China's move to restrict rare Earth minerals could have global implications.
A small asteroid, called 2025 TP5, will safely fly by our planet Oct. 15 at about a quarter of the distance to the moon.
Treasury Secretary Scott Bessent proposed a longer pause on high US tariffs on Chinese goods in return for Beijing putting off its recently announced plan to tighten limits on critical rare earths.
Shares of U.S. rare earth firms fell Tuesday after surging premarket—as stock indexes including the Dow and S&P 500 fell amid escalating trade tensions between the U.S. and China. USA Rare Earth plummeted over 7% after markets opened, despite surging in premarket.
The study found that, while in 2019 only 0.2% of satellites in Earth orbit were forced to perform more than 10 collision-avoidance maneuvers per month, that percentage had risen sevenfold by early 2025, to 1.4%. That number might still seem low, but it means that some 340 satellites spend a lot of time dodging debris and other spacecraft.
New research reveals that Earth’s continents owe their stability to searing heat deep in the planet’s crust. At more than 900°C, radioactive elements shifted upward, cooling and strengthening the landmasses that support life.
Think of it this way: only around 10,000 decently sized meteorites slam into Earth per year. Meanwhile, the planet is annually bombarded by as much as 40,000 tons of dust. Volume alone dictates that amino acids were attached to the latter debris instead of the former.
President Donald Trump called China's rare earth export controls a 'bad moment' as both countries navigate tensions over critical defense materials, and potential tariff increases.
