NASA's Curiosity rover has been roaming the Red Planet since 2012, taking thousands of pictures, drilling small holes in the planet's surface and searching for evidence of past habitable environments on Mars. It has also been busy observing the weather.
Curiosity is outfitted with a miniature weather station that measures temperature, humidity, winds, pressure and ultraviolet radiation. These observations are sent back to Earth on a regular basis, and they help scientists understand the alien weather on the desolate world.
On May 12, the high temperature was 11 degrees below zero, and the low temperature was a staggering 114 degrees below zero.

It is currently late autumn in Gale Crater, the region of Mars where Curiosity is exploring, meaning even colder weather is ahead for the rover in the coming months.
