A Tom Corbett Space Cadet Adventure

Why has Roger Manning suddenly gone dark? Can his pal Tom Corbett really be dead? What caused the strange trouble on Titanā€”and how is it connected to a rocket race in outer space? These are but a few of the mysteries confounding Captain Steve Strong and the big Venusian engineer, Astro, as the Solar Guard races against time to save the mining colony on Saturnā€™s largest satellite. At stake are the lives of hundreds of men, women and children; the future of the intrepid Polaris crew; and quite possibly the fate of the entire star system. Book 6 in Tom Corbett, Space Cadet series.
