JAXA tests new rocket engine after failures; Beijing offers smart home subsidies

Japan's space agency, JAXA, conducted a successful test of its new "Epsilon S" rocket's second-stage engine. This test followed two previous failures in 2023 and 2024, and involved a modified engine and reduced payload capacity targets. Separately, the Beijing Municipal Bureau of Commerce announced subsidies for consumers purchasing 10 categories of smart home and robotics products, including humanoid robots and robot dogs, as part of a national policy to encourage equipment upgrades and trade-ins. In other news, Xiaohongshu denied rumors that its IPO was blocked due to an employee whistleblower, and Google's Gemini model reportedly fell out of the global top ten AI models. AI

IMPACT Beijing's subsidies may accelerate adoption of smart home devices and robots, while Google Gemini's reported drop in rankings highlights the competitive AI landscape.
