Battlestar Galactica (BSG)
The FTL, or "Faster Than Light", drive is a propulsion technology that allows spaceships to achieve superluminal travel. It functions along the basic principles of a jump drive, with a ship disappearing from its initial location and reappearing instantaneously in a new location.
In the miniseries (2003), some crewmembers are shown reacting with nausea and/or vertigo when undergoing a jump, though no harm appears to come to living beings even after many jumps. Making a jump eventually proves damaging to the ship's armor and structure in later episodes, after several years of continual combat and metal fatigue have taken their toll on the elderly ship. An FTL jump can be executed in the gravity well of a planet (indeed, Galactica jumps in and out of a planet's atmosphere in the episode "Exodus, Part II"). Nonetheless, it is preferred not to jump too close to a planet, not necessarily because of any physical limitations, but because if the coordinates are calculated wrong there is a risk that a ship might jump too close to the planet and crash into it, or reappear within the planet (This happens to a Raptor in the episode "Lay Down Your Burdens"). Further, a BSG FTL drive can theoretically travel anywhere in the galaxy; the limiting factor is not the drive itself, but the finite distance that the navigation computer is able to safely calculate a jump trajectory; more advanced computers are able to calculate longer range jumps (e.g. the Cylons have better computers and have an effective jump range at least three times that of the Colonials). The extreme distance that a safe jump can be plotted is called "the Red Line", and while a vessel might jump a theoretically infinite distance beyond that, it is possible the vessel could end up colliding with a star, asteroid, or other space debris.
I thought the name was cool, but I had no idea what was implied... is Diaspora following the same story as BtRL, or is it completely different? I suppose I should research these things. However, if someone has a quick recap handy off the top of their head, I would appreciate it.
