We propose to develop an artistic program structured around the coordinated creation and implementation of ephemeral geoglyphs. These geoglyphs must be conceived as steganographies, so that they can only be seen and read through the use of an X-Band Synthetic Aperture Radar satellite. The defining characteristic of these space systems is the ability of the X-Band to penetrate dry sand and snow, therefore revealing geoglyphs below them. These geoglyphs remain invisible to any other satellite or aerial image in the visible range. This is a new form of steganography never used before. In our project we plan to use the TerraSAR-X, TanDEM-X and PAZ Synthetic Aperture Radar satellites.
