For the past two and a half years, the Curiosity Rover has been trekking across the surface of Mars, searching for clues as to what the planet looked like many eons ago. In addition to drilling, scanning, and occasionally taking breathtaking photos, it has also been monitoring data on the planet’s limited atmosphere, hoping to learn more about its composition and surface temperatures.
And according to the latest data obtained by the rover and processed by the Mars Science Laboratory (MSL), temperatures in the Gale Crater can reach a daytime high of -8 °C (17.6 °F). Meanwhile, here on Earth, cities in the northern US like Chicago and Buffalo were experiencing temperatures in the vicinity of -16 to -20 °C (2 to -4 °F). This means that, some parts of the United States are presently experiencing temperatures that are colder than on Mars!
