**SpaceX Starship 试飞失败：过多燃料导致爆炸**
2023 年 12 月，SpaceX 的 Starship 星舰进行了第二次试飞。不幸的是，这次尝试以一次爆炸告终。经过调查，公司首席执行官埃隆·马斯克近日揭示了事故的真正原因。
马斯克表示，Starship 星舰在第二次试飞时装载了过多的燃料。具体来说，当第二级飞船成功地与第一级飞船热级分离后，由于液氧和甲烷被完全注入了 Starship 的第二级，飞行过程中不得不排出大量的氧气。这种氧气的过量排放最终导致了爆炸。
他还补充说，如果当时使用实际的有效载荷进行轨道运输，这次爆炸或许可以避免。这一事件再次提醒了航天界，每一次的试飞都需要对各种参数进行精确的计算和控制。
尽管遭遇了这次挫折，SpaceX 并没有停下脚步。据 IT之家报道，SpaceX 客户运营和集成副总裁杰西卡·詹森在 NASA 的电话会议上表示，公司已经在争取 Starship 的第三次试飞批准，并预计在 2 月获得批准。詹森还提到：“从硬件准备的角度来看，我们的目标是在一月份做好准备，然后从联邦航空管理局（FAA）许可的角度来看，我们将获得第三次飞行许可证”。
这次事件也为 SpaceX 提供了一个宝贵的学习机会，相信在未来的试飞中，公司会更加小心谨慎，确保每一次的飞行都能取得预期的成果。

News Content: **SpaceX Starship Test Flight Fails: Excess Fuel Leads to Explosion**
In December 2023, SpaceX’s Starship conducted its second test flight. Unfortunately, this attempt ended in an explosion. After investigation, CEO Elon Musk recently revealed the real cause of the accident.
Musk stated that the Starship was carrying too much fuel during its second test flight. Specifically, after the second stage successfully separated from the first stage at a thermal level, due to the complete injection of liquid oxygen and methane into the second stage of Starship, a large amount of oxygen had to be discharged during the flight. This excessive discharge of oxygen ultimately led to the explosion.
He added that if an actual payload had been used for orbital transportation at that time, this explosion might have been avoided. This incident once again reminded the aerospace industry that every test flight requires precise calculation and control of various parameters.
Despite this setback, SpaceX has not stopped moving forward. According to IT House, SpaceX Vice President of Customer Operations and Integration Jessica Jensen said during a NASA conference call that the company is already seeking approval for Starship’s third test flight and expects to receive approval in February. Jensen also mentioned: “From a hardware preparation perspective, our goal is to be ready by January, and from an FAA permit perspective, we will obtain a third flight license.”
This event also provided SpaceX with a valuable learning opportunity. It is believed that in future flights, the company will be more cautious and ensure that each flight achieves the desired results.”
