What Happened to Mars’ Atmosphere?

The Earth-like atmosphere that once existed on Mars seems to have been blown away by solar wind, according to new findings from NASA’s ongoing exploration of the red planet.

In a press conference Thursday, the space agency confirmed that solar wind played a major role in the disappearance of the Mars’ atmosphere and water.

The discovery, published in the journals Science and Geophysical Research Letters, sheds new light on how the planet evolved from having a warm and wet environment that might have hosted life to becoming the cold, arid world it is today. Solar winds did have the same effect on Earth due to our planet’s strong magnetic fields.
