Agulhas Drifter
Agulhas Drifter est un nouveau projet d’art médiatique passionnant qui présente les conditions des vagues en haute mer aux visiteurs de la galerie. En juin 2018, Sai Keener a lancé une bouée en verre soufflé personnalisée le long de la rivière Agulhas au large de Durban, en Afrique du Sud, et a créé un système lumineux et sonore immersif qui répond aux formes d’onde des satellites en temps quasi réel. La bouée enregistre le tangage, le roulis et l’accélération verticale des vagues, enregistre la température de surface de la mer et surveille les courants. Ces données sont transmises par satellite toutes les huit heures. L’installation de la galerie utilise les dernières données de mouvement des vagues en utilisant une sculpture cinétique pour projeter une ligne d’horizon changeante de lumière laser à travers la salle de la galerie afin de visualiser les conditions océaniques actuelles.

Satellarium II
Sun Outage is a degradation or temporary interruption of satellite signal caused by solar radiation. In these moments satellites occur to be in between the Sun and the Earth, producing with their shadows an invisible eclipse. Satellarium II shows these astronomical events through a variation of visuals and sounds in the room in which it is exhibited. The installation consists of a set up of multi channel surround speakers and graphics projected on a disk above the viewers, representing the fragment of the visible sky from the location of the artwork. Visuals and sounds are based on real time tracking of the satellites position and magnitude (brightness of a satellite as it appears in the night sky from Earth). The gradient on the background of the projection represents the sun and it is related to its real-time position in the sky.

Satellite Daylight
Satellite Daylight is an interactive light installation formed by a trapeze of 24 high-voltage neon tubes tapering upwards, created by fabric | ch – a studio for architecture, interaction and research dedicated to investigating contemporary space based in Lausanne. The installation is connected to data collected in real time from online weather stations and meteorological satellite maps, which therefore translate actual global light conditions picked up by satellites orbiting the earth at the latitude of Basel into an endless loop of perceivable electrical intensity.

Orbits
“The aesthetics of man-made objects in space, their appearance and especially their orbits are transformed into a minimal audiovisual performance, showing the poetic dance satellites and their trash perform while revolving around us. Seemingly chaotic paths mutate to amazing patterns of an almost organic nature—all of it due to pure physical necessity. When we started working with global satellite data, their information was based on a website maintained by the US Air Force. Yet after some time, based on information from the Union of Concerned Scientists, we discovered that some objects were missing. Fortunately the data on classified satellites is generated by enthusiastic amateur astronomers observing the night skies.” Quadrature

Supraspectives
In the process of creating Supraspectives, the artist duo Quadrature has gathered the data of 590 (recent & former) spy satellites, whose trajectory the installation follows. A third of them can be considered space trash, as they are obsolete or damaged, but still, they continue overflying us. The installation calculates the paths of all those satellites in real time and speculatively reconstructs the view they are capturing, offering artistically intervened images of what the satellites could be observing. Mainly satellites passing near the exhibition venue are selected, combined with other specially interesting or suggestive satellite images. Additionally, a specifically built motorized antenna on the roof connects live with the satellites overflying Tabakalera, transforming their real radio signals into sound. Everytime the installation connects with a satellite, the screen shows the data relative to it, such as country of origin or year of launch.

Beyond Cassini
“BEYOND CASSINI” uses this narrative to celebrate the accomplishments of one of the most successful and beloved Satellites in space exploration history. As Cassini begins its final flight into Saturn’s upper atmosphere with a mission of disintegration, visuals flash back through time giving viewers highlights of this dying satellite’s life.

Positions of the Unknown
At the very beginning of space exploration the infrastructure to monitor the whole sky was not yet developed. So in order to find out whether foreign countries launched objects, the US government started to train citizens to observe and detect possible artificial satellites. Scattered over the allied world, these amateur scientists played a crucial part in keeping track of all men-made technology orbiting earth, until “Operation Moonwatch” was discontinued in 1975 […] “Positions of the Unknown” locates the current whereabouts of these mysterious objects by simply pointing at them as they revolve around Earth. Missing the legal proof, those unidentified artefacts remain entities of pure speculation, secret companions of us and our planet. Even so they have been sighted several times and their ubiquitous presence is therefore somehow validated, they linger in a state between existence and non-existence. Quadrature’s 52 small machines constantly follow their paths and serve as silent witnesses of the unknown.

SATELLITES
“By 2020, it is predicted some 6000 satellites will be orbiting the earth. From climate monitoring to communications, satellites are functioning to open up new horizons for us all. Our proposal for the Dubai Expo UK Pavilion, SATELLITES, aims to articulate and celebrate Britain’s unique contribution to this remarkable milestone, demonstrating how imagination, innovation and collaboration can change and improve lives around the world.” Steven Chilton Architects
