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.

Recently, Intel OEM announced a major breakthrough in on-chip interconnection technology. The latest subtractive Ruthenium interconnection technology of the company can reduce the inter-line capacitance by up to 25%, effectively improving the on-chip interconnection. According to reports, the subtractive ruthenium interconnection technology has achieved great progress in interconnection miniaturization by using ruthenium, a new, key and alternative metallization material, and using thin film resistivity and airgap. This process does not need an expensive photolithographic air gap exclusion zone around the via, and it can also avoid using a self-aligned via that is selectively etched. When the spacing is less than or equal to 25 nm, the air gap realized by reducing ruthenium interconnection technology can reduce the capacitance between lines by up to 25%, which can be used as a metallization scheme to replace copper damascene process in closely spaced layers. It is reported that this solution is expected to be applied in the future process nodes of Intel OEM. (Sina Technology)
