GRAIL and the Mystery of the Missing Moon




NASA’s GRAIL mission started its lunar probe late in 2011 to uncover some of the mysteries buried beneath the surface of the Moon –even, perhaps, a long-lost companion. According to recent scientific speculation, the Earth once had two moons gracing our night skies.

“It’s an intriguing idea,” said David Smith, GRAIL’s deputy principal investigator at MIT. “And it would be a way to explain one of the great perplexities of the Earth-Moon system – the Moon’s strangely asymmetrical nature. Its near and far sides are substantially different.”

The Moon’s near side, facing us, is dominated by vast smooth ‘seas’ of ancient hardened lava. In contrast, the far side is marked by mountainous highlands. Researchers have long struggled to account for the differences, and the “two moon” theory introduced by Martin Jutzi and Erik Asphaug of the University of California at Santa Cruz is the latest attempt.

Scientists agree that when a Mars-sized object crashed into our planet about 4 billion years ago, the resulting debris cloud coalesced to form the Moon. Jutzi and Asphaug posit that the debris cloud actually formed two moons. A second, smaller chunk of debris landed in just the right orbit to lead or follow the bigger Moon around Earth.

“Normally, such moons accrete into a single body shortly after formation,” explains Smith. “But the new theory proposes that the second moon ended up at one of the Lagrange points in the Earth-Moon system.”

  1. That’s no moon, it’s a space station!

    • We know Phobos is 1/3 hollow, maybe able to contain some kind of atmosphere inside and has geometric voids. Many people believe it to be artificial because its formation defies simple explanation and went against the standardize theory. I personally believe it’s a natural structure and literally a proto-moon. My best explanation I can figure out for the creation of our moon is mass eruptions take place on Mars, its two moons smash together and eventually forms into the moon we see today. Mars two moons were specifically designed by God for this purpose. Yet I’m not totally convinced this is how the moon is made but it’s better than the “Mars size object colliding with Earth” planetesimals theory. Our moon is very mysterious indeed.
