This is an image sequence set to an electroacoustic soundtrack.

The video is a slideshow sequence compiled using iPhoto from 90 public domain NASA and ESA images of Mars. (Spacecraft used to obtain these images: Hubble Space Telescope, Viking 1, Viking 2, Mars Global Surveyor, Mars Odyssey, MER-A (Spirit), MER-B (Opportunity), Mars Reconnaissance Orbiter, the Phoenix Lander, and the ESA Mars Express.)

Audio composition, editing and post-processing by Daniel L (2003 - 2008) using Pro Tools on a dual-boot G3 Imac desktop. The source material combines various pre-recorded sound samples together with raw "Space Audio", or "Sounds of Space". These latter are not acoustic in origin, but instead are the sonification, or "direct acoustic translation", of electromagnetic phenomena in Earth's ionosphere and outer magnetic field. This is detected and recorded by satellites; the raw data is then played directly through loudspeakers without any intervening treatment such as pitch or temporal transposition. The website http://www-pw.physics.uiowa.edu/space-audio describes them as "The sounds of space derived from spacecraft measurements obtained by Professor Donald Gurnett and the University of Iowa radio and plasma wave group". They are public domain and are used with permission (by email, 2004) from Professor Donald Gurnett of the University of Iowa, Deparment of Physics and Astronomy.
