NASA’s Perseverance rover has recorded the first strong evidence of lightning on Mars, capturing faint electrical “zaps” during dust storms. These sounds were picked up as the rover studied the Red Planet’s atmosphere and weather patterns.
A new study published in Nature confirms that these zaps are tiny sparks of electricity created when dust particles collide with each other. As the particles rub together, they release small electrical discharges—similar to static electricity on Earth.
Scientists explain that this happens often on Mars because of its thin atmosphere and unusual pressure levels. These conditions make dust storms extremely active, allowing static charges to build up easily. The research also shows that lightning-like activity is more common on Mars than previously believed.
The discovery is important because it helps answer long-standing questions about the Martian climate. Dust storms are known to shape weather patterns on Mars, and the presence of electrical activity may affect how these storms grow and move. It also provides clues about chemical reactions on the Martian surface, which could influence soil composition and the planet’s long-term atmospheric changes.
Researchers say that understanding lightning on Mars is not just exciting—it is useful for future missions. Electrical activity could affect equipment, communication systems, and even human habitats one day. Knowing how Mars behaves during dust storms will help scientists design safer technology for future explorers.
The finding marks another milestone for the Perseverance rover, which continues to provide valuable insights into Mars’ environment, weather, and potential for past life.
