Looking at the total lunar eclipse from a place far away from the earth 100 million km, it looks like this

The spacecraft ' Lucy ,' launched on October 16, 2021 for the purpose of investigating Trojan asteroids, is returning to Earth on October 16, 2022 to receive a swing-by gravity assist. NASA has released a video of Lucy observing a total lunar eclipse at a distance of about 100 million kilometers from the earth.

Unlike the sun, the asteroids that Lucy investigates do not emit light on their own and are extremely dark, so a camera with considerable sensitivity is required to shoot them. Therefore, Lucy is equipped with an ultra-sensitive camera called 'Eagle Eye' called ' L'LORRI '. L'LORRI uses the same Ritchey-Chrétian reflecting telescope as the Hubble Space Telescope, and it is possible to clearly see a crater with a diameter of 70 m from a distance of 1000 km. NASA says this resolution is equivalent to seeing flies perched from one end of the football field to the other.

Below is a picture of the total lunar eclipse taken with Lucy's ultra-sensitive camera.

#LunarEclipse last weekend? Our #LucyMission did, from 64 million miles from Earth!

The movie shot is a time-lapse movie that summarizes about 3 hours from 21:40 on May 15, 2022 to 0:30 on 16th in Eastern Standard Time in just 2 seconds. The earth is on the left and the moon is on the right.

When the moon entered the shadow of the earth and the total lunar eclipse began, the moon disappeared.

According to NASA, when viewed from Lucy, which is 100 million km away from the earth, the earth and the moon are only 0.2 degrees apart, which is 'the left and right tails attached to the car 400 m away. It seems that it looks as far as 'light'.
