印度空间研究组织（ISRO）近日宣布，其计划中的首个印度空间站——‘Bharatiya Antariksha Station’（印度空间站）的首个舱段将采用高强度铝合金制造。这一决定标志着印度在载人航天和长期轨道驻留能力方面迈出关键一步。铝合金因其轻质、高比强度、良好耐腐蚀性以及成熟的加工工艺，被广泛应用于国际空间站及各类航天器结构中。ISRO表示，选用特定型号的航空级铝合金不仅有助于减轻整体质量、降低发射成本，还能确保舱体在极端温差和微流星体撞击等太空环境中具备足够的结构完整性与安全性。首个舱段预计将在2035年前后发射，作为未来完整空间站的核心模块，支持宇航员生活、科学实验及与其他舱段对接。该空间站整体计划于2035年建成初期版本，并在2040年前完成全面部署。此举不仅彰显印度自主发展航天技术的决心，也将提升其在全球空间探索领域的地位。
The Indian Space Research Organisation (ISRO) recently announced that the first module of its planned indigenous space station—named the ‘Bharatiya Antariksha Station’—will be constructed using high-strength aluminum alloy. This decision marks a critical step forward in India’s ambition to develop human spaceflight capabilities and sustain long-term orbital presence. Aluminum alloys are widely used in spacecraft and the International Space Station due to their lightweight nature, high strength-to-density ratio, excellent corrosion resistance, and well-established manufacturing processes. ISRO stated that selecting specific aerospace-grade aluminum alloys will not only reduce the module’s overall mass and launch costs but also ensure structural integrity and safety under extreme space conditions, including thermal cycling and micrometeoroid impacts. The first module is expected to launch around 2035, serving as the core segment for astronaut habitation, scientific experiments, and future module docking. The initial version of the space station is targeted for completion by 2035, with full deployment anticipated by 2040. This initiative underscores India’s commitment to advancing autonomous space technology and elevating its role in global space exploration.
