Economic Challenges of Financing Planetary Defense,obal institution. The general conclusion reached is that the evolution of new types of space technologies that might be developed for other purposes such as space debris removal, on-orbit servicing, etc. – may represent the most logical way forward.

European Operational Initiative on NEO Hazard Monitoring,d by the other NEO-related programs of the European Commission. A major achievement in this respect has been the inauguration in May 2013 of the ESA NEO Coordination Centre located at ESRIN (Frascati, Italy), whose services and operations are discussed in detail.

There is increasing international agreement that a process for active removal of orbital debris elements – once they are clearly defi

Finally in the operational phase, the challenge was to operate four spacecraft with the funding for one, to solve serious anomalies, and to extend the spacecraft lifetime, now seven times its initi

Stuart Allardyce,Peter Yates,Sharron Warehamaporated material creates a large reaction force that alters the asteroid’s orbit. Both standoff (DE-STAR) and stand-on (DE-STARLITE) systems are discussed. The baseline standoff system is a DE-STAR 3 or 4 (1–10 km array) depending on the degree of protection desired. A DE-STAR 4 allows initial enga
