China’s reusable sub-orbital space carrier made its first successful repeated-use experiment flight on Friday, the developer China Aerospace Science and Technology Corp (CASC) announced. This is a great step forward of China’s development in reusable space transportation technologies, the corporation said.
The vehicle, a lifting-body sub-orbital carrier, was reused and launched vertically in the Jiuquan Satellite Launch Center in Northwest China’s Gansu Province after receiving inspection and maintenance, the China Central Television reported citing an announcement of the CASC.
It landed stably at an airport in Alxa Right Banner in North China’s Inner Mongolia Autonomous Region after finishing a flight in the sub-orbit as planned, according to the announcement.
Song Zhongping, a space analyst and TV commentator, told the Global Times that sub-orbital carriers, which are used for sending payloads to about 100 kilometers above the Earth’s surface, could serve a variety of purposes such as ferrying satellites.
The lifting-body and sub-orbital characteristics mean that the carrier has aerodynamic design and can conduct operation in sub-orbit. Such craft has more lifting power, Song explained.
Technologies required for reusable sub-orbital flights are very demanding, as the craft had experienced both the environment in space and that under the Earth’s atmospheric influence, experts said.
The latest successful repeated-use flight means that both materials and engine system of China’s domestic reusable sub-orbital vehicle can be reused, which is a great technical breakthrough and remarks a technical milestone, Song said.
One of the most noteworthy points of the flight is that the carrier landed in a normal airport, which is more practical and safer, just like US’ space plane. China’s mastery of such technologies will greatly boost the research into space planes, laying a solid foundation for developing one of our own space planes in the future, Song said.
CASC’s reusable sub-orbital carrier made its successful maiden flight in July. The development is an advanced integration of aerospace and aviation technologies, and “indicates China’s transition from a big space-faring nation to a strong one,” CASC said at that time.
It had laid a solid foundation for reusable space-Earth transportation technology, representing the country’s first step to achieve innovative, independent development in this field, CASC said.
Reusable sub-orbital vehicles are of huge commercial relevance in the future. They can be developed into carriers for space tourism, fast intercontinental personnel and cargo transport, Wang Yanan, chief editor of Beijing-based Aerospace Knowledge magazine, told the Global Times on Friday.
The vehicles can also be used in taikonauts training, according to Wang.
China’s commercial space industry has begun burgeoning since 2014 when the nation opened up the space sector to private capital.
In a statement the CASC provided to the Global Times, the CASC said that it was working on a series of reusable space launch and transport systems, which will greatly boost the country’s space shuttle capability, lowering costs and empowering future development in this domain.
However, China’s focus and achievements on aerospace exploration has been slandered by some Western countries as a “threat” as they incorrectly described such achievement is out of military purposes. For example, a report published in July by US magazine The National Interest demonized China’s achievements in space by interpreting China’s space exploration missions, including the lunar program and manned spaceflight, as “threats to US leadership in space” and a “detriment to US national security.”
But facts show that the US is the biggest threat in space with its space hegemony based on its technological advantages. Meanwhile, China sees space as a new field to expand international cooperation while sharing its achievements with other countries by providing them with opportunities to make use of space resources.
It was clearly stated in the “China’s Space Program: A 2021 Perspective” white paper released in January 2022 by the State Council Information Office that China has always advocated the use of outer space for peaceful purposes and opposes any attempt to turn outer space into a weapon or battlefield or start an arms race in outer space. China develops and uses space resources in a prudent manner, takes effective measures to protect the space environment, ensures that space remains peaceful and clean and guarantees that its space activities benefit humanity.
