Can China commercial satellite’s ‘octopus tentacle’ pass low-orbit refuel test?

2026.03.20 01:20 Hukeda-2 is China’s first commercial test satellite equipped with a flexible robotic arm, according to the state-owned Science and Technology Daily.

Hukeda-2, which lifted off from the Jiuquan Satellite Launch Centre in the Gobi Desert on Monday, is China’s first commercial test satellite equipped with a flexible robotic arm to capture other spacecraft, the state-owned Science and Technology Daily said. “Unlike the rigid robotic arms commonly used on space stations, this one is designed more like an elephant’s trunk or an octopus tentacle. It can bend smoothly along its length, making it more flexible and better able to adapt as it approaches a target.” Hukeda-2 lifts off from the Jiuquan Satellite Launch Centre in the Gobi Desert on Monday.

According to the report, Hukeda-2 will also test a potential solution for Earth’s increasingly crowded orbits, with a device on board that can inflate into an ultralight sphere with a diameter of about 2.5 metres (8 feet). By dramatically increasing atmospheric drag, researchers hope satellites that otherwise would take decades to fall back and burn up will be able to re-enter the Earth’s atmosphere within a year, it said. With growing numbers of megaconstellations, like SpaceX’s Starlink, such technologies are set to play a key role in extending satellite lifespans, managing orbital space more efficiently and lowering the cost of operating in
