Curious Mars

Mars: September 2017

The search for biology on neighbor planet Mars won't play out like a Hollywood movie starring little green men. Rather, many scientists agree if there was life on the Red Planet, it probably will present itself as fossilized bacteria.

Researchers have performed numerical simulations and compared the results to the composition of the ancient Martian atmosphere trapped in an old meteorite. The researchers have concluded that, 4 billion years ago, Mars had a dense atmosphere whose surface pressure was higher than 0.5 bar (50000 Pa).

River deposits exist across the surface of Mars and record a surface environment from over 3.5 billion years ago that was able to support liquid water at the surface.

he discovery of boron on Mars gives scientists more clues about whether life could have ever existed on the planet, according to a paper published today in the journal Geophysical Research Letters.
