郭德纲的话，遇见了未来小行星带之间航行时的燃烧方式，
小行星上一个人影都没有，根本没有补充化学燃料的机会，那时候飞船抓住什么石头都要送到核聚变发动机里，变成高速粒子喷出去，获得前进动力，能抓住无烟煤就更好了
核聚变堆本身不输出大量物质，无法做推进发动机，但是可以加热其他物质

【 在 tgfbeta 的大作中提到: 】
: 郭德纲：“比如我和火箭专家说，你那火箭不行，燃料不好，我认为得烧柴，最好是烧煤，煤还得精选煤，水洗煤不行。如果那科学家拿正眼看我一眼，那他就输了”。

There are two main reasons why the Apollo reentry capsule appeared less black than the Soyuz capsule after landing:

Heat Shield Material: Both capsules relied on heat shields to absorb the tremendous heat generated during atmospheric reentry. However, they used different materials:

Apollo: Used an ablative heat shield made of a resinous material filled with millions of tiny fiberglass spheres. This material burned away during reentry, leaving a lighter brown or tan colored char on the surface.
Soyuz: Employed a heat shield made of phenolic impregnated fabric. This material charred black due to the extreme heat, giving it a darker appearance after landing.

Reentry Profile: The reentry profiles of the two capsules differed slightly.

Apollo: Followed a lifting reentry, which provided some aerodynamic lift and allowed for more control of the landing zone. This shallower reentry resulted in a bit less heating on the heat shield compared to the Soyuz.
While both capsules endured scorching temperatures during reentry, the material composition and reentry profiles led to the Apollo capsule appearing less charred and black than the Soyuz upon landing.
