See NASA's Curiosity rover dig like a dog in the Mars sand

The rover isn't burying treasure, but it still looks like it's having a lot of fun.

This impressive wheel mark is part of Curiosity's science mission on Mars.


It doesn't matter if you're a machine on a distant planet. Sometimes you just feel compelled to play in the sand.

NASA's  Curiosity rover created this beautiful wheel track on Oct. 14. The rover can't make sand castles, but it can use its wheels in the pursuit of planetary exploration.

"Yestersol's drive purposely ran over a megaripple (fine grained sandy ripple with a coarser pebble coating) to create a 'scuff' which churned up and bisected the feature to observe any layering or material within," wrote NASA planetary geologist Fred Calef in a Curiosity mission blog update this week.

A Twitter user tweeted a GIF showing the wheel in action, like it's planning to bury a bone in that spot.

Mars fans are familiar with a lot of the rover's behaviors, including drilling, selfies and close-up camera examinations of interesting objects. Scuffing the ground is a rarer move. This action is done "very intentionally and carefully," said Curiosity team member Keri Bean on Twitter  

Curiosity is taking a closer look at both the disturbed ground and the sand around it. The rover will also investigate the chemical makeup of this spot and take snapshots of its surroundings. 

The rover's aluminum wheels have taken a beating on the rocky Red Planet, but they're holding up. This successful scuff is a testament to the strength of the wheels and the rover team's ability to delicately control a machine so far away on Mars.
