Just look at that! During the Solar Eclipse last Sunday (03 Nov) the cubesat known as AeroCube-4 took this image of the moon’s shadow on Earth.
I was immediately struck by the great example of the umbral (darkest) and penumbral (shaded around the darkest area) areas. Excellent.
According to the Aerospace Corporation:
AeroCube-4 was west of the moon shadow, flying in a northeasterly direction. The view in the photo is toward the southeast, with part of the West African mainland visible at the top of the image.
I really like these cubesats! Read whole description at the Aerospace Corporation website.by
