The concept of self-replicating spacecraft, as envisioned by mathematician John von Neumann, has been described by futurists and has been discussed across a wide breadth of hard science fiction novels and stories. Self-replicating probes are sometimes referred to as von Neumann probes.
Freeman Dyson in 2005. Astrochicken is the name given to a thought experiment expounded by theoretical physicist Freeman Dyson.An Astrochicken is a small, one-kilogram spacecraft, a self-replicating automaton that could explore space more efficiently than a crewed craft could due to its innovative mix of technology.
A quantitative engineering analysis of a self-replicating variation on Project Daedalus was published in 1980 by Robert Freitas. [9] The non-replicating design was modified to include all subsystems necessary for self-replication. Use the probe to deliver a seed factory, with a mass of about 443 metric tons, to a distant site.
The first quantitative engineering analysis of a self-replicating spacecraft was published in 1980 by Robert Freitas, [56] in which the non-replicating Project Daedalus design was modified to include all subsystems necessary for self-replication. The design's strategy was to use the probe to deliver a "seed" factory with a mass of about 443 ...

Discrepancy of the lack of evidence for alien life despite its apparent likelihood This article is about the absence of clear evidence of extraterrestrial life. For a type of estimation problem, see Fermi problem. Enrico Fermi (Los Alamos 1945) The Fermi paradox is the discrepancy ...
He contemplated how humanity could build a small, self-replicating automaton that could explore space more efficiently than a crewed craft could. He attributed the general idea to John von Neumann , based on a lecture von Neumann gave in 1948 titled The General and Logical Theory of Automata .
