SRIC4 Newsletter #04 — What is Quality of Life?

What truly defines “Quality of Life” (QoL), and why we have titled the SRI IV World Congress on it?QoL is a broad concept, including all of the aspects of the life of us, human inhabitants of the third planet of this Solar System. Traditionally, we define QoL through the essentials—food, shelter, health, and education. These are the pillars of economic and cultural development, and they are non-negotiable. Yet, at Space Renaissance, we believe QoL aims higher. It is the freedom to pursue our highest ideals, to have a beautiful life, to explore spirituality, and to seek a global reduction in suffering. Interestingly, the perception of QoL varies wildly across our globe today. The Western post-industrial societies are often clouded by a lack of confidence and a fading hope for what lies ahead. The Eastern emerging societies, fueled by rapid industrial growth, look toward the horizon with immense anticipation. If we could measure QoL through the lens of hope, these emerging societies might actually outrank the West. Why? Because the belief that one is part of a “great project”—one that glorifies human intelligence and potential—is the ultimate antidote to social suffering.

Whether we progress or regress, fall into crisis or rise in a renaissance, it all depends on the mass-psychological mood of the people. When survival is secured, and economic growth creates opportunities for all, social fear dissolves. And as John Lennon famously sang, when fear fades, we finally “give peace a chance.”

We align ourselves with this progressive spirit, like a modern Promethean manifesto. However, we must be realistic: this hope has an expiration date. Without the launch of civil space development by 2030, the “closed world” will inevitably reach its limits. Eastern hopes will be dashed, and Western lifestyles will suffer a sharp decline.

Microbes harvest metals from meteorites aboard space station

If humankind is to explore deep space, one small passenger should not be left behind: microbes. In fact, it would be impossible to leave them behind, since they live on and in our bodies, surfaces and food. Learning how they react to space conditions is critical, but they could also be invaluable fellows in our endeavor to explore space.

Microorganisms such as bacteria and fungi can harvest crucial minerals from rocks and could provide a sustainable alternative to transporting much-needed resources from Earth.

Researchers from Cornell and the University of Edinburgh collaborated to study how those microbes extract platinum group elements from a meteorite in microgravity, with an experiment conducted aboard the International Space Station. They found that “biomining” fungi are particularly adept at extracting the valuable metal palladium, while removing the fungus resulted in a negative effect on nonbiological leaching in microgravity.

Neutrons Illuminate the Magnetic Dance of Chiral Phonons

Neutron scattering has provided a new and broader view of the twirling collective atomic vibrations in a magnetic crystal.

Phonons—quantized conveyors of sound and heat in solids—are usually visualized as collective vibrations in which atoms simply bounce back and forth, almost as if they were weights on springs. However, atoms can sometimes form “chiral phonons” that twirl and swivel clockwise or counterclockwise, in a way that resembles a coordinated dance [1]. When these circular, chiral motions entrain ionic charge, they generate a magnetic moment, which suggests that there might be a way to control sound and heat using magnetic fields. Until recently, this magnetic dance was primarily observed using optical techniques, granting access to only one corner of the “stage”—the point in the phonon’s momentum space where the momentum is nearly zero. Song Bao of Nanjing University in China and his collaborators have now broadened the view of momentum space by using inelastic neutron spectroscopy.

NASA’s MAVEN detects first evidence of lightning-like activity on Mars

While sifting through the extensive data collected by NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft over the last decade, scientists discovered a familiar type of electromagnetic signal commonly caused by lightning. This rare find represents the first direct indication of lightning activity on Mars. The team recently published their findings in Science Advances, where they describe the event and why it’s so difficult to detect lightning-like activity on Mars.

Whistler waves are low-frequency radio wave signals generated by lightning, which create an impulse that propagates through a planet’s magnetosphere, following along the magnetic field lines. The whistler waves disperse due to the slower velocity of the lower frequencies through the plasma of the ionosphere and magnetosphere. These waves are typical on Earth, but have also been observed on Jupiter, Saturn and Neptune. All of these planets all possess strong magnetic fields and corresponding magnetospheres, facilitating the movement of whistler waves.

Mars, on the other hand, does not have a global, Earth-like magnetic field. This is because the internal activity that causes these magnetic fields ceased on Mars billions of years ago. This may contribute to the fact that lightning-like discharges in the Martian atmosphere have not yet been observed. But lightning-like activity on Mars is not impossible.

3D printing with moon dirt for lunar habitats

“By combining different feedstocks, like metal and ceramics, in the printing process, we found that the final material is really sensitive to the environment,” said Sizhe Xu.

How can lunar regolith be used to construct future habitats on the Moon? This is what a recent study published in Acta Astronautica hopes to address as a team of scientists investigated novel methods for using lunar regolith for making structures on the lunar surface. This study has the potential to help scientists, engineers, mission planners, and future astronauts develop methods for working and living on the Moon, which comes as NASA’s Artemis program plans to land humans on the Moon in 2028.

For the study, the researchers examined how a laser 3D printing method called laser directed energy deposition (LDED) could be used for manufacturing structures using lunar simulant under a myriad of environments, specifically lunar conditions of zero atmosphere, oxygen, and complete vacuum. The lunar simulant used for the experiments is known as LHS-1 (lunar highland regolith simulants), with the lunar highlands being the lighter-colored mountainous regions of the Moon as seen from Earth, as opposed to the volcanic regions of the Moon that are darker in appearance.

Along with the environmental conditions, the researchers also examined how printing LHS-1 on various types of surfaces yielded different results. They also examined laser speed, scanning power, and the final microstructure products. In the end, the researchers found that alumina-silicate ceramic surfaces and high temperatures produced the most promising structures but cautioned that laboratory conditions vary from the real-world environment on the Moon.

MeerKAT discovers record-breaking cosmic laser halfway across the universe

Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected. It is located in a violently merging galaxy more than 8 billion light-years away, opening a new radio astronomy frontier.

Hydroxyl megamasers are natural “space lasers”—extremely bright radio-wavelength emissions produced when hydroxyl molecules in gas-rich, merging galaxies crash into one another. These cosmic collisions compress gas and stimulate large reservoirs of hydroxyl molecules to amplify radio emission.

The physical mechanism is very similar to lasers on Earth, but operates at a much longer wavelength of light of about 18 centimeters, rather than the optical light that our eyes can see. When this special radio light is exceptionally bright, it is termed a megamaser—a “cosmic beacon” that can be seen across vast stretches of the universe.

Astronomers shocked by how these giant exoplanets formed

JWST just found evidence that some “super-Jupiters” may have formed like planets, not failed stars. A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed like Jupiter, by slowly building solid cores. That’s unexpected because these planets are far bigger and orbit much farther from their star than models once allowed.

Gas giants are enormous planets made primarily of hydrogen and helium. They may contain dense central cores, but unlike Earth, they do not have solid surfaces you could stand on. In our solar system, Jupiter and Saturn are classic examples. Beyond our neighborhood, astronomers have identified many gas giant exoplanets, some far larger than Jupiter. The most massive of these worlds begin to resemble brown dwarfs, substellar objects sometimes called “failed stars” because they do not fuse hydrogen.

This overlap raises a major question in astronomy. How exactly do these massive planets form? One possibility is core accretion, the same process believed to have created Jupiter and Saturn. In this scenario, a solid core slowly builds up inside a disk of dust and ice, gathering rocky and icy material until it becomes massive enough to pull in surrounding gas. Another possibility is gravitational instability, where a swirling cloud of gas around a young star collapses quickly under its own gravity, forming a large object more like a brown dwarf.
