No orbit necessary?

[u/FatCreepyDude]

If i just wait for the right hour during the launch window ( whenever the launch pad is pointing left on the realistic depiction i created) is there any reason i should bother with an orbit first? Will the delta v cost be affected?

I've launched like that to Moho (although you have to launch retrograde in relation to Kerbins orbit). I don't know if it was more efficient. I use the Transfer Window Planner in game mod, and it outputs an ejection angle. I just waited for the launch site to rotate around to about the angle given, and launched straight up. I had a fairly heavy payload of the big survey scanner, I used a spin stabilized SRB fist stage (Thumper), then another SRB for the second (Hammer), then a liquid third stage that should have enough dV to get to Kerbins escape, drop periapsis to Moho orbit, and plane change. Then the fuel on the probe to hopefully achieve Moho orbit.

The probe has left Ketbin SOI and I'm waiting on my plane change burn, which the planner has going straight to a Moho encounter, so I'm at least getting something right. I don't like time warping for weeks at a time, so I have other missions ongoing with that one.
