News Item: New speed standard announced Dateline: 6th of July, 2445; Free City, Earth With spacecraft speeds climbing ever higher and a confusing hodgepodge of systems to measure that velocity still ...persisting from the early days of space travel, The Free City Standards Committee has announced a new and definitive benchmark for indicating spacecraft speeds.
Upon the hoped for universal adoption of the standard, gone forever will be such arcane and archaic nomenclature such as kilometers per second, knots, parsecs per year or even the ancient miles per hour still used in the backwaters of the Outer Reaches.
After years of exhaustive study and no small amount of machinations, the Committee announced that the standard of spacecraft speed measurement will be Astronomical Units per year or more simply AU/yr.
Some variation of Astronomical Units have been used by Astronomers since the time of the ancient Greeks.
Nearly all young students of the sciences in Free City know that an Astronomical Unit is the approximate mean distance from the Sun to the Earth, or a little less than 150 million kilometers.
