Mysteriöser Krater auf dem Mars hat mehr als zwei Milliarden Sekundärkrater German
jordanlund, 
Took a couple of tries for the translation to work:
“Mysterious crater on Mars has more than two billion secondary craters
The Corinto crater on Mars is only two million years old. When it was formed, well over a billion other craters were created.”
The ejecta from the primary impact created a billion smaller craters.
