Paper Abstract

Laser impulse space propulsion (LISP) has become an attractive concept, due to recent advances in gas laser technology, high-speed segmented mirrors, and improved coefficients for momentum coupling to targets in pulsed laser ablation. There are numerous specialized applications of the basic concept to space science -- ranging from far-future and high capital cost to the immediate and inexpensive, such as: LEO-LISP (launch of massive objects into low-Earth-orbit at dramatically improved cost-per-kg relative to present practice); LEGO-LISP (LEO to geosynchronous transfers); LO-LISP (periodic re-boost of decaying LEO orbits); and LISK (geosynchronous satellite station-keeping). It is unlikely that one type of laser will be best for all scenarios. In this paper, we discuss these most immediate applications, leaving LEO-LISP -- the application requiring the longest reach -- for another venue.
