First Flight

Lore & Background

Before the First Flight, the Kerbal Space Center was little more than a collection of workshops, a launch pad, and a handful of enthusiastic Kerbals tinkering with engines and fuel lines. Bill Kerman ran experiments in the science bay. Bob Kerman argued over structural loads in the hangar. And Jebediah Kerman sat in the command pod, waiting for someone to tell him it was safe to light the burn. The tutorial guidance—patient, step-by-step, almost maternal—walked the crew through every check: fuel levels, throttle response, parachute deployment. It was less a mission briefing and more a parent making sure the child remembered to fasten the seatbelt.

The launch itself was unglamorous by the standards of later Kerbal achievements. The solid boosters lit first, shaking the whole structure with a violence that made Jebediah's eyes go wide. Then the main engine roared to life, and the rocket climbed—slowly at first, then with gathering speed, punching through the thin lower atmosphere of Kerbin. The Kerbals on the pad watched the little column of smoke trace its arc against the blue sky. When the pod dropped away and the parachute bloomed, and Jebediah set down on the grass with a gentle thump, the entire KSC erupted in cheering.

In the broader KSP narrative, the First Flight is the 'origin story' that every new pilot experiences. It is the moment the player transitions from spectator to participant, from reading about spaceflight to feeling the G-forces in their own hands. The community has built an almost mythic reverence around that first successful (or spectacularly unsuccessful) launch, because for every Kerbal, the sky started on that single day.

In Their Own Story

The pad was quiet in the way that only a held breath can be. Jebediah could see his own reflection in the viewport—green, round, slightly panicked—and beyond it, the flat expanse of the KSC apron, the white hangar, the pale blue sky of Kerbin stretching endlessly. Bob's voice crackled over the comms: 'Throttle's yours, Jeb. You know the drill.' The drill. As if there had been a previous drill. As if anyone had ever done this before. He pushed the throttle lever forward, just a little, feeling the engine shudder to life beneath him. The boosters caught. The world turned to rumble and vibration. The sky tilted. The ground fell away. And for the first time in the history of his species, a Kerbal was not standing on Kerbin. He was above it. He laughed. He was absolutely, completely sure he was going to laugh the entire way down.

Reader's Guide

OBJECTIVE: Assemble a basic rocket in the VAB, launch it from the KSC pad, achieve a safe suborbital or low-orbital arc, and recover the pilot.

DIFFICULTY TIER: Beginner / Tutorial. This is the onboarding mission for every new Kerbal pilot and the narrative foundation of the entire program.

KEY DECISIONS: The pilot chose between a simple single-stage design and a two-stage configuration. Solid boosters were attached for initial thrust, but their burn duration was short, meaning the main engine had to sustain the climb. The pilot had to manage throttle carefully—too aggressive and the structural loads would tear the vehicle apart; too gentle and the rocket would stall in the dense lower atmosphere. Parachute deployment timing was critical: too early and the vehicle would tumble; too late and the landing would be a crater.

OUTCOME: The rocket climbed, the boosters separated with a satisfying bang, the main engine carried the vehicle to apogee, and the command pod separated cleanly. The parachute bloomed. Jebediah touched down on the grass with a soft bounce. Mission accomplished. The KSC team cheered.

WHY IT MATTERS: This is the moment the player stops watching and starts doing. Every subsequent mission—Mun orbit, Moho flyby, Jool system exploration—carries the emotional weight of that first successful launch. The community's shared memory of 'my first flight' (whether triumphant or a spectacular explosion) is a bonding ritual unique to KSP. It is the origin point of the entire Kerbal space program narrative.

Did You Know?

• The default pilot for the First Flight is Jebediah Kerman, one of four named Kerbals available at the KSC alongside Bill, Bob, and Valentina.
• The tutorial that guides the First Flight is written in a gently encouraging, step-by-step tone, treating the player as a complete novice and walking through every single button and check.
• In the KSP universe, Kerbin's atmosphere and gravity are tuned so that a basic tutorial rocket can achieve a safe suborbital arc without requiring advanced aerodynamic design, making the First Flight accessible to any ne
• The First Flight experience is the narrative and mechanical starting point for every single player who opens KSP, making it the most 'experienced' mission in the game by sheer volume of attempts.
