The Federation orbital shuttle was a type of shuttlecraft utilized in and around Earth and the Earth Spacedock. Many of these lost power when the Whale Probe bombarded Earth with humpback whale signals in the late 23rd century. (Star Trek IV: The Voyage Home) Shuttles of this design remained in service on Earth and in orbital facilities even past the mid-24th century. (TNG: "11001001" , "Conspiracy" )
