SpaceX test fires the massive new engine for its next big rocket

by Larra Morris

SpaceX has just completed its first test fire of a full-scale Raptor engine, which will be used to power the company’s next generation rocket. The news was announced by SpaceX CEO Elon Musk, who posted a pair of videos on Twitter of the engine being test fired at the company’s test sight in McGregor, Texas. The Raptor engine is currently being developed as a successor to the company’s existing Merlin 1D engine, and is expected to eventually power the company’s Starship to the Moon, to Mars, and beyond.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
