ISRO介绍称，执行这次发射任务的PSLV-DL型火箭起飞质量为260吨，高44.4米，计划飞行高度为 505.291公里。12日当天发射，该火箭顺利完成了前两级的飞行和分离，吸引了印度全国观众的目光。 然而，第三级点火后，任务控制中心一片寂静，没有任何遥测更新，证实了入轨失败。 【环球时报特约记者 晨阳】1月12日，印度技术最成熟的PSLV运载火箭执行今年首次航天发射任务， 结果遭遇失败。此次发射失败不但可能影响印度军用侦察卫星的部署计划，而且让印度航天界对PSLV 火箭顺利回归的期待成为泡影。 据《印度时报》12日报道，此次发射于当地时间上午10时18分在印度萨迪什·达万航天中心一号发射台 进行。这是印度2026年的首次卫星发射，印度空间研究组织（ISRO）希望借此重振外界对PSLV运载火 箭的信心。该火箭是ISRO的主力运载火箭，于1993年开始服役，并衍生出多个型号以适应不同的发射 任务。该火箭先后承担了2008年10月"月船一号"月球探测器、2013年11月"火星轨道探测器"以及2023年 9月印度首个太阳探测器"太阳神-L1"号等重大航天发射任务，并在2017年创下单次任务部署104颗卫星 的世界 ...
