On the 9th January 2024 in CNSA _China National Space Administration -China – People’s Republic of China 1503 hours Hong Kong –Beijing Time China- People’s Republic of China launch the Chang Zheng – Long march 2C Carrier Rocket launching from station form Xichang Satellite Launch Center Sichuan Province….. In which中国 successfully launched the 2C carrier rocket ignited and took off from the Xichang Satellite Launch Center, and then successfully sent the Einstein probe satellite into the predetermined orbit. The first mission of the Chang-II C rocket in 2024 was a complete success. This mission also means that China Aerospace Science and Technology Corporation has won its first victory in the 2024 space launch mission.
The Chang Zheng – Long March 2C carrier rocket at the Xichang Satellite Launch Center to successfully launch the Einstein Probe satellite. space, the satellite successfully entered the scheduled orbit, and the launch mission was a complete success. The Einstein probe satellite is the first large-scale application of “lobster eye” microhole array focusing imaging technology in the world, which can achieve a 10-fold improvement in sensitivity and spatial resolution. It can accurately capture the universe while conducting large-field monitoring. We will detect more distant and faint high-energy temporary sources and fleeting unknown phenomena, and issue early warnings to guide other astronomical equipment based on space and ground to conduct follow-up observations. Thumbs up!!!
Einstein probe According to reports, the Einstein probe satellite is a catcher of explosions of cosmic objects. It can accurately capture more distant and faint temporary sources and explosive objects, and explore X-ray signals from gravitational wave sources. , is of great scientific significance for studying stellar activity, the formation, evolution, merger and other processes of compact objects such as black holes and neutron stars.
The Einstein probe satellite uses astronomical time-domain observation methods in the soft physical process. The Einstein probe satellite carries two payloads: the Widefield X-ray Telescope (WXT) and the Follow-up X-ray Telescope (FXT). For the first time in the world, the “lobster eye” microhole array focusing imaging technology is used on a large scale. The detection capability is world-leading, and the sensitivity and spatial resolution can be improved by 1 to 2 orders of magnitude. While detecting a large field of view, it can accurately detect Capture distant and faint high-energy temporary sources and fleeting unknown phenomena in the universe, and issue early warnings to guide other astronomical equipment based on space and ground to conduct subsequent observations. The satellite design life is 5 years
“The Einstein probe satellite launched this time is one of the space science satellites established and implemented under my country’s Space Science Pilot Project (Phase II). It is also my country’s first large-field X-ray astronomy satellite, used to capture Einstein’s predictions. astronomical phenomena such as black holes and gravitational wave electromagnetic counterparts.” At the mobilization meeting, Cui Zhaoyun emphasized the importance of this mission to the team members.
This mission involves the “Princess and the Pea” who cannot tolerate a speck of dust. Several high-end cameras were installed on this payload, and the lenses had very high requirements for cleanliness. To this end, the operators also performed “dust-proof treatment” on the inner wall of the long 2-propylene rocket fairing.
The fairing usually consists of a basic structure with a composite skin and metal reinforcements. After being fixed with rivets, there will be very small debris in the gaps in the inner wall. These debris may fall onto the lens during fairing closure or flight vibrations. “General loads will not be affected by this, but considering the particularity of this mission, we sprayed a layer of coating on the inner wall of the fairing to seal in fine dust.”
