WASHINGTON: California-based Planet Labs has expanded restrictions on accessing its imagery of the Middle East to prevent adversaries from using it to attack the US and its allies, a sign of how the expansion of commercial space business can impact conflicts. Planet, which operates a large fleet of Earth-imaging satellites and sells frequently updated images to governments, companies and media, told customers on Monday that it was extending restrictions to a period of 14 days from a delay of four days imposed last week.
