The red, yellow and green planet: Strange traffic light-shaped rock spotted on Mars


comments

Mars is a weird and wonderful world of odd rocks that formed long ago in the planet's history.

And this latest image is no exception, as the Curiosity rover has spotted what looks like a bizarre set of 'traffic lights' on the surface.

Of course, the discovery is nothing more than a chance alignment of rocks and shapes - but it highlights just how interesting the Martian surface is.

In the image, a set of three large rocks - admittedly with a larger fourth one as well - are stacked on top of each other.

CURIOSITY BY NUMBERS 

The rover's top speed is 1.5 inches (3.8 centimetres) per second.

Curiosity is the fourth rover to visit Mars.

It took around seven minutes to land on the Red Planet.

The rover is fitted with 17 cameras.

It weighs about the same as a Mini Cooper at approximately 900kg (2,000lbs).

Scientists considered 60 possible landing sites before deciding on Gale Crater. 

They bear a striking resemblance to traffic lights on Earth.

But it's highly unlikely this same feature was built by a martian civilisation. 

The image was shot from the six-foot (1.8 metre) high, left-hand side mast cam on the Curiosity Rover.

It was the 753rd day the rover has been exploring the red planet.

The rock was spotted in the image by space video journalist Joe Smith from Bristol who runs a YouTube channel called ArtAlienTV.

'I saw this one and I thought "hang on, that looks a bit strange". I think it looks like a traffic light.

'It is hard to tell how big it would be without any point of reference, but I would estimate it was about 12 inches [30.5cm].

'I posted it on the internet and people said they thought it looked like a set of traffic lights too - although some people did say it looked like a totem pole.'

The latest image from Curiosity is just one of many fascinating rocks on the red planet that resembles something we are familiar with on Earth

Just days earlier, Curiosity had spotted a ball-shaped rock on the surface of Mars.

Nasa said it was likely an example of Martian concretion, the process of compacting and hardening a mass of matter, according to Discovery News.

Curiosity is currently at the base of Mount Sharp, which has been the target for the mission since it landed just over two years ago.

The area is geologically fascinating as it contains layers that may provide an insight into the history of Mars.

And, scientists hope the region might reveal how and why Mars lost what was once thought to be a habitable environment, with water flowing on its surface.

This, in turn, may provide answers on the future of Earth.

The discovery follows another intriguing image that showed an almost perfectly round rock on the Martian surface (shown). Nasa said it was likely an example of Martian concretion, the process of compacting and hardening a mass of matter
