Laser Ablation Requirements for Practical Acceleration to the Asteroid Belt, and Beyond. a Concepts in the Works Study

Authors: Andrew Beckwith

The rocket equation and the low exhaust velocity of chemical fuels are at the root of the high cost of most NASA approved current inter planetary travel platforms. Laser boosting of space crafts are a way about this problem If sails are used for travel to the asteroid belt and beyond with incident laser beams providing acceleration, prior to interstellar power, the problem of how to keep a constant laser power flux to the accelerating space craft necessitates a re thinking of where to place lasers, i.e. the Lagrange points of the Earth-Moon system, as well as batteries of lasers in the Lagrange points, for continual application of power for applying sail drives . The conclusion, as outlined by the author, is that major development of stable large scale lasers, far in excess of performances obtained for the MIRACL 3um laser are essential for any practical development work taking place.

Comments: 5 pages, no figures. For evaluation of the new journal IJAI, as an elaboration of material presented by the author in Scottsville, Az, in November 9 2009, at AIBEP.org biennial meeting.
