After more than seven years of development, MethaneSAT recently launched from Vandenberg Space Force Base in California. A collaboration between the Harvard John A. Paulson School of Engineering and Applied Sciences, Harvard-Smithsonian Center for Astrophysics, the Environmental Defense Fund and other partners, MethaneSAT will be capable of spotting methane emissions from space, producing data from high-resolution images that can cover hundreds of square kilometers at a time.
