今年，一批商业火箭、商业卫星将陆续升空，中国航天正迎来"技术突破"和"规模爆发"双重拐点。 2015年，国家发展改革委等多部门联合颁布《国家民用空间基础设施中长期发展规划（2015—2025 年）》。这一年，被业内称为"中国商业航天元年"，商业航天发展迎来战略机遇期。 10年来，从基础设施建设到在轨卫星数量，从科技创新水平提升到人才体系建设，我国商业航天政策体 系持续完善、应用场景不断拓宽、全产业链快速发展，曾经遥不可及的航天科技，正借助商业力量走进 千家万户，赋能千行百业。 构建多元竞合新生态 与传统航天工业单纯依靠国家投入与牵引的单轮驱动模式不同，商业航天的显著特点是实现国家战略与 经济效益的双轮驱动。经过多年探索，我国商业航天参与主体日益多元，不仅有承担战略科技重任的国 家队，更有混合所有制企业、民营企业等，构建起产业链完备、市场竞争充分的发展格局。 日前，中国航天科技集团有限公司第六研究院自主研发的140吨级重复使用液氧甲烷发动机整机试验取 得圆满成功，标志着我国在开式液氧甲烷发动机领域达到新高度。该发动机将在天地往返运输系统、可 重复使用运载器以及大运力火箭等关键领域发挥核心作用，为商业航天发展筑牢 ...

昨天下午跳水的时候，是周内拿廉价筹码比较不错的一个节点，很可能接下来两天没有比它更好的了， 但是预期外的是尾盘啊又有资金回流抱团股。和讯投顾黄儒琛分析，明天创新药跟商业航天依然有轮动 预期。情绪上昨天是尾盘最后收的冰点，今天预期内是要接修复的，也确实接了上半场盘中一度收红 4000多家。如果你是一个拿捏短线情绪比较好的玩家，是不是又是一波兑付的机会？之后修复完再接强 分歧，节奏上再次回归题材间的轮动，那轮动到你的题材核心就兑付嘛跌下来，题材核心有低吸的机会 就继续做t不过有一点需要注意，如果没有尾盘抱团股的再次回流，那么明后两天可能就会进一步的在 抱团这里进行趋弱留强，然后资金去发掘新的题材方向，但事与愿违，坚持本周新题材不太会发育出来 的观点，数据反馈也比较一般，缩量1500多亿以及炸板率33个点，今天就是正常的轮动节奏不追高，你 想玩就考虑低吸即可。毕竟高位抱团品种的趋弱留强，再次强调仍在进行时。 今天实际跌停的5家品种也能获知这个信息，日内最强的题材是汽车零部件，首板13家没有领先题材身 位的品种，消息面的刺激是零部件厂商的应收账款周转天数下降，网约车运价从6月13号开始上调，以 及特斯拉6月22日无人 ...
