Season 5 is a modded single-player game in Science mode, and one goal of the season is that no kerbal dies. This stream opens on Year 1, Day 394 with 41.1 science, Eureka2 orbiting the Mun and SolarBat1 orbiting Kerbin. The plan for the day is docking: two uncrewed rockets go up to meet in orbit around Kerbin. When they will not come together, the game's own docking tutorial takes over, and it ends with the tutorial ship close to its target and out of fuel.
A plan for docking
The labs kept working between streams, and the commentary runs through what that science bought: more docking ports, different decouplers, better batteries "and then also a couple more experiments," and "the gigantic solar panels." At the Astronaut Complex only Bill Kerman and Valentina Kerman are free, with four kerbals out on missions. "Right now all of our scientists are busy," so today's craft flies without a crew.
The idea is simple: "can we have two of these things up in space and try to get them to meet up with each other and somehow dock." The design is one big tank with a Mainsail engine, fins, RCS thrusters around the sides, batteries, solar panels, two antennas, and a service bay with a docking port on top. It is not built to come home. "Then this thing will just crash in the end." After some Doctor Who jokes the VAB shows the name DockingWho1.
Two rockets, one orbit
The first one goes up fast, so fast that the throttle comes down, and it is halfway out of fuel on the climb. It still makes orbit with a short burn, "because this engine is ridiculous."
A viewer suggests the docking tutorial, but the answer is "Try this first." More fuel goes on, and a second rocket leaves the VAB under the same name. It reaches an orbit close to the first one, and with DockingWho1 set as the target, the map shows where the two paths cross.
Getting them together is another matter. The first craft just spins when told to point at its target ("I think it has no signal currently"), and the RCS seems not to work until the R key turns it on. Each burn to catch up makes the second ship faster, which carries it farther out. "I guess I have to do a tutorial." The game is saved with both craft in orbit, and the tutorial loads.
Gene Kerman's lesson
In the tutorial, Gene Kerman explains each step in a window. "Hello, today we'll be going over a very exciting process." First the two orbits have to sit on the same plane, which takes a slow, fussy burn: "Let's be really, really finicky." Then a transfer orbit, adjusted until the closest-approach markers fall within a few kilometers of each other.
The wait for that close pass drags on. "It's only 17 days that we're looping around, waiting to be close enough. I feel like I'm doing it wrong." A fresh maneuver node finally sets up the meeting, and a burn toward retrograde brings the speed relative to the target under 50 meters per second.
Docking mode
The last step is a slow approach on RCS, never faster than 10 m/s. The controls fight back: the shift key keeps firing the main engine. A look through the key bindings finds the answer, a separate docking mode on the Delete key. "Thanks Gene. Thanks for helping me buddy."
By then the ship is coming in far too fast. It slides past the target, turns back to catch up, and then: "Oh, and we're also out of fuel. We're stranded."
Where it ends
The stream ends in the tutorial, with the ship out of fuel and the target marker counting up from 3.9 km past 10 km. The lesson the commentary takes away: "modes are important. We learned a lot." In the season's own save, the two docking test rockets wait in orbit around Kerbin, not docked. Eureka2 is still at the Mun and SolarBat1 still circles Kerbin, and no kerbal has been lost.
