Chinese Long March 3B Rocket Survives Lightning Strike During Ascent

A Chinese Long March 3B rocket was struck by a direct lightning bolt during its ascent on July 23, 2026 [1, 2].

The event raises questions about launch weather protocols and the resilience of aerospace hardware against atmospheric electrical discharges. While lightning is a known risk, the ability of a vehicle to sustain a direct hit and still complete its primary mission is a significant technical outcome.

The strike occurred 30 seconds after liftoff ^[2]. Despite the impact, the rocket continued its journey and successfully delivered the Tianlian-2-06 relay satellite into orbit ^[2]. The mission was conducted by the China Aerospace Science and Technology Corporation (CASC) [1, 2].

Experts said that rockets are particularly susceptible to such strikes due to the nature of their propulsion. The exhaust plumes generated during ascent can lower the breakdown voltage of the surrounding air [2, 3]. This process creates a more conductive path, which makes a lightning strike more likely as the vehicle climbs through storm-heavy layers of the atmosphere [2, 3].

Space agencies typically employ strict weather rules to avoid launching during active electrical storms. However, the Long March 3B's survival suggests that the vehicle's shielding and electrical systems were capable of absorbing and diverting the surge without compromising the flight computer or engine performance ^[2].

The successful deployment of the Tianlian-2-06 satellite indicates that the payload remained protected throughout the atmospheric disturbance ^[2]. This result provides data on how modern orbital launch vehicles handle extreme weather anomalies in real-time [2, 3].
