NASA Found 'Definitive Evidence' That There's Water Ice on the Moon

In what will go down as a major milestone in space exploration, NASA has confirmed that frozen water has been found on Earth's Moon. The scientists who made the discovery don’t know how long the ice has been there, but they say it might be ancient.

It could be used by future lunar explorers, according to a NASA statement: “With enough ice sitting at the surface—within the top few millimeters—water would possibly be accessible as a resource for future expeditions to explore and even stay on the Moon, and potentially easier to access than the water detected beneath the Moon’s surface.”

This is the first “direct and definitive evidence” of ice on the Moon’s surface, according to their findings, published in the Proceedings of the National Academy of Sciences. Prior evidence of lunar ice has been extensive but ambiguous, and some of the past evidence of ice turned out to be something else, like hydrogen-enriched minerals, reports Scientific American.

The ice, detected by NASA’s Moon Mineralogy Mapper (M3) instrument, is shown in blue in the below images. At left is the Moon’s south pole, and at right is the north pole.

Darker hues represent colder temperatures, and as you can tell from the image, the ice was found in the coldest, darkest areas of the Moon's poles—in most cases, the shadows of craters. Sunlight never reaches these areas, and the temperature remains at or below -250°F.

M3 has been aboard the Indian space agency's Chandrayaan-1 spacecraft since it launched in 2008. It has been used to collect data and find signature molecular absorption features in near-infrared light, allowing the device to tell liquid water apart from vapor and solid ice. It also confirmed previous findings.

Last year, researchers used satellite imagery to identify droplets of water preserved inside glass beads within the Moon’s volcanic deposits. NASA also reported in 2009—after intentionally slamming probes into a crater to create a plume of debris that could be studied—that the Moon’s south pole did in fact contain ice.

However, conclusions from that mission were indirect because they were based on modeling, according to the new study's lead author, Shuai Li of the University of Hawaii at Manoa.

Does the Full Moon Really Make People Act Crazy?

Along with Mercury in retrograde, the full moon is a pretty popular scapegoat for bad luck and bizarre behavior. Encounter someone acting strangely? Blame it on the lunar phases! It's said that crime rates increase and emergency rooms are much busier during the full moon (though a 2004 study debunked this claim). Plus, there's that whole werewolf thing. Why would this be? The reasoning is that the Moon, which affects the ocean's tides, probably exerts a similar effect on us, because the human body is made mostly of water.

This belief that the Moon influences behavior is so widely held—reportedly, even 80 percent of nurses and 64 percent of doctors think it's true, according to a 1987 paper published in the Journal of Emergency Medicine [PDF]—that in 2012 a team of researchers at Université Laval's School of Psychology in Canada decided to find out if mental illness and the phases of the Moon are linked [PDF].

To test the theory, the researchers evaluated 771 patients who visited emergency rooms at two hospitals in Montreal between March 2005 and April 2008. The patients chosen complained of chest pains, which doctors could not determine a medical cause for the pains. Many of the patients suffered from panic attacks, anxiety and mood disorders, or suicidal thoughts.

When the researchers compared the time of the visits to the phases of the Moon, they found that there was no link between the incidence of psychological problems and the four lunar phases, with one exception—in the last lunar quarter, anxiety disorders were 32 percent less frequent. "This may be coincidental or due to factors we did not take into account," Dr. Geneviève Belleville, who directed the team of researchers, said. "But one thing is certain: we observed no full-moon or new-moon effect on psychological problems."

So rest easy (or maybe not): If people seem to act crazy during the full Moon, their behavior is likely pretty similar during the rest of the lunar cycle as well.

While some travelers are preoccupied with getting their luggage through airport security, the designers at Arlo Skye are thinking bigger. As Condé Nast Traveler reports, the brand's new line of suitcases is inspired by space travel, with high tech features and a sleek, futuristic look.

Arlo Skye was founded in 2016 by alumni from Louis Vuitton and Tumi Inc. They set out to create luggage that emphasized design, with luxury polycarbonate suitcases available in trendy colors like rose gold and custom monogramming.

The company's Space Collection may be its most stylized line yet. It comes with a removable, 10,050-milliamp-hour charger with USB C and A ports for charging phones and other devices. The chrome-colored case is 22 inches tall, 9 inches deep, and 14 inches wide and weighs 8.5 pounds empty.

Depending on what type of space traveler you are, you can get one of three designs laser-etched on the bottom of your luggage. There's Moon Shot, Team Human, and Occupy Mars; each engraving comes with a short ode to space and a small picture of its respective celestial body. Like other suitcases made by Arlo Skye, these bags are zipper-free and made from polycarbonate with an aluminum frame.

Whether you're a globetrotter or an aspiring astronaut, the Space Collection from Arlo Skye makes a great travel companion.

Buy it from Arlo Skye for $450.
