Фобос и Деймос в сверхнатуральную величину
Попалась забавная подборочка фотографий спутников Марса. Советую посмотреть.

The giant Stickney crater on Phobos is clearly visible on this Viking image.
One of the most striking features on the 27 km diameter, irregularly shaped
Phobos is the presence of grooves over most of its surface. The grooves seem
to radiate in all directions from the giant Stickney crater (left) and
converge on the opposite side of the satellite at a region close to the
Stickney antipode. The grooves are best developed near Stickney, where some
measure 700 m across and 90 m deep. However, most of the grooves have widths
and depths in the 100 - 200 m and 10 - 20 m ranges, respectively.

Deimos, the companion moon of Phobos, was also imaged by the Viking Orbiter.
This computer mosaic of Deimos was made with images acquired from the Viking
Orbiter during one of its close approaches to the moon. The 15 km diameter
Deimos circles Mars every 30 hours. Scientists speculate that Deimos and its
companion moon Phobos were once passing asteroids that were pulled in by the
gravity of Mars.

One of the highest resolution images to date of Phobos obtained with the Mars
Orbiter Camera. This image of Phobos was taken with the Mars Orbiter camera
on the Mars Global Surveyor (MGS) on August 19, 1998, 10 AM PDT. The MGS
spacecraft was approximately 1080 km from Phobos at closest approach. This
image, about 8.2 km wide by 12 km tall, shows the full field-of-view of the
Mars Orbiter Camera (MOC) as spacecraft motion swept across the satellite.
The image as shown here has a scale of 12 m per picture element. Credit:
