Serving Earth
identifying "fire hotspot pixels" on satellite images. Today SERVIR's fully-automated fire detection system notifies field teams and rapidly guides them to the site using GPS. Firefighters can reach a fire (often in a remote area) and fight it while it is...
Blast Off for Orbital Express
Florida, soaring to low Earth orbit to begin an intensive, three-month demonstration of automated rendezvous and docking capabilities. If the mission is successful, NASA engineers say, those capabilities could become a critical element of America's future space endeavors, providing an...
