Chinese commercial rocket firm Galactic Energy, developer of the CERES-1 rocket, has improved sea-based launch technology to provide enhanced launch services for satellite deployment missions.

Since its first launch in 2020, the CERES-1 has made itself a symbol of China's commercial satellite industry, becoming one of the earliest reliable options designed and produced in the country.

The latest rocket, a sea-borne variant of four-stage launch vehicle, blasted off at 16:12 (Beijing Time) from the waters surrounding the eastern province of Shandong, placing a group of four satellites into planned orbit.

It was the rocket series' 12th flight mission.

"After this launch, we plan to complete four more sea-based launches this year. By combining sea-based and land-based launches, we aim to provide enhanced launch services for different satellite deployment missions in the market," said Liu Baiqi, founder of Galactic Energy.

Combining solid-state propulsion in its early stages and liquid propulsion in its last stage, the CERES-1 is adaptable to mission requirements and capable of meeting diverse launch payload demands.

Galactic Energy's bid to optimize its offshore launch capabilities may allow the company to push its advantage even further, reducing transport costs and improving launch positioning.

Faced with the uncertainty of sea-based launches, the research team has managed to address technical challenges to ensure safety.

"We have developed a low-cost locking and releasing mechanism to fasten the rocket before the launch and release it during the launch from the ship. We have also resolved the issue of rocket orientation and stabilization in case of hull shaking, enabling precise positioning, orientation, and navigation of the rocket," Liu said.

China unveils first self-developed mega hot isostatic pressing equipment

2024-07-20 11:37 Last Updated At:12:07

China on Friday unveiled its first self-developed mega hot isostatic pressing (HIP) equipment, marking a significant breakthrough in the material manufacturing sector.

As the largest of its kind in China, this newly released HIP equipment excels in densifying and optimizing large and intricately shaped materials under ultra-high temperature and pressure.

The HIP is a key technology used in producing high-performance materials, significantly enhancing their wear resistance, corrosion resistance, and mechanical properties.

"In simple terms, this equipment transforms ordinary materials such as metal or porcelain into high-performance ones. Through HIP, material performance is greatly improved, and the average fatigue life of the material can be increased by at least ten times, meeting the needs of extreme working conditions," said Qi Wen, leader of the mega HIP equipment project.

With wide applications, the HIP technique is suitable for both metal and non-metal materials, such as porcelain or glass. This mega equipment will advance the development of China’s aerospace, oil and gas, and machinery manufacturing sectors, enhancing China's competitiveness in the international material manufacturing arena.
