Bus Ø
1.78 m
A three-axis-stabilized interstellar spacecraft. Scroll to assemble each subsystem from its exploded technical view.
42.7 AU from origin · signal delay 05:54:11 · nominal
The decagonal bus houses flight computers, attitude-control electronics and hydrazine propulsion. Every subsystem mounts to this frame.
A honeycomb-aluminum reflector skinned in graphite-epoxy laminate — the probe's voice across interstellar distance, always pointed home.
Each generator holds 24 pressed plutonium-238 oxide spheres, delivering electrical power without sunlight — mounted outboard on a deployable boom.
Extended booms isolate sensitive magnetometers and particle detectors from the bus, while the steerable scan platform carries imaging and spectroscopy.
A 12-inch phonograph record of sounds and images from a distant world. Its cover bears an ultra-pure uranium-238 sample — a clock that runs for billions of years.
