Ascent of Tranquility: The launch of space shuttle Endeavour (STS-130) carrying the space station module Tranquility, seen over the frozen Charles River from Kendall Square in Cambridge MA. Due to the shuttle's motion during this 30-second exposure, it appears as a line immediately to the left of the Prudential Tower (full size for clearer view). The moon is on the left. | This large image may load slowly. Click here for a standard-size image of Ascent of Tranquility |
