Space Pioneer’s Tianlong-3 Rocket Fails Launch, Setback for China’s Internet Satellite Ambitions

China’s Space Pioneer suffered a launch failure of its Tianlong-3 rocket on Friday, a setback for the country’s plan to build internet satellite networks. The 72-metre rocket was designed to rival SpaceX’s reusable Falcon 9, carrying 36 satellites per launch. An anomaly occurred during flight. The company is investigating. Previous tests also ended in explosion. China’s megaconstellations need reliable reusable rockets to compete with Starlink’s 10,000 satellites.

Harvard, TU Wien Unveil Racetrack Laser Producing Stable Mid‑Infrared Frequency Comb

Harvard and TU Wien have built a miniature racetrack‑shaped laser that creates stable frequency combs in the mid‑infrared. The device solves a long‑standing feedback problem that ruins standard combs. It could lead to chip‑scale gas sensors for greenhouse gas monitoring, industrial process control, or breath analysis. The work was led by Federico Capasso and published in Optica.
