(WP:NFCC#1)
The probe was destroyed shortly after this image was taken, therefore the image cannot be replaced. Short of sending another probe to the Martian moon, it would be next to impossible to recreate this image.
Minimal use (WP:NFCC#3) Low resolution image, one image only used in the article.
Respect for
commercial opportunities
(WP:NFCC#2)
The image is widely distributed on websites, in books and on television. A low resolution image posted on Wikipedia for educational purposes does not harm any commercial opportunities of the Russian Space Research Institute, who have also posted the images for all to see on a freely accessible website as shown in the link above.
