Earth isn’t the only planet to have had seasons study shows

My favorite part of where I live now is four distinct seasons each year. Wisconsin brings cold winters, hot summers, beautiful falls, and well, rainy springs. In contrast, during my time in Florida, we experienced two seasons: intensely hot and wet, followed by relatively less hot and dry (if you’re curious, the latter is when you most likely came for vacation). Interestingly, seasons appear to have lost their uniqueness in space, as a study indicates that Mars once possessed them before its water reserves evaporated.

The curious case of Curiosity’s cracked wheels

For any given Mars rover, there are three major and newsworthy events in its life: launch, landing, and discovery. Aside from those times, hardly anyone is paying attention to the myriad of images being sent back on a non-stop basis. Only the most hardcore Mars nerds or those who operate the rovers will see them. Or, anyone who follows a Twitter bot that automatically tweets the pictures. It’s thanks to this bot that word is getting out about Curiosity’s cracked wheels.
