Space Seed is an ideological experimentation of a digital afterlife management system for future planetary inhabitants. It's using speculative design to investigate and reverse engineer the Panspermia theory.

This sophisticated apparatus will engineer our digital life data into special bacteria or extremophiles in which our digital afterlife, our wishes for the next life and our biological identity are encoded.

A capsule will protect these bacteria and follow its deep space journey towards a target planet.

Space Seed conserves the memory of each individual of our technological civilization and provides a record for any future inhabitants or visitors to understand the Planet Earth and its ancient civilizations. It is just like a message in a bottle thrown into the ocean: Space Seed is an open message for the visitor of the future.

The new circle of Panspermia has finished its reverse engineering process and is patiently waiting for our future planetary descendants to discover its origin.

This project is intended to immerse the audience into the world of speculative questioning and to challenge the definition of life, its origin, its present, and future.

Insulation maybe be used to thermally isolate the radiator panel from the spacecraft.


Material Choices:

+ Material of this Radiator fins: stiffened aluminum plate (source: http://www.slideshare.net/IngesAerospace/spacecraft-thermal-control-6-radiators


+ Carbon fiber (insides of the cube made from this to provide strength). Surrounded by thin titanium/aluminium layer.. and finally a coating of heat resistant material. 

Strong materials that can handle and distribute the temperature and pressure of  space and other planets. Spacecraft shielding is defined as the outer layer of a satellite or spacecraft that protects it against micrometeorite and orbital debris (MMOD), radiation damage, and re-entry temperatures. 

aluminium shielding, hydrogen-rich plastics and rare-earth-doped rubber are effective in attenuating cosmic rays to make Electromagnetic interference (EMI) shielding and thermal management.

The tensile strength of carbon nanotubes greatly exceeds that of other high-strength materials.

 5, Reaction wheels (4 of them) / Gyroscopes 




 An electrically-powered wheel aboard a spacecraft. Typically, three reaction wheels are mounted with their axes pointing in mutually perpendicular directions. To rotate the spacecraft in one direction, the appropriate reaction wheel is spun in the opposite direction. To rotate the vehicle back, the wheel is slowed down. Excess momentum that builds up in the system due to external torques must be occasionally removed via propulsive maneuvers. 


One of Kepler’s reaction wheels, manufactured by Goodrich Corporation.  The reaction wheels are gyroscopes that keep the Kepler spacecraft pointing in a fixed direction.  The telescope, which has four reaction wheels, requires three to be operational at a given time to maintain its stable pointing.

      (Cubesate use small chips for ground communcation)

  • Communication system could consider to use the Swisscube , it's small and efficient.


        • Design decisions:

          1. A signal transmission/relay system that communicates to these seeds and transmits back info to earth via satellite. This would ensure the size of the seeds remains minimal, as well as we are kept informed about the current status of the seed and if it has been planted.

          2. The seed itself is sent to the planet through a slingshot mechanism, to a pre-decided location, say on Mars (decided on bases of high resolution pictures taken), ensuring  the size of the seed remains minimal, and no motor-mechanism is need for it to be 'planted' in a specific location. It then would communicate back using an idea like Project Loon (from Google). Every now and then, these floating balloons would  communicate with the seeds when in range, and then would relay their status. The floating balloons/drones (flying actually, since there's no constant wind source on Mars as on Earth), would transmit the status to satellites with short radio bursts, ensuring energy efficient communication.
