However in making a generations long voyage close formations were deemed unwise. There were practical considerations as well. Over time, slight differences in velocity and trajectory created great distances spanning from the lead vessel to the last. This was purposeful. As rogue worlds or whole systems of planets and stars came and were passed, the lead vessel would often use slight assertions of propulsion to enter and orbit. Expeditionary ships and landers would explore worlds and survey them for whatever purpose.
As the fleet passed through, if required other vessels would similarly orbit and harvest resources before using gravity wells to sling themselves free of the system. Each vessel would follow a carefully laid out plan and timing. The first vessel to enter was usually the last to leave. And as this cycle repeated periodically over time, each vessel would in its time be the first and last to visit a world, star or stellar object. It was in this manner that the White Fleet arrived
In the system they labelled Arda 922 the Scions of Numenor reached their middle way point on their long journey. Years hence some but not all would venture forth as they had before after visiting a new system.
