The at rest distance between Betty the astronaut and a flag in open space is [itex]1[/itex] unit. If Betty approaches the flag at constant speed while laying out metre rulers, will she have laid out [itex]1[/itex] unit of at rest rulers when she reaches the flag? Or will the number of rulers laid out exceed [itex]1[/itex] due to length contraction?
