一箭七星！力箭一号运载火箭发射看点解析

Core Viewpoint - The successful launch of the Lijian-1 Yao-10 rocket marks a significant advancement in China's commercial space capabilities, with the ability to deploy multiple satellites efficiently and cost-effectively [1][2]. Group 1: Launch Details - The Lijian-1 Yao-10 rocket successfully launched on August 19, carrying seven satellites into their designated orbits, achieving its flight test mission successfully [1]. - The rocket has now placed a total of 70 satellites into orbit, with a cumulative payload mass exceeding 7 tons [1]. Group 2: Cost Efficiency and Technological Innovations - The Lijian-1 rocket has reduced the cost of launching payloads to below $10,000 per kilogram through high-density and multi-satellite launches [2]. - The rocket's capacity for launching satellites has increased, with a capability of 1.5 tons to a 500-kilometer sun-synchronous orbit, allowing for the launch of over 50 satellites in a single mission [2]. Group 3: Satellite Specifications - The Zhongke Satellite 05, one of the payloads, features an X-band synthetic aperture radar with an imaging resolution better than 1 meter and a maximum observation width exceeding 300 kilometers [2]. - The Tianyan 26 satellite is a lightweight commercial satellite designed for "visible light + infrared remote sensing" [3]. - The ThumbSat satellites (ThumbSat-1 and ThumbSat-2) aim to validate low-orbit communication capabilities and payload image transmission performance for future international cooperation in educational and scientific fields [3].
