Cities and Memory - remixing the world episodes

  • 2452: Project Echo
    This vintage recording recently found in the NASA Jet Propulsion Laboratory audio archives comes from NASA's first successful communications satellite, Project Echo. The project involved bouncing radio signals off a 10-story-high, aluminum-coated balloon orbiting the Earth in 1960. This form of “passive” satellite communication – which they dubbed a “satelloon” -- was an idea conceived by an engineer from NASA’s Langley Research Center and a project managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. JPL sent and received signals through two of its 85-foot-diameter antennas at the West Coast Goldstone tracking station in the Mojave Desert.

  • 2450: SLS rocket test fire
    The Space Launch System (SLS) is an American Space Shuttle-derived super heavy-lift expendable launch vehicle. It is part of NASA's deep space exploration plans including a crewed mission to Mars. Recording by NASA.

  • 2448: Ultra-cold liquid helium
    If you're squeamish, you may not want to listen to the strange whistle of ultra-cold liquid helium-3 that changes volume relative to the North Pole and Earth's rotation. When ultra-cold liquid helium-4 was squashed through an array of tiny apertures, a phenomenon occurred in which the helium-4 repeatedly sped up, slowed down and vibrated. This produced a "quantum whistle" -- a whistling sound that went from high to low.

  • 2447: Wailing Leonids
    Tracks left behind by the November 2000 Leonids shower, as detected by ESA scientists.
    Each time a meteor crosses the atmosphere, it leaves behind a short trail of ionised particles. This trail reflects high-frequency radio signals from stations around the world for just a few seconds. The motion of the meteor trail due to the upper atmosphere winds changes the frequency of the reflected signal (Doppler effect). You 'hear' the trail as it is blown around by the winds before it is eventually dispersed.

  • 2446: International Space Station Alarm
    Ever wonder how the International Space Station alarms sounds? This emergency alert is the last thing astronauts on the ISS ever want to hear as they work 400 km above Earth in the vacuum of space.This sound was sent to us by the Columbus Control Centre, near München, Germany, the operations centre for ESA astronauts and the Columbus laboratory, part of the orbiting weightless research centre.
    The alarm is sounded on the International Space Station to alert astronauts to life-threatening emergencies such as loss of pressure or fire. The astronauts would immediately convene near their Soyuz spacecraft that serve as lifeboats, but these kind of emergencies are extremely rare and the alarm has sounded only a handful of times despite the Space Station having been inhabited since 2000.
    Most astronauts on a six-month space flight will only ever hear the sound during a practice session.
    Regular 'fire-drills' are performed to make sure that even in a worst-case scenario everybody knows what to do. Mission controllers from the international partners that run the Space Station in Russia, USA, Europe and Japan re-enact scenarios with the astronauts in space. In critical situations the teams on ground need to communicate efficiently, act quickly and coordinate a solution between each other and the astronauts flying 400 km above them.

  • 2445: Rosetta end of operations
    Spacecraft Operations Manager Sylvain Lodiot confirms loss of signal (LOS) and end of Rosetta operations at 13:19 CEST, 30 September 2016, via the voice loop in the Main Control Room at ESA's space operations centre, Darmstadt, Germany.

  • 2444: Recording of Mars Rover
    "An exploration of the sounds of space exploration - made here on Earth. ESA's ESTEC facility is where spacecraft are prepared for travel.
    Here are sounds recorded of prototypes of ESA's upcoming ExoMars rover, made in the Planetary Robotics Lab. This includes sounds as we would actually hear them (albeit in Earth atmosphere), as the rover prototype tests its wheels and disembarks from the lander mock-up and traverses some simulated Martian gravel.
    It also includes some electro-magnetic radiation, converted to audible sound.
    In addition, I've included sounds of the popping of nitrogen valves from the Materials & Electrical Components Laboratory, involved in a materials test."
