7月23日,我國(guó)使用長(zhǎng)征二號(hào)丁運(yùn)載火箭,成功將商業(yè)航天企業(yè)銀河航天研制的靈犀03星發(fā)射升空,衛(wèi)星順利進(jìn)入預(yù)定軌道。靈犀03星是我國(guó)首款使用柔性太陽(yáng)翼的衛(wèi)星,單層柔性太陽(yáng)板厚度僅1毫米左右。
A Chinese commercial space company on Sunday launched a Long March-2D rocket, placing the Lingxi-03 satellite into preset orbit. The satellite, developed by the Chinese commercial space company, GalaxySpace, is the first of its kind in the country equipped with a flexible solar wing whose single-layer flexible solar panel is only approximately 1 mm in thickness.
【知識(shí)點(diǎn)】
靈犀03星配置了數(shù)十吉比特每秒容量的毫米波多波束數(shù)字載荷,用于驗(yàn)證下一代低軌寬帶衛(wèi)星通信以及超大能源、主動(dòng)熱控、工業(yè)一體化成型結(jié)構(gòu)、多星堆疊壓緊釋放等技術(shù),這也是我國(guó)首次在軌對(duì)多星堆疊發(fā)射技術(shù)進(jìn)行驗(yàn)證,將為我國(guó)巨型低軌通信星座的快速部署提供技術(shù)支撐。
作為我國(guó)首款使用柔性太陽(yáng)翼的衛(wèi)星,靈犀03星“柔性的翅膀”非常薄,單層柔性太陽(yáng)板厚度僅1毫米左右。據(jù)銀河航天有關(guān)負(fù)責(zé)人介紹,它可以像古代的“奏折”一樣折疊,裝在火箭里時(shí),為折疊狀態(tài),主體厚度僅為不到5厘米;在軌工作時(shí),“翅膀”拉開(kāi)長(zhǎng)度約9米,寬度超過(guò)2.5米。這種“柔性翅膀”具有包絡(luò)小、重量輕、模塊化等特點(diǎn),更易于收納,同樣質(zhì)量下面積更大,可以吸收更多太陽(yáng)能,適合衛(wèi)星大批量堆疊發(fā)射,對(duì)加速衛(wèi)星互聯(lián)網(wǎng)建設(shè)具有重要意義。
【重要講話】
近年來(lái),中國(guó)積極開(kāi)展空間探索活動(dòng),“嫦娥”攬?jiān)?、“天?wèn)”探火、“羲和”逐日、空間站巡天,不斷深化人類對(duì)宇宙的認(rèn)知,致力增進(jìn)人類共同福祉。
China has actively carried out space exploration missions in recent years, including the launches of Chang'e lunar probes, the Mars probe Tianwen-1, and the solar exploration satellite Xihe, as well as the construction of the country's space station. These missions have continuously deepened people's understanding of the universe and contributed to enhancing the well-being of humanity.
