NASA astronauts aboard the International Space Station wear eclipse glasses in this image from March 26, 2024. While millions of people on Earth experience the total solar eclipse on April 8, 2024, the space station crew will have the opportunity to see it from 250 miles above our planet. Except during the brief period when the Moon completely blocks the Sun’s bright face, it is not safe to look directly at the Sun without specialized eye protection for solar viewing. On Earth, you must look through safe solar viewing glasses (“eclipse glasses”) with the ISO 12312-2 international standard or a safe handheld solar viewer at all times. If the crew has the opportunity to directly image the eclipse through space station windows, they will use a handheld camera equipped with a solar filter and will not look at the Sun directly.
Based on current orbital position and ground track predictions for the International Space Station, astronauts aboard the orbiting laboratory will have three opportunities to view the ground shadow (penumbra and umbra) of the Moon as it tracks across the Earth surface during the total solar eclipse. After encountering the eclipse shadow above the Pacific Ocean, then during a pass from the New Zealand area to California and Idaho, the space station is predicted to encounter the eclipse during a time of near-to-full totality while over Maine and New Brunswick around 3:30 p.m. EDT.
For those who won’t be in the path of totality or on the space station, NASA will have live coverage of the eclipse.

这张照片摄于2024年3月26日，国际空间站上的NASA宇航员戴着日食眼镜。2024年4月8日，数百万人将在地球上目睹日全食，而空间站的机组人员将有机会在地球上空250英里处看到日全食。除了在月球完全遮挡太阳明亮的表面的短暂时期外，如果没有专门的眼睛保护装置，直视太阳是不安全的。在地球上，你必须始终通过符合ISO 12312-2国际标准的安全太阳观测眼镜（“日食眼镜”）或安全的手持太阳观测器来观测太阳。如果机组人员有机会通过空间站的窗户直接拍摄日食，他们将使用配备太阳滤镜的手持相机，而不是直接对着太阳拍摄。
根据国际空间站目前的轨道位置和地面轨道预测，轨道实验室的宇航员将有三次机会看到月球在日全食期间穿过地球表面时的地面阴影(半影和本影)。在太平洋上空遭遇日食阴影之后，空间站在从新西兰地区前往加州和爱达荷州的过程中，预计空间站将在美国东部时间下午3:30左右，在缅因州和新不伦瑞克上空遇到日全食。
对于那些不在日全食路径上或空间站上的人，NASA将对日食进行现场直播。
