SpaceX is upgrading its engines. A month after the company’s historic trip to the International Space Station, SpaceX says a new and improved version of its Merlin rocket engine has passed initial testing at its development facility in McGregor, Texas (video below).
And it’s turning out to be a rocket-engine-testing kind of week. Two other NASA-funded programs from Orbital Sciences and Boeing also tested new engines.

 Quickly and accurately identify inter-domain leakage issues in IC designsSponsored 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. |
