Description

A stock rocket called Day One Orbiter. Built with 25 of the finest parts, its root part is mk1pod.v2.

Built in the VAB in KSP version 1.5.1.

Decided to start a stock game on 1.5.1 and try to get to orbit on day one without dV or TWR information. This is the result. It will easily get you into a 100k+ orbit with room for error.

(I added Engineer Redux later, for this screenshot and to see what the values were for my own curiosity. TWR is not optimal… you may - or may not - get even more mileage out of this by tweaking the booster thrust for more balanced TWRs.)

Recommend turning slightly East almost right away, gradually increasing to 45 degrees, per usual. Cut the engine at 75k projected apoapsis, chill a moment, then full burn for orbit 1m from apoapsis. You will run out of fuel and punch the third rocket stage mid-burn. Be ready.

Ablator is set to 20… you won’t need more unless you add something or come streaking toward the planet like an asteroid. Make your orbit 75k-round before deorbiting for safest available return trajectories.

Drag chutes and Mk16 are set to fire when safe, at near optinal pressures and altitutes. Punch the final stage as soon as you’re through the clouds and let the chutes do the rest. I was able to put the capsule down just offshore the KSC runway… hard to get better than that on day 1.
