Learning of Frazer's sabotage, Nolan and Shroeder realise that they have no way of warning the Spectrum officers because Crater 101 is beyond radio range. They instead try to send a signal by firing an unarmed CB29 rocket into the crater. The CB29's arrival reminds Scarlet of the inscription on a good luck charm that Nolan gave him: in 2058, Nolan oversaw the launch of a Neptune-bound CB29 space probe that reached its destination "ahead of schedule". Repeating this phrase, Scarlet realises that the atomic device will detonate prematurely. He orders Blue and Green to return to the Moonmobile and clear the area while he attempts to extract the crystal. After much effort, Scarlet succeeds and escapes in the Lunar Tractor seconds before the nuclear explosion engulfs the crater and destroys the Mysteron complex. Scarlet, Blue and Green return to Earth with the crystal.
