According to the report, the results for all technologies tested not only exceeded expectations but surpassed the previous records set by similar technologies in China.
Launched on Dec. 20, 2022, Tianqin-1 is a satellite for space-based gravitational wave detection. Its core task is to verify technologies, including high-precision inertial sensing, micro-Newton propulsion and drag-free control, said the report, citing Luo Jun, chief scientist of the detection project and an academician of the Chinese Academy of Sciences.
The results of the first round of tests for Chinas Tianqin-1 experimental satellite were published by the international journal Classical Gravity and Quantum Gravity, which showed encouraging results, the Peoples Daily reported Monday.
Gravitational waves are ripples in the bric of space-time caused by some of the most violent and energetic processes in the universe. Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity.
Meaning harp in the sky, the Tianqin project is expected to build a gravitational wave detection observatory in space, with three satellites in an orbit about 100,000 km from Earth to form an equilateral around 2035. When gravitational waves come, the harps strings will be plucked, according to scientists.
The observatory will be used for research in astronomy, cosmology and basic physics, the news said.
