东方红一号卫星---可旋转展开

1970年4月24日中国发射的第一颗人造卫星。东方红一号卫星工作28天（设计寿命20天）。卫星于5月14日停止发射信号，但是截至2024年，东方红一号卫星仍在空间轨道上运行 。

The first artificial satellite launched by China on April 24, 1970. The Dongfanghong-1 satellite will operate for 28 days (with a designed lifespan of 20 days). The satellite stopped transmitting signals on May 14th, but as of 2024, the Dongfanghong-1 satellite is still operating in space orbit.

本模型可以旋转后在离心力的作用下展开天线，打印精度不够的建议分体打印顶部天线。全模型无需支撑。

This model can rotate and expand the antenna under the action of centrifugal force. For those with insufficient printing accuracy, it is recommended to print the top antenna separately. The entire model does not require support.
