Satellite images raised speculation about Venezuela’s military capability

Wheelbarger said he collects publicly available images from 28 satellites operated by several commercial-satellite companies, including Maxar Technologies, Planet Labs, Airbus Defence and Space, BlackSky, Capella Space, ICEYE, SkyFi, European Space Imaging, Apollo Mapping, Satellite Imaging Corp. and L3Harris Geospatial. He and colleagues also access images from ground cameras – sometimes by hacking into them. He employs another video method he declined to discuss on the record, gleans information from human sources around the world and follows aircraft movements with flight-tracking sites.
