A nave Deep Impact foi aquela que se chocou com um cometa para investigar do
que ele era feito. Depois do impacto, a nave seguiu viajando pelo espaço,
sendo usada para diversas outras observações. Em maio de 2008 ela apontou
suas câmeras para a Terra por várias horas e teve a oportunidade de
documentar a passagem da Lua exatamente em frente ao nosso planeta. Clique
no link abaixo e veja dois pequenos vídeos do YouTube mostrando essa
passagem.

"First, the setup. The Deep Impact spacecraft was the one that smacked a
chunk of copper into a comet so that we could see what materials were
below the surface. After the impact, the spacecraft kept going (with the
mission renamed EPOXI), and it's being used to do all sorts of
interesting observations.

In late May, 2008, it turned its cameras back to Earth and observed us
over the course of a several hours. During this time, from EPOXI's point
of view, the Moon passed directly in front of the Earth! The images were
put together (by my old boss, Don Lindler!) into, well, one of the most
astonishing animations I have ever watched. Ever."
