Martian

Scientists believe they have recorded electrical activity in the Martian atmosphere for the first time, suggesting the planet is capable of lightning.

The rover, which is named after British scientist Rosalind Franklin, is planned to touch down on the Martian surface in 2030.

Inside the planet's polar vortex, temperatures drop dramatically -- much colder than the air outside -- and the continuous darkness of the long Martian winter allows ozone levels in the atmosphere to rise sharply.

During the Martian winter, when temperatures plunge to around minus 120 degrees Celsius, ice accumulates on the dunes.

These winds stir up dust into swirling columns called dust devils—rotating plumes of air and fine particles that sweep across the Martian surface.
