Personal firm House Epoch handed an important check, forward of aiming for orbit later this 12 months.
Chinese language rocket startup House Epoch placed on a present lately, with an indication check launch of their reusable Yanxinghe-1 rocket booster.
The check launch occurred on the Oriental Spaceport business launch web site in Shandong province, and lasted 125 seconds. The Yanxingzhe-1 rocket reached an apogee of two.5 kilometers shortly after launch, descended, re-lit its engines and carried out an ocean soft-landing shortly after. Although the booster slowly sank into the ocean after landing, the launch and check was successful.
The check was essential to reveal full thrust, variable thrust adjustment, shutdown and restart of the engine. Free-descent, glide and hover forward of touchdown was additionally carried out.
The rocket is an revolutionary design, that includes a lightweight, thin-walled aluminum stainless-steel liquid oxygen and methane-fueled booster. The Yanxinghe booster used within the check is 4.2 meters in diameter and 26.8 meters tall. In distinction, SpaceX’s Falcon-9 first stage booster utilized in restoration landings is 3.7 meters extensive, and 41 meters tall. The booster was constructed by the Jianyuan Expertise cooperation.

“The success of this flight restoration check is a serious breakthrough within the growth of liquid reusable rockets and has milestone significance.” says Sepoch and Jianyuan Expertise on WeChat. “It additionally marks that large-scale stainless-steel reusable launch automobiles have entered the engineering utility stage, laying a strong basis for this 12 months’s first flight of Yuanxinghe No. 1.”
House Epoch (typically abbreviated Sepoch) is a Bejieng-based house startup. A flurry of China-based startups have emerged lately, to incorporate Landspace, iSpace and Galactic Vitality. Landspace reached orbit on July 2023, and landed a booster with the check of the Zhuque-3 rocket on January 19^th^, 2024.
China versus SpaceX
The concept of touchdown and reusing boosters was pioneered by SpaceX, with the profitable first touchdown of a Falcon-9 stage one booster on December 21^st^. 2015. It is unusual to assume; SpaceX has turned this feat right into a close to each day routine incidence, with a U.S. launch almost each different day in 2025. Most of these have been Starlink batch launches, with 49 to this point for 2025.

Watching the spaceflight schedule worldwide, launches are actually primarily divided into three classes: China, SpaceX, and all others.
China’s Shanghai Spacecom Satellite tv for pc Expertise’s (SSST) is even at present fielding its personal reply to SpaceX’s Starlink, with the corporate’s 1,000 Sails mega-satellite constellation initiative began in late 2024.

House Epoch is seeking to obtain orbit with their Yuanxinghe rocket later this 12 months. This comes as China accomplished the launch of its first asteroid pattern retrieval mission final week, and continues a long run human presence in orbit with their Tiangong House Station. The company additionally plans to launch its personal model of Hubble the Xuntian house telescope in 2026 to station-keep with Tiangong. It is also not out of the realm of chance that China may full the primary Mars Pattern Return mission, with the launch of Tianwen-3 in 2028.
It is a busy 12 months in spaceflight, and it is going to be attention-grabbing to see House Epoch and different China-based startups take to orbit quickly.
