跨界选择 "很多人的航天梦是从小就有的，但我不是。"提起与卫星互联网的缘分，徐鸣回忆，自己对航天产生兴 趣始于2011年。当时，从安徽小山村走出来的徐鸣，尚埋首互联网创业。一个偶然的机会，他被旅行者 2号探测器拍摄的照片所震撼，对航天产生了兴趣。"读大学时，家里没信号也没网，一到假期就失 联。" 彼时，不只是小山村用不上网。截至2015年末，全球有41亿人无法接入互联网，目前这个数字虽已减少 到25亿人，但仍是一条巨大的数字鸿沟。而卫星互联网恰巧能解决这一问题。当徐鸣将他的目光投注于 航天科技时，全球商业航天的时代悄然到来，我国商业航天的大门正向民营企业打开。 "基于对政策、行业趋势和市场需求的判断，我深感机会来了，要抓住太空新基建的时代机遇！"2018年 4月，银河航天投入运营，开启硬核技术攻坚的征程。短短5年时间，我国首款使用柔性太阳翼的平板可 堆叠卫星——银河航天灵犀03星发射成功，这款卫星服务低轨道宽带通信，为我国巨型低轨通信星座的 快速部署提供了技术支撑。 此后，银河航天的技术突破一个接一个。2024年11月，长征十二号新型运载火箭成功将银河航天研制的 卫星互联网技术试验卫星送入预定轨道；12月，银 ...
