Fighter engine-size hypersonic ground demonstrator construction plans moving ahead
Posted by Klaus Baldauf in categories: military, space, surveillance
SABRE is at heart a rocket engine designed to power aircraft directly into space (single-stage to orbit) to allow reliable, responsive and cost effective space access, and in a different configuration to allow aircraft to cruise at high speeds (five times the speed of sound) within the atmosphere.
If the rocket for space is not used then the US air force could use Skylon and SABRE engine technology to develop a 4000 mph hypersonic fighter plane or spy plane.

China’s Newly Launched SpaceLab Empowers Human Brain/Computer Interaction –“Can Transmit Astronauts’ Thoughts into Operations”
Posted by Karen Hurst in categories: computing, neuroscience, space
No surprise; we knew this was going to happen.
China launched its second space lab, Tiangong-2, on Thursday, paving the way for a permanent space station that the country plans to build around 2022. In a space science first, a human brain-computer interaction test system, developed by Tianjin University, has been installed in the lab and it is set to conduct a series of experiments in space, People’s Daily reported. According to Ming Dong, the leader of the research team in charge of the brain-computer test system, the brain-computer interaction will eventually be the highest form of human-machine communication.

Elon Musk next big rocket will be called the Interplanetary Transport System as he eyes solar system colonization
Posted by Klaus Baldauf in categories: Elon Musk, space, transportation
However, he tweeted the name of his new megaspaceship will not be the Mars Colonial Transport it will be the interplanetary transport system. Elon plans to go beyond Mars to the entire solar system.
Mars isn’t the solar system’s only marginally habitable world for would-be new world colonists. The Moon, Venus, the asteroid Ceres, Titan and Callisto all have some advantages that could allow for colonies to subsist. Musk now seems to be suggesting that some of these more distant destinations, especially moons around Jupiter and Saturn, might be reachable with the Interplanetary Transport System.

Physicists Are Close to Producing Metallic Hydrogen, And It Could Change Everything
Posted by Elmar Arunov in categories: evolution, physics, space
The implications of the discovery of hydrogen in a metallic form make it a subject of great fervor. Teams are racing toward its use as a superconductor as well as a means of better understanding the universe.
The simplest and most common element, first in the periodic table, shouldn’t be difficult to crack, right? “What could be more simple than an assembly of electrons and protons?” asks Neil Aschcroft, a theoretical physicist at Cornell University. Yet, its supposed metallic form is quite the opposite. Apparently, the physics of hydrogen becomes more complex at high pressures. A sort of mega-evolution.
Hydrogen is naturally at a gaseous state, at room temperature and under atmospheric pressure. But hydrogen becomes solid, given enough of a forceful squeeze or at low temperatures. It also can transform into a liquid, if heat is added while squeezing. What is more confounding is the supposed ability of hydrogen, theoretically, to transform into metal if more extreme conditions are applied.

New Laser Provides Ultra-Precise Tool for Scientists Probing the Secrets of the Universe
Posted by Karen Hurst in categories: particle physics, quantum physics, space
WASHINGTON — Researchers have developed a new laser that makes it possible to measure electron transition energies in small atoms and molecules with unprecedented precision. The instrument will help scientists test one of the bedrock theories of modern physics to new limits, and may help resolve an unexplained discrepancy in measurements of the size of the proton.
The team will present their work during the Frontiers in Optics (FiO) / Laser Science (LS) conference in Rochester, New York, USA on 17 −21 October 2016.
“Our target is the best tested theory there is: quantum electrodynamics,” said Kjeld Eikema, a physicist at Vrije University, The Netherlands, who led the team that built the laser. Quantum electrodynamics, or QED, was developed in the 1940s to make sense of small unexplained deviations in the measured structure of atomic hydrogen. The theory describes how light and matter interact, including the effect of ghostly ‘virtual particles.’ Its predictions have been rigorously tested and are remarkably accurate, but like extremely dedicated quality control officers, physicists keep ordering new tests, hoping to find new insights lurking in the experimentally hard-to-reach regions where the theory may yet break down.
