Scientists at the Indian Institute of Geomagnetism, in collaboration with international researchers, have made a groundbreaking discovery by detecting the existence of high-frequency plasma waves in the Martian Upper Atmosphere. Utilizing high-resolution electric field data from NASA’s MAVEN spacecraft, the researchers identified two distinct wave modes with frequencies both below and above the electron plasma frequency in the Martian magnetosphere. These waves, observed during a specific period in 2015, provide valuable insights into how electrons gain or dissipate energy in the Martian plasma environment. The findings, published in the Astronomy & Astrophysics Journal, open new avenues for understanding plasma processes on Mars.
