Long March 2C rocket successfully launches Sino-French astronomical satellite…… On the occasion of the 60th anniversary of the establishment of diplomatic relations between China and France, at 15:00 on June 22, the Long March 2C carrier rocket, developed by the First Academy of China Aerospace Science and Technology Corporation, ignited and took off from the Xichang Satellite Launch Center, and then successfully sent the Sino-French astronomical satellite into the predetermined orbit. The launch mission was a complete success.


The Sino-French Astronomical Satellite is a space science satellite jointly demonstrated and developed by China and France. It is the satellite with the strongest multi-band comprehensive observation capability of gamma-ray bursts in the world to date, and will play an important role in scientific discoveries in the field of space astronomy such as gamma-ray burst research. The Xi’an Branch of the Fifth Academy of China Aerospace Science and Technology Corporation undertook the development task of the satellite’s data transmission subsystem.


This launch is the 525th launch of the Long March series of carrier rockets

The CATCH project of the Hunter Constellation for Tracking All-Variable Sources was proposed by the Institute of High Energy Physics of the Chinese Academy of Sciences. It aims to conduct multi-target, uninterrupted, and multi-parameter observations of massive variable sources. The CATCH-1 satellite is the first test satellite of the constellation. It is developed by the Microsatellite Innovation Institute of the Chinese Academy of Sciences. Its main task is to conduct in-orbit verification of space technologies such as lightweight X-ray focusing mirrors, silicon drift detector systems, remote sensing cameras, satellite rapid steering capabilities, high-precision extension mechanisms, and intelligent control. It also cooperates with the observation and early warning of the Sino-French astronomical satellite SVOM to quickly carry out opportunity observations and promote subsequent cooperation between China and France. This mission is the 56th satellite launch mission of the Microsatellite Innovation Institute of the Chinese Academy of Sciences. So far, it has successfully launched 105 satellites covering communications, navigation, remote sensing, science, micro-nano and other fields.

On the 22nd June 2024 schedule to launch  CNSA _China National Space Administration -China – People’s Republic of China 1500 Hours Hong Kong –Beijing Time China- People’s Republic of China…. at the Xichang Satellite Launch Center, Sichuan Province.

The Sino-French SVOM mission (Space-based Multi-band Astronomical Variable Object Monitor) is scheduled to be launched at 15:00 on June 22 at the Xichang Satellite Launch Center using a Long March 2C carrier rocket. The satellite’s target operating orbit is a low-Earth orbit with an inclination of 30 degrees and an altitude of 625 kilometers. The total weight of the satellite is 930 kg, and the payload weighs 450 kg.



The mission includes 4 main instruments, 2 of which are French (ECLAIR and MXT) and 2 are Chinese (GRM and VT):
– The ECLAIR telescope is used to detect and locate gamma-ray bursts in X-rays and low-energy gamma rays (from 4 to 250 keV).
– The MXT telescope (Microchannel X-ray Telescope) is used to observe gamma-ray bursts in high energy
– The VT telescope (Visible Light Telescope) operates in the visible light region and is used to detect and observe visible light emissions immediately after gamma-ray bursts.
The total weight of the satellite is 930 kg, and the payload is 450 kg. It will be placed in a low Earth orbit with an inclination of 30 degrees, an altitude of 625 km and an orbital period of 96 minutes.



Observations in space will be complemented by a large ground segment, which includes:
– A wide field camera GWAC (Ground-based Wide Angle Camera) for studies from the ground in the visible light region, detecting the prompt emission of part of the burst – A GFT (Ground Tracking
Telescope) robotic telescope to precisely measure the coordinates of the gamma-ray burst.
