ETERNAL MEMORY : LONG - DURATION STORAGE CONCEPTS FOR SPACE
Résumé
Eternal memory is information encoded in some medium and capable of surviving in storage for a very long time This
paper explores the rationales for an eternal memory concept for space and also develops three concepts for it using
product development methodology. Historical development drivers for data storage are storage density and processing
speed, while longevity of data has been limited to decades. Recent advances in storage technologies, such as optical
storage and DNA storage, allow data storage for timescales of millions to billions of years. Eternal memory concepts
for space are of interest to initiatives such as Lunar Mission One, the Long Now Foundation and the Human Document
Project. The recent technological advances and the focused initiative of these projects produces a gap for the
development of eternal memory concepts for space. The study first identifies potential stakeholders, such as Lunar
Mission One, the Long Now Foundation and the Human Document Project, and categorizes stakeholders by
motivation. Stakeholder needs are interpreted from statements of motivation. Stakeholders want an eternal memory
concept to encourage global public engagement, to move humanity toward becoming a dual-planet species, to embrace
and constrain the information age, and to allow storage of information for a very long time. These needs are arranged
hierarchically for each stakeholder and the most prevalent needs are selected. Metrics are then assigned to each need.
A suggested storage technology and storage location are recommended for each case study. Each storage concept
attempts to add value to stakeholders, addressing financial, scientific, technological, and socio-cultural needs.
