NASA: Navigation failure caused the mission of the "Wit" Mars helicopter to end. NASA said on December 11 that the investigation and evaluation of the "Wit" Mars helicopter showed that the navigation system failure was the cause of the rotor damage and the end of the mission during its landing. The "Wit" helicopter landed on Mars with the American "Perseverance" rover on February 18th, 2021. It weighs about 1.8 kilograms, has four rotors, and is powered by solar panels for lithium batteries. On April 19th of the same year, Wit completed its first flight on Mars. On January 18th this year, Wit made its 72nd and last flight to Mars. Because its rotor blades were damaged during the landing, it could not fly again, and NASA announced the end of its mission. On the 11th, NASA announced the investigation results of the last flight of Wit. The evaluation shows that the navigation system of "Wit" can't provide accurate data during its flight, causing a series of failures, leading to the end of its mission.

On December 12, according to the latest research of TrendForce Jibang Consulting, in November 2024, the sales of electric vehicles in China continued to increase, which boosted the demand for power batteries, and the price of Ferrous lithium phosphate batteries remained stable, while the ternary batteries declined slightly. The demand for batteries in the energy storage market maintained the peak season characteristics, and with the price advantage of large-capacity batteries, the proportion of shipments increased. However, the average price of energy storage batteries continued to decline in November due to the slowdown in demand for orders at the end of the year. The agency expects that the price of some lithium battery materials may rise slightly in the peak season of 2025, which is expected to repair the serious losses of the company in the early stage. However, due to the fact that the relationship between supply and demand has not changed from surplus to shortage, the expected increase in material prices is limited, and battery manufacturers actively control costs, the battery price trend will be stable next year.Speaker of South Korea's National Assembly: Yin Xiyue will never tolerate declaring martial law in order to warn the National Assembly.
