so u dont need the booster if u have a lower gravity wells , so no booster is needed on the moon or Mars or any other moons of Jupoter or Pluto .
U just need the space ship.
The booster is just there for heavy gravity wells.
And then we've also been able to optimize the propellant needed for boost-back and landing ,to get it down to about seven percent of the liftoff propellant load ,and i think with some optimization we can get down to about six percent.
And we're also getting quite comfortble with the accuracy? of the landing.
And if u've been watching the Falcon 9 landing ,u'll see that they're getting increasing closer to the bullseye.
And we think ,particular with the addition of some thrusters ,maneuvering thrusters ,we can actually put the rooster right back on the launch stand.
And then those pins at the base are essentially centering features to take out any minor position mismatch at the launch site.
So this is what it looks like at the base .
So we think we only need to gimbal or steer the central cluster of engines .
so u dont need the booster if u have a lower gravity wells , so no booster is needed on the moon or Mars or any other moons of Jupoter or Pluto .
所以在引力比較小的時候不需要使用助推器 秦爆，所以在火星的衛(wèi)星上或木星以及冥王星的衛(wèi)星上時不需要使用推進(jìn)器 。
U just need the space ship.
你只需要太空飛船 憔披。
The booster is just there for heavy gravity wells.
推進(jìn)器只在引力比較大的時候使用 等限。
And then we've also been able to optimize the propellant needed for boost-back and landing ,to get it down to about seven percent of the liftoff propellant load ,and i think with some optimization we can get down to about six percent.
我們也同樣會對推進(jìn)劑進(jìn)行優(yōu)化 以被需要完成一級火箭的回收降落 。
我們也會對推進(jìn)劑進(jìn)行優(yōu)化以完成一級火箭的回收降落 活逆，
我們也會對推進(jìn)劑進(jìn)行優(yōu)化來供給一級火箭回收降落所需 精刷，減少7%的發(fā)射推進(jìn)劑載荷，
我認(rèn)為通過一些優(yōu)化可以再減少6%的燃料 蔗候。
And we're also getting quite comfortble with the accuracy? of the landing. 精準(zhǔn)降落這一點(diǎn)我們也確實(shí)做得非常平穩(wěn) 怒允。
And if u've been watching the Falcon 9 landing ,u'll see that they're getting increasing closer to the bullseye.如果你觀看了獵鷹9號的著陸， 你會發(fā)現(xiàn)他們明顯更接近了圓心點(diǎn)
And we think ,particular with the addition of some thrusters ,maneuvering thrusters ,we can actually put the rooster right back on the launch stand.
我們認(rèn)為 锈遥， 增加推進(jìn)器的這一特點(diǎn) 纫事， 通過操控推進(jìn)器 ， 我們確實(shí)可以讓火箭正確地返回到發(fā)射臺 所灸。
And then those pins at the base are essentially centering features to take out any minor position mismatch at the launch site.
這些底部小孔居中的這一特征 丽惶，用以解決發(fā)射場微小位置不匹配的問題 。
而那幾個中間的小孔 爬立， 用以降落時進(jìn)行距離微調(diào) 钾唬。?
So this is what it looks like at the base .
所以這就是為什么底部設(shè)計(jì)成這個樣子 。
So we think we only need to gimbal or steer the central cluster of engines .
我們我們認(rèn)為我們只需去控制引擎中間的部分 侠驯。
