## 阿尔忒弥斯2号分享首张地球图像 美国宇航局阿尔忒弥斯2号的宇航员们发布了令人惊叹的高分辨率地球图像，他们正前往月球——自1972年以来，人类首次旅行到地球轨道之外。指挥官里德·维斯曼在一次成功的引擎燃烧推动猎户座飞船进入超过20万英里的轨道后，拍摄了这些照片。 这些图像展示了大西洋、极光，甚至金星，从他们的视角来看，地球显得“上下颠倒”。一张引人注目的照片突出了白天和黑夜之间的分界线，被称为分界线。 最初，由于距离问题，曝光设置对维斯曼和船员提出了挑战，他们迅速适应，并热情地记录了他们的视野。他们甚至要求提供窗户清洁用品！ 阿尔忒弥斯2号将于4月6日绕月球背面飞行，并于4月10日返回地球。这项任务是美国宇航局到2028年再次将人类送上月球的关键一步。

阿耳忒弥斯2号宇航员拍摄的一张令人惊叹的地球照片正在Hacker News上引发讨论。这张照片显示被月光照亮的地球夜侧，最初让一些观众感到困惑，误以为是白天景象。 用户分享了来自NASA网站的高分辨率版本链接，并指出它们之间存在亮度差异。讨论很快偏离了主题，并如预料般吸引了地平论者的评论，其他用户建议忽略这些评论。 一场更具哲学性的辩论浮出水面，讨论了对关于遥远、不可观测现象的科学主张的接受程度，一位用户认为，用“地平论者”来驳斥怀疑论是一种压制对缺乏充分证据的非凡主张的合理质疑的策略。其他人则为既定的科学方法和教育进行了辩护。

Artemis II crew take 'spectacular' image of Earth

Nasa has shared the first high-resolution images of the Earth taken by the Artemis II crew as they head on their trip around the Moon.

The mission's commander, Reid Wiseman, took the "spectacular" images, Nasa says, after the crew completed a final engine burn that set them on a trajectory towards our closest celestial neighbour.

The first image, called Hello, World, shows the vast expanse of blue that is the Atlantic Ocean, framed by a thin glow of the atmosphere as the Earth eclipses the Sun and green auroras at either pole.

The Earth appears to us as upside down, with the western Sahara and Iberian peninsula visible to the left and the eastern portion of South America to the right.

Nasa identified the bright planet to the bottom right as Venus.

The images were taken after the crew successfully completed a trans-lunar injection burn in the early hours of Friday.

The burn took the Orion spacecraft out of Earth orbit as the four astronauts aboard aim to travel the more than 200,000 miles to the Moon.

Artemis II is now on a looping path that will carry the crew around the far side of the Moon and back again. It is the first time since 1972 that humans have travelled outside of the Earth's orbit.

The crew should pass around the far side of the Moon on 6 April and return to Earth on 10 April.

After the burn was completed, the crew were "glued to the windows" taking pictures, mission specialist Jeremy Hansen told mission control in Houston.

"We are getting a beautiful view of the dark side of the Earth, lit by the Moon," he said.

Wiseman later called back down to mission control in Houston to ask how to clean the windows, as the astronauts' enthusiasm to see into space had left them dirty.

The commander had initially found it difficult to take pictures of our planet from the spacecraft, saying taking photos at such a distance made it hard to adjust exposure settings.

"It's like walking out back at your house, trying to take a picture of the moon," he told mission control. "That's what it feels like right now."

But that is no longer an issue.

Another view captured by Wiseman shows the Earth divided by night and day. That frontier between light and darkness is known as the terminator.
