(FOX NEWS) – NASA’s Curiosity rover is getting a firsthand look
at a region on Mars previously only seen from orbit that features
a "boxwork" pattern, along with evidence of ancient waterways,
including rivers, lakes and maybe an ocean.

New images and data from the Mars rover have already raised
questions about how the red planet’s surface was changing
billions of years ago.

Scientists are still unable, though, to answer why the planet’s
water eventually dried up and converted the surface into a chilly
desert.

Curiosity rover is in an area called Gale Crater, and evidence has
shown that when it was formed, water was percolating under the
surface.

NASA said the rover had found evidence of groundwater in the
crater when it encountered crisscrossing low ridges, some of
which were only a few inches tall and were described by
geologists as being arranged in a boxwork pattern.
