To blast off the launch pad the first step is to throttle up (in case you’ve forgotten, the default keys are shift to throttle up, ctrl to throttle down and x to cut engines), activate SAS to hold your vertical heading and hit the staging button to launch.
Launching in that way the rotational speed of the planet is effectively acting as a head start on the speed we need to achieve to reach orbit. Instead, we need to head off at an angle after gaining a little altitude, with eastward (in the same anticlockwise direction as the planetary rotation) being the preferred heading. This need for horizontal motion is a crucial consideration – you can’t just head straight up and expect to achieve much. The first question to logically ask before trying to reach orbit is ‘what is an orbit?’ Simply put, an orbit is when you are travelling in a direction parallel to the ground at sufficient speed that when you fall back down, you miss the planet.
Today’s second part of the guide describes how to tackle the first major hurdle of any budding space program – reaching orbit.Īfter reading the last guide on how to build a successful rocket and some basic flight instructions you should be ready to try the next step in space, orbit, which is the fundamental requirement of almost every mission you could choose to undertake in KSP.
