Will humans ever travel to the stars? Tim Folger considers the question in the January issue of National Geographic magazine, which kicked off our 125th anniversary year’s theme of exploration. “To get to the stars”, Folger writes, “we’ll need many new materials and engines but also a few of the old intangibles. They haven’t vanished. In fact … in the conversation of certain dreamer-nerds, especially outside NASA, you can now hear echoes of the old aspiration and adventurousness – of the old craziness for space”. That old craziness appears on the cover itself, where Stephan Martiniere’s art shows a 22nd-century dream: an unmanned probe powered by nuclear fusion exploring a new solar system, after traveling several decades from Earth at 100 million miles an hour.
