Satellites & Data
Relay networks, open datasets and the code we publish.
Aurora Mk II
A single-seat express courier that can carry urgent parcels from L5 to Mars orbit in under four days. The fastest crewed craft Halcyon has ever built.
Basilisk Salvage Tug
A rugged two-pilot tug that grapples derelicts and orbital debris, towing up to 2,400 tonnes to recycling yards.
Cascade Dropship
A heavy lander that drops 220 tonnes of cargo or 60 people onto planetary surfaces and climbs back to orbit.
Corvid Stealth Scout
A low-signature single-pilot scout used for claim verification, anti-piracy patrols and quiet reconnaissance in the Belt and Jovian system.
Eidolon Lightsail Prototype
An experimental laser-pushed lightsail designed to prove a crewed path to Proxima Centauri b, 4.2 light-years away.
Gravitas Dock Barge
A slow, enormously strong construction barge that assembles stations, docks and ark hulls in orbit.
Halcyon Starliner
A 1,200-passenger interplanetary liner with spin-gravity decks, connecting Earth, Luna and Mars on a regular timetable.
Kestrel
An inexpensive two-pilot shuttle for hops between Earth orbit, Luna and L5. The workhorse of cislunar commuting since 2179.
Leviathan Ore Hauler
An 880-metre ore carrier that moves 140,000 tonnes of refined metal from Belt smelters to Mars and Luna.
Meridian Colony Ark
Halcyon's 2.4-kilometre flagship: a colony ark carrying 4,800 settlers, their habitats and 260,000 tonnes of equipment to new worlds.
Nimbus Gas Skimmer
A skimmer that dives through gas-giant atmospheres to scoop helium-3 and hydrogen, refuelling itself as it goes.
Odyssey Deep Explorer
A four-pilot science explorer built for multi-year expeditions to the ice giants and beyond. Its closed-loop habitat supports 18 crew for up to six years.
Polaris Relay Tender
A satellite-servicing tender with twin robotic arms that refuels, repairs and upgrades relay satellites across the system.
Seraph Medevac
A fast medical evacuation ship with a twelve-bed trauma ward and surgical bay, flown by two pilots.
Sparrow Trainer
Halcyon's least expensive craft: a forgiving two-seat trainer where a student pilot flies with an instructor beside them.
Tempest Ice Runner
A rugged ice tanker that harvests water ice in the outer system and delivers it to thirsty settlements in the Belt and inner system.
Valkyrie Survey Corvette
A nimble survey corvette packed with lidar, gravimetry and spectrometry, built to map moons and asteroids for prospectors and scientists.
