Transporter operations can also be curtailed when either the point of origin and/or the intended target site is moving at warp velocities. In the "TNG" episode, "", a "long-range" or "near-warp" transport was required as a transporter beam cannot penetrate a warp field. (In the 2009 "Star Trek" film Kirk and Scotty beam aboard while the "Enterprise" is traveling at warp, however, the movie takes place in an alternate continuity, thus not affecting the Prime Continuity used in all previous media and the "Star Trek" Online computer game.) To deposit an away team on the planet Gravesworld while at the same time responding to a distress signal, the "Enterprise" would only drop out of warp drive just long enough to energize the transporter beam. Geordi La Forge personally performed the delicate operation, which involved compensating for the ship's relativistic motion. After materializing, Deanna Troi commented that for a moment she thought she was trapped in a nearby wall, to which Worf replied, "For a moment, you were." In later stories ("" and ""), it was confirmed that the transporter would work at warp only if the sending and receiving sites were moving at equal velocities.
