作者｜ 姚远 发自北京 编辑｜ 何子维 视觉 | 顾芗 58岁的杨毅强把自己比喻成一块高燃值的炭。 这是一个极具科学家特色的自我比喻。"燃值"，单位质量或体积燃料完全燃烧时释放的热量。 他说，如 果自己无法充分燃烧，燃烧成灰烬，"我会憋死的"。 他满鬓斑白，却神采奕奕，眼底有某种东西在强烈闪烁着。2018年，他就是这么说服了家人，告别航天 一院（即中国运载火箭技术研究院），来到中国科学院力学研究所任职空天飞行科技中心主任，创立国 内首家混合所有制火箭企业中科宇航，进军商业航天。 中科宇航创始人、董事长杨毅强 （受访者供图） 体制内工作的31年里，杨毅强曾任一院科研生产部部长、质量技术部部长、我国首型固体运载火箭长征 十一号首任总指挥等。这份工作如此稳定、体面、受人尊敬、成就斐然，令多少人艳羡——忽然要放弃 这一切，在52岁那一年，从头开始打拼，为什么？ 北京寒风凛冽。在中科宇航的亦庄办公室，杨毅强沏了一壶茶，热气腾腾的。他说，这一切都出自"热 爱与危机感"。 他太热爱航天，对它有太多的想法、规划和心愿。 热爱催生了危机感。 航天领域的竞争，早已告别了国家与国家之间倾注举国之力施行竞争的传统时期， 悄然进入了在 ...
