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.

Force Fields

Posted by in categories: media & arts, space

Force fields are a staple of science fiction, but usually regarded as only science fiction, not science fact. Today we’ll examine the notion and see what options we might have inside known science, as well as what alternatives might achieve similar effects.

See Hydrodynamic levitation at Cody’s Lab:

See India conduct first flight of autonomous technology demonstrator SWiFT

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

A scientist with the Aeronautical Development Establishment told Defense News that the flight test of the aircraft — also referred to as the Stealth Wing Flying Testbed, or SWiFT — took place to demonstrate its of ability to take off, climb in altitude, cruise midair, navigate to waypoints, descend and land autonomously.

He noted that the next step is to develop a proven autonomous combat surveillance platform. The scientist spoke on the condition of anonymity because he was not authorized to speak to the media.

The 1-ton SWiFT platform is powered by a Russian NPO Saturn 36MT turbofan engine. The platform had completed taxi trials in September 2021.

Keeping the energy in the room

Posted by in categories: innovation, space

It may seem like technology advances year after year, as if by magic. But behind every incremental improvement and breakthrough revolution is a team of scientists and engineers hard at work.

UC Santa Barbara Professor Ben Mazin is developing precision optical sensors for telescopes and observatories. In a paper published in Physical Review Letters, he and his team improved the spectra resolution of their superconducting sensor, a major step in their ultimate goal: analyzing the composition of exoplanets.

“We were able to roughly double the spectral resolving power of our detectors,” said first author Nicholas Zobrist, a doctoral student in the Mazin Lab.

‘Fossil Dwarf Galaxy’ Beneath Andromeda Could Hint at the Early Structure of the Universe

Posted by in category: space

Using the Victor M. Blanco Telescope, Donatiello captured minute glimpses of the galaxy in Chile, particularly at the Cerro Tololo Inter-American Observatory.

At the time, David Martinez-Delgado, another astronomer from Spain’s Instituto de Astrofisica de Andalucia, was conducting separate research regarding the lingering galaxies around Andromeda.

Upon learning the existence of the fossil galaxy, the scientists propose an argument that this could be a speck of an ancient galaxy. Its stars are said to be a former part of it.

‘Deepest image of our universe’ ever taken by Webb Telescope will be revealed in July

Posted by in category: space

We’re about to have an entirely new perspective on the universe.

The James Webb Space Telescope will release its first high-resolution color images on July 12. One of those images “is the deepest image of our universe that has ever been taken,” said NASA Administrator Bill Nelson during a news conference on Wednesday.

“If you think about that, this is farther than humanity has ever moved before,” Nelson said. “And we’re only beginning to understand what Webb can and will do. It’s going to explore objects in the solar system and atmospheres of exoplanets orbiting other stars, giving us clues as to whether potentially their atmospheres are similar to our own.”

Complete Chaos: Scientists Unravel the Early History of the Solar System

Posted by in category: space

An international team of researchers led by the ETH Zurich and the National Centre of Competence in Research PlanetS has more accurately recreated the early history of several asteroids than ever before. Their findings suggest that the early solar system was more chaotic than previously assumed.

Before the Earth and other planets formed, the young sun was surrounded by cosmic gas and dust. Slowly, rock shards of varying sizes formed from the dust over the millennia. Many of these became building blocks for subsequent planets. Others did not become planets and continue to circle the sun today, such as asteroids in the asteroid belt.

Iron samples from the cores of asteroids that had fallen on Earth as meteorites were analyzed by researchers from ETH Zurich and the National Centre of Competence in Research (NCCR) PlanetS in conjunction with an international team. In doing so, they revealed a portion of their early past during the formation of planets. Their results were recently published in the journal Nature Astronomy.

Another Primary Webb Space Telescope Instrument Gets the “Go for Science”

Posted by in categories: government, science, space

Recently, NIRISS, one of NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.”
