The Jupiter United Nations Outpost, or simply Juno, is the main hub of activity in the Jupiter subsystem, serving as the bottleneck for BIFROST cargo services in this part of the Sol system.


Juno is a semi-unique station of linear-radial semimodular construction, as opposed to the eumodular structure of many other stations.

At the zenith of the vessel is the bridge, surrounded by the two rotating habitation rings - the only space in the station that has artificial pseudogravity and the main point of human activity in the station. Immediately below this is the engineering section, surrounded by the secondary (short-range) shuttle ports and the countergyro rings that inertially compensate for the hab ring's rotation. The last pressurized section at nadir is the cargo bay, complete with the main docking port and airlock for BIFROST docking.

The station is thoroughly equipped with interlinked RCS to maintain or change orientation and orbital vector, though the main engine block was jettisoned as planned upon arrival at the destination to conserve RCS fuel.


Due to the unprecedented duration of the humans' Janus I mission to the Jovian subsystem, it was clear that the Janus program's expeditions would need a large orbital base station to reside in and launch galilunar excursions from. As a result, the UNAC commissioned Minerva, a prominent technology corporation with a highly successful asteroid mining initiative, to design, construct, and deliver such a station to Jupiter.

Shortly after the establishment of the Hestia base on Vesta in 2036, construction began on the Jupiter United Nations Outpost - Juno. It was completed two years later, and after five years of rigorous testing Juno was launched. The station arrived in Jovian orbit on May 28, 2051; just one day before the first Janus crew arrived to claim it as their new temporary home.

After the Janus program's end, Juno was staffed intermittently until the UNAC arranged a schedule of regular round-trips with the BIFROST in the mid-2100s.

As of the 2200s, Juno expanded considerably (adding a second hab ring) to support the various long-term expeditions to each of the Galilean moons, and for a time became the main communications relay between the galilunar settlements.
