... by ultrafast lasers particularly attractive for propulsion applications. We introduce the "Laser Accelerated Plasma Propulsion System" LAPPS, and demonstrate its potential propulsive capability by addressing an interstellar mission to the Oort ... . In both instances we identify the major technological problems that must be addressed if this system is to evolve into a leading contender among the advance propulsion concepts currently under consideration ...

... Abstract It is the current practice to largely construct space systems, including infrastructure systems, from bespoke components designed especially for the system as part of its overall development. Where "off the shelf" components ... generally an originally bespoke legacy from a previous project. A largely untried approach for space systems is the development of generic components and subsystems at the Tier 1 level, that are ...
