First Map of Mars Electric Currents

The video discusses the MAVEN mission, which studies Mars' atmosphere and its evolution. It explores the role of magnetic fields in atmospheric retention, comparing Earth and Mars. MAVEN's data reveals how solar wind interacts with Mars, forming complex magnetic and electric current systems. These findings help understand atmospheric escape and the differences between Mars, Venus, and Earth.

What is the primary goal of the MAVEN mission?

How has the atmosphere of Mars changed over the past 4 billion years?

What role does a magnetic field play in a planet's atmosphere according to the text?

Describe the relationship between solar wind and the atmosphere of Mars.
