China Launches Sino-French Satellite to Study Gamma-Ray Bursts

China successfully launched the Space-based Multi-band Variable Object Monitor (SVOM) on Saturday, marking nearly 20 years of collaboration with French scientists. The satellite, designed to capture gamma-ray bursts, was sent into orbit by a Long March-2C rocket from the Xichang Satellite Launch Center in Sichuan Province. Gamma-ray bursts are short, violent phenomena occurring during the collapse of massive stars or the merging of binary stars, providing crucial insights into cosmic evolution.

SVOM's main scientific objectives include rapidly locating various gamma-ray bursts, comprehensively measuring their electromagnetic radiation properties, and studying the evolution of the universe through these bursts. Additionally, the satellite will observe electromagnetic signals associated with gravitational waves. Wei Jianyan, SVOM's Chinese principal investigator, emphasized the potential for significant discoveries, such as identifying gamma-ray bursts from the early universe, which will aid in understanding cosmic evolution.

The satellite is equipped with four scientific instruments, two developed by China and two by France, allowing for a large field of view and high-precision observation. Bertrand Cordier, the French principal investigator, highlighted the importance of using gamma-ray bursts to observe the early universe, potentially revealing the first stars. This joint mission underscores the importance of international collaboration in advancing astronomical research.
