NASA’s Artemis program continues to advance our understanding of the Moon with the selection of a new scientific payload called DIMPLE (Dating an Irregular Mare Patch with a Lunar Explorer). This instrument suite will focus on studying the hilly terrain formed by volcanic activity on the near side of the Moon, specifically the Ina Irregular Mare Patch. By investigating this mound, scientists hope to uncover valuable insights into the Moon’s evolution and gain clues about the history of our solar system.

DIMPLE is the outcome of the PRISM (Payloads and Research Investigations on the Surface of the Moon) proposal call, an initiative facilitated by NASA’s Commercial Lunar Payload Services (CLPS). This marks the first PRISM call that allows researchers to choose and justify a specific landing site for conducting high-priority lunar science investigations. The cost for the DIMPLE payload suite is capped at $50 million, and it is expected to be delivered no earlier than the second quarter of 2027. NASA plans to issue a CLPS task order in 2024 to determine the launch services for DIMPLE’s journey to the Moon.

This endeavor is part of NASA’s broader lunar plans under the Artemis program, which aims to explore the Moon extensively using advanced robotics and astronauts. Through DIMPLE, scientists hope to determine whether Irregular Mare Patches were formed by recent or ancient volcanic processes. The mission will utilize a CLPS-provided rover, a collection gripping instrument, and a spectrometer to analyze the age and composition of samples collected from Ina’s surface. DIMPLE is capable of gathering and analyzing anywhere from three to more than 25 samples, offering valuable insights into the timing of the volcanic activity that shaped this feature.

The findings from DIMPLE could have significant implications for our understanding of the Moon’s geochemical state over time. If the volcanic activity is found to be geologically recent, it could suggest that the lunar mantle was warmer than previously believed or that radioactive elements contributed to ongoing small-scale eruptions. On the other hand, if the eruptions are determined to be older, it would prompt a reassessment of the age and evolution of craters on the Moon, providing crucial insights into the history of Earth and other planets in our solar system.

Joel Kearns, the deputy associate administrator for exploration in NASA’s Science Mission Directorate, emphasizes that DIMPLE’s selection aims to definitively resolve the debate surrounding the Moon’s recent volcanic activity. This mission not only poses intriguing scientific questions but also demonstrates an exciting technology that can be employed to measure absolute ages of diverse geologic terrains across the solar system.

The principal investigator for the DIMPLE mission is F. Scott Anderson from the Southwest Research Institute’s Solar System Science and Exploration Division in Boulder, Colorado. The CLPS initiative, which leverages commercial launch providers, plays a crucial role in NASA’s Artemis lunar exploration efforts, enabling cost-effective scientific advancements on the Moon’s surface. These science and technology payloads will pave the way for future human missions.

airships

In the late 19th century, America was buzzing with the thrill of innovation and exploration. However, amidst the technological advancements, an inexplicable phenomenon began to capture the imagination of many: mysterious airships sighted across the sky. This captivating mystery still puzzles historians and enthusiasts today, raising questions about whether they were mere figments of imagination, hoaxes, or something far more otherworldly.

The Birth of the Mystery

The saga of the mystery airships began in 1896 when reports of strange airships started to emerge from various locations in the United States. From California to Texas, witnesses described seeing cigar-shaped vessels flying through the night sky, illuminated by bright lights. Initial sightings created a flurry of excitement and speculation—newspapers quickly picked up the stories, printing illustrations and accounts that fueled the imaginations of readers.

Witness Accounts: Fact or Fiction?

Witnesses reported diverse descriptions of these airships. Some claimed the vessels hovered silently, while others insisted they produced loud noises that resembled the sounds of machinery or engines. People recounted instances of the airships being seen low enough to see their intricate details, leading many to ponder their origin.

One of the most famous sightings occurred in November 1896 when a newspaper reported that the airship was spotted over Sacramento, California. The pilot was said to have communicated with stunned citizens below, declaring his craft had been developed by a local inventor. Reports flooded in from other areas, each new sighting adding layers to the growing enigma.

Theories and Speculation

As excitement grew, so did the range of theories about the identity of the airships. Some suggested they were the result of secretive military testing, while others posited that they were experimental aircraft developed by inventors hoping to capitalize on the burgeoning aerospace industry. Conspiracy theories soon emerged, suggesting the airships were extraterrestrial craft, aliens visiting Earth long before modern UFO sightings became popular.

Another prevalent theory was that the airships were elaborate hoaxes created by pranksters or con artists. The media of the time jumped at the chance to sensationalize these stories, leading to speculation and possibly embellished accounts. Whether the sightings had factual bases in truth or were mere products of an imaginative society was a question many grappled with.

The Decline of the Phenomenon

By the turn of the century, reports of the mysterious airships began to wane. As the 20th century ushered in advancements in aviation technology, the public’s focus shifted toward real developments in flight, including the Wright brothers’ first powered flight in 1903. Interest in the mystery airships diminished, becoming a curious footnote in UFO and aviation history.

Legacy and Cultural Impact

Even today, the legacy of the mystery airships endures in popular culture. They have been the subjects of countless books, documentaries, and podcasts exploring the thin line between reality and imagination. The 1896 sightings continue to be cited in discussions about early UFOs, serving as a fascinating precursor to the modern fascination with unidentified flying objects.

As we unravel this historical enigma, we are reminded of humanity’s insatiable curiosity about the skies above. Whether rooted in fact or fictional fantasy, the mystery of the 1896 airships still invites exploration into the unexplained and provokes questions that resonate through time.

“Dolphins: The Ocean’s Overachievers”

Published

on

Dolphins
Dolphins are Smartypants

Ah, dolphins. The ocean’s golden retrievers. If the sea had a valedictorian, it would be a dolphin—wearing a tiny graduation cap, flipping its tail, and probably showing off by solving a Rubik’s Cube underwater. These marine marvels are the ultimate overachievers of the aquatic world, and frankly, they make the rest of us look bad.

“Dolphins: The Ocean’s Overachievers”

Dolphins

First off, dolphins are ridiculously smart. Scientists say they’re second only to humans in intelligence, which is both impressive and mildly insulting. I mean, have you ever seen a dolphin try to assemble IKEA furniture? No, because they’re too busy inventing underwater sonar and teaching each other how to use sponges as tools. Meanwhile, I’m over here struggling to open a bag of chips without ripping it in half.

And let’s talk about their social lives. Dolphins are the ultimate extroverts. They travel in pods, which is basically the ocean’s version of a group chat that never stops buzzing. They’re always playing, gossiping, and probably roasting each other about who’s the slowest swimmer. They even have names for each other! Can you imagine? “Hey, Flipper, pass the seaweed!” “Nice one, Bubbles, but I’m busy teaching this octopus how to high-five.”

But here’s the kicker: dolphins are also pranksters. They’ve been known to blow bubbles and then swim through them like it’s some kind of underwater TikTok trend. They’ll also play catch with pufferfish, not because they’re hungry, but because the pufferfish release toxins that give them a little “buzz.” That’s right—dolphins are out here getting high on pufferfish while the rest of us are debating whether pineapple belongs on pizza.

And don’t even get me started on their acrobatics. Dolphins can leap 20 feet out of the water, spin in midair, and land gracefully like they’re auditioning for Dancing with the Stars: Ocean Edition. Meanwhile, I trip over my own feet walking to the fridge.

So, what’s the takeaway here? Dolphins are smarter, cooler, and more fun than most of us will ever be. They’re the ocean’s MVP, and honestly, they know it. But hey, at least we have thumbs, right? …Oh wait, they’ve probably figured out how to use those too by now.

Stay salty, my friends. And if you see a dolphin, just bow. They deserve it. 🐬

Understanding paranormal beliefs and conspiracy theories isn’t just about misinformation – this course unpacks the history

Published

on

Uncommon Courses is an occasional series from The Conversation U.S. highlighting unconventional approaches to teaching.

Title of course:

“Investigating the Paranormal”

What prompted the idea for the course?

My training and professional work have been in Mesoamerican archaeology, but I’ve had a lifelong fascination with paranormal concepts. In fact, I considered studying the UFO community for my doctoral research in cultural anthropology.

I eventually fused these two interests in my book “Spooky Archaeology: Myth and the Science of the Past,” which examines why archaeology shows up so much in ideas about the mysterious and weird. Most people are familiar with pop culture characters like Indiana Jones seeking magical artifacts. Perhaps less immediately obvious is just how common archaeological topics are in paranormal and conspiracy culture.

The popularity of paranormal ideas – from television shows and thousands of podcasts to UFOs on the front page of The New York Times and in government investigations – made it clear that a course on paranormal culture would be an excellent way for students to get a taste of social science research.

What does the course explore?

The material begins with premodern ideas of magic, myth and metaphysics. The narrative that “Western” societies tell of the development of the modern world is that the Enlightenment cast off supernatural thinking in favor of science. The historical reality, however, is not so simple.

As science based on observation of material evidence emerged in the 17th through 19th centuries, so did a paranormal worldview: theories about a nonmaterial or hidden reality beyond the mundane, from monsters to psychic powers. Some of these ideas were tied to older religious notions of the sacred or strange but not divine phenomena. Others were new – particularly those suggesting the hidden existence of prehistoric extinct creatures or lost cities.

In either case, the key element was that proponents of these ideas often tried to support their existence with the kind of evidence used in science, though their “proofs” fell short of scientific standards. In other words, the paranormal is in conflict with the knowledge and worldview of modernity but also attempts to use the concepts of modernity to oppose it.

The class examines how this tension produced 20th century “-ologies” like parapsychology, which examines evidence for consciousness beyond matter, and cryptozoology, which searches the ends of the Earth for creatures tied to the mythic past. We also learn about UFOlogy, whose proponents have collected alleged contacts with technology and beings from beyond this world ever since the Cold War, as great earthly powers filled the skies with secretive hi-tech aircraft and spaceships.

As the class concludes, we examine how the “-ologies” declined after the Cold War, alongside the cultural capital of science, whose height of public respect was in the mid-20th century. Since then, proving the existence of paranormal things to institutional scientists has become less important in paranormal communities than promoting them to a broader public.

Why is this course relevant now?

Beyond public interest in paranormal topics, the paranormal is entwined with sociocultural forces that have dramatically increased the role of conspiracy rhetoric in the United States and elsewhere. At their core, both types of belief claim to have figured out some kind of supposedly hidden knowledge.

Furthermore, the conspiracy theories that are now commonplace in American political discourse are more rooted in paranormal ideas than in previous decades. Conspiracy theories about the JFK assassination or even 9/11 were still largely within the materialist realm. People argued that “the truth” had been covered up, but their arguments did not rely on metaphysical ideas. Today, major conspiracy theories involve secret cabals, mystical symbols and code words, demonic forces and extraterrestrial entities.

What’s a critical lesson from the course?

Evidence must be interrogated on its own, regardless of whether it fits your perspective. I find time and again that students have a hard time approaching evidence without bias, whether that bias is conscious or not: “knowing” that something must be true, or must be absurd.

One person apparently makes a death bed confession of faking a famous Loch Ness Monster photo, pleasing skeptics. Another claims to have seen a Bigfoot at close range, pleasing believers. Without further evidence, both are stories: no more, no less.

The issue isn’t to draw an equivalence between the bigger concepts. Not all narratives are equally well-founded. But students learn how to collect evidence, rather than simply rely on their gut sense of what is plausible or not.

What will the course prepare students to do?

This course is meant to help students discern useful and reliable information about claims and events, separating them from irrelevant or inaccurate narratives or sources. The goal is not just “critical thinking” aimed at combating disinformation, though that is part of what they should learn. Students practice evaluating evidence but also develop an approach for analyzing and understanding phenomena behind it: how factors like history, culture and institutions of authority, such as science and government, shape what people trust and what they believe.
