On Wednesday, an Atlas V rocket launched into Earth’s orbit, carrying with it what may be the world’s most powerful commercial imaging satellite to date:WorldView-3. This satellite is the latest addition to Earth imaging companyDigitalGlobe‘s constellation, and was built by Ball Aerospace.
Operating from a sun-synchronous orbit, the WorldView-3 satellite operates at a 31cm resolution – meaning it can see data points that just over a foot apart. This enables it to take the highest resolution images possible from a commercial satellite. To give you an idea of what this means, if the satellite were over a baseball stadium, it’d be able to make out home plate and the individual players.
