The first Chinese solar probe, the new generation manned rocket for lunar explorations and a super heavy launcher will be in the spotlight during the highly anticipated China Airshow which will take place from September 28 to October 3 in Zhuhai, in Guangdong (south of China). Province. The event not only showcases the country’s latest aerospace achievements, but also holds a number of surprises showcasing China’s most advanced space technologies.
Showcasing China’s ambition to explore the sun in the near future, the country’s first solar probe, developed by the Shanghai Academy of Spaceflight Technology under the leadership of the China Aerospace Science and Technology Corporation (CASC), will make its first public appearance at the event before its launch shortly thereafter.
One of the main scientific payloads on board the satellite is the H-alpha solar imaging spectrometer which will be the first in the world to be able to perform spectral imaging observations of the H-alpha band of the sun.
Changes in atmospheric temperature, velocity and other physical factors during the solar flare can be obtained through the analysis of spectral line data, providing key data for studies on the dynamics of the flare process. solar.
The birth of this satellite will greatly enhance China’s international influence in solar physics, observers noted.
The extra-large heavyweight launcher, which could be named Long March-9, is also expected to make its maiden flight around 2028.
The rocket was developed to be the most powerful member of the Chinese launcher family designated to perform manned lunar probe missions, among other deep space exploration missions, the Chinese Academy of Vehicle Technology said. launch (CALT).
The rocket, with a diameter of 9.5 meters and equipped with four boosters of 5 meters in diameter each, can launch payloads of up to 140 tons in the new Earth orbit, 50 tons in the lunar transit orbit and 35 tons in the transit orbit of Mars.
A new generation carrier rocket specially designed for future manned space flights to the Moon is another highlight of the exhibition on the Chinese rocket family.
The 90-meter-long rocket weighing around 2,000 tonnes at launch is capable of sending a 25-tonne payload directly into lunar transit orbit or a 70-tonne payload into near-Earth orbit.
It can also combine with multiple modules to accommodate a flow of rocket types that can carry payloads of 40 to 70 tonnes in low earth orbit or 10 to 32 tonnes in geostationary transfer orbit. It can also be reused during vertical takeoff and landing when using multiple engines in parallel configuration.
In addition to the launcher, the reentry module of a new generation manned test vessel will also be on display. It survived extreme heat of up to 3,000 Â° C upon re-entry on its successful maiden flight in May of last year, making it possible to verify key technical indicators for future lunar landings with a global level. .
