这段时间里，美国总统换了两届，NASA负责人也因此轮换数任，SpaceX从野蛮人变成了行业灯塔，商业航天格局转变。而波音，人们更记得的是两架737 MAX飞机因软件问题坠毁，让其陷入深深的泥潭。波音在Starliner一步一步落后，是一场从指标、成本、内部体制的全方面落败。这个过程也构成了SpaceX故事的B面，让我们可以从...
NASA’s Space Launch System (SLS) is an advanced launch vehicle that is set to launch its Orion Crew and Service Module on missions to an asteroid and then eventually launching to Mars. The launch system is involved with NASA’s space exploration program. It costs over $2 billion annually ...
刚才已经把电动车掰开了揉碎了,发现电池组占成本的30%,这就是主成本(cost driver)。再把电池组掰开了揉碎了,寻找cost driver和reliability关系,这就是他们的知识产权IP,227美元/kWh VS 125美元/kWh,虽然知道他们的方法学,但是核心内容无从得知(欢迎爆料!) 他能把火箭掰开了揉碎了吗? 火箭掰开了就是发动机、结构...
Can NASA compete with the more cost-efficient SpaceX?Robert Block
steamrolled. When complete, the cost to launch Starship might be as little as $2 million. That would make SpaceX's constellation deployment vastly cheaper than any of the competition. Similarly, it can take large commercial payloads into space, possibly for much less cash than non-reusable ...
Reusable rocket and spacecraft technology is the backbone upon which SpaceX builds its cost estimates, which tend to be lower than those of its competitors. For example, the per-seat cost for SpaceX's Crew Dragon is around $55 million, NASA's Office of the Inspector General said in 2019...
SpaceX intends to launch at least four more test rockets in the coming months. The test flight takes SpaceX a step further towards demonstrating its rocket technology and the ability eventually to carry payloads weighing 150 tonnes into orbit. Nasa is also relying on Starship to land humans on...
《Reentry》尚未发行中译本,本文为第十章《The Cost of Mars》节选内容的试译。 SpaceX成立之初,马斯克就一直在谈论火星。 2002年,SpaceX现任总裁、COO格温·肖特维尔Gwynne Shotwell第一次与马斯克见面时,他热情洋溢讲述在这颗红色星球上定居的愿景。 肖特维尔说,他谈到火星,他的火星绿洲项目,他想做火星绿洲项目,...
Bill Whitaker: You do it again, and again, and again. Is that where the cost savings comes in? John Couluris: Exactly. We are now building with NASA, the infrastructure to ensure lunar permanency. Bill Whitaker: You have said that the Artemis program is the begi...
美国国家航空航天局NASA的阿波罗太空计划,需要40万人与全国预算的5%,一次只能让两人登上月球。 马斯克提出一个运输系统,他直到几年后,才确定星舰这个名称,一次可以将100人运往火星。 马斯克试图回答为什么要去火星,为什么SpaceX、为什么NASA、为什么人类,要投入时间、资金、辛勤劳动,来建造一支飞船舰队,并定居火星。
