Semi High-Production Line Goes Live

Tesla has officially completed the first vehicle on its specialized high-production line for the Tesla Semi CleanTechnica. This milestone marks a transition from low-volume pilot builds to a facility reportedly capable of producing 50,000 units per year CleanTechnica. The move is critical for Tesla’s commercial vehicle ambitions, as the Semi has spent nearly a decade in various stages of development and testing with partners like PepsiCo and DHL CleanTechnica.

To support this scaling, Tesla is expanding its "Megacharger" infrastructure along major transit corridors, including California's I-5 and I-10 freeways CleanTechnica. These heavy-duty chargers are being installed at Pilot Travel Centers to facilitate long-haul electric trucking CleanTechnica. Analysts note that the Semi’s energy efficiency significantly outpaces diesel equivalents, offering a quiet, comfortable experience for drivers and a tight turning radius for maneuverability CleanTechnica.

SpaceX Sets Flight Record with CAS500-2

SpaceX launched a Falcon 9 rocket from Vandenberg Space Force Base at 11:59 p.m. PDT on Saturday, May 2 HarianBasis.co. The mission, designated CAS500-2, carried 45 satellites into low-Earth orbit, including a primary South Korean Earth-observation satellite AsatuNews.co.id.
