It looks like another homage to an episode from the original series will be the episode for next Saturday.
Sunprobe was a hair-raising experience in the previous Generation and there was so much tension it was almost uncomfortable.
With Probe heading straight for the sun due to a failure with the ship's close distance to the sun it required International Rescue with a two-pronged Rescue attempt with Tin-Tin (now Kayo), Scott & Alan racing through space in Thunderbird 3 with Brains & Virgil making an attempt from Earth on Mount Arkan (which I'm guessing was meant to be a mountain taller than Everest) with the Satellite Truck.
This time around sees a mining core on an asteroid whose direction goes deadly off-course requiring Kayo & Alan in Thunderbird 3 to head into deep space to avert a deadly crisis from happening.
It seems promising from the out-set. And it's taking a previous concept but tweaking it enough for the new age.
Covering the 1st Thunderbird Series in 50 years with the Build up 'Before the Storm' and After the Storm.
