Interstellar Exploration Mission Concept

Preliminary concept study by Kadri Gurra exploring robotic interstellar exploration of the Alpha Centauri system. Records an initial fusion mothership and sample-return concept, mass and cooling challenges, and the later choice of a small laser-driven sail probe for a flyby. Includes sketches and illustrative calculations. The 50-year flight and 10-gram payload are unverified targets. This is a discussion synthesis, not a validated engineering design or peer-reviewed result. Prepared with ChatGPT assistance for drafting, calculations, and sketches; independent technical review is needed.
