The satellite company Planet is used to breaking records. In 2014, a rocket exploded with a payload of the company’s satellites inside—26, the biggest loss ever.

I was commissioned to write the essay for Mishka Henner‘s solo show, Black Diamond, at Carroll/Fletcher Gallery, London. The exhibition will run until 31st May, 2014. Excerpt from the essay : If linear perspective centred the World on the Earthly beholder – rendering the artist, viewer or owner of a painting as master of all they purveyed – then its replacement, a tumbling or “dynamic viewing space” imposes a kind of vertigo on the subject, causing us to misjudge the social and political ground of our perceptions. Henner’s 51 US Military Outposts places viewers in the position of Gods above a toy-like World, the fidelity of which is wholly reliant on the resolution of the sourced images. In line with his Feedlots and Oil Fields series, the resolution of the images – appropriated from Google Earth, and painstakingly stitched together – gives us a clue as to where their socio-political ground is located. Just as a pixel attains significance only within the context of the image grid, so the relatively plain surface of Earth is politically meaningless, is without form and void, until its geometries and textures, its biological traces and material densities, are caught and defined in the vast, inconceivable, territories of the database.

Scientists today who study polar sea ice conditions rely on satellite records reaching back to 1979. But soon, data scientists hope to extend the look back by another decade or more. Researchers at NSIDC and NASA have shown that the oldest Earth observing satellite data can be made to yield new information, adding significantly to the view of Earth's climate history.

When NASA launched the first Nimbus satellite in the 1960s, they also launched an era of Earth observations from space. While the early Nimbus satellites provided meteorological and other observations, methods did not yet exist to detect features such as the margins of the sea ice cover in the Arctic and Antarctic. Even if they had, the limits of computer processing in those days would have made quantitative analysis unfeasible.
