Not sure how I missed this one, but Planet Labs, a startup called founded by NASA alumni, is planning to launch a 28-satellite constellation in the coming weeks that will take 3-5 m images of the Earth. That’s not a groundbreaking resolution, and I haven’t heard anything about return time. But given the number of satellites, it should be a good product.
Plus, there doesn’t appear to be any restrictions on who can buy the data, something that isn’t always the case with other satellites partially built using defense money. Cost per image is still unknown. (Some outlets, including the New York Times, have reported that Planet Labs will be providing imagery for free. I can’t find any evidence of that apart from a note on their site about the data being “open,” which is different than “free.”)
