I have a new story published in The Guardian:

'Launching equipment into space is an expensive business: it costs $10,000 (£6,300) to lift every 0.45kg (1lb) of stuff into orbit. Making things smaller and lighter is, therefore, a natural route to reducing the cost of launching a spacecraft. It is no surprise then that the principles of nanotechnology - and the potential to reduce the mass and size of spacecraft and payloads - are focusing the minds of space engineers. ...'
