China accomplished a launch website rehearsal for a brand new, improved rocket this month.
Groups on the new Hainan business area launch website performed exams with the primary Lengthy March 8A rocket together with integration with the launch pad and fueling. The brand new launcher is now set to fly for the primary time round December.
The rocket’s developer, the China Academy of Launch Automobile Expertise (CALT), says the rocket is a modified model of the Lengthy March 8. It boasts an elevated payload capability and enhanced mission adaptability and can present essential help for large-scale satellite tv for pc constellation deployment, based on CALT.

The Lengthy March 8A is an expendable rocket which might ship a payload of as much as 7.7 tons (7,000 kilograms) to a 435 miles (700 kilometers) sun-synchronous orbit (SSO). The usual Lengthy March 8 — which has launched 4 occasions thus far since 2020 — can carry 4.5 tons to the identical orbit. Each rockets use engines for its important stage and aspect boosters which burn liquid kerosene and liquid oxygen.
The brand new Lengthy March 8A achieves this higher lifting energy with upgraded second stage liquid hydrogen-liquid oxygen engines. The 8A additionally contains a payload fairing measuring 17 toes (5.2 meters) in diameter, permitting it to hold extra quantity and thus extra satellites into orbit.
The Lengthy March 8 and its 8A variant have a devoted launch pad on the new Hainan business launch website. This, together with China’s formidable constellation plans, means we’re more likely to see common launches of the rocket sequence.
A launch for the brand new G60, or “Thousand Sails”, constellation is predicted to be the primary launch from the brand new spaceport within the close to future, in accordance to CALT. First groups might want to assess the harm to the spaceport from Hurricane Yagi, which hit Hainan over the weekend.
