Humanoid robots, space travel, the science of aging--Musk was willing to weigh in on all of it at this week's World Economic Forum. But his predictions rarely work out the way he says they will. Elon Musk speaks during the World Economic Forum Annual Meeting in Davos, Switzerland on Thursday. Elon Musk, the richest man on Earth, is very good at making money. His track record of predicting the future is less stellar.

Comprehensive forecasts of space tourism demand are crucial for businesses to optimize strategies and customer experiences in this burgeoning industry. Traditional methods struggle to capture the complex factors influencing an individual's decision to travel to space. In this paper, we propose an explainable and trustworthy artificial intelligence framework to address the challenge of predicting space tourism demand by following the National Institute of Standards and Technology guidelines. We develop a novel machine learning network, called SpaceNet, capable of learning wide-range dependencies in data and allowing us to analyze the relationships between various factors such as age, income, and risk tolerance. We investigate space travel demand in the US, categorizing it into four types: no travel, moon travel, suborbital, and orbital travel. To this end, we collected 1860 data points in many states and cities with different ages and then conducted our experiment with the data. From our experiments, the SpaceNet achieves an average ROC-AUC of 0.82 $\pm$ 0.088, indicating strong classification performance. Our investigation demonstrated that travel price, age, annual income, gender, and fatality probability are important features in deciding whether a person wants to travel or not. Beyond demand forecasting, we use explainable AI to provide interpretation for the travel-type decisions of an individual, offering insights into the factors driving interest in space travel, which is not possible with traditional classification methods. This knowledge enables businesses to tailor marketing strategies and optimize service offerings in this rapidly evolving market. To the best of our knowledge, this is the first work to implement an explainable and interpretable AI framework for investigating the factors influencing space tourism.

Astronauts aboard the International Space Station (ISS) had slower memory, attention and processing speed after six months, raising concerns about the impact of cognitive impairment on future space missions to Mars. The extreme environment of space, with reduced gravity, harsh radiation and the lack of regular sunrises and sunsets, can have dramatic effects on astronaut health, from muscle loss to an increased risk of heart disease. However, the cognitive effects of long-term space travel are less well documented. Inside NASA's ambitious plan to bring the ISS crashing back to Earth Now, Sheena Dev at NASA's Johnson Space Center in Houston, Texas, and her colleagues have looked at the cognitive performance of 25 astronauts during their time on the ISS. The team ran the astronauts through 10 tests, some of which were done on Earth, once before and twice after the mission, while others were done on the ISS, both early and later in the mission.

Long-distance space travel can wreak havoc on human health. There's radiation and microgravity to contend with, as well as the psychological toll of isolation and confinement. Research on identical twin astronauts has also revealed a slew of genetic changes that happen when a person spends a year in space. That's why some bioethicists are exploring the idea of radical treatments for future astronauts. Once we've figured out all the health impacts of space travel, they argue, we should edit the genomes of astronauts ahead of launch to offer them the best protection.

A renowned astrophysicist is calling foul on reports of alien sightings in Earth's atmosphere, arguing that biological creatures would be unable to survive a journey to our planet. "It would take about a billion years to cross from one side of the Milky Way galaxy to the other," Avi Loeb, a Harvard astrophysicist, said during an appearance on GB News this week. "Given that, I don't think any spacecraft that would arrive to us from another star would carry biological creatures." Loeb's comments come amid increased reports of UFO sightings in recent years, with videos and pictures of supposed alien craft going viral across the internet. It also comes after NASA created a new position aimed at overseeing research on UFOs after a 2022 study by the agency determined that such sightings were unlikely to be caused by extraterrestrial life.

The Apollo 11 moon landing was a seminal event in American history, one etched deeply into our nation's collective psyche. The event ushered in an era of unbridled possibilities -- the stars were finally coming into reach -- and its effects were felt across the culture, from art and fashion to politics and culture. In After Apollo: Cultural Legacies of the Race to the Moon, a multidisciplinary collection of historians, researchers and academics explore the myriad ways that putting a man on the moon impacted the American Experience.

From NASA's very beginnings, immigrant engineers, scientists, and technicians lent their talent, labor, and technical skills to the space program.

After a four-year hiatus, Black Mirror is back. Season six is now on Netflix, along with the whole back catalog--including one Christmas special and an interactive movie. The show, created by Charlie Brooker and producer Annabel Jones, is a modern take on classic anthology series like The Twilight Zone. Through Brooker's dark, playful, and sometimes uplifting lens, the show examines the unintended ways technology impacts our lives. Because it's an anthology series--in which each installment has new subject matter and a slightly different tone--each episode has its fans.

When Dr Uri Shumlack was contacted by a video game developer who wanted to discuss his work on interstellar propulsion, for a game about spaceflight, he was wary. A professor of aeronautics and astronautics at the University of Washington, he was a busy individual, and not exactly an avid gamer. He asked some of his engineering undergraduates whether they had heard of a game called Kerbal Space Program, only to discover that half the class were there because of the game. First playable in 2011, Kerbal Space Program is an idiosyncratic and extremely difficult video game that involves getting little green aliens off the surface of their planet using rockets that you must cobble together from a library of parts. To do this, though – and leave the launchpad without exploding – you have to develop a pretty good understanding of the physics of space travel, calculating orbit trajectories and figuring out how much fuel you need, and whether you can carry it without messing up your thrust-to-weight ratio.

Disabled astronauts-in-training have completed a zero-gravity flight 25,000ft above Earth to help understand how spacesuits and space vessels can be made more accessible. The crew of 14, who have mobility, vision and hearing difficulties, experienced weightlessness and carried out a number of tests to see what could be done to improve accessibility. The group, who were from five different countries, including Australia, Brazil, Germany, Spain and the US, was made up of scientists, engineers and doctors. The groundbreaking trip, organised by AstroAccess, happened on a Zero-G aircraft in Houston, Texas on Thursday. Disabled astronauts-in-training have completed a zero-gravity flight 25,000ft above Earth to help understand how spacesuits and space vessels can be made more accessible.

As artificial intelligence travels through the solar system and gets to explore the heliosphere (enclosing the planets), it will adapt by making decisions that enable it to do its job. Many people in the field of astrobiology are in favour of the so-called post-biological cosmos vision. Is it because of the desire to conquer space that we humans are sowing the seeds of our own destruction in favour of artificial intelligence? Or are we unconsciously following some sort of master plan in which flesh and blood beings are destined to become extinct and be hybridised by silicon and synthetic materials? As for the mind, memory, consciousness, could there also be a place for humans in a robot's brain?
