1. What was discovered on Mars?

Another image from MRO taken in 2014 shows an island in the shape of waffles. It is 1.2-miles wide and is located in an area of lava flows.

This lava could be causing the unusual sight but pushing the formation upwards.

10. Dragon Scales

NASA called these scaly patterns Dragon Scales of Mars. They are thought to be a result of erosion of ancient rocks over time though the exact process is still unknown.

This involves factors such as the nature of the water. The image was taken in July 2017.

11. Egg Rock

An iron meteorite, now called egg rock, was discovered in October 2016 by NASA's Curiosity rover. It is at the base of Mount Sharp in the Gale crater on Mars. 

The rock is quite tiny but can be studied in close-up views.

12. Scratch marks

Do you think the dragon scales were weird? MRO found these lines on the Martian surface in 2017. These lines that look like scratch marks are linear gullies caused by dry ice sliding down the slope.
