Summary
Demo Flight (SpaceSail Polar Group #10) launched on a China Aerospace Science and Technology Corporation Long March 12B from Long March 12 series Pad, Jiuquan Satellite Launch Center, People's Republic of China on June 1, 2026 at 08:40 UTC. It was China Aerospace Science and Technology Corporation's 594th launch, 24th this year and humanity's 7,299th orbital launch attempt. It was the 1st Long March 12B flight. Booster LM-12B F1 flew for the 1st time and was expended. The payload was bound for Polar Orbit (PO). Qianfan Xingzuo 10-01, one of 3 catalogued objects, reached a 1,028 × 1,055 km orbit inclined 89.0°. 3 objects from this launch are catalogued, 2 of them payloads.
