NASA NAMES CHAIRMAN FOR ORBITING CARBON OBSERVATORY INVESTIGATION
WASHINGTON -- NASA's Rick Obenschain, deputy director at NASA's Goddard Space Flight Center in Greenbelt, Md., will lead the investigation board for the unsuccessful launch of the Orbiting Carbon Observatory on Feb. 24.

OCO's Randy Pollock Shares his Thoughts After Launch
A few hours ago I had the privilege to watch the Orbiting Carbon Observatory launch from Vandenberg Air Force Base. The creativity, effort and dedication of many, many people were sitting on the launch pad.

Five Things About the Orbiting Carbon Observatory
Here are some quick facts about the Earth-orbiting satellite, scheduled to launch on Feb. 24, 2009.
-- It will study carbon dioxide sources (where it comes from) and sinks (where it is pulled out of the atmosphere and stored). Carbon dioxide is a major contributor to global warming. The new data will help scientists more accurately forecast global climate change.

NASA Mission Meets the Carbon Dioxide Measurement Challenge
The challenge: very precisely measure carbon dioxide in Earth's atmosphere all over the world, especially near Earth's surface.
For Orbiting Carbon Observatory Principal Investigator David Crisp of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and his team, the logical solution was an Earth-orbiting spacecraft. But shopping for a science instrument that could accomplish these objectives was no easy task.

The Mystery of the Missing Carbon: A JPL Live Chat
NASA satellite sleuth set to launch this month will soon be hot on the trail of the elusive greenhouse gas carbon dioxide, the leading human-produced cause of global warming. The Orbiting Carbon Observatory's mission is to find the vast warehouses of carbon dioxide that are "missing" - hidden in "sinks" around the globe. Finding them will help scientists better predict how our climate will change in the future

First NASA CO2 Satellite Set for Launch
In their studies of global climate change, NASA's science teams are using Earth-observing satellites to map everything from floods and wildfires to El Ninos and phytoplankton. They track sea ice breakups and make daily scans of temperatures from the bottom of the troposphere to the top of the stratosphere. Wonder where smog-producing ozone is concentrated? Data from NASA's spacecraft reveal the ugly picture.

NASA Carbon Mission to Improve Future Climate Change Predictions
Recent years have seen an increase in record-setting events related to climate change. For example, 2005 was the warmest year globally in more than a century, and in 2007, Arctic sea ice retreated more than in any other time in recorded history. A new NASA mission set to launch later this month will help scientists better understand the most important human-produced greenhouse gas contributing to climate change: carbon dioxide. Called the Orbiting Carbon Observatory, the satellite may help us better predict how our climate may change in the future.

NASA Mission to Help Unravel Key Carbon, Climate Mysteries
NASA's first spacecraft dedicated to studying atmospheric carbon dioxide is in final preparations for a Feb. 23 launch from Vandenberg Air Force Base in California. Carbon dioxide is the leading human-produced greenhouse gas driving changes in Earth's climate.

The Orbiting Carbon Observatory and the Mystery of the Missing Sinks
Picture a tree in the forest. The tree "inhales" carbon dioxide from the atmosphere, transforming that greenhouse gas into the building materials and energy it needs to grow its branches and leaves.
By removing carbon dioxide from the atmosphere, the tree serves as an indispensable "sink," or warehouse, for carbon that, in tandem with Earth's other trees, plants and the ocean, helps reduce rising levels of carbon dioxide in the air that contribute to global warming.

The Human Factor: Understanding the Sources of Rising Carbon Dioxide
Every time we get into our car, turn the key and drive somewhere, we burn gasoline, a fossil fuel derived from crude oil. The burning of the organic materials in fossil fuels produces energy and releases carbon dioxide and other compounds into Earth's atmosphere. Greenhouse gases such as carbon dioxide trap heat in our atmosphere, warming it and disturbing Earth's climate.
When plants photosynthesize, they use energy from sunlight to turn carbon dioxide from the air into sugars used to live and grow. In doing so, they give off a fluorescent light — a glow that can’t be seen with the naked eye, but that can be seen with the right instruments. More photosynthesis translates into more fluorescence, meaning that the plants are very productive in taking up carbon dioxide. The amount of carbon dioxide taken up by plants is called “gross primary productivity,” and is the largest part of the global carbon cycle.
