'Drama at Space City' by Anthony Marriott

While Steve and Venus go on a skating holiday, Professor Matic gives Robert an overhaul, and Zoonie stays with Commander Zero’s son, Jonathan. After causing mayhem in the control centre of Space City, Jonathan and Zoonie ask Zero for a trip in Fireball XL5, but the Commander – now at the end of his tether – flatly refuses. However, after a reconditioned Robert is put on board XL5, Jonathan and Zoonie sneak on board; then Zoonie’s cry of “full power” causes the robot to start the engines – sending the ship and its three occupants flying off into space…
