Once More, Into the Unknown

Novelists have "It was a dark and stormy night." For planetary scientists, the equivalent cliche is, "We expect to be surprised." The story of every new space mission seems to begin that way. No matter how intensely researchers study some solar-system object, no matter how they muster the best resources available on Earth, they are inevitably caught off-guard when they get to study it up close for the first time. And no matter how worn and familiar that cliche may sound, it also rings true e

50 Years Later, Still Processing Apollo 8's Message of Hope and Desolation

Some two billion years ago, the first photosynthetic algae evolved the ability to respond to light—the brilliant Sun by day, the spectral Moon by night. Around 700 million years ago, primitive eye-pits appeared; then, during the Cambrian era, arthropod-like creatures gazed at the sky through true eyes, sensing the lunar rising and setting with their arthropod-like comprehension. So it continued, into the succeeding chapters of life featuring mammals, primates, hominins, and Homo sapiens, the

That song has popped up in my brain again recently, but in a very different and more majestic context. We are entering a new stage in the exploration of the solar system, one that inverts the theme of much that came before. Big is out an
