Comet Chasers is an episode of Thomas' Adventures of Thunderbirds Are Go ( 2015 TV Series).
Halley's Comet is passing close to Earth, and businessman Francois Lemaire goes on an ego trip with his unimpressed wife Melanie aboard his space yacht Solar Wind, so as to send live pictures back to Earth. Disaster strikes when Francois flies into the comet's tail, damaging his ship and causing it to lose contact with Earth. Thunderbird 3 is dispatched for search and rescue with Percy, Toby, Daisy, Alan and Scott on board, Alan being particularly keen to see Halley's comet as it will be another 75 years before the comet passes Earth again, and Daisy being so excited to meet a famous person like Francois Lemaire, but it isn't long till she has to pull off a daring rescue, even though 'space travel is bad for her swerves', as she says!
