我国航天器首次观测到星际天体：天问一号传回阿特拉斯（3I/ATLAS）新照片！该天体可能比太阳系年龄还老

Core Insights - The Tianwen-1 orbiter successfully observed the interstellar object Atlas (3I/ATLAS), marking the first time a Chinese spacecraft has observed an interstellar body [1] - Atlas was discovered on July 1, 2025, by a survey telescope in Chile and is the third known interstellar object to visit the solar system, potentially older than the solar system itself [1] - The observation was conducted from approximately 30 million kilometers away, making Tianwen-1 one of the closest detectors to the object [1] Group 1 - The observation of Atlas is a significant extension of the Tianwen-1 mission, providing technical trials for future asteroid exploration with Tianwen-2 [5] - The Tianwen-1 team began preparations for the observation in early September, facing challenges due to the object's distance, speed, and small size [5][6] - The high-resolution camera on Tianwen-1 was originally designed for capturing bright Martian surfaces, making this the first attempt to photograph such a distant and faint target [5][6] Group 2 - The observation required extensive simulations and calculations to assess feasibility, leading to the successful design of a key imaging strategy [6] - Tianwen-1 has been operational since February 2021, maintaining a stable status for 4 years and 8 months [6]
