Chinese space startup revs up for reusable rocket race
Chinese startup LinkSpace on Saturday completed its third test of a reusable rocket in five months, stepping up the pace in China's race to develop a technology key to cheap space launches in an expected global boom in satellite deployment. LinkSpace's RLV-T5 rocket blasted off in a desert in western Qinghai province at 0230 GMT. It flew as high as 300 meters (984 feet) before returning to the launchpad on its own after 50 seconds, CEO Hu Zhenyu, 26, told Reuters.
