NASA has recently discovered new signs of lightning on Mars, thanks to data gathered by two spacecraft: the MAVEN orbiter and the Perseverance rover. While lightning is a common occurrence on Earth, it has been challenging to detect on Mars due to the planet’s thin atmosphere and weak magnetic field. Scientists believe that lightning on Mars may manifest as glowing sparks caused by electrostatically charged dust in the atmosphere.
Recent research published in Science Advances on February 27, 2026, has provided possible evidence of a lightning strike on Mars that occurred in June 2015. The signature of this event was detected in data collected by NASA’s MAVEN mission. This discovery comes shortly after another study based on data from the Perseverance rover found evidence of electrical discharges during dust storms on the planet.
Confirming the presence of lightning on Mars is not only of scientific interest but also essential for understanding the potential impact on space technology and the role it plays in sparking chemical reactions that could contribute to the development of life. The detection of whistlers, a phenomenon associated with lightning strikes, in MAVEN’s data supports the hypothesis of lightning on Mars.
While the findings are exciting, challenges lie ahead in further research due to communication issues with the MAVEN spacecraft. Additionally, plans to deploy a lightning detector on the Rosalind Franklin Mars rover were disrupted by geopolitical events, leading to uncertainties about future missions.
