespread destruction?
A: Nibiru and other stories about wayward planets are an Internet hoax. There is no factual basis for these claims. If Nibiru or Planet X were real and headed for an encounter with the Earth in 2012, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye. Obviously, it does not exist. Eris is real, but it is a dwarf planet similar to Pluto that will remain in the outer solar system; the closest it can come to Earth is about 4 billion miles.

Q: What is the polar shift theory? Is it true that the earth’s crust does a 180-degree rotation around the core in a matter of days if not hours?
A: A reversal in the rotation of Earth is impossible. There are slow movements of the continents (for example Antarctica was near the equator hundreds of millions of years ago), but that is irrelevant to claims of reversal of the rotational poles. However, many of the disaster websites pull a bait-and-shift to fool people. They claim a relationship between the rotation and the magnetic polarity of Earth, which does change irregularly, with a magnetic reversal taking place every 400,000 years on average. As far as we know, such a magnetic reversal doesn’t cause any harm to life on Earth. A magnetic reversal is very unlikely to happen in the next few millennia, anyway.

Q: Is the Earth in danger of being hit by a meteor in 2012?
A: The Earth has always been subject to impacts by comets and asteroids, although big hits are very rare. The last big impact was 65 million years ago, and that led to the extinction of the dinosaurs. Today NASA astronomers are carrying out a survey called the Spaceguard Survey to find any large near-Earth asteroids long before they hit. We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs. All this work is done openly with the discoveries posted every day on the NASA NEO Program Office website, so you can see for yourself that nothing is predicted to hit in 2012.

Q: How do NASA scientists feel about claims of pending doomsday?
A: For any claims of disaster or dramatic changes in 2012, where is the science? Where is the evidence? There is none, and for all the fictional assertions, whether they are made in books, movies, documentaries or over the Internet, we cannot change that simple fact. There is no credible evidence for any of the assertions made in support of unusual events taking place in December 2012.

NASA Seeks Student Payloads for High-Flying Research Balloon

NASA is accepting applications from students at U.S. colleges and universities who want to send their experiments to the edge of space on a high-flying scientific balloon.

The annual NASA project provides near space access for 12 undergraduate and graduate student experiments to be carried by a NASA high-altitude research balloon. The flights typically last 15 to 20 hours and reach an altitude of 23 miles. Experiments may include compact satellites or prototypes.

The experiments are flown aboard the High Altitude Student Platform, or HASP, a balloon-born instrument stack launched from the Columbia Scientific Balloon Facility's remote site in Fort Sumner, N.M. The goals of the project are to provide a space test platform to encourage student research and stimulate the development of student satellite payloads and other space-engineering products.

HASP seeks to enhance the technical skills and research abilities of students in critical science, technology, engineering and mathematics disciplines. The project is a joint effort between NASA and the Louisiana Space Grant Consortium.

NASA's HASP houses and provides power, mechanical support and communications for test articles and instruments. It can support approximately 200 pounds of student payloads. Since 2006, the HASP program has selected 44 payloads for flight, the work of more than 200 students from across the United States.

A question-and-answer teleconference for interested parties will be held Nov. 13 at 11 a.m. EST. The deadline for applications is Dec. 18. NASA is targeting fall 2010 for the next flight opportunity. NASA expects to make selections in January 2010. Teleconference dial in information, application materials and technical details are available in the Call for Proposals document at:

NASA Celebrates Earth Science Week

Every day at NASA scientists study changes on our home planet, and a significant portion of that study focuses on changes in our oceans. To showcase some of that research, NASA is releasing six short videos in commemoration of Earth Science Week 2009. The videos highlight the connection between climate change and our oceans.



The theme of Earth Science Week (October 11 through 17) this year is "Understanding Climate." The six NASA videos complete a series called "Tides of Change," which all focus on the ocean-climate connection. Each video features a specific component of the connection, such as marine life or the water cycle.

Another highlight of NASA's Earth Science Week contributions is a live educational webcast on October 14 at 1 p.m., EDT. Classrooms around the country will participate in this live event that focuses on Earth science discoveries and careers. Two oceanographers will discuss their careers, illustrate NASA’s unique, space-based view of the oceans and answer participant questions. Watch the webcast here.

Climate Change and the Global OceanAlso part of NASA's offerings, the agency's Global Climate Change Web site will feature these videos and a 3D interactive, "Eyes on Earth." The downloadable Eyes on Earth application allows users to observe the paths of satellites that study our planet, learn about related missions and more.

Earth Science Week, organized by the American Geological Institute, encourages people everywhere to explore our planet and learn about geoscience fields.

Though Earth Science Week 2009 only lasts through October 17, At NASA every week is Earth science week, as scientists continue to learn about our changing planet and what drives those changes. A world of Earth science exploration is all at your fingertips and on-line from NASA's Earth Web site any day of the week.
