DANTE LAURETTA SAT IN THE BACKSEAT OF A HELICOPTER HOVERING HIGH ABOVE A REMOTE PATCH OF UTAH DESERT, WAITING FOR A SMALL, TWINKLING SPECK IN THE SKY TO PLUNGE TOWARD EARTH.
If you didn't know better, you might think what was beginning to burn through the skies above the American southwest in the early hours of September 24, 2023, was a shooting star. But it wasn't a shooting star. Or a meteor. It was a dishwasher-size capsule filled with bits of ancient asteroid-priceless matter from the dawn of the solar system. In other words, it was a treasure chest moving at 27,000 miles per hour and sizzling at a temperature half that of the sun's surface.
That small streak of light represented the end of a NASA-led interplanetary mission suffused with peril. Lauretta and his colleagues had spent nearly 20 years building a spacecraft designed to collect material from an asteroid and return to Earth. From these precious grains, they hoped to gain insight about the formation of the solar system, of Earth, and maybe even of life itself.
What the capsule had to do now, completely autonomously, was simple: stay in one piece as it reentered the atmosphere, open its parachutes, and softly touch down on an Air Force bombing range without detonating any unexploded ordnance nearby.
By 8:44 a.m., the capsule was 102,300 feet above the ground, and its drogue parachute-the canopy meant to stabilize its plunge-should have opened by now. But no one could see it.
Throngs of scientists and engineers who had worked on the spacecraft, spread out across mission control rooms in Arizona and Colorado, were now deathly quiet.
It looked like something had gone wrong. And all Lauretta, the mission's leader, could do was watch, and hope, that his life's obsession wasn't about to be scattered across the desert. He wasn't even supposed to oversee the mission.

The Ancient Language of Easter Island - Today, humans inhabit- or have, at the very least, explored- pretty much every corner of the planet. But that immense proliferation of Homo sapiens across the globe was a slow process.
With the first humans leaving Africa between 60,000 and 120,000 years ago, the species slowly spread across the Earth over many millennia. And one of the last places these ancient humans made their way to was the southeastern Pacific island of Rapa Nui, known more broadly as Easter Island.Located 2,360 miles off the coast of Chile, Rapa Nui is one of the most isolated places in the world. Its native people, who are also named the Rapa Nui, first arrived on the island's shores between A.D. 1150 and 1280, and lived in isolation until the arrival of Dutch navigator Jacob Roggeveen in 1722.
Underwater UFOs - A retired U.S. Navy admiral believes that the government should look to the oceans to help solve a mystery in the skies.
A retired U.S. Navy admiral believes that the government should look to the oceans to help solve a mystery in the skies. Rear Admiral Timothy Gallaudet, former Oceanographer of the U.S. Navy, recently published a paper arguing that unidentified anomalous phenomena (UAP, more commonly referred to as UFO) and unidentified submersible objects (USO) are linked, and should be studied further.
Synching Up Our Circadian Rhythms - If you've ever done any kind of long-distance travel, or just woken up feeling under-rested thanks to daylight saving time, you know how important your circadian clock is.
If you've ever done any kind of long-distance travel, or just woken up feeling under-rested thanks to daylight saving time, you know how important your circadian clock is. Like many things in your body, your circadian rhythm is more complicated than it might seem on the surface. Rather than being entirely brain-based, it's actually controlled by a collection of several circadian clocks (central and peripheral) that all work together to keep your gears turning like a well-oiled machine.
