Spiky Mars Rocks Were  and Ancient Fractures

Likely Formed by Erosion

The Curiosity rover spotted

 the sinewy rocks on May 15, according to raw images the mission sends down to Earth.

The spikes are

 most likely the cemented fillings of ancient fractures in a sedimentary rock

The delicate features may also

 have been shaped by the planet’s lighter gravity, which is about one-third of what we experience on Earth

On sols 3473 and 3475,

 Curiosity was working at a location on Mount Sharp (Aeolis Mons) nicknamed Mirador Butte

There will be a mosaic on

 the hill just off at a distance, now called ‘Sierra Maigualida,’ which will tell us more about the textures

The rover was also expected to

 examine “interesting structures” on a target nicknamed “La Paragua,” to do multispectral analysis on a second target called “San Pedro,”
