Lunar eclipse as seen from space


A montage of pictures from Oct. 28, 2004, shows Earth and the moon during a total lunar eclipse, as seen by the AMIE camera on Europe’s SMART-1 spacecraft. The relative sizes of the two celestial bodies reflect what SMART-1 saw from a distance of 180,000 miles from Earth and 410,000 miles from the moon.

Half the world will be able to see a total lunar eclipse this week — but nobody will have the vantage point that Europe’s SMART-1 spacecraft had six years ago when it witnessed a similar event from deep space.

Lunar eclipses occur when Earth gets directly between the sun and the moon, covering up the face of the full moon with its shadow. On Oct. 28, 2004, SMART-1’s AMIE camera captured a series of images showing the shadow’s movement across the moon, as well as Earth’s sunlit side. The 3-foot-wide spacecraft was at the far end of its widely looping orbit around the moon — 410,000 miles from the moon and 180,000 miles from Earth.

The sizes of Earth and the moon in these pictures reflect the relative sizes that SMART-1 saw, but the two celestial bodies couldn’t be seen in the same frame. This montage combines shots that were taken separately.

Although no one will be watching this week’s eclipse from deep space, the crew aboard the International Space Station should get a good view from low Earth orbit. And millions can see the event from Earth. North Americans will have the best seats in the house. The shadow starts its passage at around 12:30 a.m. ET Tuesday, and the total eclipse reaches its peak at 3:17 a.m. ET Tuesday.
