When the T-Mat malfunctioned, Kelly travelled with Julian Radnor to meet Daniel Eldred. They tried to persuade him to build a rocket so they could send technicians to the Moon to repair the T-Mat. With the help of the Second Doctor, Zoe Heriot and Jamie McCrimmon, the rocket was built and launched. Kelly lost radio contact with the rocket shortly after.
The T-Mat to London became operational again and Kelly used it to travel to the Moon with a team of technicians. They were unaware that Slaar and his Ice Warriors had invaded the base. Fewsham, a prisoner of the Ice Warriors, told Kelly the accident was the fault of Osgood, the former head technician, who had gone mad.
Kelly and her team repaired the T-Mat. The Ice Warriors attacked them. She was the only survivor. She escaped and rendezvoused with the Doctor, Zoe, Jamie and Phipps. Kelly repaired a device that ran on solar power and used it to kill an Ice Warrior. Fewsham repaired the T-Mat, allowing Kelly and the others to return to Earth.
Once there, Kelly viewed Fewsham's secret film of the Ice Warrior plan. Using this information, she developed a signal on the same frequency as that of the Ice Warriors. When deployed on a satellite, it led the Ice Warrior fleet into the Sun's orbit where they died.
