The braking is a key and risky step in the Mars exploration mission, which requires a high degree of accuracy. Only when the braking is performed with precise timing and duration can the probe successfully enter the planet's orbit.
BEIJING, Feb. 11 -- Precise braking near Mars has helped China's probe Tianwen-1 successfully enter the orbit around the red planet on Wednesday, according to the country's space scientists.
Yang Yuguang, a researcher with China Aerospace Science and Industry Corporation Limited, told the Science and Technology Daily that the braking is a key and risky step in the Mars exploration mission, which requires a high degree of accuracy.
