Thunderbirds Are Go!

Slingshot (1x9)

Air date: May 23, 2015

A malfunction at a mining operation sends an asteroid careening towards the sun, endangering crewman Ned Tedford. Alan and Kayo deploy Thunderbird 3 for the rescue mission, but a rogue solar flare knocks out their sensors. They land near the mine, and must find a way to alter the asteroid's trajectory so that it slingshots around the sun instead of crashing into it.
