Elon Musk: @Erdayastronaut @IzanRamos2002 @Caspar_Stanley 是的，推力增加了 20%，质量减少了 20%，但重点一直放在生产率和可靠性上。 质量、推力和 Isp 都会提高，生产率、可靠性和成本也会提高。 这是使生命多行星化并将意识扩展到虚空的唯一方法。

原推：@Erdayastronaut @IzanRamos2002 @Caspar_Stanley Yes, about 20% more thrust & 20% less mass, but focus has been heavily on production rate & reliability.

Mass, thrust & Isp will all improve, as will production rate, reliability & cost.

This is the only way to make life multi-planetary and extend consciousness into the void.
