Physicists Explain Mysterious “Discrete Aurora” on Mars

Scientists have learned how discrete aurora is formed on Mars. In a new study, the physicists report that the upstream solar wind properties interacting with the crustal magnetic fields found in Mars’ southern hemisphere strongly affect the formation and properties of the Martian discrete aurora. The research was led by Zachary Girazian, an associate research scientist in the University of Iowa Department of Physics and Astronomy.

Scientists Think They Know What Causes Mars's Planet-Encompassing Dust Storms

Mars is well-known for its seasonal dust storms, which can sometimes grow to encompass the entire planet. In June 2018, the dust storms became so severe that they obscured most of the planet's surface, causing NASA to lose contact with Opportunity, which eventually proved fatal to the record-breaking rover.

Dust Storms on Mars Happen When the Planet Can’t Release its Heat Fast Enough

Mars is well-known for its seasonal dust storms, which can sometimes grow to encompass the entire planet. In June 2018, the dust storms became so severe that they obscured most of the planet’s surface, causing NASA to lose contact with Opportunity, which eventually proved fatal to the record-breaking rover. Understanding these storms and what causes them is critical to ensuring that solar-powered robotic missions continue to operate and future crewed missions can remain safe.
