Chinese startup LinkSpace revs up for boom in reusable rockets

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, said.

The Beijing-based company aims to launch its next-generation RLV-T16 rocket next year that will be capable of reaching an altitude of up to 150 km, Hu said.

In two tests in March and April, the RLV-T5 hovered at heights of 20 and 40 meters, respectively.

China envisions constellations of commercial satellites that can offer services ranging from high-speed internet for aircraft and rural areas to tracking coal shipments and commuter traffic.

Reliable, low-cost and frequent launches will be key, with recoverable or partially recoverable rockets like the Falcon 9 from Elon Musk’s SpaceX one path to eventually affordable satellite deployment missions.

SpaceX has already used recoverable rockets on a number of orbital missions since its historic launch early in 2017, spurring Europe, Russia, Japan and China to speed up their own research into the technology or at least consider studying it.

LinkSpace’s test flight on Saturday came on the heels of a historic satellite delivery into orbit last month by privately owned Chinese firm iSpace. Beijing-based iSpace said a week earlier that it was planning to launch a recoverable rocket in 2021.

The reusable design of its next-generation rocket could lead to a predicted cost reduction of 70 percent, iSpace estimated.

LinkSpace previously said it hoped to charge no more than 30 million yuan ($4.25 million) per launch.

That is a fraction of the $25 million to $30 million needed for a launch using a Northrop Grumman Innovation Systems Pegasus, a commonly used small rocket. But the Pegasus is launched from a high-altitude aircraft and is not reusable.
