Season 5 is a modded single-player game in Science mode, and one goal of the season is that no kerbal dies. Last time BSSScience1 reached orbit and its lab got to work. This time the save opens on Year 2, Day 82 with 769.5 science, and the whole video goes into the next piece of the station: a docking hub. The first version never comes together, the second becomes BSSHub1, and the video ends with it climbing toward space on a night launch with nobody aboard.
Shopping for docking parts
"I brought back some science," the commentary says, and the R&D building shows plenty of it. The next node holds a batch of station parts, and their part cards get read one by one: a flexible docking port, a bi-coupler, corridors with mounts for landing legs, a four-ended corridor, a corridor airlock, a cross-way "to create big labyrinths in space," and a set of garage parts. "I don't know what I need a garage for right now."
The one that matters is the Inline Clamp-O-Tron. "This is the one I think that has a sideways connecting clamp-o-tron." The node costs 300 science, and after it is bought the total reads 469.5. A look around the rest of the tree turns up a relay dish, a fertilizer container and an experiment that needs a zoological bay, all saved for later.
A hub that won't fit together
In the VAB the build starts with a command pod, a docking port on top and three parachutes, "just in case." Then come the new corridor pieces. Cross-ways go on the main module with tubes running out to the sides, and the plan is a center that other ships can dock to. "We're just trying out stuff right now."
The parts don't always cooperate. Some pieces won't snap where they're wanted, and the new container bays hold supplies, RCS fuel and batteries on one side only. "I don't really understand these containers and why they don't snap on the other side." A planetary laboratory goes on the back, a few storage pieces finally line up, and in theory the design can take four ships at once. Then the batteries and solar panels won't attach either. "It's like when you have two different Lego sets." At about 41 minutes the VAB is cleared. "Starting over."
BSSHub1
The second try is a tall stack of Hitchhiker Storage Containers, which kerbals can pass through. Docking ports go over the windows, one per module, "so now we can attach a bunch of different stuff to this, including bigger ships." Smaller craft could dock there as escape pods. Under the stack go RCS tanks, then service bays filled with batteries, a robot core to fly it and antennas. Solar panels go on one side only, to keep the ladder clear, and the last space gets life support supplies.
"We're running out of time," and it still has no rockets. It also has no heat shield, so this one is not meant to come home: "I'm planning on just not coming back with this." Big orange tanks go on with their engines, then more around them, a nose cone, struts and fuel lines so the outer tanks feed the middle. The craft is saved as BSSHub1, "the basket space station hub 1," and the crew window shows every seat empty. It goes up without a crew.
A night launch
It is dark at the Space Center when BSSHub1 rolls out. "Throttle up and go." The engines light in a cloud of smoke and the stack climbs straight up. "It doesn't seem like it's wobbling at all."
The outer tanks fall away as they run dry. The commentary lays out the plan on the way up: "This thing is going to get up into space, and it's going to be the hub," with other modules brought up to connect to it, one for batteries and more for other jobs. Banking into the turn brings up something missing, though. "We have no fins."
Where it ends
The video stops in the middle of the climb. BSSHub1 is about 50 kilometers up, still in the atmosphere, with the game saying it will leave it in 14 seconds. It has not reached orbit yet, so whether it gets there is left for next time. No kerbal flew, and Lodlorf Kerman and Ludwell Kerman were still listed as available on the ground.
