越南地球观测卫星“微龙”号升空 将提高应对自然灾害和气候变化的能力

据报道,微龙号卫星设计重量为50公斤,大小50×50×50厘米,由爱普瑟隆4号火箭( Epsilon-4 rocket )从位于日本鹿儿岛县的内之浦宇宙空间观测所(Uchinoura Space Center)发射至预定轨道。

微龙号卫星旨在监测沿海地区的水质,确定渔业资源,并观测海洋变化,以协助越南的水产养殖业。 该卫星将定位并提供有关诸如石油泄漏等灾难事件的准确信息。该卫星还将测量悬浮在地球大气层中的气溶胶,微粒子的浓度。此外,微龙号卫星旨在促进与全球微卫星社区的数据交换,以支持全球应对气候变化和灾害的努力。

微龙号卫星的发射是日本政府资助的利用地球观测卫星预防灾难和气候变化项目的一部分。微龙号卫星由来自越南国家航天中心(VNSC)的36名工程师开发,他们被派往日本学习太空技术,包括东京大学、庆应义塾大学、北海道大学、东北大学和九州工业大学。该卫星将由越南国家航天中心运营。

日本宇宙航空研究开发机构(JAXA)将微龙号与其他六颗日本卫星一起发射进入轨道。该卫星也被称为创新技术示范卫星,它将对轨道上的组件进行测试,以便在未来的任务中使用。

A new Earth observation satellite developed by Viet Nam, which aims to enhance the country’s ability to respond to disasters and climate change, was launched into space on 18 January 2019. The MicroDragon satellite was put into orbit via an Epsilon-4 rocket, which lifted-off from the Uchinoura Space Centre in Kagoshima Prefecture in Japan.

The satellite is designed to monitor the quality of water in coastal areas, locate fishery resources, and observe changes in the ocean to assist Viet Nam’s aquaculture sector. MicroDragon will locate and provide accurate information on disasters such as oil spills. The satellite will also measure the concentration of aerosols, microscopic particles suspended in the Earth’s atmosphere. Moreover, MicroDragon aims to contribute to data exchange with the global microsatellite community to support the global response to climate change and disasters.

The launch of the MicroDragon satellite is part of a project on disasters and climate change prevention using Earth observation satellites funded by the Government of Japan. MicroDragon was developed by 36 Vietnamese engineers from the Vietnam National Space Centre (VNSC), who were sent to study space technology in Japan; namely the University of Tokyo, Keio University, Hokkaido University, Tohoku University and Kyushu Institute of Technology. The satellite will be operated by the VNSC.

The Japan Aerospace Exploration Agency (JAXA) launched MicroDragon into orbit along with six other Japanese satellites. The primary payload for the launch was the Rapid Innovation Payload Demonstration Satellite-1 (RAPIS-1) for JAXA. Also known as the Innovative Technology Demonstration Satellite, the satellite aims to test components in orbit for potential use on future missions.
