Emergency SOS via Satellite Saves Students Trapped in Utah Canyon
The students who were involved spoke to Utah’s KUTV (via AppleInsider) and described their dangerous ordeal. One of the students, Bridger Woods, said that the three had heard about a “pretty cool canyon” that they decided to check out because they had been canyoneering for approximately a year.
Inside the canyon, they encountered an area that had unexpectedly deep water, potentially caused by a wet winter in Utah. Woods and another student, Jeremy Mumford, were stuck in the pool for over an hour, but they ultimately were able to get out and continue deeper. They encountered another pool where the water was chest deep, and they could not get out.
Two of the students were experiencing symptoms of hypothermia, and because of the location of the canyon, there was no cellular signal, but the third student, Stephen Watts, had an iPhone 14. According to Mumford, every 20 minutes, a “satellite would line up” to their location, and holding the phone up, they were able to get enough satellite signal to text 911.
While waiting for emergency services, the trio were able to leverage themselves out of the deep pool using rope and carabiners. With Woods going into hypothermic shock, they were still unable to get out of the 10 to 15 foot hole that they were in. Instead, they located driftwood and began a fire to warm up while emergency crews came to their rescue.
A helicopter crew from Salt Lake City arrived, as did paramedics from Arizona, and all three students were ultimately unharmed. The group told KUTV that they recommend taking a satellite phone on adventures in case of an emergency situation.
Emergency SOS via Satellite has already been used in several other life-threatening situations, including when an Alaskan man was stranded in the wilderness and when people were involved in a serious crash in the Angeles National Forest in California.
Emergency Satellite via SOS is available to all iPhone 14 users in select countries, and it can be activated when an emergency situation occurs and there is no WiFi or cellular connection available. The feature is free to use for two years, and Apple has not yet provided detail on how much it will cost going forward.

Water trapped in tiny glass beads on the Moon could hydrate future settlements
China’s Chang’e 5 rover has found tiny glass beads containing water in an impact crater on the Moon. Samples collected from a 2020 mission found beads with water content as high as 2,000 parts per million (PPM). Given the prevalence of these glass spheres on the lunar surface, there may be enough to provide 71 trillion gallons of water.
Some beads formed when asteroids collided with the Moon millions of years ago, while others came from ancient volcanoes. Scientists believe the water originated from a chemical reaction when hydrogen ions emitted from the sun — transported to the lunar surface from solar winds — combined with oxygen atoms inside the beads. The water-filled beads are tiny, ranging from “tens of micrometers to a few millimeters.” Still, there are enough on the Moon’s surface to (theoretically) supply an estimated 270 trillion kilograms of water — enough to fill 100 million Olympic-sized swimming pools.
However, scientists haven’t yet figured out how to collect them, and they would need to heat them to around 212 degrees Fahrenheit to extract water. Still, they could be a resource for future lunar settlements, where astronauts could use water for drinking, bathing, cooking, cleaning and even producing rocket fuel.
Scientists believe other moons in our Solar System may have similar beads. “Our direct measurements of this surface reservoir of lunar water show that impact glass beads can store substantial quantities of solar wind-derived water on the moon and suggest that impact glass may be water reservoirs on other airless bodies,” the study’s authors wrote. “The presence of water, stored in impact glass beads, is consistent with the remote detection of water at lower-latitude regions of the Moon, Vesta and Mercury. Our findings indicate that the impact glasses on the surface of Solar System airless bodies are capable of storing solar wind-derived water and releasing it to space.”
The glass beads aren’t our first glimpse at water on the Moon. In 2009, NASA crashed a probe into the Cabeus crater that led to water detection; in 2018, NASA found direct evidence of ice deposits in the Moon’s permanently shadowed craters on its north and south poles. NASA and China / Russia plan to put lunar bases at the Moon’s South Pole within the next decade; the competing initiatives both hope to have inhabitable bases ready by the early-to-mid-2030s.
