Project Janus is a Blue Marble Space Institute of Science initiative that builds ten self-consistent scenarios for Earth and the solar system **1,000 years** from now, then uses those worlds to reason about technosignatures, long-term governance, and human futures.
Page type: future science
The public site curates the scenarios, publications, and a growing gallery of “artifacts from the future” created by contributors - futures.bmsis.org 
# What it is Janus presents **10 named scenarios**, each a compact narrative of political economy, ecology, technology, and space settlement in the year 3025.
1. Big Brother is Watching 1. Wild West 1. Golden Age 1. Living with the Land 1. Transhumanism 1. Sword of Damocles 1. Restoration 1. Ouroboros 1. Deus Ex Machina 1. Out of Eden
The aim is not prediction but a **plural futures** frame: bounding the extremes, illuminating trade-offs, and providing concrete worlds for research and creative work.
# How the scenarios are built
Each scenario is produced with a published Worldbuilding Pipeline: a step-by-step method that starts from human needs and traces implications for technology, environment, and observables. The full pipeline is downloadable from individual scenario pages; for example, the **S3: Golden Age** page links its pipeline on Zenodo - futures.bmsis.org - zenodo.org
# Publications and research context
The foundational paper introduces the 10 scenarios and connects them to **technosignature** search strategies, showing (among other results) that several futures could be spectrally indistinguishable from pre-agricultural Earth despite expansive technospheres - doi.org
A companion study reframes the Kardashev scale as a “luminosity limit,” explores growth trajectories (including hypothetical **stellivores**), and discusses why thermodynamic efficiency bounds long-lived technospheres - doi.org
# Artifacts from the future
Janus invites the public to create **artifacts**—objects that “returned” with you from one of the futures (letters, posters, songs, essays, tools). The **S5: Transhumanism** page already hosts a CC BY 4.0 artifact, *Humanity and Cosmic Consciousness: A Maturity Essay and Classics Project*, with a full text link - futures.bmsis.org - futures.bmsis.org - drive.google.com
If you want to contribute, the call explains scope, the **Phase I** deadline window, and submission form - futures.bmsis.org - forms.gle
# Frequently asked questions
The FAQ clarifies that Janus **does not predict** a single future; it sketches multiple plausible futures for reflection and research. It also defines Artifacts from the Future and how they’re used in exhibitions - futures.bmsis.org
# Who’s behind it
Project Janus is led by **Jacob Haqq-Misra** and **George Profitiliotis** with collaborators including **Ravi Kopparapu** and **Clément Vidal**; the About page provides short bios and context - futures.bmsis.org
