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The Mun的旅行, 如果你还没有的话我建议你看看这篇check out the tutorial.

介绍

登陆Minmu类似于登陆Mun,除了少数例外:

  1. 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.
  2. 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Reaction Control System就能将倾倒的小型飞船纠正过来.
  3. 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).
  4. 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.

Constructing a Minmus Rocket

*The Upper Stage (Lander)

This stage should be much lighter than the one you would use to reach The Mun. Landing on Minmus and returning to Kerbin only requires about as much fuel put together as the landing phase of a Mun visit.

*The Middle Stage (Transfer Burn)

Take advantage of the weight you have saved on your lander to pack more fuel for this one. You will need it for the trip between Kerbin and Minmus.

*The Lower Stage (Launch)

This stage should not be much different than the one you would use on a Mun attempt. If you are not feeling confident about your middle stage, it never hurts to pack a little more fuel/thrust.

Launching Into Kerbin's Orbit

Same as any standard launch, presumably on a much larger scale. Read the tutorial for how to reach orbit if you haven't already figured it out.

Minmus Injection

Similar to the Mun guide, wait until Minmus is about 4-5 degrees over the horizon (20-40 degrees in the map) to begin your burn. It will appear as a small dot above the horizon. Burn until your apoapsis intersects Minmus' orbit, and (hopefully) you will be caught.

Landing on 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.
