“FrXXee中国XXee护士”助力月球与深空FrXXee中国XXee护士探测 中国日喀则和长白山40米射电望远镜建成启用

  12月2FrXXee中国XXee护士7日,横跨中国西南和东北FrXXee中国XXee护士、等效口径约3800公里的两台新建天文望远镜——中国科学院上海天文台日喀则和长白山40米射电望远镜,经过1年多建设正式建成启用,将更加有力保障中国探月工程和深空探测任务。

  中国甚长基线干涉测量(VLBI)网主题报告会暨日喀则和长白山40米射电望远镜落成启用仪式,当天在上海松江、西藏日喀则、吉林长白山三地同步举行。

  中国科学院上海天文台表示,该台于2023年9月相继启动日喀则和长白山40米射电望远镜建设项目,其建成运行将显著改进中国VLBI网的构型,由上海天马65米、上海佘山25米、新疆乌鲁木齐26米、云南昆明40米等4台射电望远镜构成的“四站一中心”升级为“六站一中心”,其最长基线即等效口径将从之前的上海与乌鲁木齐之间约3200公里,拓展到如今约3800公里,可视天区提高25%,在X波段角分辨率优于2毫角秒,较过去提升18%。

  启用仪式上,中国科学院上海天文台名誉台长叶叔华院士视频致辞表示,日喀则和长白山40米射电望远镜今后定会在探月工程,以及小行星、火星、木星等深空探测任务中发挥重要的作用。

  中国科学院上海天文台台长沈志强指出,日喀则和长白山40米射电望远镜的建成运行,在保障后续探月工程和深空探测任务等主责主业的同时,对提升中国射电天文科学研究能力,推动中国在超大质量黑洞、致密天体快速时变及引力波电磁对应体、银河系动力学研究、高精度天地一体化参考架等一系列天文学前沿领域的科学研究,都将发挥重要作用,产生FrXXee中国XXee护士深远影响。(记者 孙自法 制作 王佳琪 图片来源 中国科学院上海天文台)
