\nIsolated from the outside world with radio- and sound-absorbing internal walls, the chamber simulates the boundless conditions of space.
\nIts hybrid nature makes it unique: Hertz<\/a> can assess radio signals from antennas either on a local ‘near-field’ basis or as if the signal has crossed thousands of kilometres of space, allowing it to serve all kinds of satellites and antenna systems.
\nThis photo was taken during a visit to ESA’s technical centre in Noordwijk, the Netherlands by artist and photographer Monica Alcazar-Duarte<\/a>: “Once the door of the chamber was opened I was presented with a landscape that could have come from a science fiction film. I know this is not the case of course but the room was incredibly inspiring.”
