Starfleet is less than twenty years old in 2151 and with the founding of the Federation decades away, humanity has only now been able to construct advanced warp technology capable of traveling warp 5. The Vulcans refused over the century since Cochranes warp flight in First Contact to share their advanced warp technology and the new mark of warp 5 breaks a barrier to exploration that has hindered human expansion. At warp 5, 10,000 inhabited planets are within one years journey, compared to only 18 at warp 2.http://www.section31.com/stories/july-2001/072901_c.htm
