The Logistics of Going “Interplanetary”: What Does It Take to Live on the Moon?

Posted by in categories: economics, solar power, space, sustainability

Humans have been dreaming of living on the Moon, but what would that look like exactly?

Put simply, an outpost (or outposts) on the Moon could benefit humanity in numerous ways. It would allow for regular access to the lunar surface, enable vital research into low-gravity and its effects on terrestrial organisms, and shave billions off of the cost of missions destined for Mars and other locations in deep space.

Could F-35s Get New Engines by 2027? The US Congress Thinks So

Posted by in categories: energy, government, military

A flurry of upgrades is on the horizon.

The conference version of the National Defense Authorization Act of 2022 shows that the U.S. Congress wants new engines to be installed in the current and future F-35 aircraft starting from 2027, Air Force Magazine reported.

We had earlier reported that the U.S. military would be required to look into re-engining its F-35s towards the end of this decade. The F-16s and A-10C Thunderbolts are close to the end of their lifetimes which means that the bulk of the workload for the U.S. military will fall on F-35s’ shoulders. Under the Adaptive Engine Transition Program (AETP), the U.S. Air Force has already begun work to develop engines that can deliver more power or range as required.

Biggest Space Telescope In History Will Launch Just As 2021’s Smallest Full Moon Rises: What You Can See In The Night Sky This Week

Posted by in category: space

What To Watch For In The Night Sky This Week: December 13–19, 2021 An era-defining rocket launch happens this week. Much-delayed, over budget and high on science promises, the James Webb Space Telescope (JWST) will—finger’s crossed—finally go skywards this week… though it might be wise to expect delays. Also this week is the year’s most prolific meteor shower and a final full Moon for fall—the “Cold Moon.”

Here’s everything you need to know about stargazing, moon-watching and rocket launches this week:

Isotope analyses unlock Iron Age secrets

Posted by in category: futurism

Elemental and lead isotope analyses of ancient copper ingots are unlocking secrets of Early Iron Age trade routes and how indigenous Mediterranean communities functioned from about 2,600 years ago.

For the first time, a scientific team led by Flinders University archaeologists, working with the Institute of History (CSIC) in Spain, has examined the origins of Iron Age metal items from an in southwest France and found they were sourced from a variety of Mediterranean locations.

The underwater site of Rochelongue, believed to be four small boats located west of Cap d’Agde in southwestern France and discovered in 1964, dates to about 600 BCE and its cargo included 800kg of copper ingots and about 1,700 bronze artifacts. They contain very pure copper with traces of lead, antimony, nickel and silver.

New crystal structure for hydrogen compounds for high-temperature superconductivity

Posted by in categories: computing, particle physics

Superconductivity is the disappearance of electrical resistance in certain materials below a certain temperature, known as “transition temperature.” The phenomenon has tremendous implications for revolutionizing technology as know it, enabling low-loss power transmission and maintenance of electromagnetic force without electrical supply. However, superconductivity usually requires extremely low temperatures ~ 30 K (the temperature of liquid nitrogen, in comparison, is 77 K) and, therefore, expensive cooling technology. To have a shot at realizing a low-cost superconducting technology, superconductivity must be achieved at much higher transition temperatures.

Materials scientists have had a breakthrough on this front with crystalline materials containing hydrogen, known as “metal hydrides.” These are compounds formed by a metal atom bonded with hydrogen that have been predicted and realized as suitable candidates for achieving even room-temperature superconductivity. However, they require extremely high pressures to do so, limiting their practical applications.

In a new study published in Chemistry of Materials, a group of researchers led by Professor Ryo Maezono from Japan Advanced Institute of Science and Technology (JAIST) performed to expand the search for high-temperature superconductors, looking for among ternary hydrides (hydrogen combined with two other elements).

Is There a Thing, or a Relationship between Things, at the Bottom of Things?

Posted by in category: quantum physics

The wildly inventive physicist John Wheeler was an early explorer of this notion. In a 1989 paper, “Information, Physics, Quantum: The Search for Links,” Wheeler takes a stab at “the age-old question: How come existence?” The answer, he speculates, might come from a fusion of physics and information theory. The former traffics in “its,” or physical things, and the latter in “bits,” defined as answers to yes-or-no questions.

Wheeler proposes that “every physical quantity, every it, derives its ultimate significance from bits, binary yes-or-no indications, a conclusion which we epitomize in the phrase, it from bit.” Noting the crucial role of measurement in the outcome of quantum experiments, Wheeler suggests that we live in a “participatory universe,” in which we bring the world into existence, and vice versa.

Picking up on Wheeler’s ideas, physicist Carlo Rovelli argues in a 1996 paper, “Relational Quantum Mechanics,” that quantum mechanics undermines “naive realism,” the notion that science discovers a reality that exists independently of our observation of it. He proposes what he calls a “relational” interpretation of quantum mechanics, which says things only exist in relation to other things. Rovelli notes that Galileo and Kant, among others, anticipated the relational perspective.

Elon Musk Named Time Magazine Person Of The Year

Posted by in categories: Elon Musk, space travel, sustainability

Time magazine on Monday named Tesla chief and space entrepreneur Elon Musk as its person of the year, citing his embodiment of the technological shifts but also troubling trends reshaping people’s lives.

Musk — who overtook Amazon founder Jeff Bezos this year to become the world’s wealthiest person — wields impact on Earth with his Tesla electric car company and beyond our planet with his SpaceX rockets.

“Musk’s rise coincides with broader trends of which he and his fellow technology magnates are part cause and part effect,” Time editor-in-chief Edward Felsenthal wrote.

New AI Research Could Enable Ocean Monitoring and Exploration

Posted by in categories: drones, robotics/AI

Further exploration of the unknown worlds of the deep sea may soon be possible, along with low-energy monitoring. Engineers at Caltech, ETH Zurich, and Harvard are developing an AI that will allow autonomous drones to navigate using the ocean’s currents rather than struggling to move through them.

According to one of the authors of a recent paper published in Nature Communications 0, John O. Dabiri, communications with robots exploring at depths of 20,000 feet is near impossible. They are difficult to control via joystick, and researchers are unable to feed them data about local ocean currents. So it becomes necessary for ocean-borne drones to be able to make their own decisions and move by themselves.

US tech investors believe they’re close to a cure for old age

Posted by in categories: biotech/medical, life extension

Contrary to what you may think, getting old is not inevitable. And by getting old, I mean the bad parts: weakened muscles, fading memory, aching joints … or perhaps a disease such as cancer or diabetes makes an unwelcome appearance.

James Peyer, 35, is out to prove that age is, instead, like polio or tuberculosis. Those and other infectious diseases once were the biggest killers, until we developed effective vaccines or treatments.

Why, asked Peyer, co-founder of the New York longevity start-up Cambrian Biopharma, should age be any different? “Of our 100,000-year-plus history as a species, it’s been for only about 75 years that these diseases of ageing have been the primary predators of humankind.” He added: “We are rapidly zeroing in on our biggest.
