NASA Launches Effort to Explore the Frozen Terrain of Jupiter’s Satellite Europa

## NASA’s Europa Clipper Mission: Unraveling the Secrets of Jupiter’s Icy Satellite

On Monday, NASA’s Europa Clipper spacecraft commenced a significant expedition, launching from Kennedy Space Center in Florida with a SpaceX Falcon Heavy rocket. This ambitious $5.2 billion venture seeks to investigate one of the most captivating spots in our Solar System—Europa, one of Jupiter’s moons, which may hold the potential for extraterrestrial life.

### Mission Launch and Overview

The Falcon Heavy rocket, powered by 27 kerosene engines, lifted off at 12:06 pm EDT (16:06 UTC) on Monday. The launch experienced delays of several days due to Hurricane Milton, but the spacecraft is en route to Jupiter, initiating a five-and-a-half-year voyage. Europa Clipper will orbit Jupiter and perform 49 close flybys of Europa, a moon enveloped in ice believed to contain a global ocean beneath its frigid exterior.

Europa has intrigued scientists for some time due to compelling evidence indicating the existence of a subsurface ocean. The main goal of this mission is to ascertain whether Europa possesses the necessary conditions to nurture life, particularly simple, single-celled organisms. “This is an extraordinary mission,” remarked Curt Niebur, Europa Clipper’s program scientist at NASA Headquarters. “It’s an opportunity for us to explore not just a world that might have been habitable eons ago, but one that could be habitable right now.”

### The Journey to Europa

NASA has had Europa in its sights since the Voyager probes captured images of Jupiter’s moons in 1979. In the following years, the Galileo mission, which orbited Jupiter from 1995 to 2003, provided compelling evidence of a liquid ocean beneath Europa’s icy shell. Nonetheless, despite sustained scientific interest, political and financial obstacles led to delays in the approval of a focused Europa mission for many years.

It was not until 2015, following years of advocacy from former U.S. Representative John Culberson, that NASA officially endorsed the Europa Clipper mission. A space science aficionado, Culberson was instrumental in securing the crucial funding for the endeavor.

### Rapid Launch and Technical Hurdles

Europa Clipper stands as NASA’s largest spacecraft to explore another celestial body, weighing in at over 12,500 pounds (5.7 metric tons) at liftoff. Its two enormous solar arrays, engineered to capture sunlight five times dimmer than that which reaches Earth, feature a wingspan of 100 feet (30.5 meters). Despite its size, the spacecraft required every bit of power from the Falcon Heavy rocket to break free from Earth’s gravity and commence its journey to Jupiter.

The spacecraft is set to cover 1.8 billion miles (2.9 billion kilometers) over the coming years, using gravitational assists from Mars in 2025 and Earth in 2026 to propel itself toward Jupiter. Europa Clipper is anticipated to reach Jupiter in April 2030, where it will kick off its mission to investigate Europa in unprecedented detail.

### The Science Behind Europa Clipper

Europa Clipper is outfitted with a collection of nine scientific instruments aimed at examining the moon’s icy veneer and the ocean beneath. This array includes high-resolution cameras, ice-penetrating radar, and a mass spectrometer to evaluate the composition of Europa’s surface and atmosphere.

One of the most thrilling prospects of the mission is the potential for detecting water plumes emanating from Europa’s surface. The Hubble Space Telescope has previously detected signs of such plumes, and if Europa Clipper flies through one, it could yield a direct sample from the moon’s subsurface ocean. This would present a phenomenal scientific opportunity, enabling researchers to examine the water for signs of life or its chemical precursors.

“Europa Clipper boasts the most advanced suite of instruments we’ve ever sent beyond the inner solar system,” stated Bob Pappalardo, the project’s scientist at NASA’s Jet Propulsion Laboratory (JPL). “We’ll be able to search for warm spots, plumes, and other indicators that might signify the presence of liquid water and organic materials.”

### The Quest for Life

The central aim of the mission is to evaluate whether Europa could sustain life. Scientists are convinced that Europa’s ocean, which could reach depths of 60 to 80 miles, might be warmed by hydrothermal vents located on the moon’s rocky ocean floor. These vents, akin to those on Earth’s seabed, may provide the necessary energy to uphold life in the absence of sunlight.

“We don’t anticipate discovering fish or whales,” Pappalardo noted. “But we’re keen to understand if Europa can support simple life—single-celled organisms.” While Europa Clipper won’t directly search for life, it will look for the chemical building blocks of life, including organic molecules and possible energy sources.

Apple Researchers Indicate that LLMs Do Not Possess Genuine Logical Reasoning Abilities

# The Vulnerability of AI Reasoning: How Misleading Cues Result in Major Failures in Logical Deduction

In recent times, organizations such as OpenAI and Google have been showcasing the sophisticated reasoning abilities of their artificial intelligence (AI) models as the forefront of machine learning advancements. Nonetheless, a recent investigation conducted by six engineers from Apple indicates that the reasoning capacities of these large language models (LLMs) might be more fragile than initially perceived. The study underscores how seemingly minor modifications to mathematical problems can result in major failures in logical deduction, prompting concerns regarding the dependability of AI in intricate reasoning scenarios.

## The Challenge of Pattern Recognition

The research, titled “GSM-Symbolic: Understanding the Limitations of Mathematical Reasoning in Large Language Models,” examines how LLMs tackle mathematical reasoning challenges. The scientists utilized the GSM8K dataset, a standardized collection of over 8,000 grade-school-level mathematical word problems, as their reference point. This dataset is frequently employed to assess the reasoning skills of contemporary LLMs.

However, the Apple team adopted an innovative strategy by altering the dataset to establish a fresh evaluation set dubbed GSM-Symbolic. In this revised set, they dynamically swapped particular names and numbers in the problems with new values. For instance, a query regarding Sophie purchasing 31 building blocks for her nephew could be transformed into Bill buying 19 blocks for his brother. These alterations did not modify the fundamental mathematical challenge posed by the problems, indicating that the models should, in theory, perform equivalently on GSM-Symbolic as they did on the original GSM8K.

The findings, however, were astonishing. Across over 20 cutting-edge LLMs, accuracy declined by an average of 0.3% to 9.2%, dependent on the model. Even more alarming was the considerable variance in performance across different instances of the same model, with accuracy swinging by as much as 15% between the best and worst performances. This implies that the models were not engaging in formal reasoning but were instead depending on probabilistic pattern recognition based on their training datasets.

## The Consequences of Misleading Cues

The vulnerability of AI reasoning became increasingly evident when the researchers incorporated irrelevant yet seemingly pertinent information into the problems. In a new benchmark set named GSM-NoOp (which stands for “no operation”), the researchers included trivial details in the questions. For instance, a question about how many kiwis a person picked might mention that “five of them were smaller than average.”

These misleading cues resulted in what the researchers referred to as “catastrophic performance drops” in accuracy, varying from 17.5% to a striking 65.7%, depending on the model. The models frequently misconstrued the irrelevant details as essential to solving the issue, resulting in incorrect conclusions. For example, in the kiwi scenario, many models attempted to subtract the smaller fruits from the total, even though this was unnecessary for the problem.

This type of error underscores a significant defect in how LLMs approach reasoning tasks. Rather than genuinely comprehending the problem, the models seem to rely on pattern recognition from their training data, transforming statements into actions without fully understanding their significance.

## The Mirage of Comprehension

The insights from this study are not entirely novel. Prior research has also indicated that LLMs do not engage in formal reasoning but instead simulate it through probabilistic pattern recognition. However, the work conducted by the Apple researchers highlights just how vulnerable this simulation can be when the models encounter unexpected or irrelevant information.

This vulnerability points to a wider challenge in AI development: the “mirage of comprehension.” As AI models increase in size and complexity, they can create the illusion of true understanding by amalgamating extensive amounts of training data in unique manners. Nevertheless, this is not synonymous with authentic reasoning or comprehension. As AI specialist Gary Marcus has contended, the next considerable advancement in AI capability will occur when neural networks can execute true “symbol manipulation,” wherein knowledge is represented abstractly in terms of variables and operations, similarly to algebra or traditional computer programming.

Until that advancement is realized, AI models will persist in having difficulties with tasks that demand genuine reasoning, particularly when confronted with misleading cues or other irrelevant data. This limitation is especially troubling in domains like mathematics, where even minor misjudgments in reasoning can lead to substantial repercussions.

## Conclusion

The research from Apple engineers acts as a poignant reminder that while AI has achieved remarkable progress in recent years, it still faces considerable limitations regarding reasoning and deduction. The vulnerability of LLMs when encountering irrelevant information emphasizes the necessity for more resilient models that can participate in authentic logical reasoning, rather than merely relying on pattern recognition from their training datasets.

As AI continues to advance, it is critical for researchers and developers to tackle these shortcomings. Without a deeper grasp of the fundamental concepts underlying reasoning tasks, AI models will remain susceptible to failures, especially in intricate or unforeseen circumstances. The next

Ward Christensen, Innovator of the Bulletin Board System (BBS) and Creator of Early Online Communication, Dies at 78

**Ward Christensen: The Modest Innovator Who Launched Online Culture**

On Friday, Ward Christensen, co-creator of the computer bulletin board system (BBS), passed away at the age of 78 in Rolling Meadows, Illinois. Together with Randy Suess, he developed the first BBS in 1978, a groundbreaking innovation that provided the groundwork for the digital communities that would eventually transition into the contemporary internet. His efforts ignited a cultural transformation, motivating countless hobbyist groups and establishing the framework for the online landscape we are familiar with today.

### A Unassuming Trailblazer

Despite his significant impact on technology, Christensen remained modest throughout his lifetime. He never pursued the limelight, concentrating instead on his extensive career at IBM, where he worked from 1968 until his retirement in 2012. Friends and acquaintances remember him as a gentle and unobtrusive presence, pleased with his accomplishments but never self-important.

Jason Scott, the creator of *BBS: The Documentary*, which thoroughly explored Christensen’s contributions, referred to him as “the quietest, most pleasant, gentlest guy.” Scott, who interviewed Christensen in 2002, observed that despite his crucial part in shaping the digital era, Christensen was more akin to “a groundskeeper who quietly maintains the yard” than a tech entrepreneur chasing notoriety.

The announcement of Christensen’s passing was initially made by tech veteran Lauren Weinstein on social media, and a close friend confirmed that he died peacefully at his residence. The specifics of his cause of death have not been released to the public.

### The Genesis of BBS and XMODEM

Prior to inventing the first BBS, Christensen created XMODEM in 1977, a file transfer protocol that became essential for the BBS network. XMODEM facilitated the division of files into packets for transmission over analog phone lines, ensuring dependable delivery even amid noisy and unstable connections. This groundbreaking work enabled users to share files and communicate long before the internet became prevalent.

The concept for the first BBS emerged during the *Great Blizzard of 1978*, when Christensen and Suess, members of the Chicago Area Computer Hobbyists’ Exchange (CACHE), were unable to attend their regular computer club meetings because of the snowstorm. They sought a method to keep in touch with fellow members despite physical limitations. Suess developed the hardware while Christensen programmed the software, which they named *CBBS* (Computerized Bulletin Board System).

In just two weeks, the duo completed the first BBS, although they humorously told others it took four weeks to avoid the perception of haste. The system became operational on February 16, 1978, allowing users with modems to dial in, leave messages, and converse with others. It served as a digital counterpart to the physical bulletin boards typically found in grocery stores and community centers.

### The Expansion of BBS Culture

Christensen and Suess did not keep their invention to themselves. They freely disseminated the idea of the BBS, prompting others to develop their own versions of BBS software. As these systems advanced in complexity, they enabled users not just to leave messages but also to transfer files and engage in gaming. BBSes emerged as a central hub for early online communities, introducing many home computer users to the world of multiplayer gaming, message boards, and digital socialization.

The BBS movement also fostered the shareware gaming phenomenon, which would eventually lead to the establishment of companies like Epic Games, the creators of *Fortnite*. In numerous ways, BBSes served as the antecedent to the modern internet, creating a platform for community-building and content sharing well before the World Wide Web became mainstream.

### A Timeless Impact

Randy Suess passed away in 2019, and with Christensen’s death, the era of the original BBS pioneers has concluded. Nevertheless, their impact endures. While most BBSes have transitioned to internet-based platforms, a few still exist today, often accessed through the internet rather than dial-up connections.

Christensen’s contributions were recognized during his lifetime. In 1992, he received two Dvorak Awards, including a lifetime achievement accolade for his work in PC telecommunications. The following year, the Electronic Frontier Foundation presented him with the Pioneer Award, acknowledging his influence in shaping the digital domain.

Despite these honors, Christensen remained unpretentious. In his later years, he continued to participate in online communities, often without spotlighting his role in devising the technology that enabled much of it. Jason Scott, who closely tracked Christensen’s contributions, was continually struck by his humility. “It would be like a person who was in a high school band saying, ‘Eh, never really got into touring, never really had the urge to record albums or become a rock star,'” Scott remarked. “And then later people come and go, ‘Oh, you made the first
