Mater Piscis (2024)
Eduardo Kac
Mater Piscis is an artwork composed of four sequential frames that express the life cycle of an aquatic lifeform. Each frame uses ASCII to render an image, adhering to NASA's requirement that only typographic characters be used for this project. Mater Piscis was conceived specifically for integration into NASA's Europa Clipper spacecraft, which was launched on October 14, 2024, to investigate the possibility of life-supporting conditions at Jupiter’s moon Europa.
The first image of Mater Piscis features a fish underwater, setting the context in which this micromovie unfolds. The second frame represents the fish meeting its mate, suggesting the interaction that characterizes courtship. In the third frame we see evidence of reproduction in the form of several offspring, still small and vulnerable. With the relentless drive to propagate life asserted, in the fourth frame we see the lifecycle of the protagonist come to an end beneath the water's surface.
Mater Piscis was etched with an electron beam on a dime-size silicon chip that was bonded to the spacecraft's vault plate. This plate seals an opening in the spacecraft's metal vault holding the electronics for its science instruments, protecting them from Jupiter's dangerous radiation. The microchip is attached to the inward-facing side of Europa Clipper’s vault plate. Each frame of Mater Piscis was etched at a scale smaller than 1/1000th the width of a human hair, which is approximately 75 nanometers.
As it carries out flybys of Jupiter's moon, Europa Clipper will embody "NASA's astrobiology mission of confirming the presence of a vast salty ocean beneath Jupiter’s moon Europa, and, ultimately, determining if Europa is capable of supporting life." The four frames that make up Mater Piscis constitute a GIF animation (top) specially created for this singular Jovian voyage.
In keeping with the water-themed elements that ornate the spacecraft's vault plate, and in accordance to NASA's overarching mission goal of literally searching for an extraterrestrial ocean, Mater Piscis encapsulates the poetics of terrestrial marine life and makes it travel 1.8 billion-mile (2.6 billion kilometers) for around six years, to finally reach the largest planet in the Solar System.
