Hello, I'm a space enthusiast with a keen interest in planetary science. Let's dive into the question of whether it can rain on Mars.

Mars has a very thin atmosphere, which is about 100 times less dense than Earth's. This thin atmosphere is composed mostly of carbon dioxide, with very little water vapor. The average temperature on Mars is also quite low, around -80 degrees Fahrenheit (-60 degrees Celsius), which is below the freezing point of water. However, there are conditions under which water ice can form in the Martian atmosphere.

There is no rain on Mars because the low temperatures and pressures mean water can only exist as vapor or ice (although it may have have rained in the geologic past say scientists). Snow occasionally forms in the upper atmosphere but does not reach the ground writes Universe Today.read more >>
