Planetary defence systems – threat to survival?

Defense & Security Analysis, 2021, vol. 37, issue 4, 492-508

Abstract: The article explains why Weaponisation of outer space may soon be inevitable and that development of space weapons is a serious issue, especially in regard to dealing with sensitive dual-use technology. At the same time, the Earth may be threatened by incoming asteroids and comets, which may endanger humankind’s existence. Hence, it is advisable to develop effective planetary defence systems. However, the article claims that discussed planetary defence technology – kinetic impactor, nuclear explosion, gravity tractor and space tug, laser, and solar collector – have far-reaching dual-use consequences with potential for their weaponisation. Thus, the article argues in favour of greater transparency and surveillance mechanisms for dual-use and arms control. Moreover, the private sector should be involved in discussion since it may be contributing to negotiation processes and can ensure secure research and development, as well as operability of sensitive planetary defence systems.
