A shuttlecraft of the USS Voyager in which Kathryn Janeway and Chakotay crash on a planet in 2373, the starting point of Janeway's repeated visions of her own death.
The Sacajawea was one of Voyager's shuttlecraft, named after the Shoshone woman who guided the Lewis and Clark expedition.
In Coda, Janeway and Chakotay are returning in it from a survey when an electrical storm brings the shuttle down on a planet. Janeway is gravely hurt. What follows is a string of scenes in which she seems to die again and again, in a Vidiian attack, in a shuttle explosion and from the phage, each time starting over aboard the Sacajawea.
The loops are the work of an alien presence that has entered her mind in the form of her late father and wants her to go willingly into its matrix. In reality she never left the crash site, where Chakotay and the Doctor are fighting to revive her.
