China data link could offer faster coordination during hypersonic attacks

China’s military data link could offer faster coordination during hypersonic attacks.

Chinese researchers explain that traditional tactical data links rely on round-trip time (RTT) for synchronization, which works for low-speed aircraft. Systems like NATO’s Link-16 achieve roughly 100-nanosecond accuracy under these conditions.

However, in hypersonic cooperative strike systems operating above Mach 5, the rapid relative motion between widely dispersed platforms creates asymmetric transmission paths, severely reducing the precision of conventional RTT algorithms. This highlights the need for new communication technologies capable of maintaining ultra-precise timing at extreme speeds.

STAR Data Reveal ‘Splash’ of the Quark-Gluon Plasma

Many groups of scientists studying jets at RHIC have focused on a phenomenon known as jet quenching, an apparent suppression of energetic jets emerging from the QGP. The idea is that jets are losing energy through their interactions with the QGP.

RHIC’s measurements of jet quenching to date have focused primarily on the most energetic, leading jet particles, because they are straightforward to measure. However, such leading particles provide only limited insight into the process. The new results from STAR reconstruct a wider correlated spray of particles making up the jets, revealing much more detail about how the QGP is “excited” and responds to the jet — and where the “lost” energy goes.

The new analysis, for the first time, included the reconstruction of jets produced back-to-back with photons.

Asteroid Bennu Is A “Frankenstein’s Monster” Of Material From The Inner Solar System, Outer, And Beyond

Ryugu is another asteroid for which we have a sample, collected by the Hayabusa-2 mission. Despite their differences, Ryugu and Bennu also share similarities, and Ryugu, too, had plenty of organic materials, simply not as much of them.

Bennu’s parent body seems to have formed from a really different set of materials from across the Solar System, and it might have formed further away from the Sun, too.

“We’re looking at unique snapshot of the outer solar system at the birth of our Sun,” said Professor Sara Russell, planetary scientist at the Natural History Museum, and co-author on the paper. “Some of these grains have survived billions of years of solar system evolution almost untouched and can tell us more about the environment in which planets were born.”
