Estelar the Powerful

Estelar "the Powerful" Baxtor, ruler of the Navus plains, and Champion of The Northerlands was a human male from somewhere in the north (where modern day Ber'dun is located). He was one of the legendary *Three Saviors.*

Estelar is known for his work during the *Last Battle* where he openly challenged the archdevil Levistus as well as the *Battle for Nir Lodar* where he slew the archdevil's next in command: the general of death. He is the only one of the Three Saviors who survived the Era of Torment. For recognition, he was awarded the title "Champion of The Northerlands", he was given his pick of any bride (he chose the princess of Thavia), and he was given all the lands encompassing the Navus plains. His descendants would go on to form the Holy Kingdom of Ber'dun.

He is claimed to be one of the greatest warriors in the history of the realm. His weapon of choice was the glaive.
Adapter

***This page has been archived and locked for editing!***

 **This feature has been removed from the game, and you may no longer edit this page.**

**This part is not in the game**
This part was removed in a recent update, and is no longer in the game.

The **adapter** is an obsolete part. It has a trapezoid shape. The original purpose is to connect Small Fuel Tanks to Large Fuel Tanks. Adapters weren't required to connect them, but reduced aerodynamic drag.

The adapter was removed from SFS in version 1.4, which instead made fuel tanks automatically adapt to a slightly wider or thinner width fuel tank. Here is a list of fuel tanks that can adapt to one another.

* 4 wide from 4 to 8 wide
* 6 wide from 4 to 10 wide
* 8 wide from 4 to 12 wide
* 10 wide from 6 to 12 wide
* 12 wide from 8 to 12 wide

Parachute bases are 1.6 squares wide, but fuel tanks adapt to them as if they're 4. Tanks can be made effectively 1.6-wide by putting parachutes on both ends, and docking ports part-clipped inside the tanks can allow them to be detached.

Fuel tanks adapt to separators they're adjacent to, if their centers are aligned, as if the separator is a fuel tank, but separators create fairings to center-aligned fuel tanks above them (or otherwise in the direction they're pointing in) with gaps between them, according to the table listed in Separator.

## Trivia

* Before version 1.35, the adapter could not transfer or hold any fuel, effectively separating the fuel tanks adjacent to it.
All parts with significant amounts of drag.

**All Parts with high amounts of drag in version 1.5 below.**

Very Significant amounts of drag:

* Separator
* Aerodynamic fuselage

Significant amounts of drag:

* Rover wheels
* RCS thrusters
* All Engines except atmospheric engines at the time like Titan and Hawk Engine because it has weaker drag.

Stronger than usual drag:

* Solar panels
* Structural parts: Note that covering it works for some reason

Feast of the Moon

The **Feast of the Moon**, or **Moonfest**, is an annual festival in the Calendar of Harptos, occurring between the final night of November and the first day of December. It is the last great festival of the calendar year.

The day traditionally marks the onset of winter. It is also a time to celebrate and honor the ancestors and the respected dead. On this day, folk bless their ancestors' graves and perform the Ritual of Remembrance. People also gather to tell stories of the deeds of their ancestors and of the gods until deep into the night. This is a time to hear of past heroes, great treasures, and lost cities.

Heralds have a number of special duties on the Feast of the Moon. Prime among these is to perform the Bloodsong Ceremony, at which a Herald publicly recites the genealogies of each noble family in the area. In this way, the Heralds reaffirmed a noble family's traditional authority and status, as well as the respect accorded to them.

Priests of a number of deities of various pantheons hold rites, ceremonies, and festivals on the Feast of the Moon. Many, though not all, focus on remembering the dead in one way or another.

## On This Day

* Priests of N'asr tell the Deeds of the Dead to preserve their memory.
* Worshipers of Lliira open a holy festival with the Swords Cast Down ritual in which weapons are thrown on the ground with chanting and covered with fresh flowers.
* Worshipers of Lurue observe a quiet ceremony ushering in winter and remembering the dead. It is the anniversary of the founding of Silverymoon and is celebrated by the unveiling of works of art and song.
* Worshipers of Savras call this day the Vision and spend 24 hours meditating in a steam bath or a haze of incense.
* Worshipers of Shar call this day the Rising of the Dark and plot their nefarious deeds for the next year after a live sacrifice.
* Worshipers of Shiallia invite friendly creatures to join in feasting, dancing, and singing.
* Worshipers of Talos call for storms and lightning.
* Worshipers of Tempus honor the dead.
Orbiter

*Main article: [[]]*

An **orbiter** is a spaceship designed to orbit a celestial body. Orbiters are usually not designed to land. However, it may carry a lander for lander missions. An orbiter can be manned or unmanned.

## History

The history of space exploration gives many well known examples. May we remember here only a few: MESSENGER (for Mercury), Venus Express, Mariner probes, Galileo and Cassini. Also, during the Apollo program, there were used manned orbiters that orbited the moon (the Service and Command Module and the lunar lander).

## Gameplay

Orbiters can be used for multiple functions:

* Conducting research (not yet in-game).
* Helping Vehicles.
* As building blocks for a Space Station.
* Artificial Satellites (also purely aesthetic for now).
* Telescopes
* Discoveries
Capsule

* 1.5.9
* 1.5.3
* 1.5.1.3
* 1.4
* 1.0

A **Capsule** is a part that can allow control over a rocket. It has good aerodynamics and is currently only available in a small size. This capsule can carry one astronaut.

## Trivia

* The capsule was the first part added to the game along with Separators, Hawk Engine, Valiant Engine, Fuel Tank, and a few more.
* It is likely inspired by the capsule used in NASA's Mercury, Gemini and Freedom missions and the Mk1 Command Pod in KSP. In real life, the capsule does not have a reaction wheel to produce torque. The astronauts could have spun around inside it, but it would likely have produced less than a specialized reaction wheel (depending on power).
* The lowest layer of tiles now has attachment points on the side, unlike the other three layers.
* The Capsule's description says that it holds one astronaut. In real life, similar ones can hold 4, 7, or even 13 astronauts at once. However this could change as a part of the Astronauts update, which as of right now has not released and has no set release date.
* The top of the Capsule is designed to join to the 2×1 docking port and parachute without overhangs, for optimal aerodynamics.
* Within the files the capsule with the heat shield is referred to as `CapsuleNew` while the capsule with no heat shield is referred to as just `Capsule`. The version with the heat shield is useful for the career mode in case you don't buy a heat shield.
* A capsule with a top parachute on it is called a **Capsule + Parachute.**
* You can customize your capsule's skin by putting a 10t fuel tank on it, and putting it with a parachute on top. It can also be put with RCS Thrusters, so you can control your capsule's trajectory.
* It used to have an metal ring at the tip of the capsule.

## History

* Prior to 1.4, the Capsule had what looked like an ablative heat shield on its bottom, and when the part was re-textured in 1.5.1.3, the heat shield was added back, but brighter than the original. In 1.5.3, the heat shield separated from the capsule and became its own part.
* In older versions of the game, the capsule used to be 4 blocks tall. On 1.35 it was 5 blocks tall, on 1.5 it returned to 4 blocks tall, at 1.5.1.3, it was 4 1/2 blocks tall, and on 1.5.3 it returned to 4 blocks tall.
* On 1.35, the part was renamed the "Command Module", but in a later version (1.5) it was renamed back to "Capsule".
* On 1.5.9, the Capsule's texture has been significantly changed, and now what appears to be a door has been added.
Later use stages.

**Work in progress**

This page is a work in progress, and some information is currently not present.
You can contribute by expanding it.

This is a kind of Multistage rocket that uses stages that are designed to stay in orbit for later use.

There are new rockets with designs like this other than some rockets shown in the ROL Challenge despite SFS having a larger community and the fact that Docking Ports a part needed for this kind of stage is now fully accessible nowadays

## History

The first SFS Stage designs like this date all the way back to July 18, 2018, which are mainly caused by the ROL challenge.

Ariel

**Upcoming**
This part or feature is not in the game, but could be added in a future update, version 1.8.**Planets Expansion Required**

*Some or all of the features on this page requires the **Planets Expansion** in-app purchase.*

**Ariel** is the 2nd closest moon to Uranus and is reddish-brown in color.

## Ariel

* Physics View
* Map View

## Surface Features and Terrain

The observed surface of Ariel can be divided into three terrain types: cratered terrain, ridged terrain, and plains. The main surface features are impact craters, canyons, fault scarps, ridges, and troughs.

Ariel's terrain if rough and jagged, in addition to that its surface is moderately red, signifying that Ariel's surface may be one of the oldest in the Uranian system. Ariel is saturated with canyons and craters, further adding to its hypothesized age. Driving rovers or landing landers on certain areas of Ariel could be difficult, as the steep terrain may cause a lander to tip, causing severe damage, and the inability to re right without RCS.
Maxwell Montes

**Maxwell Montes** is the largest mountain in the Maxwell Montes range on Venus. It is located near the north pole of Venus.

Due to its steepness, it is recommended to land on the parts of the mountain that are not that steep as the other regions or at at sides of the mountain.

Landers may land on top of it to avoid the effects of Venus's atmosphere.
High Harvest

**High Harvest** is an annual festival in the Calendar of Harptos, taking place between September 30th and October 1st. It is traditionally a feast to celebrate the harvest and the abundance of food, but also the time when those wishing to travel leave on their journeys before winter sets in.

Preparations for the feast start as early as a tenday before, while preparing, cooking, and preserving the harvest for the cold winter months. Traditions vary from community to community, but examples of festive activity include food-related contests; races and challenges of skill and strength; receiving homemade sweets from the local clergy; and priests blessing larders, wine cellars, grain bins, and food preserves.

This day is an important anniversary to various governments. Often, taxes and tithes came due, rulers hold "open courts" to hear the concerns of their citizens, oaths are publicly renewed, troops receive marching orders to new duty stations, and guilds meet to confer on prices and rate changes for goods and services.

Tavern jests say dwarves only drink water and elves drink only dew on this day. However, these traditions are completely false.

Legends claim that children born on this day are favored by Tymora to have lifelong good luck, but smitten with wanderlust.

Another legend says that females born on this day have control over their reproductive system (*i.e.*, get pregnant only when they want to) by force of will alone, and that they could instantly sense when they have been poisoned, either by ingestion or bitten by a venomous creature for example.

## On This Day

* Worshipers of Lliira open a holy festival with the Swords Cast Down ritual in which weapons are thrown on the ground with chanting and covered with fresh flowers.
* Worshipers of Loviatar celebrate the Rite of Pain and Purity by dancing in a circle upon broken glass or other sharp objects.
* Worshipers of Malar celebrate the Feast of the Stags and pledge to hunt through the winter for selected people unable to hunt for themselves.
* Worshipers of Shiallia celebrate fruition on this day, inviting friendly creatures to join in feasting, dancing, and singing.
* Worshipers of Silvanus consider Highharvestide holy, and often give sacrifice by breaking and burying an object constructed of wood.
* Worshipers of Talos call for storms and lightning.
Eris

**Upcoming**
This part or feature is not in the game, but could be added in a future update, version 1.8.**Planets Expansion Required**

*Some or all of the features on this page requires the **Planets Expansion** in-app purchase.*

Eris is a trans-Neptunian dwarf planet located in the scattered disc. It may be added in the 1.8 update.

## Eris

* Physics View
* Map View

## Overview

Eris is a small dwarf planet located in the scattered disc, within the outer solar system. It has a very eccentric orbit around the sun, its perihelion is 38 AU while its aphelion is 93 AU. Because of its extreme orbit, its orbital period is 559 earth years. Eris was discovered on January 5, 2005 by Mike Brown, Chad Trujillo, and David Rabinowitz. Eris is strange because it is 75% the size of Pluto by 17% more massive than Pluto, this prompted the IAU to define the term "planet" and thus Pluto, Ceres, and Eris became dwarf planets.

## Physical Features and Terrain

Eris is thought to have a thin coating of volatiles (frozen methane, water, ammonia, CO2, etc.) and a surface peppered with many craters. Eris is smaller than Pluto but it is 17% more massive than Pluto, most likely meaning that it has a large metal core. Because of its distance from the Sun its average surface temperature is 30-56 K (−243.2 to −217.2 °C; −405.7 to −358.9 °F). Not much else is known about Eris. Eris has a relatively low surface gravity of 0.82 m/s² and a reasonable low orbital velocity, so landing and orbit insertion are not very expensive.

### Atmosphere

Eris most likely has a transient atmosphere, meaning the volatiles melt and sublime during the day, and freeze back onto the surface during night. The atmosphere would be very thin so parachutes would be useless and heat shields would be unnecessary. Retrorockets would be better for landing. The atmosphere is most likely comprised of methane, ammonia, water, CO2 along with other compounds.

## Satellite

Eris has one natural satellite, named Dysnomia. Dysnomia is very small, having an average diameter of 600 km. It is quite dark compared to its parent. It has been theorized that Dysnomia once had a shiny icy coating like Eris, but the Sun melted and subsequently dissipated due to its low gravity, leaving the moon with only its coal-black rocky surface, very much like S/2015 (135472) 1. Not much else is known about Dysnomia.
Shieldmeet

**Shieldmeet** is the equivalent of a leap year day in the Calendar of Harptos, occurring once every four years, adding a day after the festival of Midsummer and before August 1st. Traditionally the day was used for fairs, bazaars, musical and theatrical performances, and tournaments of skill and magical ability. Nobles usually held court to hear the petitions of their people and to make or renew trade pacts, alliances, and agreements.

## On This Day

* Worshipers of Beshaba continue reveling in rudeness and destruction.
* Worshipers of Deneir observe the Gilding in which priests take turns casting a spell to emboss in gold a single letter of the Words of Deneir onto a manuscript for public viewing.
* Priests of N'asr tell the Deeds of the Dead to preserve their memory.
* Mielikki's Wild Ride continues.
* Worshipers of Selûne perform the Conjuring of the Second Moon ritual, with simultaneous chanting at all her temples in Faerûn. This summons the Shards to assist the earthly clergy.
* Worshipers of Torm celebrate Shieldmeet very seriously as a time of agreements, compacts, and oaths.
"Single 2" Engine

Building Moon Rockets

**Moon rockets** are rockets that are designed to visit the Moon, Earth's only natural satellite. These rockets do not need to be as large and sophisticated as those designed to reach Mars or Jupiter due to the low Delta-V required (670 m/s, from orbit). It is recommended that players build Moon rockets after orbital rockets before advancing.

# Stages

Building a Moon rocket is quite simple compared to building longer-range rockets. A Moon rocket should consist of at least 3 stages:

## Stage one

This stage will, or should carry the rocket to closely achieve orbit around Earth.

It should contain at least 1 high-thrust engine (Hawk Engine, Titan Engine or Frontier engine). Have some fuel tanks, but not too much (6 wide or more is recommended). It is also viable, and advised to add a pair of boosters that run out of fuel first to be staged with side separators (see figure 2). The boosters can be ignited before the first stage fires its engine(s) to get to orbit.

## Stage two

The second stage will get the rocket into a parking orbit, shoot the rocket into a trans-lunar injection and optionally put the rocket into a lunar orbit.

It should be propelled by a vacuum engine, like the Valiant Engine or Frontier Engine.

## Stage three

The third stage will (or should) be able to land on the moon, and if manned, return to Earth. It should usually be propelled by a small engine like the Kolibri Engine. Add a pair of landing legs to cushion the impact while landing on the Moon, in case you don't perform a landing burn early enough. If it can get back to Earth, it should have a capsule (that can carry astronauts), parachutes (to slow down into the atmosphere during landing on Earth), and a heat shield to protect it against the reentry heat.

## Other stages

It can have up to 5 stages, or several modules, for more sophisticated missions, such as an Apollo 11 recreation.

## Real Moon rockets

Rockets that have gone to the Moon in real life. The most famous example is the Saturn V. There are even rockets that were intended to be launched ON the Moon's surface.

Neptune

**Upcoming**
This part or feature is not in the game, but could be added in a future update, version 1.8.**Planets Expansion Required**

*Some or all of the features on this page requires the **Planets Expansion** in-app purchase.*

## Neptune

* Physics View
* Map View
* Inner System
* Outer System

## Orbit Data

### SOI radius

~30,000 kilometers(?)

****Neptune**** is one of the four gas giants in SFS. It might be added in SFS 1.8.

## Overview

Neptune is the farthest gas giant from the Sun. Neptune has many moons including Triton and Nereid. Like all other gas giants, Neptune has a ring system, though it is not very large and is very dark. The planet's most striking feature is it's dark blue hue, theorized to come from high levels of methane in the upper atmosphere.

## Terrain

Since Neptune is an ice giant, it inevitably has no terrain. In addition to this, it also means you cannot land on it, and will sink into the core if attempted.

## Atmosphere

Once added to the game, it is theorized that it will be 50 kilometers in height, similarly to Uranus. Although not very high in terms of height (assuming Venus’ is 40 kilometers), it’s accurate considering it’s smaller and less massive than the gas giants. Due to it containing methane, it will have a dark blue tint compared to the other gas planets. Due to the atmosphere's density and thickness it can be assumed that reentry would be quite difficult, even with a heat shield.

## Satellites

Neptune has 14 natural satellites, the largest of which is Triton. The following is a table describing all of these satellites.

Moons of Mars

## What to do on Neptune?

Many things can be done on Neptune and its moons.

### Gravity Assist

Neptune has a reasonably high gravity (and hill sphere), making the planet helpful for reaching distant Kuiper Belt Objects, or going interstellar.

### Orbital Probes

Probes can be placed in orbit around Neptune and Triton, but orbit insertion around the small irregular ones may be challenging or downright dangerous.

#### Atmospheric Probes

Atmospheric probes could be sent in to study Neptune's atmosphere, but they would require intense thermal and pressure shielding to withstand the intense conditions within the thick atmosphere. *Inspired by the Galileo Atmospheric probe.*

### Grand Tours

A grand tour of the solar system is possible with Neptune.

### Much More!

Neptune has endless possibility for exploration, everything from sample return missions to space stations and surface bases on moons are all possible, but only with lots of delta-v and perseverance.

## Trivia

* Neptune's moon Neso has the longest orbital period of any moon in the solar system; having and orbital period of nearly 26 earth years.
* Neptune is the smallest gas giant.
* Neptune was the only planet discovered using math.
* Neptune has rings, though they are very faint.
Dione

**Upcoming**
This part or feature is not in the game, but could be added in a future update, version 1.8.**Planets Expansion Required**

*Some or all of the features on this page requires the **Planets Expansion** in-app purchase.*

Dione is a large spherical moon of Saturn.

## Dione

* Physics View
* Map View

## Terrain

### Ice Cliffs

Dione has unique "wispy terrain" looking like white swirls on the surface.

### Craters

Craters on Dione are very numerous. Unlike the craters on the Moon or Mercury, Dione's craters lack the high-relief features.

## Atmosphere

Dione's atmosphere is very thin, primarily made up of molecular oxygen and water.

Parachutes would be useless, due to the atmosphere's nature of being thin.

Heat Shields would have no purpose and would be dead weight.

Aerobraking and aerocapture would not work because the atmosphere would is so thin.
Earth Activities

Spaceflight Simulator is not limited to space and other planets, and activities can occur on Earth as well. This page lists some possible activities on Earth.

## Launchpad Activities

*Main article: [[]]*

On the launchpad, it is possible to build artificial structure using fuel tanks and structural parts. Examples include launch towers, and a launch complex. It should be moved if the structure is within the hitbox of the launchpad; if not, it is automatically removed upon the launch of a rocket.

## Activities

There are so many activities that you can do on Earth. Here's a list of them:

### Rovers

*See also:*
Rovers are unmanned vehicles with wheels that can move freely along the lateral axis of the surface. They require a controlling module (usually a probe), rover wheels, and a source of electricity (either by batteries or by RTG or the solar panel (either small or large).

There are many activities related to rovers, such as

* Breaking ground speed records
* Building real-life vehicles into the game (like cars)

### Testing

The Earth provides an excellent location for testing upcoming technologies because it is easily accessible. Players can test, optimize and perfect many systems before it goes live on other planets.

Examples include:

* Testing custom-built landing legs
* Testing custom launch escape system
* Testing rockets before main launch

### Having War

You can start entire wars with slide seperators on the side of your rocket. These aren’t really efficient, but certainly fun. One can spend up to hours fighting with slide seperators and wreck rockets.
Mare Tranquillitatis

**The Sea of Tranquility** is a lunar landmark. It is based off of the real lunar feature and is a flat place on the moon.

## Terrain

The Sea of Tranquility is a flat place on the moon with a few craters and some hills. The landmark is relatively large in size, making it a landing site for some spacecrafts.

In this landmark, landing on a crater or any rough terrain is safe because of its small size.

## Gallery

## Trivia

* This happened to be the landing site of the Apollo 11 mission and the *Surveyor 5* lander, and the crash site of the *Ranger 8* probe.
* In real life, it is a lunar *mare* or sea that is located at the near side of the moon.
* The material on the location mainly consists of basalt that formed around 3.8 billion years ago.
* The mare is slightly bluish in color.
Fuel Pipe

## Fuel Pipe

### Mass (t)

—

**Fuel Pipes** will be used for automatic fuel transfer.

For a moment pretty much nothing is known about them, with an exception of their appearance in translation files and a concept posted on official

Spaceflight Simulator Discord.
Earth Atmospheric Activities

Before sending a rocket into space, most space agencies around the world first tested their technologies on Earth without leaving the atmosphere.

## Tests

These should be the first things one would try before going into space. Atmospheric experiments can be done with very small rockets, which are not designed to reach outer space. These tests will give answers to questions like:

* How much weight can an engine handle?
* How will a certain design affect the aerodynamics of a rocket?
* How and when to deploy parachutes?
* How long will a fuel tank last?
* How far can a rocket travel through the atmosphere?

## Short ballistic missiles

The simulator allows anyone to test the efficiency of short range ballistic missiles, which do not exit the atmosphere. They can also send other science equipment to study the atmosphere of Earth.
Captured Asteroid

* System
* Physics View
* Map View

The **Captured Asteroid** is a small, unnamed asteroid that orbits **Earth**. It is 200 meters in diameter and was added in the 1.5.10 update. Compared to everything else, it has the weakest gravity in Spaceflight Simulator.

## Orbit

The Captured Asteroid has an orbit around Earth at an average distance of 37,200 kilometers, which is around two times the average distance between the Earth and the Moon. It orbits the Earth every 16 days and 13 hours with a fairly high eccentricity of 0.37; because of this, its perigee of 23,436 kilometers brings it close to the moon's orbit, and its apogee of 50,964 kilometers is around halfway between Earth and the edge of its sphere of influence.

## Terrain

Its terrain is very similar to that of Phobos, but its terrain is more jagged than that of Phobos, which is one of the two moons of Mars. Its surface appears to be made of silicate rock, as it has a gray surface. The surface has small, sharp, grey rocks on the surface.

### Moving on the asteroid

Driving a rover on the asteroid is difficult because the rocket will probably escape its gravity and orbit Earth instead.

* A solution is to use ion engines or RCS thrusters and turn on the Infinite Fuel cheat on the rover to keep it on the surface.
* The second solution if you do not have the Part Expansion Pack, is by using rotation, since like Phobos and Deimos, the gravity here is also too weak to hold rotations.
* It is also possible for someone to use an RCS powered probe to hover around and land on the moon. Be sure to slow down on time, or risk escaping the SOI

## Part Behavior Demonstrations

Due to the near-zero gravity of the captured asteroid, it is possible to demonstrate the magnetic forces of docking ports from there easily. If you undock from the ladder, you would be able to guide it magnetically toward your direction. It will turn to your spacecraft if you are close enough.

## Achievements

There are two achievements for the Captured Asteroid. Both on Medium and Hard difficulty.

* Crash at the surface of the Captured Asteroid at 200+ m/s
* Land on the surface of the Captured Asteroid

## Trivia

* It is the smallest celestial body in-game.
* Its file name is "Near\_Earth\_Asteroid.txt".
* There have been some asteroids that get captured into orbit around Earth. The most recent example of a temporary moon is 2020 CD3.
* It uses "Asteroid" for the texture.
* The sneak peek image of the asteroid has been shown to have a retrograde (clockwise) orbit, but in the release, it has a prograde (counterclockwise) orbit.
* It can give funds to the currently inaccessible Career mode. The funds given are 10 million for both entering and exiting the SOI, 20 million for going low orbit, and 50 million for landing.
Petal fairing

# Reusable Fairings

Reusable fairings include petal fairings and cargo bays. They typically work like doors, opening for payload usage, and closing again when the rocket’s job is done. In SFS, reusable fairings can not be obtained from the parts list. Instead, they require modding and/or a mechanical process. One common trait of unmodded reusable fairings are structural parts clipped into the enclosing fairing.

## Petal fairings vs cargo bays

Petal fairings are fairings that spread out in a similar way to flower buds. They require a hinge and a way to control movement (if you don’t have a motorized hinge). Cargo bays in SFS slide down to release a payload. They require at least one linear actuator, with an additional piston. Cargo bays can also open like petal fairings in real life, like with the space shuttle, but this cannot be done in the game without the usage of mods.

Petal fairings require hinges and motorization, both of which can be unstable and difficult to create. It is however, possible to add docking ports for closing more effectively. They also require a hinging space, which can be difficult to hide, and do not always have enough clearance to eject the payload. They can weigh less and balance better, and the design might be more appealing to some. Docking ports can also be added inside the fairing, and some find it aesthetically appealing to dock in that way.

Cargo bays require linear actuators, which can take up a lot of space. They can also present balance problems, and can be unstable during closing. They also sacrifice some docking capabilities only possessed by petal fairings. It is possible to add a signature docking method with cargo bays. There can be a docking arm that sweeps out, or the space station could have a special arm that fits in they cargo bay. They can also keep the design seamless, and have a half open position which would be more difficult to do with petal fairings.

Haumea

**Upcoming**
This part or feature is not in the game, but could be added in a future update, version 1.8.**Planets Expansion Required**

*Some or all of the features on this page requires the **Planets Expansion** in-app purchase.*

Haumea is a small ellipsoidal trans-Neptunian dwarf planet located in the Kuiper belt.

## Haumea

* Physics View
* Map View
* System

## Base Data

### Gravity

0.93 m/s² at poles0.24 m/s² at longest axis

## Terrain and Surface Features

Much like other icy bodies such as Europa or Enceladus, Haumea has a very smooth surface, with very little impact craters, implying that it does have tectonic activity. Due to Haumea's high albedo (reflectivity), it is thought that the surface has a thin, but icy coating of water ice and volatiles. Haumea's most famous feature is its bright red spot, predicted to exist, because the body's albedo fluctuates as it rotates rather fast.

## Atmosphere

Haumea's atmosphere is transient, very thin, and unlikely to be added. Haumea's atmosphere is made up of melted volatiles, heated by the sun, then frozen back onto the surface during the night. Parachutes would not work, due to the atmosphere's thin nature. Heat Shields would not be a priority, because the atmosphere is thin enough that substantial speeds would be required to heat the spacecraft up.

## Natural Satellites

Haumea has two tiny, icy moons named Namaka (the smaller) and Hi'iaka (the larger).

## Ring System

Haumea has a very thin ring system that orbits ~1500 km from its surface. Not much else is known about the ring.
Infinite Build Area

**Full Bundle Required**

*Some or all of the features on this page require the **Full Bundle** in-app purchase.*
The **infinite build area** cheat is a feature that will make your build space endless. This is good especially for building large rockets that cannot fit the entire building space.

This feature was added in the 1.5.4 expansions update.

A downside to this feature is, that if you build a super large rocket, the game will most likely freeze and even crash.

This feature is unlocked when you buy the Infinite Build Area Expansion.
Bugs/Pink screen bug

Version 1.5 Android-specific bug, which caused many elements of the UI, part textures, and planet textures to become pink/purple. This was an issue with the new layering system not functioning properly on Android devices with old hardware. This was resolved in version 1.5.04, in which layering was disabled on these devices. This is the cause of a non-bug in which players can see through fairings and separators.

Clouds

**Stub**

This article is a stub — it needs more information. You can help the wiki by expanding it.

**Clouds** are a visible mass of miniature liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body. Clouds are not very realistic in SFS and they are barely visible. The planets that have clouds are Earth, Jupiter, and Venus. On Earth, clouds are almost invisible because they are 10% opaque. Venusian and Jovian clouds are 100% visible due to how thick they are.

Aerodynamic Fuselage

**Parts Expansion Required**

*Some or all of the parts and/or features on this page require the **Parts Expansion** in-app purchase.*

### Mass (t)

0.2t

**Aerodynamic fuselages** or **fins** refer to parts that were introduced in update 1.4. They have 3 sizes: 4 wide, 6 wide and 8 wide. They are meant to be used to cover flat surfaces of engines wider than their fuel tanks, but can be used as an aerodynamic cover for other protruding flat surfaces.

## Other uses

* Letting Landing Legs extend beneath other parts otherwise taller than them by attaching them to the fin's underside
* Expendable and long collision buffers in impactor stages
* Nose cones
* Aesthetic parts
* Decorative tails
* Stabilizing rockets inside an atmosphere
* Can be used as taller nosecones for rockets.

## Trivia

* This part was removed in 1.5.3, replaced with the Engine Base, but it reappeared in a later update.
Expansions/Cheats Expansion

The **Cheats Expansion** allows you to use cheats. it is one of the 8 expansions of the game.

Briefly, cheats allow you to modify some of the game mechanics, such as:

* Infinite Fuel
* No Collision Damage
* No Atmospheric Drag
* No Gravity
* No Heat Damage
* No Burn Marks
* Part Clipping

## Trivia

* Part clipping is possible even without the cheat. The cheat is just a lot easier and more convenient way to do this.
* There is also a cheat named *Infinite Build Area*, but it is included in a separate expansion.
Fuel Transfer

**Fuel transfer** is a feature where players can transfer fuel from one fuel tank to another. Fuel transfer can occur anywhere as long as it is between two tanks of the same spacecraft, meaning the tanks must be docked via Docking Ports or from the same blueprint structure.

## Usage

To use the feature, tap on two fuel tanks. The fuel will transfer from the first fuel tank selected to the second one at a rate of about one tonne per second. Time warp will also speed up the transfer accordingly. To cancel refueling, tap on either of the fuel tanks. Thus, only one fuel tank can be refueled at a time. The fuel in either tank can still be used (e.g. by engines) during the refilling process.

Fuel transfer enables refuelling stations in orbit. A spacecraft that has just returned from a Space Mission can be sent to an orbiting Refueling Station, refueled, and sent for another mission.

## Trivia

* Until 1.5, if you deselected the source fuel tank and selected another one, while keeping the destination one selected, the new selected one would be used as a source for the original destination, but in 1.5, the original destination becomes the source for the newly-selected destination.
* Before 1.5, fuel tanks that does not connect together in the same plane in a rocket/spacecraft have separate fuel.
Aerodynamic Nose Cones

**Parts Expansion Required**

*Some or all of the parts and/or features on this page require the **Parts Expansion** in-app purchase.*

## Aerodynamic Nose Cones

* 1.5
* 1.0

### Code name

`Cone` (triangular)
`Cone Side` (slanted)
`Cone Round` (rounded)

### Mass (t)

0.1 (Basic)
0.15 (6 Wide)
0.2 (8 Wide)

**Aerodynamic nose cones** are eight aerodynamic parts used to reduce aerodynamic drag and for aesthetic purposes. The cone sizes are 4×4, 6×6 and 8×8 units. All cones have a light grey section on the top (except for the rounded variant), and shading along their sides, but they can be removed with Skins.

There are two types of nose cones: the *triangular* nose cone, the *sloped* nose cone, and the *rounded* nose cone. Nose cones of all sizes act identically but the types act differently because the *sloped* nose cone has slightly worse aerodynamics than the *triangular* nose cone, and the *rounded* cone has even worse aerodynamics than the other two.

Fuel tanks adapt to nose cones, and because of this, they are sometimes placed on nose cones to make larger nose cones.

## Trivia

* The grey section on the top of the cones is there for thermal protection of the cone and maximizing aerodynamic effectiveness.
* In the 1.2 update, all variants of the nose cones were unbreakable.
* Until 1.4, there used to be 2 variants of the slanted nose cone, one pointing right and the other left. After the 1.4 update, only one variant of the slanted nose cone remains, as the 'flip' feature/Symmetry Mode in the VAB rendered having more than one type useless.
* Aerodynamics were disabled in 1.4, and nose cones are used for purely aesthetic purposes, but reenabled in 1.5.
* In 1.5, 6-wide slanted, 8-wide centered and 8-wide slanted nose cones were added.
* At and above 1.5, nose cones can be skinned.
* In 1.5, the shape of the 6×6 nose cone was changed to be the 4×4 one scaled up (before that, it was completely white and had a more rounded shape). A slanted 6×6 cone was also added.
* In version 1.5.10, the rounded nose cone was added, but they are only available in 3-meter and 4-meter widths.
How to install Spaceflight Simulator

Below are ways in to install Spaceflight Simulator on different platforms. The game is available on the Android Play Store and iOS App Store, and in Steam.

## Android

Open the page at the Play Store link on your device, or a PC to remote-download it to an Android device.

For downloading directly from the Android device:

* Click on Install.
* Click on Open.

For downloading from a PC:

* Click on install.
* Choose the destination Android device (connected to the PC).
* Enter your Google Account password to confirm if needed.
* Download using an Android emulator (Like BlueStacks or LDPlayer)

After following either sequence, exit to the Android device's home screen to see a loading bar as the game downloads and installs.

## iOS

Visit the App Store through the App Store Link.

* Install the game.
* Enter your Apple ID's password to confirm the download if needed.

## macOS and Linux

macOS and Linux both have ports of the game that are available here.

* Choose between the macOS or Linux port.
	+ The Linux port is universal, and works on every distribution.
* Extract the downloaded `.zip` compressed archive.
* Run the game executable file in the extracted folder.
	+ In Linux, you will find an `x86` and `x86_64` file. Open up the one matching your computer's architecture (\_64 is the 64-bit version).

Your game data can be transferred between versions using the `SFSxxx_Data` folder.

## Windows (PC)

Steam version is out: 12 dollars (depends on region)

The version for Android can be played on a PC with the help of an Android emulator, but this is not an official way to run the game. Problems and glitches may occur, but you can run the most recent version on the Play Store at all times. Steam version out so SFS isn't supporting 32-Bit OSes now, unless you have 1.35 with ModLoader and TextureLoader, so you can make mods using Unity by adding parts and staging from 1.5

An easy instruction:

1. Download link: Forum
2. Download your version of SFS (32-/64-bit)
3. Extract the .zip-file anywhere.
4. Launch the file "SFS1.35.exe" in the SFS-1.35-directory.
5. Go to build mode "Build New Rocket".
6. Then press "t" if you want to have the full version.
7. Enjoy it!!! :)

### Alternatives

* Kerbal Space Program
* Kerbal Space Program 2
* SimpleRockets2

**Note:** If you uninstall the game, all progress will be lost. If you bought any expansions, you can restore the purchases, but not between iOS and Android.
