What has the space race done for us?
Space exploration is a reward in itself: giving us glimpses of Martian vistas and the birth of stars near the heart of our galaxy.
But the question of how spacebound technologies benefit the wider world continues to be raised. The answer is 'quite a lot', with spinoffs from NASA-developed tech finding applications far beyond non-stick frying pans.
To coincide with NASA making a host of new technologies freely available for commercial use, we look back at the practical technologies to emerge from the space agency's research in recent decades.
