It's not the Spanish Armada ...

Can you guess what the unusual formations are in this nanosatellite photo? (The area being imaged is the Myeongnyang Strait - if that helps...)
Which brings us to the subject of "nanosatellites" -

On Nov. 26, 2013, Planet Labs, a private start-up company of San Francisco, CA, announced that it successfully launched its most recent nanosatellites, Dove 3 and Dove 4, into orbit on a Dnepr vehicle (launch on Nov. 21, 2013 from the Yasny Cosmodrome, Russia), completing a series of four prototype nanosatellites in 2013. Those proved successful, enabling the company to quickly follow up with the production of a 28-member network. The launch of Planet Labs' "Flock 1" fleet of 28 nanosatellites in December/January, which will be the largest constellation of Earth-imaging satellites ever launched...
Their "Dove" nanosatellites are meant to be low-cost and rapidly deployable, and capable of taking pictures of Earth that provide a spatial resolution of 3-5 m. — On March 17, 2014, Planet Labs announced that it has confirmed launches for more than 100 satellites over the next 12 months. This full constellation of nanosatellites will allow Planet Labs to image the entire Earth every day. 

It's hard for me to wrap my mind around the concept that technology and data processing have progressed to the point that it is now possible to image the entire planet Earth every day at a resolution of a couple meters.
