the scale of HOME In the opening monologue of Alfonso Cuarón’s 2013 film Gravity, five sentences set on a black backdrop convey the hostile conditions humans would encounter in the Thermosphere and beyond: 1 At 600km above planet earth, the temperature fluctuates between +258 and -148 degrees Fahrenheit. 2 There is nothing to carry sound. 3 No air pressure. 4 No oxygen. 5 Life in space is impossible. 9 Artificial satellites are not living organisms. They thrive without air pressure or oxygen. On low orbit [LEO], Middle orbit [MEO], and geosynchronous [GEO] zone, their positions ensure that daily blizzards of data would reach home. But, if ‘a massive solar storm disrupting satellite communications, a cyber attack partially disabling the GPS system, and debris knocking out Earth-monitoring satellites’ 10 occurred, it could cause total disruptions to our way of life. Transport, energy, and computer services will be affected and fear will engulf our sense of existence. People would start to believe that life without artificial satellites would be impossible to sustain. Then, bespectacled by digits and microchips, it would take days for our analogue processes of design to respark. p 9 Cuarón, Alfonso, director. Gravity . Warner Bros.
