resolution of the issue may be that Gaspra obtained a regolith during the Flora-family forming impact that also created Gaspra itself. Secondly, it has been estimated that the matter ejected by all the craters would be only enough to cover Gaspra with 10 m of regolith. However, some craters are much deeper than this without showing any structural difference on their walls.
684:
Grooves about 100 m (330 ft) to 300 m (980 ft) wide, up to 2.5 km (1.6 mi) long, and tens of meters deep are seen on Gaspra's surface, which may be related to Gaspra's formation along with the rest of the Flora family in an asteroid collision. Their presence also suggest

Apart from a multitude of small craters, Gaspra has half a dozen large flat areas and concavities. One of these flat areas, Dunne Regio, is a 5 km × 7 km (3.1 mi × 4.3 mi) area that is flat to within 200 m (660 ft). It is uncertain whether these are the result

The extensiveness of regolith on Gaspra and its presence overall is a matter of debate, and not fully understood. Visually, the somewhat subdued and mantled appearance suggests a substantial regolith. Also, correlations are seen between the subtle color variations and local topography, and it has

and Gaspra was relatively recent on an astronomical timescale, so that Gaspra has not yet had the opportunity to acquire many large craters since. Analysis of cratering rates suggests the age of the surface is between about 20 to 300 million years. It was suggested in 2007 that the fresh, steep
