印度高中生设计全球最轻卫星2017年6月21日,在震耳欲聋的轰鸣声中,“卡拉姆号”和其他参与实验的卫星从美国宇航局(NASA)位于弗吉尼亚州瓦勒普斯岛发射升空。该卫星的主要目的是展示碳纤维3D打印技术的表现,检测3D打印的轻质外壳的持久性,证明碳纤维材料能否适应卫星发射和收回进程中的恶劣环境。一旦通过测验,这无疑将变成3D打印技术的一个新的里程碑。“卡拉姆号”卫星在发射后将进入亚轨道飞行,整个任务时长4小时。在这段时间内,卫星将在
Indian High School Student Designing Lightest Satellites in the World On June 21, 2017, in a deafening roar, “Calum” and other participating satellites from NASA in Vallerps, Virginia Launched off. The main objective of the satellite is to demonstrate the performance of carbon fiber 3D printing technology, to test the durability of 3D printed lightweight housings and to demonstrate the suitability of carbon fiber materials for harsh environments in satellite launch and retrieval processes. Once passed the test, this undoubtedly will become a new milestone in 3D printing technology. The satellite “Karam” will enter suborbital flight after being launched, and the entire mission will last for 4 hours. During this time, the satellite will be there
