If humans are going to live someplace other than Earth, the moon seems like a expert selection. It's nearby and could serve as a launchpad for missions to other locations in the solar arrangement. Scientists take long wondered if shadowy crevasses on the lunar surface could be entrances to caverns that could serve as a home for future colonists. New data from Japanese and Usa researchers indicates such caverns do exist.

The moon is a cold, lifeless chunk of rock today, only it was active in the by when the interior was still cooling. Geological activity like lava flows and volcanic action could have carved out tubes and caves similar to features we take here on Earth. The international team examined several dark pits on the moon in what is known as the Marius Hill region. These features are considered some of the best candidates to be the openings to ancient lava tubes.

Researchers from the Japanese space agency JAXA analyzed radar data from the SELENE spacecraft, which was deployed in 2007 to report the moon'due south geology. It turns out the radar instruments on SELENE were also able to provide good show for the existence of lava tubes. Scientists fired multiple radar bursts into the suspected lava tubes, and what they got back was a ii-function echo indicating the interior of the pit has a floor and a ceiling. Several other sites produced the same echo patterns, so there may exist multiple tubes in the region.

The same area surveyed by JAXA also happens to exist where NASA conducted studies with a mission called GRAIL (Gravity Recovery and Interior Laboratory). This mission used a microwave band sensor system to map the gravitational field of the moon. This data can also tell you where there's a mass deficit–areas where there's less mass than the surrounding space. Combining SELENE and GRAIL data, the suspected lava tubes show mass deficits. The team was even able to employ the combined data to guess the size of the sleeping room. The underground cavern is several kilometers long and at least one kilometer alpine.

A massive infinite like this could serve as a location to written report the internal construction of the moon, too equally build a colony. Without an temper or magnetic field, the moon's surface doesn't offering any protection from radiation. Any extended stay on the moon (or Mars, for that thing) would require heavy shielding to foreclose excessive radiation exposure, simply you don't demand to build something on the surface to do that when the moon'southward regolith does the chore fine when yous're underground. There'due south a lot of hype about colonizing Mars, but the moon is looking similar an even more attractive place to start.
