If humans are going to alive someplace other than Globe, the moon seems like a practiced pick. Information technology's nearby and could serve as a launchpad for missions to other locations in the solar system. Scientists have long wondered if shadowy crevasses on the lunar surface could be entrances to caverns that could serve as a home for hereafter colonists. New data from Japanese and U.s.a. researchers indicates such caverns practise exist.

The moon is a common cold, lifeless chunk of stone today, but it was active in the past when the interior was yet cooling. Geological activity similar 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 Loma 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 information from the SELENE spacecraft, which was deployed in 2007 to study the moon'south geology. Information technology turns out the radar instruments on SELENE were too able to provide good evidence for the existence of lava tubes. Scientists fired multiple radar bursts into the suspected lava tubes, and what they got dorsum was a two-part echo indicating the interior of the pit has a floor and a ceiling. Several other sites produced the aforementioned echo patterns, so there may be multiple tubes in the region.

The aforementioned area surveyed by JAXA also happens to be 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 tin also tell yous where there'due south a mass deficit–areas where at that place's less mass than the surrounding space. Combining SELENE and GRAIL data, the suspected lava tubes bear witness mass deficits. The team was even able to utilize the combined data to estimate the size of the bedchamber. The secret cavern is several kilometers long and at least i kilometer alpine.

A massive infinite like this could serve every bit a location to study the internal structure of the moon, as well every bit build a colony. Without an atmosphere or magnetic field, the moon's surface doesn't offer whatever protection from radiation. Whatever extended stay on the moon (or Mars, for that matter) would crave heavy shielding to prevent excessive radiation exposure, simply yous don't need to build something on the surface to practice that when the moon's regolith does the job fine when you lot're underground. There's a lot of hype about colonizing Mars, merely the moon is looking like an even more attractive identify to start.
