The Dream of Building an Underground City on Mars (Sci-Fi Documentary)

Posted by in categories: education, environmental, habitats, robotics/AI, space

This is a sci-fi documentary, looking at what it takes to build an underground city on Mars. The choice to go underground is for protection, from the growing storm radiation that rains down on the surface every day. And to further advance the Mars colonization efforts.

Where will the materials to build the city come from? How will the crater be covered to protect the inhabitants? And what will it feel like to live in this city, that is in a hole in the ground?

Quantum computing offers new insight into photochemical processes

Posted by in categories: chemistry, computing, environmental, quantum physics

Quantum computing has provided new insights into a fundamental aspect of photochemical reactions that has previously proven difficult to study. The findings could improve scientists’ understanding of light-driven processes such as photosynthesis, smog formation and ozone destruction.

Photochemical processes occur when atomic nuclei and their electrons take on different configurations after absorbing a photon. Some of these reactions are guided by a quantum phenomenon called a conical intersection, where the potential energy surfaces that describe a molecule in its ground state and in its excited state converge. In these situations, quantum mechanical interference can prevent certain molecular transformations from taking place – a constraint known as a geometric phase. This limits the path that the reaction can take and affects the reaction outcome. The geometric phase has been known about since the 1950s, but due to the femtosecond timescales involved, it has never been directly observed in a molecular system.

Scientists use quantum device to slow down simulated chemical reaction 100 billion times

Posted by in categories: chemistry, computing, environmental, quantum physics, solar power

Scientists at the University of Sydney have, for the first time, used a quantum computer to engineer and directly observe a process critical in chemical reactions by slowing it down by a factor of 100 billion times.

Joint lead researcher and Ph.D. student, Vanessa Olaya Agudelo, said, It is by understanding these basic processes inside and between molecules that we can open up a new world of possibilities in , drug design, or harvesting.

How Theoretical Zero-Point Energy Draws Limitless Fuel From The Vacuum Of Space

Posted by in categories: environmental, robotics/AI, space

As sci-fi fans will attest, scenes of the distant future aren’t too difficult to imagine. We’ve got fleets of intergalactic ships exploring the inscrutable vastness of space. We’ve got legions of hardy settlers terraforming strange, new worlds. There’s a great galactic chain of humanity forged through will, knowledge, and intellect stretching across the Milky Way and beyond. At least, that’s one version. Some would describe a brutal, militaristic future for humanity, or one of disembodied consciousnesses and networks of planet-spanning artificial intelligence. But in each version, there’s one crucial element that humanity can’t do without: energy.

Energy is such a fundamental, critical component to civilization — off-world or not — that Soviet astronomer Nikolai Kardashev in 1964 labeled spacefaring civilizations based on how much energy they consumed; the higher the ranking, the more advanced, as explains. We’re talking far, far beyond crude fuel like oil and coal. Earth isn’t even a Type I civilization because we haven’t harnessed all the energy available on our own planet. By contrast, a Type II civilization would be able to build an energy-harnessing structure like a Dyson sphere around its own sun, as described in Popular Mechanics. After all, all those intergalactic ships, stations, settlements, etc., need power from somewhere, same as they need materials.

How to create an artificial magnetosphere for Mars

Posted by in categories: energy, engineering, environmental, space

Year 2023 face_with_colon_three

If humanity is ever to consider substantial, long-term colonization of Mars, the resources needed are going to be extensive. For a long-term human presence on Mars to be established, serious thought would need to be given to terraforming the planet. One major requirement for such terraforming is having the protection of a planetary magnetic field — which Mars currently does not have. The Earth’s magnetosphere helps protect the planet from the potential sterilizing effects of cosmic rays and also helps retain the atmosphere, which would otherwise by stripped by large solar storms as they pass over the planet. Mars does have small patches of remnant surface magnetic field, but these are localized in the southern hemisphere and are not of sufficient size or magnitude to protect the planet or a colony.

In this article we explore comprehensively for the first time, the practical and engineering challenges that affect the feasibility of creating an artificial magnetic field capable of encompassing Mars. This includes the concerns that define the design, where to locate the magnetic field generator and possible construction strategies. The rationale here is not to justify the need for a planetary magnetosphere but to put figures on the practicalities so as to be able to weigh the pros and cons of the different engineering approaches.

NASA’s Titan Dragonfly will touch down on a field of dunes and shattered ice

Posted by in categories: environmental, space

NASA’s Dragonfly mission to Saturn’s largest moon will touch down on a terrain of dunes and shattered, icy bedrock, according to a new analysis of radar imagery from the Cassini spacecraft.

Launching in 2027, Dragonfly is a rotorcraft that will arrive in 2034 and explore Titan from the air. Its range will be far greater than that of a wheeled rover, with Dragonfly capable of covering around 10 miles (16 kilometers) in each half-hour flight, according to NASA. Over the span of its two-year mission it will explore an area hundreds of miles or kilometers across. However, before taking to the sky on its own, Dragonfly must first arrive on Titan under a parachute, soft-landing on frozen terrain that is hidden from easy viewing by the dense hydrocarbon smog that fills the moon’s atmosphere.

Weather Control and Geoengineering

Posted by in categories: climatology, engineering, environmental, space

A look at advanced means of altering or controlling the planet’s climate and geography, drawing on concepts proposed for terraforming other planets. We look at existing and proposed ideas of controlling the weather, creating artificial islands or mountain ranges, using orbital mirrors and shades, and many other concepts.
