Launch Vehicle GB-UK-R (Booster Stage)

The multi-stage rocket system (including sabotaged Stage One booster) that launches the Mars Launch Capsule. Detonates catastrophically during ascent, jettisoning the capsule to safety.

2 appearances

Purpose

Carry rescue capsule into orbit via multi-stage propulsion

Significance

Climactic sabotage target that nearly dooms Doctor and exposes alien interference; jettison success hinges on his split-second call and Cornish's override, cementing fragile UNIT-Space Control trust amid invasion stakes

Rocket launch sabotaged mid-flight

The Launch Vehicle GB-UK-R is the central artifact of this event, its systems sabotaged by alien interference. The rocket’s fuel burn rate spirals catastrophically, threatening to send the Doctor and the capsule into a solar orbit. The vehicle’s automated systems fail due to excessive heat, forcing Cornish and the Doctor to rely on a desperate jettison maneuver to avert disaster. The rocket’s trajectory and the explosion of Stage One serve as dramatic turning points, highlighting the fragility of the mission and the severity of the alien threat.

Before: Preparing for launch, with systems functioning normally but sabotaged by alien interference in the fuel bay.

After: Stage One jettisoned and exploded, with the remaining capsule shifted into a stable Earth orbit, averting a solar collision but leaving the mission in a precarious state.

Doctor demands stage jettison to avoid solar collision

The Launch Vehicle GB-UK-R, sabotaged by alien forces, spirals out of control due to a 48% overburn in fuel, sending the Recovery 7 capsule on a fatal trajectory toward the sun. Its malfunctioning systems—particularly the flame apertures, which fail to close due to excessive heat—force Cornish and the Doctor into a high-stakes gamble. The vehicle’s premature jettison of Stage One becomes the only viable option to avert disaster, with the stage exploding immediately after separation, shifting the capsule’s trajectory into a stable orbit.

Before: Operational but sabotaged; fuel burn rate at 48% excess, flame apertures jammed open, trajectory headed toward the sun.

After: Stage One jettisoned and exploded; capsule trajectory shifted into stable orbit, averting solar collision.
