暗黑模式开启！

As NASA prepares to send astronauts to the Moon’s South Pole under Artemis, divers at the Neutral Buoyancy Laboratory (NBL) in Houston are setting the stage for future moonwalk training by simulating lunar lighting conditions. At the Moon’s South Pole, the Sun will remain no more than a few degrees above the horizon, resulting in extremely long and dark shadows. To prepare astronauts for these challenging lighting conditions, the team at the NBL has begun preliminary evaluations of lunar lighting solutions at the bottom of the 40-foot deep pool. This testing and evaluation involved turning off all the lights in the facility, installing black curtains on the pool walls to minimize reflections, and using a powerful underwater cinematic lamp, to get the conditions just right ahead of upcoming training for astronauts.

随着NASA准备在阿耳忒弥斯的带领下将宇航员送往月球南极，休斯顿中性浮力实验室（NBL）的潜水员正在通过模拟月球照明条件为未来的月球行走训练奠定基础。太阳将保持在地平线上方不超过几度的位置，从而产生极长而黑暗的阴影。为了让宇航员为这些具有挑战性的照明条件做好准备，NBL的团队已经开始对40英尺深的水池底部的月球照明解决方案进行初步评估。这项测试和评估包括关闭设施中的所有灯，在泳池墙壁上安装黑色窗帘以减少反射，并使用强大的水下电影灯，为即将到来的宇航员训练做好准备。
