As again, impressive documentary with lots of detailed information, great graphics, relevant supporting video snippets, fascinating storyline, etc. I am very impressed how this and other videos from this channel are put together. The details in each video are impressive. For example , the video mentioned how 4 different types of insulation tiles are used on the space shuttle. The video also showed photos of the space shuttle with the tiles, details of the tiles and the graphics of how the shuttle trembled during re-entry into the atmosphere. Great details and relevant graphics. Just imagine how much work is involved in putting together just one video. How many people are involved in making each video for the viewing pleasure of people interested in the scientific details of the topics discussed. Thanks for the great videos.
I feel the Chinese still have not mastered the landing part of the reusable rockets. Seems the software is unable to convincingly correct the landing. Recently I watched how SpaceX rockets land and it was super fast and smooth. There is no stopping and hanging midway to adjust. Hence, SpaceX has shown this can be done. I doubt it is the rocket issue but software confidence and practice. I suggest the scientist practice using a big drone. Create software for a drone carrying a heavy load landing after being dropped from great height. Drones are cheap and mistakes can be made. Learn the necessary sequence and understanding of how to land the dropping drones smoothly then borrow the concept to the rocket engine. It will be very different but at least from cheap drones you can fail multiple times.

等咗行者好耐呀, 又有佳作欣賞.
一如既往的精彩视频制作！👍👍👍
一如既往地精彩而无人出其右🎉🎉🎉 中国航天也终将有一天无国出我华夏之右🎉🎉🎉
要加油!
厉害
降落過程中，可否用降落傘的方式先大幅降低速度之後再開始噴火做最後的精確微調著陸作業（需先斷開降落傘並遠離降落傘），這樣應該可以減少燃料浪費，另外在噴火時的姿態也能維持在筆直狀態
如无必要，勿增实体，增加过多部件不仅增加后续维护难度，其实也会降低可靠性，算总账不一定合算。
不得不说，航天飞机即使现在看起来仍然很科幻。看上去比火箭垂直回收更科幻。

有理有据，不卑不亢，不像国内其他自媒体充斥无脑无逻辑的非吹即黑，果然军事科技类视频还是要看名校理工科学生
这样的返回式火箭很难说是什么理想的运载方式，毕竟要携带更多更重的燃料，火箭发动机推力和运载力有近一半被浪费了

始终不能理解，space X是怎么把航天飞机不能省的钱给省下来的。猎鹰是只回收第二级，不会收昂贵的第一级，而航天飞机是完全回收。猎鹰是耗费大量燃料回收，航天飞机是滑翔回收。猎鹰是用沉重的不锈钢，航天飞机是用高科技轻质材料。而航天飞机耗费最大的重新整修，space X根本不提。这钱怎么省的？
猎鹰回收第一级，不回收第二级，所以没有耗费很大的重新整修。
@@roywalker4K 那你怎么把钱省下来呢？你只回收了便宜的那一半吧。而且现在所有人都电视直播看到了，星舰首次试飞就有隔热瓦大量脱落，整修难度比航天飞机并无改进。他们没有足够说服力的理由。

这不把我们的机密泄露出去了吗
哥们你想多了
你是大傻子吗 这个孙子的东西全是抄了的和胡编乱造的 已经被把扒了底裤
能播放的都不是秘密了😂
这个家伙的视频全是错误 再国内已经被扒了裤子

派个中国人去spaceX插个U盘，然后就弯道超车了😂
对！就派你妈去！~
