China's record-breaking Gravity-1 rocket launches 9 satellites from a ship at sea (video)

The world's most powerful solid-fuel rocket just aced its third-ever mission.

Gravity-1, a distinctively squat and stubby rocket, launched Tuesday night (July 21) from the deck of a ship stationed off the coast of Shanghai.

Liftoff occurred at 10:54 p.m. EDT (0254 GMT and 10:54 a.m. Beijing time on July 22), according to the state-run Chinese outlet Xinhua, which further reported that all nine satellites reached "their designated orbits." Details about those satellites were not provided.

Gravity-1 is operated by Orienspace, a company based in the eastern Chinese province of Shandong. The rocket stands about 100 feet (30 meters) tall — less than half the height of SpaceX's workhorse Falcon 9 vehicle.

Gravity-1 consists of three core stages and four strap-on boosters, all of which feature solid rocket motors. The launcher can haul up to 14,300 pounds (6,500 kilograms) of payload to low Earth orbit (LEO), making it the most powerful solid rocket in the world. (For comparison: The liquid-fueled Falcon 9 can deliver a maximum of 50,265 pounds, or 22,800 kg, to LEO.)

The Chinese vehicle now has three flights under its belt, all of which launched from ships at sea and achieved full mission success. Gravity-1's first two flights occurred in January 2024 and October 2025.

There won't be such a long gap before Gravity-1 flies again, if all goes to plan. The rocket is expected to launch a batch of Chinese internet satellites in the next few months, according to the state-run outlet CGTN.

And Orienspace's ambitions don't end with Gravity-1. The company is also developing Gravity-2 and Gravity-3, larger, more powerful rockets that will feature liquid-fueled core stages and solid rocket boosters.

Gravity-2 could be ready to fly by the end of the year, CGTN reported. And that vehicle will likely lift off from an ocean-based pad as well.

"Sea launch of solid-propellant rockets paves the way for future launch of liquid rockets at sea," said Gravity-1 chief designer Xu Guoguang, according to CGTN. "We are also considering other methods, such as launching from drilling platforms."
