U.S. generals planning for a space war they see as all but inevitable

Posted by in categories: military, space

A ship in the Pacific Ocean carrying a high-power laser takes aim at a U.S. spy satellite, blinding its sensors and denying the United States critical eyes in the sky.

This is one scenario that military officials and civilian leaders fear could lead to escalation and wider conflict as rival nations like China and Russia step up development and deployments of anti-satellite weapons.

If a satellite came under attack, depending on the circumstances, “the appropriate measures can be taken,” said Lt. Gen. John Shaw, deputy commander of U.S. Space Command.

Civilian Space Development has kicked-off: the work begins now!

Newsletter 17.09.2021 by Bernard Foing & Adriano V. Autino

During the last months we have seen the first civilian passengers fly to space, onboard Blue Origin and Virgin Galactic vehicles. September 15th, four civilian astronauts, onboard a Space X Dragon capsule, passed the 500 km orbit, more than 100 km higher than the ISS.In 2016 we started to publicly talk about and promote Civilian Space Development, while the whole space community kept on talking only about space exploration. Earlier, in 2,008 we founded the Space Renaissance movement, and a couple of years later the Space Renaissance International, as a philosophical association targeted to complete the Kopernican Revolution, supporting the Civilization expansion into space. Nowadays the concept of civilian space flight is everywhere on the media, and many people in the space community talk about a space renaissance. Of course the Coronavirus pandemics accelerated the awareness of the urgency to expand humanity into outer space. And space tourism — the first stage of civilian space settlement — is now a reality, in its first steps.

Of course nobody could be more happy than ourselves, for the above development, and of course**2 we want to congratulate with Elon, Richard and Jeff, for such a great achievement!

Cold War nuke tests changed rainfall

Posted by in categories: military, physics

The study, published in Physical Review Letters, used historic records between 1962–64 from a research station in Scotland. Scientists compared days with high and low radioactively-generated charge, finding that clouds were visibly thicker, and there was 24% more rain on average on the days with more radioactivity.

Professor Giles Harrison, lead author and Professor of Atmospheric Physics at the University of Reading, said: By studying the radioactivity released from Cold War weapons tests, scientists at the time learnt about atmospheric circulation patterns. We have now reused this data to examine the effect on rainfall.

The politically charged atmosphere of the Cold War led to a nuclear arms race and worldwide anxiety. Decades later, that global cloud has yielded a silver lining, in giving us a unique way to study how electric charge affects rain.

Armed Forces to trial laser weapons for the first time

Posted by in category: military

Trials will take place in 2023 of laser and radio frequency weapons mounted on a Type-23 frigate and a Wolfhound vehicle, Jeremy Quin will say. Full capabilities are expected to be in service within 10 years.

British Army and Royal Navy will mount high-tech weapons on Wolfhound vehicle and Type-23 frigate, with aim of full capabilities in 10 years.

The Pentagon Wants to Launch a Nuclear Thermal Rocket in 4 Years

Posted by in categories: existential risks, military, robotics/AI, satellites

The spacecraft will provide fast transport between Earth and the moon—and beyond.

Picture this: World War III is just hours away. In the cold vastness of space, enemy robotic spacecraft are slowly adjusting their orbits and preparing to launch a surprise attack on the U.S.’s fleet of satellites. The uncrewed craft, with robotic arms strong enough to disable a satellite, are creeping up on American spacecraft, about to deal a knockout blow to the U.S. military.

But down on Earth, U.S. Space Force guardians have been keeping track of the assassin craft, knowing that in order to present as low a profile target as possible, they have just enough fuel for one attack. At the last minute, after the enemy satellites have committed to attack, the command activates the nuclear thermal propulsion (NTP) engines on the American satellites, quickly boosting them into a higher orbit and safely out of range.

New laser captures energy like noise-cancelling headphones

Posted by in categories: biotech/medical, military

Physicists at The Australian National University (ANU) have developed extremely powerful microscopic lasers that are even smaller than the wavelength of the light they produce. So called ‘nanolasers’ have a huge variety of medical, surgical, industrial and military uses, covering everything from hair removal to laser printers and night-time surveillance. According to lead researcher Professor Yuri Kivshar, the nanolasers developed by his team promise to be even more powerful than existing lasers, allowing them to be useful in smaller-scale devices. “They can also be integrated on a chip,” he said.
