Spear of Selene

The Spear of Selene was a shapeship that appeared in the reboot of DuckTales. It was designed and piloted by Della Duck and built by her uncle Scrooge McDuck.

Background
After Scrooge McDuck and his wards Donald and Della had gone on adventures and collected treasure from everywhere in the world, Della began thinking of exploring the greatest uncharted territory: outer space. She drew up plans for a rocketship she named the "Spear of Selene," after the Greek goddess of the moon and a personal friend of her's.

Donald was strictly against the idea, especially because she had three eggs about to hatch, but Scrooge went behind his back and had the ship built, planning to surprise his niece with it after her children were born. However, Della discovered her surprise early and decided to take it for a "test run" in orbit, and she ended up flying into a cosmic storm. Scrooge attempted to guide Della through it via radio, but the ship got struck by a bolt of lightning, and she, nor the ship, were never seen or heard from again.

Appearances
In "Woo-oo!", Donald calls out Scrooge for lying to him and taking his nephews on a dangerous adventure, and he shouts "This is the Spear of Selene all over again," to which Scrooge angrily claims he wasn't responsible for.

In "The Great Dime Chase!", Dewey and Webby find a secret room in the McDuck archive that is full of materials related to Della. They discover, framed on the wall, a note from her to Scrooge saying that she took the Spear of Selene, which makes them wonder if Della had betrayed her family and stole something from Scrooge.

In "The Spear of Selene!", Dewey and Webby arrange for the Sun Chaser to crash-land on Ithiquack so they can sneak into Selene's temple and hopefully find answers about Della or the "spear" she took. They meet Selene herself, who tells them she never owned a spear, and they conclude that the "Spear of Selene" must be something else.

In "The Secret(s) of Castle McDuck!", Huey, after Dewey tells him about his investigating, rubs the lead from his pencil on the back of Della's note, which reveals hidden information about the ship, including a drawing of it.

In "The Last Crash of the Sunchaser!", the boys and Webby resonance a torn picture of Scrooge in front of the sip, and Dewey confronts Scrooge to tell him about his mother and Spear of Selene, which he does. At the end of the episode, it is revealed that Scrooge launched an effort to find Della in space and had an army of similar-looking rockets built for his search party to go into space with, but like Della's ship, they never returned, and Scrooge was forced to end his search when it was proving costly and futile.
