Alien Space Capsule (Mars Probe 7)
The Mars Probe 7 capsule is a space re-entry module of unknown origin and design, originally launched as part of a human Mars mission but now exhibiting behaviors that defy human engineering. It first appeared hurtling toward Earth on an erratic, unstable trajectory that no standard recovery protocol could predict, only to stabilize its descent with retro jets that ignited with non-human precision. When recovered, the capsule was sealed and potentially dangerous, its derelict state hiding months of radio silence from Mars and the fate of astronauts Michaels and Lefee. It became the focus of UNIT and the Doctor's investigation after conspirators hijacked its transport convoy, escalating fears of alien sabotage. Later, the capsule was repurposed for pre-launch preparations, with the Doctor confined inside monitoring fuel and coordinating with Space Control. Despite its use as a functional spacecraft, the capsule's true nature—what it contained, what it was, and whether it was ever truly human—remained an unresolved mystery that shaped the Doctor's mission.
