The debate about whether we should spend more on reducing poverty and improving the environment – both laudable objectives – rather than sending people into space ignores the behemoth in the room: global defence spending of more than $2 trillion in 2022. NASA’s budget is some $24 billion, around 1 per cent of that total. Those calling for a reduction in space exploration are barking up the wrong tree(Letters, 1 October).
