Minmus/Data

MinmusはKerbinの衛星のうち小さい方である。 KerbinあるいはMunの地表からは1～2ピクセルほどの藍色の点として観測でき、わずかだが上下に揺れ動いているように見える。接近すると凍ったビュート、広大な丘、凍った湖を連想させる地形を持った黄味がかった白い天体であることがわかる。高高度地帯は5.7 kmを超える高度を持つ。Minmus軌道に乗るにはMun軌道よりもう少々高いdelta-vが必要である。しかし離着陸や帰還にはMunよりも少ないdelta-vで済む。

tutorialにてMinmusへの往き方帰り方が解説されている。

ゲーム内の紹介

Orbital characteristics

Minmus orbits Kerbin at a continuous altitude of 46,400,000 meters and takes approximately 920 m/s Δv to transfer to from low Kerbin orbit. The synodic period from Kerbin's surface is 14 days, 3 hours and 1 second (1,220,401 seconds). A synchronous orbit around Minmus is possible at an altitude of 357.94 km.

It is important to be careful when attempting to return to Kerbin from Minmus, as Minmus' high orbit makes it very easy to escape Kerbin's sphere of influence entirely. However, this means that a base on or in orbit around Minmus would make a convenient refueling station for vessels leaving the Kerbin system.

Surface Temperature

Calculation of the expected surface temperature for Minmus, using received energy from Kerbol, with the Stefan-Boltzmann Law for the radiated power gives a temperature of -50 degrees Celsius. Whilst this is lower than the measured value, it lends support to the theory that Minmus is a captured comet. It could not have formed at its present location but has an albedo high enough to prevent catastrophic sublimation of its icy composition. A high salt content, if present, would also slow the sublimation process.

This value of temperature was calculated using: An emissivity of 0.9 (close to but lower than compacted ice), an albedo of 0.6 (close to but lower than the real ice moon Europa), and the luminosity of 3 yotta watts for Kerbol. If the same calculation is performed for Kerbin with typical Earth values of emissivity and albedo, a temperature of positive 15 degrees Celsius is obtained.

Topography

Minmus has very divergent elevations. Plateaus at around 5 km high are matched by "Flats" at datum altitude (0 m). Much of the surface is transitional lowlands and highlands. With バージョン 0.23, there are now 9 biomes.

The various "Flats" are almost perfectly flat and believed to have once been the site of liquid lakes. Minmus also has some mesas, one of which is near Minmus's north pole, that are so high compared to Minmus' sphere of influence that they count as "in orbit" according to the navigation tools. Unless the player manually switches the navball to Surface mode, this makes landing on these plateaus challenging, as the direction marker and speed will not automatically correct for the rotation of the surface.

For most landings which are not on a plateau or in a lake, the touchdown altitude is usually between 2000 m and 2500 m.

Jumping on this moon will make the kerbonaut ascend 10 m from the ground.

Taking a Surface Sample from Minmus says that it is a "crystalline substance, definitely not edible".

バイオーム

Minmusのバイオーム分布図

Minmusには多様なバイオームが分布しており、それぞれ別の実験結果を得ることができる。:

サイエンス

Minmusのサイエンスポイント乗数は地表上空いずれも他の天体に比べ、かなり低い(Munよりはいくらか高い)設定になっている。しかしMinmus到達は比較的容易であり、多数のバイオームはそれぞれ別のサイエンスポイントを得ることができる。そのためゲーム中盤ではMunと並び重要なポイント獲得源となる。

Trivia

• The name "Minmus" may be derived from the Latin word “minimus”, which denotes the smallest member of a group of beings or creatures, and is also the medical name for the smallest digit on the hand or foot. Minmus is the smallest member of the Kerbin system.
• It's also possible that Minmus is named after Saturn's moon Mimas.
• It is possible to deorbit, land and ascend back into orbit around Minmus with the EVA jetpack starting at 100% fuel.
• If 2HOT Thermometer is used on surface, it shows a temperature of -0.007, which is just enough for water to freeze.
• If SC-9001 Science Jr. is used near or on Minmus in career mode, it will state that its test samples start to glow due to radiation. This might cause Minmus to have a higher temperature than Mun.
• Most, if not all, crew reports and EVA reports along with other experiments, may mention something about Minmus looking like a minty dessert. This may be a reference to the colour “Magic Mint” made by the Crayola company in 1990, and the colour itself looks almost exactly like that of Minmus's surface. This relation may be intentional; however, it may just be a coincidence.
