A New Zealand-based lawyer specialising in international space law says there are no laws preventing the mining of asteroids for commercial or scientific gains and she expects to see the practice begin within the next 10 years.
Christchurch lawyer Dr Maria Pozza said no legislation could restrict the practice as no one has legal jurisdiction over outer space.
A Bloomberg article published last week stated that NASA had identified around 12,000 space rocks orbiting Earth and a small group of investors had a novel plan to mine them for fun and profit.
However, the article stated that mining the asteroids could be illegal, citing an international treaty regime, including the Outer Space Treaty of 1967, which forbids claims of national sovereignty in space - a point disputed by Pozza.
