As millions of people observed the total lunar eclipse on October 8, 2014, MESSENGER was also watching. From Mercury, the Earth and Moon normally appear as if they were two very bright stars. During a lunar eclipse, the Moon seems to disappear during its passage through the Earth's shadow, as shown in the two frames above.
MESSENGER was 107 million kilometers (66 million miles) from the Earth at the time of the lunar eclipse. The Earth is about 5 pixels across and the Moon is just over 1 pixel across in the field of view of the NAC, with about 40 pixels distance between them. The images are zoomed by a factor of two and the Moon's brightness has been increased by a factor of about 25 to show its disappearance more clearly.
