"We who are about to die,
salute you."
Before you start:
It is recommended that you laminate
this guide.
When you see a “ ”
You should leave
a tick/cross in DRY WIPE marker
according to your current situation.
Failure is always an option.
Good luck and have fun exploring the
KSP Basics:
Delta-V - In astrodynamics a Δv or delta-v (literally “change
in velocity”) is a measure of the amount of the effort that is
needed to change from one trajectory to another by making
an orbital manoeuvre.
L”X”O – Low “Enter Planet Name Here” Orbit. For
example, LKO = “Low Kerbin Orbit.”
Escape Velocity – The velocity required to exit a planet’s
sphere of influence.
Periapsis (Pe) – The lowest point in your orbit.
Apoapsis (Ap) – The highest point in your orbit.
Prograde/Retrograde – Prograde is “forward relative to the
direction of movement” it will increase your orbital
velocity.Retrograde is “backwards relative to the direction of
movement” it will decrease your orbital velocity.
Navball – Used to get your bearings and to navigate when in
space.
Thrust-To-Weight-Ratio – TWR for short is a ratio that
defines the power of a craft's engines in relation to its own
weight. If a
craft
needs to get into a stable
orbit
or land safely
on the current
celestial body
without using
parachutes
, then
its engines must put out more thrust than its current weight to
counteract gravity. In the terms of a ratio, a craft with a
greater thrust than weight will have a TWR greater than 1.
Inclination - The tilt of the orbit is given by the inclination.
Usually the value is given in degrees where the value is given
between –90° and 270°. An inclination of 0° or 180° is
equatorial, so the craft is always above the equator.
Navball Point of Reference - As all movement in space is
relative, the point of reference determines the object from
which all distance measurements and velocity vectors are
made. Clicking this area will toggle the point of reference
between Surface and Orbit, as indicated by the green text. If a
target is selected, there is a third option, Target. Changing
the point of reference changes the location of the prograde
and retrograde markers.
Manoeuvre Nodes - A maneuver node is a planned velocity
change along an
orbit
. Multiple maneuver nodes can be
added which will affect the following maneuver nodes. After
adding a node it shows the velocity change needed to reach
the next new orbit next to the
navball
.
Manoeuvre Node Directions –
Prograde/Retrograde - These vectors directly change the
speed of the craft. Burning prograde will increase velocity,
raising the altitude of the orbit on the other side, while
burning retrograde will decrease velocity and reduce the orbit
altitude on the other side.
Normal/Anti-Normal - The normal vectors are orthogonal to
the orbital plane. Burning normal or anti-normal will change
the orbital inclination. On the navball the normal and
anti-normal vectors are located on the equator line directly
between the prograde and retrograde markers.
Radial in/Radial out - The radial-in vector points directly
toward the center of the orbited body (center of the brown
hemisphere on the navball), while the radial-out vector points
directly away from it (center of the blue hemisphere).
Performing a radial burn will rotate the orbit
around the craft like spinning a hula hoop
with a stick. Radial burns are the least
efficient way of adjusting one's path - it is
much more effective to use prograde and
retrograde burns.

Mass –
“The centre of mass, abbreviated CoM,
or centre of gravity, is the location of an object where all
mass is equally distributed around it. It is important to
balance a
craft
to prevent it from getting out of
control.
Planes
should have a centre of mass slightly in front of
the
centre of lift
. For all craft the thrustvector should point to,
point away from or go through the centre of mass.” – Kerbal Space
Program Wiki
Centre of Mass (Yellow)
Centre of Thrust (Pink)
Thrust –
“The centre of thrust or thrustvector is the
direction in which the thrust is acting and on which point the
thrust acts on the
craft
. The thrustvector and
centre of
mass
should be in one line to minimize steering.” – Kerbal Space
Program Wiki
Lift –
“The centre of lift is used mainly when creating
planes
, it shows the axis and direction of lift provided
by
wings
,
control surfaces
and
winglets
. Inside the editor it is
showed as a cyan-coloured sphere (axis) along with an arrow
(direction of the lift). The centre of lift should also always be
behind the centre of mass.”– Kerbal Space Program Wiki
Kerbin
“
A unique world, Kerbin has flat plains, soaring mountains and wide, blue oceans. Home to the Kerbals, it has just the right conditions to support a vast, seemingly undepletable population of the eager green creatures.” –Kerbal Astronomical Society”

orbit too late. The
top red carrot is where I will be, and the bottom carrot is where
my target will be. I need to push my apoapsis farther away.
Remember that burning directly prograde will raise your
apoapsis further, so you will also have to burn slightly down in
pitch to keep your apoapsis at the altitude you need.

Science Modules:
Mystery Goo™ Containment Unit:
“The Mystery Goo™ Containment Unit is a science part used to expose a goo to atmospheres and vacuum in attempts to gain science from observing the goo inside. This can be achieved either via action group or right clicking the container and clicking observe mystery goo. The unit cannot be reused after its results were transmitted, unless it is cleaned via the Mobile Processing Lab MPL-LG-2. Like EVA reports, the science gained from observing the Mystery Goo varies depending on different conditions in flight.” – Kerbal Space Program Wiki
SC-9001 Science Jr.
“Science Jr. is the more advanced scientific sensor. It is used to
retrieve science points and to complete science experiments in space or other celestial body. The unit cannot be reused after its results were transmitted, unless it is cleaned by theMobile Processing Lab MPL-LG-2.” – Kerbal Space
PresMat Barometer:
“Displays atmospheric pressure to five significant figures, while active. A pressure below 0.0001 is shown as vacuum by the sensor. Lower atmospheric pressures markedly reduce lift and drag induced by the atmosphere, and cause a small change in engine efficiency.” – Kerbal Space Program Wiki
GRAVMAX Negative Gravioli
Detector:
“This instrument shows the gravity in your current sphere of influence to a maximum of 4 significant figures and two decimal places. This can be used with altitude to estimate the mass of the nearest celestial body or to measure its surface gravity. Alternatively, it can be used with the
accelerometer and altitude to make landing estimates.” – Kerbal Space
Program Wiki
2HOT Thermometer:
“The 2HOT Thermometer displays temperature to 5 significant figures when activated and right-clicked. There is no unit shown but it is assumed to be degrees Celsius. The 2HOT cannot be used to earnscience while distant from a celestial body, although it will continue to tell the temperature.” – Kerbal Space Program Wiki
“The Mobile Processing Lab MPL-LG-2 allows scientific data to be transmitted with higher efficiency and to reuse the Mystery Goo™ Containment
Unit andSC-9001 Science Jr. after transmitting their result. The module needs its full capacity of two Kerbals to work. Note that it is not a command module; any craft it's a part of will need a probe body or command pod to be piloted. Using the module consumes electricity” – Kerbal Space Program Wiki

Hohmann & Bi-Elliptical Transfers
Hohmann Transfer:
A Hohmann transfer is a technique that involves burning your
engine twice whilst in orbit in order to reach a higher orbit.
You start off by burning prograde at your periapsis until you
reach the desired altitude for your apoapsis. You will now
have an elliptical orbit. Next you have to travel up to your
apoapsis and burn prograde once
again in order to raise your
periapsis to the same altitude as
your apoapsis. Like so:
A Bi-Elliptical transfer is similar to a Hohmann transfer
although it requires one extra step. Most of the time the
Hohmann technique is more useful but in some cases using a
Bi-Elliptical transfer can save you Delta-V!
You start a Bi-Elliptical transfer by burning prograde from
your periapsis in order to raise your apoapsis. Again, making
an ellipse. Once you are at apoapsis, you burn prograde to
raise your periapsis to your desired orbital altitude. After
travelling to periapsis, you want to burn retrograde and bring
your apoapsis down to roughly the same altitude as your
periapsi. Like so:

Gravity Assists:
“
A gravity assist is a maneuver in which you use a flyby of a secondary celestial body (such as a planet or moon) to alter your orbit about the primary (typically the sun, but occasionally a planet: forinstance, when navigating the Joolian moon system). Gravity assists are useful because they allow you to gain or lose orbital energy or make expensive maneuvers such as plane changes for free; however, they are difficult to set up and require careful planning and lots of patience. That said, once
you master them, you can manage feats you wouldn't have thought possible.
”
–Stochasty1. Firstly, you have to put yourself into a transfer orbit, ensuring that the celestial body is travelling in the direction you want to go in.
2. Time Accelerate until you reach the SoI of the celestial body.
3. Plan another course correction manoeuvre at Periapsis to increase your Apoapsis height after leaving the SoI, it is most effective when you are closer to the body, but ensure you won’t collide with anything and that you won’t be accidentally aerobraking.
4. Time Accelerate until you leave the SoI of the celestial body.
5. When you check the map you will notice that your Apoapsis height has increased.
6. You can repeat this, changing your course when furthest away from the
body you are getting a gravity assist from, until you have reached a the SoI of another planet or anywhere really.
7. You can use gravity assists to go from Kerbin to Duna, or Jool to Kerbin without using a lot of fuel. It is one of the most efficient ways of
8.
You can perform a powered gravity assist. Accelerating at your periapsis has the greatest effect on your apoapsis. This still applies to yourperiapsis during a gravity assist. When you accelerate during your fly-by, fuel is used very efficiently to increase the apoapsis of your final
trajectory. This is a very difficult technique because it is hard to control your final trajectory even when using a manoeuvre node but can save a lot of time and a lot of fuel.
