The ANN Greer began its life as a Stream mega-transport. This was in the early days of Stream exploration, before the tech shrank and became reliable, so the transport had multiple overpowered reactors and vast spaces for all manner of cargo.
The Stream tech kept improving and quickly it became much too expensive to power the Greer, and so much cheaper to jury rig a Stream reactor to a smaller craft, a shipping container, an ATV, or even a tractor. After a bit less than a century of ferrying mega-tons around the Solar System, Greer was repurposed as a travelling research lab and long-term transport.
At the moment, she's sailing across Saturn's face in strange non-orbits, orbits that can only be attained (cheaply) with the Stream tech.
Kieran watches the muddy yellows of the gas giant being stirred up by a storm that cuts across the planet from east to west. It will soon reach its tail, the earliest disturbances the storm caused in the atmosphere as it circles the planet.
