Hello BEST members,

Last week on July 2nd, NASA launched a spacecraft from Vanderberg 
AirForce Base in California devoted to reading carbon dioxide 
concentrations in the atmosphere. The spacecraft is called Orbiting 
Carbon Observatory-2 satellite (OCO-2). The original OCO was launched in 
2009 and crashed into the Pacific Ocean shortly after.
OCO-2 is estimated to makes its way into polar orbit with other 
Earth-surveying satellites 438 miles above Earth's surface about six 
weeks from July 2nd. Once in orbit OCO-2 will be using a grading 
spectrometer to measure carbon dioxide with an accuracy of 1 part per 
million. OCO-2 will be able to move over all of Earth in about 16 days 
and has the capability to measure carbon dioxide concentrations 24 times 
within 1 second. This will lead to a large amount of information on CO2 
sources and sinks. In other words, information on where CO2 is being 
produced and where it is being taken away from the air.
The launching of this satellite is extremely important to carbon policy 
issues. The data obtained from the satellite will allow for more 
accurate information about where the most carbon is coming from and how 
much of it exactly contributes to global warming. Also it will make 
sound information available to scientists and decision makers which will 
hopefully lead to better decision making in regards to carbon policies 
and climate change.
