Core Viewpoint - Tesla is reviving its Dojo 3 supercomputer project, which was previously halted, indicating a significant shift in its chip strategy towards space AI computing [3][4][10]. Group 1: Dojo 3 Project Overview - Dojo 3 was initially designed as a supercomputer for machine learning training, with a focus on architecture restructuring and cost optimization [7]. - The project was paused five months ago due to a strategic decision to concentrate resources on AI5 and AI6 chips, moving away from developing custom chips [5][8]. - The revival of Dojo 3 is based on the successful progress of the AI5 chip design, with Tesla actively recruiting engineers for this initiative [5][8]. Group 2: Space AI Ambitions - The new mission for Dojo 3 includes advancing into "space artificial intelligence computing," aligning with Musk's vision of deploying AI computing centers in space [4][10]. - Musk believes that operating large-scale AI systems in orbit will be more cost-effective than on Earth within the next four to five years, leveraging solar energy and cooling technologies [11]. - This vision connects Tesla's various business interests, potentially positioning the company as a major beneficiary if successful [11]. Group 3: Challenges Ahead - Achieving the goal of space-based AI data centers faces significant challenges, including orbital debris, regulatory approvals, and international space policies [12]. - Cooling high-power computing devices in a vacuum presents practical difficulties, despite theoretical advantages [12][13]. - Constructing large AI data centers in geostationary orbit (GEO) is feasible but requires extensive infrastructure, which poses logistical and financial challenges [13][14].

Core Viewpoint - The article highlights the significant advancements in China's commercial space industry, particularly focusing on the construction of the first offshore liquid rocket launch and recovery test platform in Haiyang, Shandong, as part of the national goal to accelerate the establishment of a strong space power [1][2]. Group 1: Offshore Launch Platform Construction - The construction of the offshore liquid rocket launch and recovery test platform is underway at the Dongfang Spaceport in Haiyang, Shandong, marking a milestone in China's commercial space endeavors [2]. - The platform features a hydraulic pit that is seven to eight meters deep, equipped with four hydraulic vertical oil cylinders capable of rotating hundreds of tons of liquid rockets from horizontal to vertical positions for launch [3]. - A 17-meter deep flow channel is designed to direct the high-temperature rocket exhaust during ignition, utilizing a circular spray pipe to quickly cool the exhaust and reduce noise, thereby protecting the launch facilities [5]. Group 2: Operational Timeline and Testing - Over 150 workers are engaged in the construction, aiming to complete the platform and begin testing by around February 5, with a mainstream commercial liquid rocket scheduled for launch and recovery tests shortly after the Spring Festival [7]. - The Dongfang Spaceport has previously conducted 22 offshore launch missions using solid rockets, which, while flexible and mobile, have limitations in payload capacity and recovery [9]. Group 3: Advantages of Liquid Rockets - Liquid rockets offer greater payload capacity and the potential for reuse, significantly reducing satellite network costs, positioning them as the primary focus for domestic commercial space launches [11]. Group 4: Comprehensive Industry Layout - The Dongfang Spaceport is strategically located on an artificial island, approximately 3 kilometers from the mainland, ensuring safety due to the absence of fixed residents [12]. - The facility is designed with multiple functional areas, including a launch and recovery test platform and supporting fuel storage areas for liquid oxygen, liquid nitrogen, kerosene, and methane, essential for liquid rocket operations [14]. - As the only offshore launch mother port in China, the Dongfang Spaceport has successfully launched 137 satellites, contributing to a comprehensive industrial ecosystem in Shandong that integrates offshore launch leadership, collaborative rocket manufacturing, and space application expansion [16].
