Tianwen-2 probe reaches asteroid 2016HO3 for scientific exploration

By PulseAugur Editorial · [1 sources] ·

The Tianwen-2 probe has successfully reached its target asteroid, 2016HO3, after a journey of approximately 400 days and covering about 1 billion kilometers. The probe is now in orbit around the asteroid, about 20 kilometers away, and has begun its scientific exploration, capturing imagery and refining the asteroid's positional data. This mission, launched from the Xichang Satellite Launch Center, significantly improved the accuracy of 2016HO3's location from hundreds of kilometers to just a few. AI

    Tianwen-2 Arrives at Target Asteroid to Conduct Scientific Exploration

    从国家航天局获悉，天问二号探测器历经约400天、行程约10亿千米的“追星”之旅，于近日与小行星2016HO3成功交会，到达距离小行星20千米处，开始科学探测。在抵近小行星过程中，探测器获得小行星影像数据。同时，任务团队利用探测器抵近过程中获得的光学导航数据，改进了小行星星历，将之前仅依靠地基观测所确定的小行星位置误差，由上百千米减小到千米量级。探测器于2025年5月29日，在西昌卫星发射中心成功发射。（新华社）
