Four days later, Apollo 11 commander Neil Armstrong stepped out of the lunar module and took "one small step" in the Sea of Tranquility, calling it"a giant leap for mankind."

阿姆斯特朗走出登月舱并迈出了历史性的"一小步"，也是"人类的一大步"。

While astronauts Armstrong and Aldrin explored the Sea of Tranquility region of the moon, astronaut Michael Collin remained with the command and service modules in lunar orbit.

当宇航员阿姆斯特朗和奥尔德林在月球的静海地区探索的时候，留在指挥服务舱的宇航员迈克尔·科林仍在绕月球轨道飞行。

Commander Neil Armstrong, the first on the moon, captured this image—one of the most famous photographs of the 20th century—soon after the lunar lander Eagle touched down in the Sea of Tranquility.

指挥官阿姆斯特朗首先登月，拍摄了这张照片-20世纪最著名的照片之一。稍后小鹰号登月舱在静海着陆。

The zenith of that project was 40 years ago today on July 20th 1969,when Neil Armstrong stepped out of Apollo 11's lunar module onto the Sea of Tranquility ,and promptly fluffed his lines .

当时尼尔-阿姆斯特朗走出阿波罗的探月舱踏上静海，却忘了他的台词。

It will also send information on the traces of the composition of the lunar surface apart from looking for atomic minerals such as thorium and uranium.

So cooperative controlling of driving force of wheel is a key of trafficability on tough lunar terrain.Based on SQP algorithm,driving force of wheel was optimized. Optimization is based on restriction of moving safely and smoothly.The aim of optimization is to minimize power consume of motors and varying range of driving force.

本文基于序列二次规划算法优化摇杆-转向架式月球车车轮系统驱动力输出，建立保证月球车在月壤平稳安全通过的力学约束方程，以车轮驱动功率和驱动力变化最小为目标函数优化车轮驱动力输出，使月球车平稳前进的同时车轮驱动电机功率消耗最小，这对能源有限的月球车来说是很有意义的。

At maximum eclipse, the umbra covered only about 8 percent of the diameter of the lunar disk.

食甚阶段，本影约覆盖了月盘直径的百分之八。

This immediately brings us to the next part of this article: creating an output "replace function".
