<p><b>金蟾部署任务-02</b>是广寒计划的第二艘金蟾转移级部署任务。2024 年 12 月 23 日 14:23<a href="/home/Launch_Vehicles/CZ-10E">长征十号戊型运载火箭</a><a href="/home/Spacecraft/Jinchan_Transfer_Stage">金蟾二号</a>送入近地轨道 400×400 km——与金蟾一号(<a href="/home/mission/Guanghan_Program/JC-01">金蟾部署任务-01</a>,2024 年 6 月 17 日发射)相同的停泊轨道。金蟾部署任务-02 发射时正值 <a href="/home/mission/Guanghan_Program/GHC-05">广寒基地建设任务-05</a> 任务期间:广寒 03 模块已于前一日(12 月 23 日 01:11)由冰轮三号搭载着陆于东方海,广寒基地建设任务-05 乘组正准备开始广寒 03 四个新舱段的卸货与安装作业。</p>
<p>金蟾二号入轨后进入待命状态,与已在轨运行半年的金蟾一号形成双金蟾编队。自此广寒物流体系首次具备 <b>并行运输能力</b>——一艘金蟾可在 LLO 装载月面燃料时,另一艘在 LEO 装载地球上行模块,物流循环周期从单金蟾的约 25~30 天缩短至约 15~18 天。</p>
<section class="infobox-overlap-section" aria-labelledby="background">
<h2 id="background">任务背景</h2>
<p><a href="/home/mission/Guanghan_Program/JC-01">金蟾部署任务-01</a> 部署金蟾一号后,广寒计划物流链的运力瓶颈逐渐显现。从 <a href="/home/mission/Guanghan_Program/GHC-03">广寒基地建设任务-03</a>(2024 年 7~8 月,金蟾一号首次执行物流循环但出现液氢保温异常)到 <a href="/home/mission/Guanghan_Program/GHC-04">广寒基地建设任务-04</a>(2024 年 9~11 月,金蟾一号完成修复并执行两次 LLO↔LEO 往返),单艘金蟾的运力可以支撑当前的基地扩建节奏——但无法同时支持月面燃料下行与地球模块上行。随着广寒基地进入大规模扩建阶段(广寒 03~07 模块的陆续发射),物流需求将大幅增长。</p>
<p>金蟾部署任务-02 的部署时机与 <a href="/home/mission/Guanghan_Program/GHC-05">广寒基地建设任务-05</a> 任务同步——金蟾二号入轨当日,广寒基地建设任务-05 正在月面安装广寒 03 模块。这一安排确保在后续 <a href="/home/mission/Guanghan_Program/GHC-06">广寒基地建设任务-06</a> 展开广寒 04 模块部署时,双金蟾编队已就位,可独立承担 LEO 货运转运与 LLO 燃料加注两项并行任务。金蟾二号与金蟾一号在设计和接口上完全一致——干重 8 吨、最大燃料容量 98 吨液氧甲烷、2 台 Hecate 液氧液氢发动机——确保维护流程和乘组操作无需额外训练。</p>
</section>
<h2 id="details">任务详情</h2>
<h3>发射与部署(12 月 23 日)</h3>
<p><a href="/home/Launch_Vehicles/CZ-10E">长征十号戊型运载火箭</a> 于 2024 年 12 月 23 日 14:23 从文昌发射场发射<a href="/home/Spacecraft/Jinchan_Transfer_Stage">金蟾二号</a>。为适配长征十号戊型运载火箭在航区回收模式下的运力限制(LEO 55 吨),发射时金蟾二号仅携带入轨和初期姿态维持所需的最小燃料量(约 15 吨液氧甲烷),干重约 8 吨,发射总质量约 23 吨——远在长征十号戊型运载火箭运力范围内。</p>
<p>一级采用航区回收模式——9 台 YF-150 液氧煤油发动机关机后一级沿发射方向惯性飞行,栅格翼展开后降落在海上回收驳船。二级 YF-215X Vac 发动机完成入轨推进后,金蟾二号与二级分离,以自身 Hecate 发动机完成轨道圆化——进入 400×400 km 圆形停泊轨道。金蟾二号太阳能电池板展开、航电系统自检通过后,进入低功耗待命模式,等待后续任务的燃料补给和物流指令。</p>
<h3>双金蟾并行物流</h3>
<p>金蟾二号入轨后,广寒物流体系形成了以下并行运输能力:</p>
<ul>
<li><b>金蟾一号</b>(2024 年 6 月部署,已累计完成 3 次 LLO↔LEO 往返):经 <a href="/home/mission/Guanghan_Program/GHC-03">广寒基地建设任务-03</a> 在轨维修后运行稳定。<a href="/home/mission/Guanghan_Program/GHC-05">广寒基地建设任务-05</a> 期间(2024 年 12 月)执行了广寒 03 模块的 LEO→LLO 转运。</li>
<li><b>金蟾二号</b>(2024 年 12 月部署):入轨后待命。在后续任务(<a href="/home/mission/Guanghan_Program/GHC-06">广寒基地建设任务-06</a> 起)中可与金蟾一号交替或并行执行物流循环——一艘在 LLO 接收月面冰轮上行燃料,另一艘在 LEO 接收地球长征十六号运载火箭上行模块,物流周期从单金蟾的约 25~30 天缩短至约 15~18 天。</li>
</ul>
<p>双金蟾编队的核心价值在于<b>消除物流等待时间</b>。在单金蟾作业模式下,一个月面燃料上行任务 + 一个地球模块上行任务需要金蟾在 LLO 和 LEO 之间往返两次(LLO→LEO→LLO→LEO),总周期约 45~55 天。双金蟾模式下,两艘金蟾各自独立执行一条航线——金蟾一号(LLO↔LEO 燃料下行)+ 金蟾二号(LEO↔LLO 模块上行)——两条航线可在同一窗口周期内并行完成,总周期压缩至约 20~25 天。</p>
<p>金蟾三号(JC-03)将在后续任务中部署,届时三艘金蟾可实现"一艘在 LLO 装燃料、一艘在 LEO 装模块、一艘在途"的完全并行物流模式。</p>
<h2 id="achievements">任务成果</h2>
<ul>
<li><b>双金蟾编队形成</b>:金蟾二号与已在轨半年的金蟾一号在 LEO 400×400 km 轨道会合,广寒物流体系首次具备并行运输能力。</li>
<li><b>长征十号戊型运载火箭第三次成功发射</b>:进一步验证了长征十号戊型运载火箭在航区回收模式下的发射可靠性,为后续金蟾三号部署奠定了基础。</li>
<li><b>物流周期大幅缩短</b>:双金蟾并行模式下,单次物流循环周期从单金蟾的约 25~30 天缩短至约 15~18 天,完全并行模式下可进一步压缩至约 20~25 天,大幅提升地月物资周转效率。</li>
<li><b>支持大规模基地扩建</b>:金蟾二号入轨与 <a href="/home/mission/Guanghan_Program/GHC-05">广寒基地建设任务-05</a> 广寒 03 模块安装同步,为后续 <a href="/home/mission/Guanghan_Program/GHC-06">广寒基地建设任务-06</a> 广寒 04 模块部署提供了双线物流保障,确保月面基地扩建与地月物资运输同步推进。</li>
