Gravity-1 mission 1 launch 11 January 2024

Gravity-1 (Chinese: 引力一号) is a solid-propellant medium-lift launch vehicle designed, manufactured and launched by Chinese aerospace company Orienspace. It can carry a payload of up to 6.5 tonnes (14,000 lb) to LEO or 4.2 tonnes (9,300 lb) to SSO, enabling the deployment of large-scale satellite constellations. Its maiden launch was conducted from a sea launch platform on January 11, 2024, breaking records as both the world's largest solid-fuel carrier rocket and China's most powerful commercial launch vehicle to date.[1]

Gravity-1 consists of seven solid rocket motors (SRB) in total. The first four side-mounted SRBs are ignited on the ground, while three core boosters are air-lit in sequence. The launch cost for Gravity-1 is no higher than US$39 million. Gravity-1 offers a quick-response-time of only five hours between manufacturing completion and launch. Orienspace has signed contracts for the launch of more than one hundred satellites. [2]
