Tutorial:How to get to Minmus/zh-cn
这个教程会尝试教你如何到达Minmus.假设你已经成功完成了到Mun的旅行, 如果你还没有的话我建议你先看看这篇登陆Mun.

介绍
登陆Minmu类似于登陆Mun,除了少数例外:
- Minmus比Mun距离Kerbin更远 ,这意味着:
- 从Kerbin到Minmus轨道的旅行你需要更多的燃料.
- 它的轨道更慢,使得捕获速度更低.
- Minmus比Mun小得多,这意味着:
- 由于更低的重力,登陆Minmus和从Minmus入轨更加简单,需要的燃料也更少.
- 它的引力范围(SOI)更小,需要更精确的操作.
- 它的重力如此之低以至于只用姿态控制火箭就能将倾倒的小型飞船纠正过来.
- Minmus拥有轨道倾角,这意味着:
- 直接飞向Minmus会有更高的机会失败.
- 匹配轨道需要一点调整倾角的知识(和额外的燃料).
- Minmus并不被Kerbin潮汐锁定,这意味着.
- 如果直接飞向Minmus,尝试登陆选定的区域时需要更精确的操作.
搭建一个Minmus火箭
*上层(登陆舱)
这一层应当比你之前用于到达Mun的还要轻得多.登陆Minmus并且返回Kerbin的燃料加起来也只需要大约单程访问Mun的那么多.
*中层(推进舱)
你在登陆仓所省下的重量都在这一层装成燃料吧,你在从Kerbin飞往Minmus的旅途中会用到它们的.
*底层(发射)
这一层应该和用于Mun的差不多.如果你对于你的中层不那么自信的话,多来点燃料/推进器也没什么坏处.
发射到Kerbin轨道
与标准发射相同,也许尺度更大一点.如果搞不明白的话建议你看看教程:如何入轨.
靠近Minmus
类似于Mun的方法,等到Minmus超出地平线4-5度时(在地图上20-40度)开始推进.在地平线上方会出现一个小点.持续推进直到你的远地点与Minmus轨道相交 ,这时你就有希望被Minmus捕获.
登陆Minmus
Your orbit, retrograde burn, and landing will all be at much lower speeds than they would be at either the Mun or Kerbin. In fact, it's unlikely that you will (or should) reach speeds above 100m/s at any point near Minmus. Try aiming for a frozen lake if you are looking for an easier landing, close to chart datum. Minmus' large mountain ranges make for more of a challenge elsewhere on the surface.
Returning to Kerbin
Basic method
This is a crude but effective method, using slightly more fuel than the advanced method below. Begin a light burn until you escape Minmus' SOI, then apply retrograde thrust until your periapsis is below 65km altitude on Kerbin. Happy Landings!
Advanced method
This method is cheaper on fuel.
- Burn to raise the apoapsis to around 10,000m.
- Burn prograde at apoapsis to achieve a low equatorial orbit.
- When the craft is moving retrograde relative to the moon's orbit around Kerbin, face prograde and burn again to escape velocity.
- Keep burning until your periapsis around Kerbin is below 32,000m.
- You will now be on a trajectory towards Kerbin. You will not need to burn again to re-enter the planet's atmosphere.
