Check out this photo. The rock in the center frame is Phobos, one of Mars' moons. The photo is curtsey of the Mars Express orbiter, skimming the surface at a mere 28 miles!
Why? Well the ten year old orbiter was helping scientists to determine the density of the moon. One unfortunate thing is, no cameras were in use at the time because of the orbiter's orientation, but this week it did make a 300 mile pass which did have cameras pointed at the moon.
If you think the photo here is spectacular, take note.....it was taken at over 4000 miles. Yes, we are going to have some spectacular results once the data is transmitted to Earth.
