航空航天部门已经看到了几个3D printing-related milestones在过去一个月中宣布，从new bouncing space robotfor asteroid exploration to the launch of a开拓新的NASA卫星进入月球轨道。
现在已经揭示了两个新的发展NASA Kennedy Space Center, space technology design agencyAI SpaceFactory, and 3D printed rocket manufacturerRelativity Space。The former two have unveiled their designs forNASA’s3D打印的月球哨所丽娜（Lina），而相对空间已与太空通信公司签署了一项多发布协议Oneweb在2025年发射其低地轨道（LEO）卫星。
The LINA lunar outpost
莉娜的设计和测试是美国宇航局的一部分REACT project to advance the technologies and materials AI SpaceFactory created for the agency’s3D Printed Habitat Challenge。
美国宇航局目前正在几个项目create lunar structures, including a couple with Texas construction firm图标至3D打印火星栖息地这可以准确地重现未来宇航员访问火星表面并到达的条件添加性生产月球发射台由Lunar Regolith制成。
AI SpaceFactory’s original polymer, made with a martian regolith simulant, was modified to use actual lunar regolith and will be tested in a NASA vacuum chamber designed to simulate the environmental conditions on the moon.
测试阶段的结果将提供有关开发可持续3D打印系统的进一步信息，该系统能够在月球表面上构建大型结构，最终将用于打印LINA。
NASA and AI SpaceFactory have now revealed the designs for LINA, which will be constructed by autonomous robots on the south pole of the moon near the Shackleton crater. Near continuous sunlight on the crater’s peaks is predicted to provide solar power, while the shadow on the crater’s interior should enable the harvesting of water ice.
LINA is designed with 3D printed ‘Romanesque’ arches capable of withstanding high compressive loads with minimal material, which will be topped with 2.7 meters of lunar regolith to provide protection from radiation, micrometeorites, lunar seismic activity, and extreme thermal swings.
根据AI太空工厂的说法，其Regolith聚合物复合材料的强度将支持Lunar Outpost的几何形状，以创建可持续和持久的结构，可以支持长期居住以及潜在的未来前往其他星球的旅行。预计在今年晚些时候，真空室中的第一个测试印刷品预计。
AI SpaceFactory的首席执行官David Malott说：“我们的火星栖息地原型Marsha证明了与聚合物复合材料的3D打印是居住世界的强烈勾结。”“在充满大气压力或天气系统的环境中开发丽娜和印刷，通过新的环境，具有新的，更精确的变量，该技术通过新的环境发展。”
Relativity Space secures $1.2 billion launch contracts
Meanwhile, Relativity Space has brought the total backlog of launch contracts for its Terran R to $1.2 billion, after securing a multi-launch agreement with OneWeb. The Terran R is the firm’s first reusable, fully 3D printed launch vehicle slated for launch in 2025, proceeded by theoriginal Terran 1为其设定first orbital launch imminently。
Relativity Spaceraised $650 million为了加速去年6月的Terran R的生产，这将能够向Leo推出20,000公斤以上。Terran R是两阶段，216英尺高的火箭，直径为16英尺，有效负载整流罩能够超过Terran 1的轨道上的有效载荷20倍。
与OneWeb达成的多年启动服务协议将于2025年发射Terran R启动通信公司的LEO Gen 2卫星，从而为其现有的648卫星在轨道上增加了容量和新功能。Terran R将从Canaveral Space Force Station的相对空间站点启动OneWeb任务。
OneWeb的首席技术官Massimiliano Ladovaz说：“我们对这一协议以相对论感到兴奋。“相对论将为未来的发射计划增添新的能力。”
尽管Terran R距离发射还剩下数年，但OneWeb是第五个客户相对性空间为火箭服务提供的服务。多次发布协议导致该公司的积压总计超过12亿美元。
“We are honored to be chosen by OneWeb to help launch their Gen 2 constellation,” said Tim Ellis, Co-founder and CEO of Relativity Space. “They have an incredible team, technology, and momentum as a world leader in satellite connectivity with hundreds of operational satellites already in orbit. It is clear that more disruptive launch capacity of needed in the marketplace – Relativity is developing Terran R to fill this additional demand.
“We cannot wait to plan, execute, and successfully launch these missions together with OneWeb.”
