China's Long March 7A rocket explodes 85 seconds after liftoff

China's latest rocket launch ended in failure this morning, lighting up the skies with some unwanted fireworks.

The state-owned China Aerospace Science and Technology Corporation (CASC) launched a Long March 7A rocket today (Aug. 10) from the Wenchang Space Launch Site, in the country's Hainan province, just after 8:00 a.m. EDT (1200 GMT; 8:02 p.m. local time). Around 85 seconds into the launch, the rocket exploded, generating a massive fireball and a cloud of smoke and debris while still soaring through Earth's atmosphere .

CASC had not yet released a statement about the incident by the time of this story's publication, but video reposted to social media captured the shock of onlookers the moment that the rocket burst into flames. Based on such views, the mission will almost certainly be deemed a complete failure, with total loss of vehicle and payload.

Today's launch was the 18th Long March 7A mission since the rocket's debut in 2020, which, subsequently, also ended with the vehicle's explosion . China traced that mishap to an engine malfunction that occurred shortly after first-stage separation . This morning's launch, however, didn't get that far.

The Long March 7A's four side boosters and core stage detach as a full cluster during first stage separation, which typically occurs just under three minutes after liftoff. As today's incident occurred just 85 seconds into flight, the rocket was still engaged in the main stage's initial engine burn to escape Earth's atmosphere.

The 7A — a variant of China's Long March 7 rocket family — stands just over 197 feet (60 meters) tall and combines the first two Long March 7 stages with a hydrolox (liquid hydrogen and liquid oxygen)-powered third stage capable of launching up to 7 tons to geostationary transfer orbit (GTO).

According to China National Radio , today's launch carried China's Zhongxing-4B spacecraft,, a communications satellite presumably bound for GTO. China's Zhongxing satellites provide telecommunications and broadband internet services and are also thought to provide services for China's military.

It is unclear what repercussions today's explosion may have on upcoming launches, including a Chinese Zhuque-3 rocket liftoff scheduled for Monday evening. That mission is scheduled to fly from China's Jiuquan Satellite Launch Center, more than 1,500 miles (2,415 kilometers) from Wenchang, at 7:45 p.m. EDT (2345 GMT; 7:45 a.m. local time), and is expected to feature a first-stage landing attempt.

CASC uses the standard Long March 7 rocket, which shares its core stage with the 7A, as its launch vehicle for delivering cargo to the Tiangong space station in low Earth orbit about every eight months. The most recent of those missions launched in May , putting the next resupply launch sometime around January 2027. Depending on the cause of this morning's explosion, that mission and others could face delays as China investigates the incident.
