\nESA’s Hertz chamber used for radio testing of large antennas and satellites, taken by photographer Gregor Sailer as part of his Mars Series, which has been awarded at the European Architectural Photography Prize 2017.\n<\/p>\n

\nPart of ESA’s technical heart in the Netherlands, the metal-walled ‘Hybrid European Radio Frequency and Antenna Test Zone’<\/a> chamber is shut off from all external influences.\n<\/p>\n

\nIts internal walls are studded with radio-absorbing ‘anechoic’ foam pyramids, allowing radio-frequency testing without any distorting reflections.\n<\/p>\n
