  • When it comes to space colonization, Mars is at the forefront of modern exploration.

  • Meanwhile, our nearest celestial neighbor - the Moon - is seemingly overlooked.

  • And that's, in part, because the Moon isn't exactly a haven for humanity.

  • The lunar surface is covered with dead volcanoes, massive craters and potentially poisonous dust.

  • It's also constantly bombarded by space rocks raining down on its surface due to its very

  • thin and weak atmosphere known as an exosphere.

  • On top of that, this ultra thin layer of gases

  • doesn't provide any protection from the sun's radiation.

  • But some scientists believe this wasn't always the case.

  • Recent NASA findings show that there might have been a time when the Moon had a prominent

  • atmosphere, and it could make the Moon a stronger contender for colonization.

  • Billions of years ago, after the formation of the inner solar system, it's believed,

  • that the young planets and the moon were pummeled by space rocks

  • and other leftover planet-building material.

  • The period known as the Late Heavy Bombardment or LBH is thought to have lasted millions

  • of years, and damage from this violent period was seen in craters on some of the inner planets and the Moon.

  • There, the LBH triggered a series of volcanic eruptions.

  • Lava filled the lunar craters, creating seas that stretched for hundreds of kilometers across its surface.

  • During this period, it's thought that the lunar lava emitted gas components or volatiles

  • like carbon monoxide, sulfur, hydrogen and oxygen.

  • As the lava spread, the volatiles accumulated and formed a transient atmosphere.

  • The ancient atmosphere was believed to be much thinner than Earth's current atmosphere,

  • but 1.5 times thicker than Mars' current atmosphere.

  • The eruptions lasted for about 70 million years, and it's estimated that trillions of

  • gallons of water was released during this period.

  • As the atmosphere started to thin out, the volatiles were either lost to space or became part of the surface of the Moon.

  • Researchers believe it's possible that a significant amount of water may have made its way to the

  • lunar poles and could be trapped in permanently shadowed regions.

  • In fact, NASA's new analysis quantifies a source of volatiles based on lunar samples collected during the Apollo missions.

  • And these volatiles could provide key resources - like water, air and fuel

  • - for extended moon missions and beyond.

  • So while Mars is still a frontrunner when it comes to colonization, revelations about

  • the Moon's past and its potential presence of water continue to prove that there is still

  • a lot more lunar exploration needed before we count the Moon out.
