To orbit. To station. To the next world.

KerbalX builds the Starship line: solar relays that nobody will explain, heavy stacks that actually land, and the LSI station that replaced Basic Station with ports that match the spec. MunShot is next — and we are shipping hardware while the paperwork catches up.

SOLARCOM

Relays in solar orbit. Purpose: classified enthusiasm.

KerbalX won SOLARCOM against KOEING's LLS-2 bid. Both SOLARCOM nodes are on station in solar orbit, whispering to something we are not allowed to name yet. Headcanon extension: KerbalX operates the relays under a joint-use charter — NASA owns the objective, we own the bus, and the downlink menus still say "TBD."

MunShot posture

Phase 1 wants crew control in the cabin. We are closing the gap.

The bible is clear: KOEING's R-SLS2 enters Mun planning with two clean flights and a mandated abort philosophy. KerbalX still has to prove onboard crew control for crew beyond LKO — so we are flight-testing guidance modes on uncrewed SH profiles, hardening the methane stage handoff, and rehearsing Mun-return energy on Kerbin shakedowns. Fiction, same constraints: the flashy stack has to learn bureaucracy.

Starship Heavy 4 — LSI stack, Marsproof pathfinder

Stage 1

Primary booster

High-thrust ascent and insertion. The workhorse profile that lifted LSI 1 after Basic Station was retired — a mission KerbalX treats as a line in the sand on interface discipline.

Stage 2 · Orbiter

Methane / LOX · VAJE · xenon ring

KerbalX stacks multiple propulsion idioms on one second stage: conventional methalox for impulse, KeedMartin VAJE packs for low-altitude augmentation, and a 360° xenon ion system for vacuum rendezvous and station-keeping. Tanks drop when dry; the fiction here is that every decouple event is rehearsed in Hawthorne-style sims on Kerbin with coffee nobody drinks.

1Methane / LOX — orbital maneuvering; tank assembly jettisoned once depleted.

2VAJE (KeedMartin) — air-augmented 0–25 km, gimbaled TVC, decouples with the tanks for clean aero.

3Xenon ion 360° — precision rendezvous with LSI, long coasts, and the slow ballet of docking windows.

LSI 1 operator

Replacement station. Correct ports. Crew inside.

SH-4 delivered the command module and science module with docking interfaces verified before MSC-003 arrived on KOEING's R-SLS2. Three kerbals are aboard now — first sustained station science in MSC history. KerbalX owns integration through launch; the accountability review from Basic Station still hums in the hallways, which is why every bolt has a QR code and a lawyer.

Marsproof

Paused, not abandoned. SH-4 is the pathfinder hull.

When Marsproof resumes, the same vehicle class is earmarked: deep-throttle methalox, ion cruise, and VAJE lessons folded into entry interfaces. Headcanon: KerbalX runs a private analog site outside Dusthaven where full stacks do supersonic transitions behind berms of shipping containers stenciled with motivational errors.

If you can close a fault tree while someone asks why the xenon plume looks like that on TV, you will fit in. Applications are fictional; ambition is not.
