Organised by Rasa >Smite and Raitis Smits, cofounders of E-Lab/RIXC (Riga Center of New Media >Culture, http://rixc.lv), and Derek Holzer, the acoustic.space.lab symposium >took place on August 4th?2th between the Ventspils International Radio >Astronomy Center (VIRAC) and Riga. Media artists and activists gathered to >explore the interface of art and communications technologies, and to launch >an International Acoustic Space Research Programme. Participants who >travelled for the opportunity to slide around the dish included L'audible, >RadioQualia, Sara Kolster, Robert Adrian X, Radio 90, Siksika Media, >Digibodies, Irational, Makrolab, Clausthome, rigasound.org and >ambientTV.NET. > >In 1993, the Soviet Army withdrew from the Baltic States, revealing the >existence of an espionage centre near Ventspils used to eavesdrop on Western >satellite communications. Of the three antennae at the site, the Soviets >took the smallest dish, but the 16m and 32m dishes were too big to move. >Under pressure from the international radioastronomy community, the army >held off from blowing up RT-16 and RT-32, instead gifting them to the >Latvian government. A handover team did, however, "prepare" the dishes, >throwing metal debris into the mechanics, driving nails through cables, and >pouring acid into the electronics. Thankfully, the antennae were built like >ships--having been drastically overengineered by the Soviet Navy. So, despite >only nominal support from the Latvian government--VIRAC is classed a >"Scientific Company with Limited Responsibility"--enthusiasts from various >Latvian scientific institutes determined the properties of the antennae, >repaired the damage, and transformed them into operational radiotelescopes. >The larger antenna, RT-32 ("Little Star"), is remarkably precise?hrough all >the manoeuverings of the 600 ton structure, the dish distorts less than >0.5mm from its paraboloidal shape. With the installed feed horn tuned to 11 >GHz (2.5 cm wavelength), RT-32 has been used to detect radiation from the >planets, the moon (some due to lunarquakes), the sun and other stars, and >extragalactic sources including possible black holes. It has also been used >for VLBI (Very Long Baseline Interferometry), in which widely separated >telescopes are coupled to produce a giant antenna of a size equivalent to >the distance between them. But lack of funds to repair leaks in the labs and >upgrade the toilet facilities from the Soviet-era wooden hut means that >RT-32 is not overrun by astronomers--leaving it open for takeover by a bunch >of media vagabonds. (In true festival spirit, we brought in a green >portaloo). > >Acoustic.space.lab set up three working groups at RT-32 under the guidance >of Dmitrijs "Dima" Bezrukov. Dima deals with all aspects of the >telescope--electrotechnical, software, making of observations--and is also, if >needed, guard, cook, and driver. He was trusting enough to allow us >unlimited access, and assisted with all types of reception, but ruled out >transmission (since no one had produced the requisite licence). > >RT-32 is mounted on a 25m concrete tower. Just under the dish is the >"submarine" room, complete with portholes and a 15m conning tower that gives >access to the dish surface, the feed horn at the secondary focus, and?fter >a shaky climb up the supporting lattice--the small reflector at the primary >focus. Three groups established residency in various parts of the >superstructure. Makrolab mounted their own L-band (1.5 GHz) feed at the >secondary focus. True to dish's original purpose, they eavesdropped on >communications satellites. Analogue channels on an Inmarsat yielded familial >chatterings in Tamil and a minor drama about a stowaway, which rapidly took >on bureaucratic overtones. In the spirit of their earlier >webstreaming/feedback experiments, ambientTV.NET hoped to place a call and >route it via one of these channels, intercept it and then feed it back, but >logistically this proved impossible. > >Fuelled by borscht and Black Balsams (the other black gold of the Baltics), >the acoustic group scaled the dish and rigged up microphones at the primary >and secondary foci. Dima lowered the dish to zero elevation and scanned the >horizon. Above the wind noise, the mikes picked up rustlings from the Irbene >forest, occasional bird cries, conversations on the ground, and a screeching >handbrake turn. Movement of the dish also generated spectacular sinusoidal >groans and squeaks, consonant in thirds and accompanied by excited squeals >from the submariners. > >The radioastronomy group attempted to observe Venus, Jupiter, and the Sun. >With only a few hour's observation, it proved difficult to isolate any >planetary signals amongst the noise, but data from the solar scans is being >incorporated into Java applets and translated into MIDI by Mr. Snow >(L'audible). Attempts to step down the GHz frequencies into the audible >range yielded, predictably, white noise. But this was food enough for >Clausthome, who spent hours manipulating the nondescript audio into warm, >full industrial soundscapes. > >Back in Riga, the material gathered and processed during the four days at >the telescope was webcast in a 6-hr programme from the LMS Galerija with >remote participation from Kunstradio (archived at >http://acoustic.space.re-lab.net/lab). > >So, "science and art": one massive dish in hand, and we didn't cook up >anything approaching what Alvin Lucier did with a couple of tape recorders. >There was no space for significant dialogue between scientists and artists. >But we hope to use acoustic.space.lab as a launchpad for deeper, more >theoretically and technically informed collaboration. The fact that much of >what is observed is not only very far away not only in space but in time, >the reflexive nature of VLBI measurements being used for geodesy--these are >departure points for more specific and substantial projects. At the close of >the symposium, VIRAC director Edgars Bervalds expressed his delight that the >antenna had been explored in so many ways, adding that, though the antenna >ought to be used primarily for science, "artists can use it to fill the vast >spaces in our Universe that science cannot reach." > >Recordings and theories developed from acoustic.space.lab will feature in >the forthcoming acoustic.space reader (http://acoustic.space.re-lab.net) > >Related programmes: >Sep 8, Riga: Projekt Atol present SIGNAL-SERVER!, an open?ir satellite >audio performance >Sep 24?30, Rotterdam: V2 presents acoustic.space.lab and wiretap discussion >(www.v2.nl/wiretap) >Nov 18, Riga/Venstpils: "Little Star Began to Sing", a symphonic work about >RT-32 by Michael Omer > > > > | | | | | | | | | | | | | | >(a) (c) (o) (u) (s) (t) (i) (c) ( ) (s) (p) (a) (c) (e) > | | | | | | | | | | | | | | >information&comunication channel | for net.broadcasters >http://xchange.re-lab.net (Xchange) net.audio network >xchange search/webarchive: http://xchange.re-lab.net/a/ -----Syndicate mailinglist----------------------- Syndicate network for media culture and media art information and archive: http://anart.no/~syndicate to post to the Syndicate list: <[email protected]> no commercial use of the texts without permission
