If a rocket flies to any object using a direct ascent it is best for it to reach the needed speed as soon as possible because of the Hohmann effect. When it launches from the ground there is air resistance meaning it is best to have it accelerate slower at the beginning of its flight. The acceleration would probably look something like this enter image description here

What is the best acceleration rate for a direct ascent to the moon?

    $\begingroup$ @Antzi that is just for getting into space. If you want to fly to the moon, the results will be different $\endgroup$

    $\begingroup$ I don't think it differs $\endgroup$

    $\begingroup$ Having a rocket fly up and passing the Karman line is very different compared to a rocket flying so high that it reached the moon on a suborbital trajectory. $\endgroup$

  • $\begingroup$ I do not think that this question should be closed because it is not a duplicate. The linked question is different and will have different results $\endgroup$

  • $\begingroup$ I'm not sure what makes you think so ? Because the trajectory will be more upwards than horizontal ? $\endgroup$
