Thousands of Tardigrades Are Stranded on the Moon After an Israeli Lunar Lander Crashed

Tardigrades, known to many as water bears or moss piglets, may be the cutest organisms you need a microscope to see. They're also remarkably tough: The miniscule creatures are capable of producing glass shields in their cells to protect themselves in extreme conditions, and they can survive almost anywhere, including space. Now, as BBC News reports, their resilience is being put to the test. Last April, an Israeli spacecraft crashed and dumped thousands of tardigrades on the Moon, and mission officials say their chance of survival is "extremely high."

The spacecraft that crash-landed on the moon last spring had been carrying a "backup of planet Earth." The mission was organized by the Arch Mission Foundation, a nonprofit that aims to amass libraries of human knowledge and history and store them in various spots around the solar system for safekeeping. This particular collection contained human DNA samples, a CD-ROM-like disc inscribed with 30 million pages of information, and dehydrated tardigrades.

The lunar library hitched a ride aboard Israel Aerospace Industries' Beresheet spacecraft in what was to be the first-ever private Moon landing. The endeavor failed at the last minute when the lander's main engine malfunctioned as it approached the Moon's surface, resulting in a collision. The Beresheet spacecraft may not have survived the journey, but according to Arch Mission Foundation CEO Nova Spivack, its thousands of tardigrades passengers likely did.

When tardigrades are dehydrated, they're virtually indestructible. In the face of danger, they enter this near-death state on their own and manage without food, water, or even air until conditions improve. They can live this way for decades without an issue, and when they're rehydrated, they instantly resume life as normal.

Spivack's prediction that the tardigrades are doing fine on the Moon is more than just a hunch: The creatures have been brought to space before and survived. This case, however, isn't a controlled experiment, and introducing a new species to the surface of the Moon could have unforeseen consequences. Humans have left objects on the Moon before—like golf balls, art, and even feces—but never such complex living organisms.

If the lunar library remained intact through the crash, it may be possible for future missions to retrieve it and conduct tests on the tardigrades once they are brought back to Earth. Until then, there's a strong likelihood that Earth is no longer the only celestial body in our solar system that's supporting life.

Did the Northern Lights Play a Role in the Sinking of the Titanic? A New Paper Says It’s Possible

The sinking of the RMS Titanic on April 15, 1912, is the most famous maritime disaster in history. The story has been retold countless times, but experts are still uncovering new details about what happened that night more than a century later. The latest development in our understanding of the event has to do with the northern lights. As Smithsonian reports, the same solar storm that produced an aurora over the North Atlantic waters where the Titanic sank may have caused equipment malfunctions that led to its demise.

Independent Titanic researcher Mila Zinkova outlines the new theory in a study published in the journal Weather. Survivors and eyewitnesses from the night of the Titanic's sinking reported seeing the aurora borealis light up the dark sky. James Bisset, second officer of the ship that responded to the Titanic's distress calls, the RMS Carpathia, wrote in his log: "There was no moon, but the aurora borealis glimmered like moonbeams shooting up from the northern horizon."

Zinkova argues that while the lights themselves didn't lead the Titanic on a crash course with the iceberg, a solar storm that night might have. The northern lights are the product of solar particles colliding and reacting with gas molecules in Earth's atmosphere. A vivid aurora is the result of a solar storm expelling energy from the sun's surface. In addition to causing colorful lights to appear in the sky, solar storms can also interfere with magnetic equipment on Earth.

Compasses are susceptible to electromagnetic pulses from the sun. Zinkova writes that the storm would have only had to shift the ship's compass by 0.5 degrees to guide it off a safe course and toward the iceberg. Radio signals that night may have also been affected by solar activity. The ship La Provence never received the Titanic's distress call, despite its proximity. The nearby SS Mount Temple picked it up, but their response to the Titanic went unheard. Amateur radio enthusiasts were initially blamed for jamming the airwaves used by professional ships that night, but the study posits that electromagnetic waves may have played a larger role in the interference.

If a solar storm did hinder the ship's equipment that night, it was only one condition that led to the Titanic's sinking. A cocktail of factors—including the state of the sea, the design of the ship, and the warnings that were ignored—ultimately sealed the vessel's fate.
