When he told her he was a stowaway and she offered to get him a drink on the house , he decided to take her on a teleport trip down to Earth . There they met Wilfred Mott , who told them people had abandoned London because of all the alien invasions at Christmas time . The Doctor and Astrid were teleported back to the ship , where the Doctor noticed that the " Titanic ' s " shields were down and three asteroids were on course to hit the ship . He complained to the steward , but the asteroids hit the ship and killed most of the passengers apart from the Doctor , Astrid and a few others including Rickston Slade , Foon Van Hoff , Morvin Van Hoff , Mr Copper and Bannakaffalatta .

Astrid used a teleportation bracelet to get to Deck 31 to help the Doctor . To save the Doctor and defeat Max Capricorn , she lifted Capricorn and his life support system with a forklift and threw him into the engines . The forklift ' s brakes were cut by a halo thrown by a Heavenly Host . She plunged to her death along with Capricorn , but was dematerialised by an automatic function of her teleport bracelet . Using the advanced transmat system , the Doctor tried to recover Astrid , but only succeeded in creating a partially cohesive , non - corporeal form , neither truly alive nor dead .

( TV : " Voyage of the Damned " ) Behind the scenes . Astrid was originally simply named Peth . ( REF : " " ) Astrid is an anagram of TARDIS . The name Astrid ( Old Norse : Ástríðr ) is of North Germanic origin , literally meaning " fair goddess " ( áss ( goddess ) and fríð ( fair ) ) . Peth is Welsh for " thing " . While implying that Astrid ultimately has some connection to the Doctor ' s time - ship , this proved to be unfounded in the episode . The British newspaper " The News of the World " released a report before Kylie Minogue was officially cast as Astrid , claiming incorrectly that her character would be a sexy Cyberwoman . As with most " one - time " companions , Astrid ' s actual status as an " official " companion is a matter of debate among fans . ( See also Sara Kingdom and Grace Holloway ) Astrid ' s case is strengthened by the fact that during the course of the story she is directly invited to join the Doctor , much like Grace Holloway , and she accepts . Unlike Grace , however , she dies before setting foot in the TARDIS .
