The approach mitigates risk and enables easy adoption. The RAD510 computer board will launch in industry-standard 3U form factor and use software compatible with the BAE Systems RAD750 and RAD5545 computer boards.

The RAD510 embedded computing board is for the challenging environment of radiation and extreme temperatures of space. It is built on the BAE Systems RAD750 computer board that has enabled more than 100 satellites.

Two companies to help Navy safeguard high-altitude sensitive electronics from electromagnetic pulse (EMP)

Posted by in categories: electronics, military

SAN DIEGO – U.S. Navy electronics experts are hiring two companies to develop enabling technologies to safeguard naval systems from the effects of high-altitude electromagnetic pulse (EMP).

Officials of the Naval Information Warfare Center Pacific in San Diego, announced estimated $12.5 million separate contracts Wednesday to Long Wave Inc. in Oklahoma City, Okla., and to Reliance Construction Co. in Cary, N.C., for high-altitude EMP hardening processes.

Laser, microwave, and other directed-energy weapons ready for the battlefield

Posted by in categories: drones, energy, military, surveillance

Perhaps no technology has shaped the 21st-century battlefield as profoundly as the drone. These uncrewed aerial vehicles (UAVs), along with their land and sea counterparts, have redefined the way wars are fought by providing military forces with unprecedented capabilities in surveillance, precision targeting, and intelligence gathering — all while reducing the risk to their own personnel. Drones have made complex operations more efficient and less costly, enabling militaries to strike with pinpoint accuracy and maintain a persistent presence over the battlefield.

As the century progresses, the influence of drones continues to expand beyond traditional state actors. Non-state groups and non-peer adversaries increasingly have adopted this technology, leveraging it to level the playing field in conflicts around the world. With commercial drones becoming more accessible, these actors can conduct reconnaissance, drop bombs, and challenge conventional military forces in ways that previously were unimaginable.

The influence of drones flows across all domains of warfare. Loitering munitions, or “Kamikaze drones,” have disrupted traditional force structures by providing smaller, more agile units with the ability to strike high-value targets such as tanks, artillery, and command centers.

This Planet Has Rings 200 Times Larger Than Saturn

Posted by in category: space

J1407b, has the largest ring system yet seen – around 200 times larger than Jupiter’s (the largest in our solar system). Its host planet is likewise massive: we don’t know whether it’s a gas giant or a brown dwarf. So far, it’s been classified as a super-Jupiter stellar body.

This is an updated (quotes and sources) version of the previous article.

NASA Admits Alcubierre Drive Initiative: Faster Than The Speed Of Light

Posted by in category: space travel

NASA is currently working on the first practical field test toward the possibility of faster than light travel. Traveling faster than light has always been attributed to science fiction, but that all changed when Harold White and his team at NASA started to work on and tweak the Alcubierre Drive.

Special relativity may hold true, but to travel faster or at the speed of light we might not need a craft that can travel at that speed. The solution might be to place a craft within a space that is moving faster than the speed of light! Therefore the craft itself does not have to travel at the speed of light from it’s own type of propulsion system. It’s easier to think about if you think in terms of a flat escalator in an airport.

‘Giant Arc’ Stretching 3.3 Billion Light-years Across The Cosmos Shouldn’t Exist

Posted by in categories: cosmology, mapping

A newly discovered crescent of galaxies spanning 3.3 billion light-years is one of the world’s largest known structures, challenging some of astronomers’ most fundamental assumptions about the universe.

The epic arrangement known as the Giant Arc is made up of galaxies, galaxy clusters, and a lot of gas and dust. It is located 9.2 billion light-years away and stretches across roughly a 15th of the observable universe.

Its discovery was “serendipitous,” according to Alexia Lopez, a doctoral candidate in cosmology at the University of Central Lancashire (UCLan) in the United Kingdom. Lopez was creating maps of things in the night sky using light from approximately 120,000 quasars, which are distant brilliant cores of galaxies where supermassive black holes consume material and produce energy.

Physicists Stir a Supersolid For First Time, Proving Its Bizarre Dual Nature

Posted by in category: quantum physics

Scientists on Wednesday said that they have successfully stirred a strange matter called a “supersolid” – which is both rigid and fluid – for the first time, providing direct proof of the dual nature of this quantum oddity.

In everyday life, there are four states of matter – solid, liquid, gas, and the rarer plasma.

But physicists have long been investigating what are known as “exotic” states of matter, which are created at incredibly high energy levels or temperatures so cold they approach absolute zero (−273.15 degrees Celsius or-459.67 degrees Fahrenheit).

Observations from JWST and Chandra reveal a low-mass supermassive black hole that appears to be consuming matter at over 40 times the theoretical limit

Posted by in categories: cosmology, evolution

Using data from NASA’s JWST and Chandra X-ray Observatory, a team of U.S. National Science Foundation NOIRLab astronomers have discovered a supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang that is consuming matter at a phenomenal rate — over 40 times the theoretical limit. While short lived, this black hole’s ‘feast’ could help astronomers explain how supermassive black holes grew so quickly in the early Universe.

Supermassive black holes exist at the center of most galaxies, and modern telescopes continue to observe them at surprisingly early times in the Universe’s evolution. It’s difficult to understand how these black holes were able to grow so big so rapidly. But with the discovery of a low-mass supermassive black hole feasting on material at an extreme rate, seen just 1.5 billion years after the Big Bang, astronomers now have valuable new insights into the mechanisms of rapidly growing black holes in the early Universe.

LID-568 was discovered by a cross-institutional team of astronomers led by International Gemini Observatory/NSF NOIRLab astronomer Hyewon Suh. They used the James Webb Space Telescope (JWST) to observe a sample of galaxies from the Chandra X-ray Observatory’s COSMOS legacy survey. This population of galaxies is very bright in the X-ray part of the spectrum, but are invisible in the optical and near-infrared. JWST’s unique infrared sensitivity allows it to detect these faint counterpart emissions.
