A team of Indian scientists has discovered the first evidence of solitary waves surrounding Mars. Through wave-particle interactions, these solitary waves regulate particle energization, plasma loss, and transport in the Martian magnetosphere.

Indian Institute of Geomagnetism (IIG) researchers found and reported solitary waves in the Martian magnetosphere using high-resolution electric field data acquired by the Langmuir Probe and Waves instrument on Nasa’s Mars Atmosphere and Volatile Evolution (MAVEN) satellite.

The study of 450 solitary wave pulses seen by the MAVEN spacecraft during its five orbits around Mars in February 2015 has been published in The Astrophysical Journal.

Plasma conditions on Earth and in interplanetary space support a range of electromagnetic and electrostatic waves. Using observations, theory, and simulations, plasma waves are extensively explored to improve our understanding of the ambient plasma conditions and fundamental physical processes operating in those locations.

According to researchers, the Earth resembles a big magnet, and its magnetic field shields us from the solar wind, which consists of high-velocity charged particles regularly generated by the Sun. However, Mars is an exception. Mars lacks an intrinsic magnetic field that would allow the high-velocity solar wind to interact directly with its atmosphere as an impediment to flow.

Even with a weak and thin magnetosphere like Mars’, theories imply that regular occurrences of solitary waves can be observed. However, they had remained concealed thus far. Due to the direct interaction of solar winds with the Martian atmosphere, researchers have discovered that the magnetosphere is feeble but very dynamic.

“Solitary waves are bipolar or unipolar electric field variations with constant amplitude-phase relationships. Their size and shape are less impacted by their reproduction. These pulses are predominantly observed in the dawn and afternoon twilight sectors between 1000 and 3500 kilometres above the surface of Mars “In a statement, the Ministry of Science and Technology stated.

As it is known that these waves are responsible for plasma energization and its transport in Earth’s magnetosphere, the team is investigating their involvement in the particle dynamics in the Martian magnetosphere and whether or not they play a role in the loss of atmospheric ions on Mars.

Web Desk for India Today The first indication of the existence of lone waves around Mars has been discovered by a team of Indian scientists. Through wave-particle interactions, these solitary waves, which are discrete electric field fluctuations in the Martian magnetosphere, regulate particle energization, plasma loss, and transport.

The Langmuir Probe and Waves instrument on NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) satellite gathered high-resolution electric field data that allowed researchers from the Indian Institute of Geomagnetism (IIG) to identify and describe the solitary waves in the Martian magnetosphere.

A variety of electromagnetic and electrostatic waves are supported by the plasma environments of Earth and planetary space. To improve our understanding of the ambient plasma conditions and fundamental physical processes taking place in those places, these plasma waves are extensively researched using observations, theory, and simulations.

According to researchers, the Earth resembles a massive magnet, and its magnetic field shields us from the solar wind, which is the Sun’s continual emission of high-speed charged particles. For Mars, things are different. The high-speed solar wind cannot directly interact with the atmosphere of Mars due to the lack of an inherent magnetic field on the Red Planet, acting as an obstruction in the flow.

According to theories, solitary waves can be frequently seen even in a weak and shallow magnetosphere, like the one on Mars. But up until now, they had stayed undercover. According to recent findings, the magnetosphere on Mars is dynamically weak but generated as a direct result of solar winds interacting directly with the planet’s atmosphere.

“Bipolar or monopolar solitary waves are unique electric field variations that exhibit constant amplitude-phase relationships. The propagation process has less of an impact on their size and shape. Around Mars, these pulses are primarily observed in the morning and afternoon-dusk sectors at altitudes of 1000-3500 km “According to a statement from the Ministry of Science and Technology.

The team is further examining these waves’ role in the particle dynamics in the Martian magnetosphere and whether they have any bearing on the loss of atmospheric ions on Mars because it is known that they are responsible for plasma energization and its transport in the Earth’s magnetosphere.
