On Satellites

Inside a Startup's Plan to Turn a Swarm of DIY Satellites Into an All-Seeing Eye | Wired Science | Wired.com: Of the 1,000 or more satellites orbiting the planet at any given time, there are perhaps 100 that send back visual data. Only 12 of those send back high-resolution pictures (defined as an image in which each pixel represents a square meter or less of ground), and only nine of the 12 sell into the commercial space-based imaging market, currently estimated at $2.3 billion a year. Worse still, some 80 percent of that market is controlled by the US government, which maintains priority over all other buyers: If certain government agencies decide they want satellite time for themselves, they can simply demand it. Earlier this year, after the government cut its imaging budget, the market’s two biggest companies—DigitalGlobe and GeoEye, which between them operate five of the nine commercial geoimaging satellites—were forced to merge. Due to the paucity of satellites and to the government’s claim on their operations, ordering an image of a specific place on Earth can take days, weeks, even months.
